Autoimmune Hepatitis: Causes, Symptoms, Diagnosis, and Treatment

Autoimmune hepatitis, often shortened to AIH, is a long-term inflammatory liver disease. It develops when an abnormal immune response targets liver cells and causes ongoing inflammation.

The condition is not caused by hepatitis A, B, or C viruses. It is not contagious, and it cannot spread through food, blood, sex, coughing, hugging, or ordinary household contact.

Some people have fatigue, joint discomfort, nausea, abdominal pain, or jaundice. Others have no noticeable symptoms and discover the condition after routine blood tests show elevated liver enzymes.

Autoimmune hepatitis can usually be controlled with medicines that reduce immune-system activity. Early diagnosis and effective treatment may prevent or limit fibrosis, cirrhosis, liver failure, and other complications.

However, AIH cannot be diagnosed from one symptom, antibody test, or liver-enzyme result. Diagnosis usually requires a combination of medical history, blood tests, imaging, exclusion of competing liver diseases, and liver-biopsy findings.

What Is Autoimmune Hepatitis?

Autoimmune hepatitis is an immune-mediated inflammatory liver disease. The immune system normally protects the body from infections and harmful substances. In AIH, immune activity becomes misdirected and causes inflammation in liver tissue.

The word hepatitis means inflammation of the liver. It does not automatically mean that the inflammation was caused by a virus.

Autoimmune hepatitis may:

• Develop gradually over months or years
• Appear suddenly as acute hepatitis
• Cause few or no symptoms
• Be discovered through abnormal liver blood tests
• Present after cirrhosis has already developed
• Rarely cause severe acute liver failure

AIH can affect children and adults. It occurs more often in females, but people of any sex, age, ethnicity, or background can develop it.

Is Autoimmune Hepatitis the Same as Viral Hepatitis?

No. Autoimmune hepatitis and viral hepatitis can both inflame the liver, but they have different causes and treatments.

Doctors normally test for viral hepatitis before confirming AIH because hepatitis B or C can also cause abnormal liver enzymes and inflammation.

Read the related guides to hepatitis B treatment and monitoring and hepatitis C testing and treatment.

What Causes Autoimmune Hepatitis?

The exact cause is unknown.

Researchers believe that AIH develops through a combination of:

• Genetic susceptibility
• Abnormal immune regulation
• One or more environmental or medical triggers

Most people cannot identify one event, infection, food, toxin, or medicine that definitely caused the condition.

Genetic Susceptibility

Certain human leukocyte antigen, or HLA, patterns are associated with a greater likelihood of autoimmune hepatitis. These genes help the immune system distinguish the body’s own tissues from foreign substances.

However, AIH is not normally inherited through one simple gene. Having a relative with AIH or another autoimmune condition does not mean that someone will inevitably develop it.

Possible Environmental Triggers

Researchers have investigated whether infections or other exposures may trigger an abnormal immune response in genetically susceptible people.

Associations do not prove that a particular infection directly causes AIH. In most patients, no specific trigger is identified.

Medicine-Related Autoimmune-Like Hepatitis

Some medicines and herbal products can cause liver injury that resembles autoimmune hepatitis. This is sometimes called drug-induced autoimmune-like hepatitis.

Reported examples include:

• Nitrofurantoin
• Minocycline
• Some immune-checkpoint inhibitor cancer treatments
• Selected other prescription medicines
• Certain herbal or dietary supplements

This condition may look similar to classic AIH in blood tests and liver-biopsy findings. Doctors review when the product was started, when liver tests changed, and whether inflammation improves after the suspected product is stopped.

Do not stop an essential medicine yourself. Suspected medicine-related liver injury requires professional evaluation and a safe alternative plan.

Who Can Develop Autoimmune Hepatitis?

Autoimmune hepatitis can affect:

• Children
• Teenagers
• Young adults
• Middle-aged adults
• Older adults
• People of any sex or ethnicity

It is more commonly diagnosed in females, but this pattern should not prevent clinicians from considering AIH in males or other patients with unexplained liver inflammation.

Some people have a personal or family history of autoimmune disease, but many do not.

Which Autoimmune Conditions Are Associated With AIH?

People with autoimmune hepatitis may also have another immune-mediated condition.

Associated conditions may include:

• Autoimmune thyroid disease
• Type 1 diabetes
• Celiac disease
• Inflammatory bowel disease
• Rheumatoid arthritis
• Sjögren disease
• Vitiligo
• Autoimmune skin conditions

The presence of another autoimmune condition does not confirm AIH. However, it may be an important part of the medical history when unexplained liver-test abnormalities are present.

Some patients have features of AIH together with primary biliary cholangitis or primary sclerosing cholangitis. These are sometimes described as variant or overlap syndromes and normally require specialist assessment.

Autoimmune Hepatitis Symptoms

Symptoms vary widely. Some people have no symptoms, while others become acutely unwell.

Common Possible Symptoms

• Persistent fatigue
• Joint pain or stiffness
• Nausea
• Reduced appetite
• Upper-right abdominal discomfort
• General weakness
• Itchy skin
• Dark urine
• Pale stools
• Yellow skin or eyes

Symptoms of More Advanced Liver Disease

• Easy bruising or bleeding
• Swollen ankles or legs
• Increasing abdominal swelling
• Loss of muscle
• Unexplained weight loss
• Visible blood vessels on the skin
• Confusion or unusual sleepiness
• Vomiting blood
• Black, tar-like stools

Acute or Severe Presentation

AIH can sometimes appear suddenly with marked jaundice, very high liver enzymes, impaired blood clotting, or acute liver failure.

Severe acute presentation requires urgent specialist assessment because corticosteroid treatment must be balanced against infection risk and other causes of acute liver injury.

Can AIH Occur Without Symptoms?

Yes. Some people are diagnosed after routine testing reveals elevated ALT or AST.

Feeling well does not prove that inflammation or fibrosis is absent. Follow-up blood tests and specialist appointments remain important even when symptoms improve.

Upper-right abdominal pain is not specific to AIH. Learn more about gallbladder pain versus liver-area pain, while remembering that an online comparison cannot establish the cause.

How Is Autoimmune Hepatitis Diagnosed?

No single test can diagnose autoimmune hepatitis.

A hepatologist normally combines:

• Medical history
• Symptoms and physical examination
• Liver blood tests
• Immunoglobulin G levels
• Autoantibody tests
• Tests for viral and metabolic liver diseases
• Medicine, supplement, and alcohol history
• Imaging
• Liver-biopsy findings

Medical History

The clinician may ask about:

• When symptoms began
• Previous liver-test results
• Prescription and nonprescription medicines
• Herbs, powders, teas, and supplements
• Alcohol intake
• Travel and infection exposure
• Other autoimmune conditions
• Family history
• Pregnancy or family-planning needs

Physical Examination

The examination may look for:

• Jaundice
• Liver or spleen enlargement
• Abdominal tenderness
• Fluid in the abdomen
• Swollen legs
• Skin signs of chronic liver disease
• Loss of muscle

Blood Tests Used for Autoimmune Hepatitis

ALT and AST

Alanine aminotransferase, or ALT, and aspartate aminotransferase, or AST, are enzymes that may rise when liver cells are inflamed or injured.

Markedly elevated levels may occur in AIH, but the degree of elevation does not always show how much fibrosis is present.

ALT and AST are also used to monitor response to treatment.

Immunoglobulin G

Immunoglobulin G, or IgG, is often elevated in autoimmune hepatitis.

An elevated IgG result can support the diagnosis, but it is not specific to AIH. A normal result does not completely exclude the disease, particularly in some acute presentations.

Autoantibody Testing

Autoantibodies that may be assessed include:

• Antinuclear antibody, or ANA
• Smooth-muscle antibody, or SMA
• Anti-liver kidney microsomal type 1 antibody, or anti-LKM1
• Anti-liver cytosol type 1 antibody, or anti-LC1
• Anti-soluble liver antigen/liver-pancreas antibody, or anti-SLA/LP

What a Positive ANA Does Not Mean

A positive ANA test does not diagnose autoimmune hepatitis.

ANA and other autoantibodies may be found in:

• Other autoimmune diseases
• Viral infections
• Other liver conditions
• Some healthy people

Some people with genuine autoimmune hepatitis may initially have negative standard autoantibody tests.

The 2025 EASL guidance no longer recommends treating antibody-based “type 1” and “type 2” AIH as clinically distinct diseases requiring different treatment strategies.

Other Liver and General Health Tests

Testing may include:

• Bilirubin
• Albumin
• Alkaline phosphatase
• Gamma-glutamyl transferase
• Platelet count
• Complete blood count
• INR or another clotting test
• Kidney function
• Blood glucose
• Pregnancy testing when relevant

Visit the Medical Tests and Screenings Hub for general help preparing questions about laboratory tests and screening.

Why Is a Liver Biopsy Important?

A liver biopsy remains a cornerstone of autoimmune hepatitis diagnosis.

During a biopsy, a clinician removes a small sample of liver tissue. A pathologist examines it under a microscope.

The biopsy may help:

• Support or challenge the diagnosis of AIH
• Show the pattern and severity of inflammation
• Identify interface hepatitis or other characteristic features
• Assess liver fibrosis or cirrhosis
• Identify another liver disease
• Recognize an overlap or variant syndrome
• Guide treatment decisions in uncertain cases

No individual biopsy feature is completely specific to AIH. The pathology must be interpreted together with blood tests, symptoms, medication history, and competing diagnoses.

Is Biopsy Required in Every Emergency?

In acute severe illness, the medical team may need to begin urgent evaluation and treatment while deciding whether and how a biopsy can be performed safely.

Blood-clotting problems, severe illness, or fluid in the abdomen may affect which biopsy technique is appropriate.

Can Biopsy Be Repeated?

A repeat biopsy may be considered when:

• The diagnosis remains uncertain
• Treatment response is unexpectedly poor
• Another liver disease is suspected
• Treatment withdrawal is being considered in a carefully selected patient

What Other Diseases Must Doctors Exclude?

Several conditions can resemble autoimmune hepatitis.

Evaluation may include testing for:

• Hepatitis A, B, C, or other viral infections
• Drug-induced liver injury
• Metabolic dysfunction-associated steatotic liver disease
• Alcohol-associated liver disease
• Wilson disease
• Primary biliary cholangitis
• Primary sclerosing cholangitis
• Hemochromatosis
• Celiac disease when relevant
• Acute bile-duct obstruction
• Other causes of acute or chronic hepatitis

Imaging may help assess liver structure, bile ducts, spleen size, cirrhosis, masses, or other explanations for abnormal liver tests. Imaging alone cannot confirm autoimmune hepatitis.

What Is the Treatment for Autoimmune Hepatitis?

The main goal of treatment is to suppress abnormal immune activity enough to stop liver inflammation and prevent progressive damage.

Treatment may:

• Improve symptoms
• Normalize ALT and AST
• Normalize IgG
• Prevent or reduce fibrosis
• Lower the risk of cirrhosis
• Reduce the risk of liver failure
• Improve long-term survival

Lifestyle changes alone cannot adequately suppress the immune attack. Food, activity, sleep, and alcohol avoidance may support general health, but they do not replace prescribed immunosuppressive treatment.

Main Autoimmune Hepatitis Medicines

Prednisone or Prednisolone

Prednisone or prednisolone is a corticosteroid used to reduce liver inflammation relatively quickly.

Treatment often starts with a higher dose and is gradually reduced as liver tests improve.

The aim is to use the lowest dose that controls the disease while limiting side effects.

Azathioprine

Azathioprine is an immunosuppressive medicine often used with a corticosteroid.

It acts more slowly than corticosteroids but may allow the steroid dose to be reduced. This is why it is sometimes called a steroid-sparing medicine.

Before or shortly after starting azathioprine, clinicians may assess TPMT or related enzyme activity or genetics because some patients have a greater risk of severe blood-cell toxicity.

Mycophenolate Mofetil

Mycophenolate mofetil is another immunosuppressive medicine.

The 2025 EASL guideline recognizes it as a viable first-line alternative to azathioprine in appropriately selected patients. It may also be used when azathioprine is not tolerated or does not provide an adequate response.

Mycophenolate can cause serious birth defects and pregnancy loss. It must not be used during pregnancy, and strict pregnancy-prevention planning is required.

What About Budesonide?

Older guidance sometimes presented budesonide as a steroid option for selected people without cirrhosis.

The 2025 EASL guideline no longer endorses budesonide as routine first-line therapy because of concerns about its overall effectiveness and safety.

Do not change an existing budesonide prescription based on this article. Treatment changes require specialist review of liver status, cirrhosis, response, and alternatives.

Medicines for Difficult-to-Control Disease

If standard treatment is not tolerated or does not control inflammation, a specialist may consider other medicines, such as:

• Tacrolimus
• Cyclosporine
• Mercaptopurine
• Selected biologic or advanced immunosuppressive therapies

These medicines require specialist prescribing and close monitoring. They are not appropriate for self-treatment or routine first-line use.

Autoimmune Hepatitis Medicine Comparison

This table provides general education. It cannot be used to choose a medicine, dose, or treatment combination.

How Is Treatment Response Monitored?

Monitoring is essential because symptoms alone do not show whether liver inflammation is controlled.

Clinicians may monitor:

• ALT and AST
• Immunoglobulin G
• Bilirubin
• Albumin
• INR
• Complete blood count
• Kidney function
• Medicine side effects
• Infections
• Treatment adherence
• Signs of fibrosis or cirrhosis

Complete Biochemical Response

A complete biochemical response generally means that liver enzymes and IgG have normalized with treatment.

The 2025 EASL guidance recommends assessing complete or insufficient response over a broader 6-to-12-month period rather than requiring every patient to meet the target at exactly six months.

Early improvement remains important. A lack of progress may lead the clinician to review:

• Whether doses are being taken correctly
• Whether the diagnosis is accurate
• Medicine intolerance
• Insufficient dosage
• Medicine interactions
• Another liver disease
• True treatment-resistant AIH

Are Autoantibodies Monitored Regularly?

Autoantibody levels are not usually the main day-to-day measure of treatment response.

ALT, AST, IgG, symptoms, medicine toxicity, and the overall clinical picture are generally more useful for routine monitoring.

Remission, Relapse, and Stopping Treatment

What Is Remission?

Remission means that the disease is controlled and liver inflammation has improved substantially.

Biochemical remission usually involves normalization of ALT, AST, and IgG.

Remission does not necessarily mean that the immune tendency has permanently disappeared.

How Long Does Treatment Continue?

Many people remain on treatment for several years. Some need lifelong immunosuppression.

The duration depends on:

• Response to treatment
• Previous relapses
• Cirrhosis
• Medicine tolerance
• Pregnancy plans
• Biochemical and sometimes biopsy findings

Can Treatment Ever Be Stopped?

A carefully supervised treatment-withdrawal attempt may be considered in selected patients who have maintained complete biochemical remission for an extended period.

The clinician may consider repeat liver biopsy before withdrawal, particularly when there is uncertainty about persistent microscopic inflammation.

Do not stop treatment because:

• You feel well
• Your liver enzymes improved once
• You are worried about long-term side effects
• You become pregnant
• You want to try a natural alternative

How Common Is Relapse?

Most patients who stop medicine eventually relapse and need treatment again.

Relapse may occur without obvious symptoms. Blood tests may show rising ALT, AST, or IgG before the person feels unwell.

Monitoring must continue after treatment withdrawal because relapse can occur quickly and may be severe.

Treatment Side Effects and Preventive Care

Immunosuppressive treatment can be highly effective, but it requires proactive side-effect prevention.

Corticosteroid Side Effects

Possible effects include:

• Increased appetite and weight gain
• Higher blood sugar
• High blood pressure
• Mood changes
• Sleep disturbance
• Acne or skin changes
• Cataracts or glaucoma
• Reduced bone density
• Muscle weakness
• Increased infection risk

Azathioprine Side Effects

Possible effects include:

• Nausea
• Low white blood cells
• Low platelets
• Liver-test changes
• Pancreatitis
• Infection risk
• Greater sensitivity to sunlight
• A small increase in certain cancer risks with long-term immunosuppression

Mycophenolate Side Effects

Possible effects include:

• Nausea or vomiting
• Diarrhea
• Abdominal discomfort
• Reduced blood-cell counts
• Infection risk
• Medicine interactions
• Pregnancy loss or serious birth defects

Checks Before Immunosuppressive Treatment

The medical team may review:

• Hepatitis A and B vaccination status
• Current or previous hepatitis B infection
• Hepatitis C and HIV status
• Tuberculosis or other infection risk when relevant
• Blood counts
• Kidney function
• TPMT or related testing before azathioprine
• Bone health
• Blood pressure
• Blood sugar
• Eye health
• Pregnancy status and contraception needs

Vaccines

Ask which vaccinations are recommended before and during immunosuppressive treatment.

Live vaccines may not be safe with some immunosuppressive medicines. Do not receive a live vaccine without checking with the prescribing team.

Bone Protection

Long-term corticosteroids may reduce bone density.

The care team may consider:

• Calcium and vitamin D intake
• Vitamin D testing
• Bone-density scanning
• Weight-bearing or resistance exercise when safe
• Prescription bone-protection medicine for higher-risk patients

Do not start high-dose calcium or vitamin D without checking for kidney disease, kidney stones, high calcium, medicine interactions, and individual requirements.

Skin Protection

Some immunosuppressive medicines increase sensitivity to sunlight and may raise long-term skin-cancer risk.

Use sun protection and ask whether periodic skin checks are appropriate.

Autoimmune Hepatitis, Pregnancy, and Family Planning

Pregnancy should be planned with the hepatology and obstetric teams whenever possible.

Important principles include:

• Do not stop AIH medicine simply because pregnancy occurs
• Active liver inflammation may be more dangerous than appropriately selected treatment
• Medicine choices should be reviewed before conception
• Pregnancy may change liver-test and medicine-monitoring needs
• AIH can flare after delivery

Mycophenolate and Pregnancy

Mycophenolate must not be used during pregnancy because it is associated with pregnancy loss and serious birth defects.

People who could become pregnant need reliable contraception and a specialist-approved transition plan before attempting conception.

Do not stop mycophenolate without medical guidance, because uncontrolled autoimmune hepatitis can also be dangerous.

Azathioprine and Corticosteroids

Azathioprine and selected corticosteroids may be continued or used during pregnancy when the specialist determines that the benefits outweigh the risks.

Decisions depend on disease activity, previous relapse, liver health, medicine response, and pregnancy history.

After Delivery

The postpartum period carries a risk of AIH flare. Liver tests and symptoms may need closer monitoring after birth.

Breastfeeding advice depends on the exact medicine and dose. Discuss each medicine with the hepatology, obstetric, pediatric, and pharmacy teams.

Autoimmune Hepatitis, Cirrhosis, and Liver Cancer

Untreated or inadequately controlled AIH can cause progressive fibrosis and cirrhosis.

Cirrhosis may lead to:

• Portal hypertension
• Fluid in the abdomen
• Swollen legs
• Bleeding from enlarged veins in the digestive tract
• Hepatic encephalopathy
• Liver failure
• Increased liver-cancer risk

Liver-Cancer Surveillance

People with cirrhosis generally require ongoing hepatocellular carcinoma surveillance.

This often involves liver ultrasound approximately every six months, sometimes with an alpha-fetoprotein blood test.

The exact schedule and imaging method should be set by the liver specialist.

Does Treatment Remove Cancer Risk?

Effective control of inflammation reduces liver-disease progression, but cirrhosis-related liver-cancer risk does not disappear completely.

Surveillance should continue when recommended, even if liver enzymes normalize.

When Is Liver Transplantation Considered?

Most people with autoimmune hepatitis do not need a liver transplant.

Transplant evaluation may be needed when AIH causes:

• Acute liver failure
• Decompensated cirrhosis
• Progressive liver failure despite treatment
• Selected cases of liver cancer
• Life-threatening complications of advanced liver disease

Autoimmune hepatitis can recur after transplantation, but specialist immunosuppressive treatment and monitoring can manage this risk.

Daily Care With Autoimmune Hepatitis

Daily habits support general health and reduce additional liver stress. They do not replace immunosuppressive medicine.

Follow Your Treatment Plan

• Take medicine at the prescribed time
• Do not alter steroid doses independently
• Complete scheduled blood tests
• Report side effects early
• Refill prescriptions before they run out
• Tell every clinician that you use immunosuppressive medicine

Alcohol

Alcohol can add further liver injury. Many people with AIH, fibrosis, or cirrhosis are advised to avoid it completely.

Ask the clinician who knows your liver status whether any alcohol is considered safe.

A person who drinks heavily or may be physically dependent should seek medical advice before suddenly stopping because alcohol withdrawal can be dangerous.

Balanced Nutrition

There is no special diet that cures autoimmune hepatitis.

A balanced eating pattern may include:

• Vegetables
• Whole fruit
• Beans and lentils
• Whole grains when suitable
• Fish
• Eggs, poultry, tofu, or other suitable protein foods
• Nuts and seeds in appropriate portions
• Unsaturated fats such as olive oil

Food needs may change with cirrhosis, fluid retention, diabetes, kidney disease, osteoporosis, or steroid-related weight gain.

For general food ideas, read foods that may fit a liver-supportive eating pattern and visit the Kidney and Liver Health Foods Hub.

Exercise and Physical Activity

Regular activity may support:

• Bone health
• Muscle strength
• Blood sugar
• Blood pressure
• Mood
• Weight management

Ask for individualized advice if you have severe fatigue, cirrhosis, fluid retention, muscle loss, osteoporosis, balance problems, or another condition that affects exercise safety.

Medicines, Pain Relief, and Supplements

Do not assume that all people with AIH must avoid acetaminophen or paracetamol. It may be appropriate at a clinician-approved dose for some patients.

Ask a clinician or pharmacist:

• Which pain reliever is safest for you
• What maximum daily amount is appropriate
• Whether alcohol changes the risk
• Whether another medicine contains the same active ingredient

Avoid accidentally combining several cold, flu, or pain products containing acetaminophen or paracetamol.

Tell the care team about every herb, supplement, detox tea, bodybuilding product, and weight-loss product. Some products can injure the liver or interact with immunosuppressive medicine.

Infection Precautions

Immunosuppressive medicines may increase infection risk.

Contact the healthcare team if you develop:

• Persistent fever
• Severe sore throat
• New cough or shortness of breath
• Painful urination
• Unusual bruising
• A spreading rash
• Severe diarrhea or vomiting

Simple 7-Day AIH Care Organization Plan

This plan does not replace medical treatment. It may help you prepare for appointments and follow the prescribed plan more reliably.

Daily Autoimmune Hepatitis Checklist

• Did I take my medicine exactly as prescribed?
• Did I avoid changing my steroid dose independently?
• Did I record any new symptoms or side effects?
• Did I avoid unverified liver-cleanse products?
• Did I follow my clinician’s alcohol guidance?
• Did I eat a balanced meal?
• Did I move in a safe and appropriate way?
• Did I protect myself from excessive sun exposure?
• Did I keep my blood-test and appointment schedule?
• Did I contact my care team about possible infection?

Questions to Ask Your Hepatologist

• Which findings support my autoimmune hepatitis diagnosis?
• What did my liver biopsy show?
• Do I have liver fibrosis or cirrhosis?
• Could a medicine or supplement be causing autoimmune-like liver injury?
• Have viral hepatitis and other liver diseases been excluded?
• What do my ALT, AST, IgG, ANA, and SMA results mean?
• Why is this treatment combination recommended for me?
• How quickly should my liver tests improve?
• How often will I need blood tests?
• Do I need TPMT or another test before azathioprine?
• Which side effects should I report immediately?
• Do I need bone-density, eye, skin, or infection monitoring?
• Which vaccines are recommended?
• Should I avoid alcohol completely?
• Which pain medicines and supplements are safe?
• How does my treatment affect pregnancy or breastfeeding?
• Could treatment ever be stopped safely?
• Do I need liver-cancer surveillance?
• Which symptoms require emergency care?

Key Takeaway

Autoimmune hepatitis is a chronic inflammatory liver disease caused by an abnormal immune response. It is not contagious and is not the same as hepatitis B or C.

Symptoms may include fatigue, joint pain, nausea, abdominal discomfort, dark urine, and jaundice, but many people have no symptoms.

No single test confirms AIH. Diagnosis normally combines liver enzymes, IgG, autoantibodies, exclusion of competing liver diseases, imaging, and usually liver biopsy.

Treatment commonly uses a corticosteroid with azathioprine or another immunosuppressive medicine. The 2025 EASL guidance recognizes mycophenolate as a first-line alternative for appropriate patients and no longer endorses budesonide as routine first-line therapy.

Many people require treatment for years or longer. Do not stop medicine because symptoms improve or liver tests normalize once. Relapse is common after treatment withdrawal.

Recommended next step: Gather your blood-test, imaging, medicine, and biopsy records and review them with a hepatologist who can confirm the diagnosis and create an individualized treatment and monitoring plan.

Frequently Asked Questions About Autoimmune Hepatitis

What causes autoimmune hepatitis?

The exact cause is unknown. Genetic susceptibility, abnormal immune regulation, and possible environmental or medicine-related triggers may contribute. Most people do not have one identifiable cause.

Is autoimmune hepatitis contagious?

No. Autoimmune hepatitis is not caused by a contagious virus and cannot spread through blood, sex, food, coughing, hugging, or ordinary household contact.

Is autoimmune hepatitis the same as hepatitis B or C?

No. Autoimmune hepatitis is caused by abnormal immune activity. Hepatitis B and C are viral infections. They require different diagnostic tests and treatments.

What are the early symptoms of autoimmune hepatitis?

Possible symptoms include fatigue, joint pain, nausea, poor appetite, upper-right abdominal discomfort, dark urine, pale stools, itching, and jaundice. Many people have no symptoms.

Can autoimmune hepatitis occur without symptoms?

Yes. Some people are diagnosed after routine blood tests reveal elevated liver enzymes. Significant inflammation or fibrosis may be present even when the person feels well.

Which blood tests are used for autoimmune hepatitis?

Tests may include ALT, AST, bilirubin, albumin, INR, immunoglobulin G, ANA, SMA, anti-LKM1, anti-LC1, anti-SLA/LP, blood counts, kidney tests, and tests that exclude viral or other liver diseases.

Can a positive ANA test diagnose autoimmune hepatitis?

No. ANA may be positive in other autoimmune diseases, infections, liver conditions, and some healthy people. Diagnosis requires the complete clinical, laboratory, and biopsy picture.

Is a liver biopsy required for autoimmune hepatitis?

A liver biopsy is required or strongly recommended in most suspected cases because it supports diagnosis, evaluates inflammation and fibrosis, and helps exclude competing or overlapping liver diseases.

What medicines treat autoimmune hepatitis?

Treatment commonly uses prednisone or prednisolone with azathioprine. Mycophenolate mofetil may be used as a first-line alternative or when azathioprine is unsuitable. Other specialist medicines may be used for difficult-to-control disease.

How long does autoimmune hepatitis treatment last?

Treatment commonly continues for several years. Some people require lifelong immunosuppression, particularly after relapse, cirrhosis, or difficulty maintaining remission.

Can autoimmune hepatitis go into remission?

Yes. Many people achieve biochemical remission, meaning liver enzymes and IgG normalize with treatment. Remission does not guarantee that the disease will remain inactive without medicine.

Can autoimmune hepatitis treatment ever be stopped?

A carefully supervised withdrawal attempt may be considered after sustained complete remission in selected patients. Most people relapse after treatment is stopped, so close blood-test monitoring is essential.

What happens if autoimmune hepatitis is untreated?

Untreated inflammation can cause progressive fibrosis, cirrhosis, liver failure, and an increased risk of liver cancer in people who develop cirrhosis.

Can autoimmune hepatitis return after remission?

Yes. Relapse is common, especially after treatment withdrawal. Liver enzymes and IgG may rise before symptoms appear.

How is autoimmune hepatitis managed during pregnancy?

Pregnancy should be planned with hepatology and obstetric teams. Do not stop medicine independently. Mycophenolate must not be used during pregnancy, while other medicines may be continued when specialists determine they are appropriate.

When is a liver transplant needed?

Transplantation may be considered for acute liver failure, decompensated cirrhosis, progressive liver failure despite treatment, or selected cases of liver cancer.

When should someone seek urgent medical care?

Seek urgent care for severe jaundice, vomiting blood, black stools, severe confusion, fainting, rapidly increasing abdominal swelling, severe weakness, difficulty breathing, unusual sleepiness, or rapidly worsening illness.
