Quick Answer: Can You Improve Kidney Function?
How to improve kidney function safely depends on why the kidneys are not working normally. Kidney test results may improve when a reversible problem, such as dehydration, infection, urinary blockage, uncontrolled blood pressure, high blood glucose, or a medicine effect, is identified and treated.
Established chronic kidney disease usually cannot be repaired with a special food, drink, supplement, or kidney cleanse. However, appropriate medicines, blood-pressure and diabetes control, regular eGFR and urine albumin tests, an individualized eating plan, safe physical activity, smoking cessation, and medicine review can help protect the kidney function that remains.
Do not force water or automatically restrict protein, potassium, phosphorus, or fluids. These needs depend on kidney function, blood results, medicines, nutritional status, swelling, urine output, and dialysis status.
Seek urgent medical help for a major reduction in urine, severe breathlessness, chest pain, confusion, fainting, rapidly worsening swelling, or persistent vomiting and dehydration.
When Kidney Symptoms Need Urgent Medical Care
Contact an urgent medical service if you have:
- A sudden or major reduction in urine output
- Rapidly worsening swelling of the legs, hands, face, or abdomen
- Persistent vomiting or diarrhea
- Severe dehydration, dizziness, or weakness
- Visible blood in the urine
- Fever with urinary symptoms
- Severe pain in the side or back
- A rapidly rising creatinine result
- Severe or difficult-to-control blood pressure
Call your local emergency number or go to the nearest emergency department, emergency room, or A&E department for:
- Severe shortness of breath
- Chest pain or pressure
- Confusion or difficulty waking
- A seizure
- Fainting or collapse
- Severe muscle weakness
- Dangerous-feeling heart palpitations
- Very little or no urine with serious illness
- Cold, pale, blue, grey, or mottled skin
These symptoms may indicate acute kidney injury, serious fluid overload, dangerously high potassium, infection, urinary obstruction, or another medical emergency.

What Does Kidney Function Mean?
Kidney function describes how well the kidneys perform their essential jobs.
Healthy kidneys:
- Filter waste from the blood
- Remove excess fluid
- Balance sodium, potassium, phosphorus, and other minerals
- Help regulate blood pressure
- Maintain acid and base balance
- Support red-blood-cell production
- Activate vitamin D for bone health
- Help remove or process some medicines
Kidney function cannot be judged by urine appearance or symptoms alone. Early chronic kidney disease often causes no noticeable symptoms.
Blood and urine tests are needed to assess filtration and kidney damage.
Can Damaged Kidneys Repair Themselves?
The answer depends on the type and cause of the kidney problem.
Acute Kidney Injury
Acute kidney injury, or AKI, is a sudden reduction in kidney function. Kidney tests may improve when the cause is treated promptly.
Possible causes include:
- Dehydration
- Severe infection
- Low blood pressure
- Medicine toxicity
- Urinary blockage
- Major surgery
- Heart or liver failure
Chronic Kidney Disease
Chronic kidney disease, or CKD, means that kidney structure or function has remained abnormal for at least three months.
Established scarring often cannot be reversed. Treatment aims to:
- Protect remaining kidney function
- Slow further decline
- Reduce albumin leaking into urine
- Lower cardiovascular risk
- Treat complications
- Delay or prevent kidney failure
No single food, drink, detox, or supplement has been shown to rebuild chronically scarred kidney filters.
If kidney disease has already been diagnosed, read Kidney Disease Treatment: CKD Tests, Medicines, Diet, and Daily Care.
What Can Cause Kidney Function to Decline Temporarily?
A creatinine increase or eGFR decrease may sometimes be related to a reversible or temporary problem.
| Potential cause | How it may affect kidney results | Possible response |
|---|---|---|
| Dehydration | Reduces blood flow to the kidneys | Careful fluid replacement and treatment of the cause |
| Vomiting or diarrhea | Causes fluid and electrolyte loss | Prompt assessment and rehydration when appropriate |
| Severe infection | Can reduce circulation and trigger inflammation | Urgent infection treatment and monitoring |
| Urinary obstruction | Prevents normal urine drainage | Imaging and relief of the blockage |
| NSAIDs or another medicine | May reduce kidney blood flow or cause direct injury | Medicine review by a clinician or pharmacist |
| Uncontrolled blood pressure | Damages small kidney blood vessels | Individualized blood-pressure treatment |
| Very high blood glucose | Contributes to dehydration and kidney stress | Diabetes assessment and treatment |
| Heart failure | May reduce effective circulation and cause fluid retention | Coordinated heart and kidney treatment |
A person cannot determine the cause from one creatinine or eGFR value. New or rapidly worsening results need medical review.
Which Tests Show Whether Kidney Function Is Improving?
| Test | What it measures | Why it matters |
|---|---|---|
| Serum creatinine | A waste product measured in blood | Used to calculate estimated kidney filtration |
| eGFR | Estimated glomerular filtration rate | Shows the kidney-function category and change over time |
| UACR | Albumin relative to creatinine in urine | Detects kidney damage and helps estimate progression risk |
| Urinalysis | Blood, protein, infection, glucose, and other findings | May identify kidney damage or another urinary condition |
| Blood pressure | Pressure within the circulation | High pressure can damage kidney blood vessels |
| Potassium and bicarbonate | Electrolyte and acid balance | Helps guide medicine, diet, and urgent treatment |
| A1C or blood glucose | Current or average glucose level | Important when diabetes or prediabetes is present |
| Kidney ultrasound | Kidney size, structure, cysts, stones, and obstruction | May help identify the cause of abnormal function |
Trends across several measurements are more useful than one isolated result.
Creatinine may be affected by muscle mass, diet, hydration, medicines, supplements, and acute illness. Cystatin C may be used in selected situations to improve eGFR assessment.
What Do eGFR and UACR Mean?
What Is eGFR?
Estimated glomerular filtration rate, or eGFR, estimates how effectively the kidneys filter blood.
It is commonly reported in millilitres per minute per 1.73 square meters of body-surface area.
An eGFR of 90 or higher does not automatically rule out CKD when albuminuria or another marker of kidney damage is present.
What Is UACR?
Urine albumin-to-creatinine ratio, or UACR, checks whether albumin is leaking into urine.
It may be reported as:
- Milligrams per gram, or mg/g
- Milligrams per millimole, or mg/mmol
Albuminuria may appear before eGFR becomes low. It is therefore an important part of kidney-risk assessment.
Why Do Tests Need to Be Repeated?
Exercise, fever, infection, menstruation, dehydration, uncontrolled blood glucose, and acute illness can temporarily affect kidney or urine results.
CKD is generally confirmed when abnormalities persist for at least three months or when another established marker of chronic kidney damage is present.
For a full explanation of chronic disease and staging, read Chronic Kidney Disease: Causes, Symptoms, and Treatments.
10 Daily Steps That May Protect Kidney Function
1. Know Your eGFR and UACR
Ask for both results and whether they are stable, improving, or declining.
Also ask how often the tests should be repeated.
2. Control Blood Pressure
Take prescribed medicine, reduce excess sodium, stay active, and monitor blood pressure when advised.
Use a validated upper-arm monitor with the correct cuff size.
3. Manage Blood Glucose
If you have diabetes, follow an individualized glucose plan and attend regular kidney, eye, foot, and cardiovascular checks.
4. Take Kidney-Protective Medicines Correctly
Some people benefit from an ACE inhibitor, ARB, SGLT2 inhibitor, or another kidney- and heart-protective medicine.
Take it as prescribed and complete requested creatinine and potassium monitoring.
5. Review Pain Medicines and Supplements
Tell a clinician or pharmacist about every prescription, over-the-counter medicine, vitamin, protein powder, creatine product, and herbal remedy.
6. Reduce Sodium and Highly Processed Food
Choose more minimally processed meals and compare sodium on food labels.
7. Follow Individualized Nutrition Advice
Do not copy another person's protein, potassium, phosphorus, or fluid restrictions.
8. Stay Physically Active
Aim for regular moderate activity according to your cardiovascular health, strength, mobility, and fall risk.
9. Stop Smoking
Smoking damages blood vessels and raises kidney and cardiovascular risk.
10. Attend Regular Medical Follow-Up
Monitoring can identify falling eGFR, rising albuminuria, high potassium, anemia, acidosis, and other problems before severe symptoms develop.
How Does Blood Pressure Affect Kidney Function?
High blood pressure can both cause kidney damage and become harder to control as kidney function declines.
Controlling it may help:
- Reduce pressure inside kidney filters
- Lower albuminuria
- Slow CKD progression
- Reduce heart attack and stroke risk
- Reduce heart-failure risk
Blood-pressure targets should be individualized. Age, dizziness, falls, frailty, cardiovascular disease, pregnancy, and the method used to measure blood pressure all matter.
Do not increase, reduce, or stop blood-pressure medicine because of a single home reading.
How Does Diabetes Affect Kidney Function?
High blood glucose can damage the small blood vessels that filter blood inside the kidneys.
Kidney protection may include:
- Individualized glucose goals
- Regular eGFR and UACR tests
- Blood-pressure treatment
- A SGLT2 inhibitor when suitable
- Metformin when kidney function and other factors allow it
- A GLP-1 receptor agonist for selected people
- Cardiovascular-risk management
- Nutrition and physical activity
Kidney disease can change how diabetes medicines are removed from the body and may increase the risk of low blood sugar.
Read Diabetes and Kidney Disease: Testing, Treatment, and Prevention.
Which Medicines May Protect Kidney Function?
The appropriate medicine depends on the cause of kidney disease, eGFR, UACR, blood pressure, potassium, diabetes, heart failure, pregnancy potential, and other medicines.
ACE Inhibitors and ARBs
Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers may lower blood pressure, reduce albuminuria, and slow progression in suitable people.
Creatinine and potassium are usually monitored after treatment begins or the dose changes.
ACE inhibitors and ARBs should not normally be combined with each other.
SGLT2 Inhibitors
Sodium-glucose cotransporter-2 inhibitors may protect kidney and heart health in many eligible adults with CKD, including some people who do not have diabetes.
Suitability depends on factors such as eGFR, albuminuria, heart failure, diabetes, infection risk, and other health conditions.
Nonsteroidal Mineralocorticoid Receptor Antagonists
This medicine class may be considered for selected adults with type 2 diabetes, persistent albuminuria, appropriate kidney function, and normal potassium despite standard care.
GLP-1 Receptor Agonists
A long-acting GLP-1 receptor agonist may be appropriate for selected people with type 2 diabetes and CKD when individualized glucose and cardiovascular goals have not been met.
Other Medicines
Depending on the condition, treatment may also include:
- Diuretics
- Statins
- Iron treatment
- Medicine for anemia
- Potassium-lowering treatment
- Alkali treatment for selected metabolic acidosis
- Medicine for CKD-related mineral and bone problems
These medicines are not appropriate for every person with reduced kidney function.
Which Medicines and Supplements Can Harm Kidney Function?
Kidney disease can change how medicines are removed from the body. Some products require a lower dose, a longer interval, or an alternative.
Ask a clinician or pharmacist before using:
- Ibuprofen
- Naproxen
- Another nonsteroidal anti-inflammatory drug
- Cold and flu products containing an NSAID
- Magnesium-containing antacids or laxatives
- Potassium supplements
- Salt substitutes containing potassium chloride
- Creatine supplements
- High-dose protein powders
- Herbal kidney cleanses or detoxes
- Unregulated weight-loss or bodybuilding products
NSAIDs may reduce protective blood flow to the kidneys. Risk may be higher during dehydration, infection, low blood pressure, heart failure, or use of interacting medicines.
Do not stop a prescribed kidney-protective medicine without contacting the prescriber.
What Should You Do During Vomiting, Diarrhea, or Fever?
Acute illness can increase dehydration and acute kidney-injury risk.
Ask your care team for a personalized sick-day medicine plan. Do not apply a blanket internet rule to every prescription.
What Is the Best Diet for Kidney Function?
There is no single kidney diet that is correct for everyone.
The safest eating plan depends on:
- The cause and stage of kidney disease
- eGFR and UACR
- Blood potassium and phosphorus
- Blood pressure and swelling
- Diabetes
- Appetite, weight, and muscle mass
- Medicines
- Dialysis or transplant status
A balanced pattern often emphasizes minimally processed foods, vegetables and fruit in suitable amounts, whole grains, healthy fats, and an individualized amount of protein.
No individual food repairs chronically damaged kidney tissue.
Protein, sodium, potassium, phosphorus, and fluids should be adjusted to medical and laboratory needs.
Read Diet for Kidney Disease: Foods and a Safer Eating Guide.
How Much Sodium Should You Eat?
For many adults with CKD, guidance suggests less than 2 grams of sodium per day, equivalent to approximately 5 grams of salt.
Reducing sodium may support:
- Blood-pressure control
- Reduced swelling
- Better response to some blood-pressure medicines
- Reduced thirst when fluids are limited
Common high-sodium sources include:
- Processed meat
- Fast food
- Packaged soup
- Instant noodles
- Salty snacks
- Commercial sauces
- Pickled foods
- Many frozen meals
Sodium restriction is not suitable for every kidney disorder. People with sodium-wasting conditions need individualized advice.
Should You Restrict Protein?
Protein needs depend on kidney function, dialysis, age, weight, pregnancy, nutrition, muscle mass, and illness.
For many metabolically stable adults with CKD who are not receiving dialysis, guidance suggests approximately 0.8 grams of protein per kilogram of body weight per day.
Very high protein intake may be inappropriate for people at risk of CKD progression.
Restricting protein too much may cause:
- Malnutrition
- Muscle loss
- Weakness
- Poor recovery from illness
Dialysis commonly increases protein needs. Frail, pregnant, undernourished, and acutely ill people also require different advice.
A very-low-protein plan should only be used with close kidney and dietitian supervision.
Should You Restrict Potassium?
Do not restrict potassium automatically because you have kidney disease.
The decision depends on:
- Blood-potassium results
- Kidney function
- Medicines
- Diabetes control
- Metabolic acidosis
- Constipation
- Food processing and additives
- Dialysis type
Many potassium-containing foods also provide fiber, vitamins, and other important nutrients.
When potassium is high, a renal dietitian may first review:
- Potassium additives
- Salt substitutes
- Portion sizes
- Constipation
- Medicine interactions
- Food preparation methods
Severe high potassium can affect the heart and may cause weakness, palpitations, collapse, or no symptoms at all.
Should You Restrict Phosphorus?
Phosphorus restriction is generally based on blood tests, CKD stage, parathyroid hormone, bone health, and the overall eating pattern.
Do not automatically eliminate all dairy, beans, nuts, seeds, or whole grains.
Phosphate additives in highly processed food may be absorbed more readily than phosphorus naturally present in food.
Common additive-containing products may include:
- Processed meat
- Cola
- Processed cheese
- Some baking mixes
- Fast food
- Some packaged drinks
Ingredient names containing “phos” may indicate a phosphate additive.
Phosphate binders should only be used when prescribed and are usually taken with meals according to instructions.
How Much Water Should You Drink for Kidney Health?
There is no universal eight-glass, 1.5-liter, or 2-liter rule for everyone.
Fluid needs depend on:
- Kidney function
- Urine output
- Swelling
- Heart function
- Blood sodium
- Diuretic use
- Dialysis
- Weather and activity
- Vomiting, diarrhea, or fever
People with early, stable CKD often do not need a fluid restriction unless another condition requires one.
People with low urine output, severe swelling, heart failure, kidney failure, or dialysis may need a defined daily fluid target.
Drinking excessive water does not restore damaged kidney filters or automatically increase eGFR.
Follow your healthcare team's fluid advice instead of forcing water.
Do Cranberry Juice, Green Tea, Beet Juice, or Lemon Water Improve Kidney Function?
Cranberry Juice
Cranberry products are studied mainly for recurrent UTI prevention in selected people. They do not restore kidney filtration or treat established CKD.
Many cranberry drinks contain added sugar, and concentrated products may interact with medicines.
Green Tea
Green tea can be consumed as a beverage by many people, but it has not been proven to repair kidney damage.
Concentrated green-tea extracts are different from brewed tea and may cause medicine interactions or other adverse effects.
Beet Juice
Beet juice does not restore damaged kidney filters. It can contain significant potassium and natural sugar, which may matter for some people with CKD or diabetes.
Lemon Water
Lemon water does not treat CKD or dissolve every kidney stone.
Citrate from citrus may be included in an individualized prevention plan for certain stone types, but stone treatment depends on urine testing, stone composition, kidney function, and other factors.
Kidney Detox Drinks
No detox drink has been shown to cleanse or regenerate the kidneys. Some herbal mixtures contain undeclared ingredients, excessive potassium, or substances that can damage the kidneys.
Can Exercise Improve Kidney Health?
Exercise does not regrow damaged kidney tissue, but regular activity can support several factors that protect the kidneys.
Potential benefits include:
- Lower blood pressure
- Improved blood-glucose control
- Better cardiovascular fitness
- Improved muscle strength
- Weight management
- Better sleep and mood
- Reduced sedentary time
Guidance recommends approximately 150 minutes of moderate-intensity activity each week for many adults with CKD, or an amount compatible with cardiovascular health and physical tolerance.
Appropriate activities may include:
- Walking
- Cycling
- Swimming
- Resistance exercise
- Chair-based activity
- Stretching and mobility work
Start gradually if you are inactive, frail, anemic, breathless, at risk of falls, or receiving dialysis.
Read Regular Walking Benefits for Physical and Mental Health.
Can Sleep and Stress Management Protect the Kidneys?
Stress reduction and adequate sleep do not directly repair kidney filters, but they may support:
- Blood-pressure control
- Blood-glucose management
- Medicine adherence
- Physical activity
- Eating habits
- Mental health
- Quality of life
Helpful approaches may include:
- A regular sleep schedule
- Breathing exercises
- Mindfulness
- Counseling
- Kidney support groups
- Social-work assistance
Persistent anxiety, depression, insomnia, or difficulty coping deserves professional support.
When Should You See a Nephrologist?
A referral to a kidney specialist may be appropriate for:
- Advanced kidney disease
- Rapidly falling eGFR
- Substantial albuminuria
- Persistent blood in urine from a suspected kidney cause
- Resistant high blood pressure
- Repeated high potassium
- Persistent metabolic acidosis
- Suspected glomerulonephritis
- Polycystic or inherited kidney disease
- Unexplained kidney dysfunction
- Preparation for dialysis or transplantation
Referral thresholds differ between countries and may also use a kidney-failure risk calculation.
What Should You Avoid Doing?
- Do not assume one low eGFR result proves permanent kidney damage.
- Do not try to raise eGFR by forcing excessive water.
- Do not follow a kidney detox or cleanse.
- Do not take creatine or high-dose protein supplements without checking safety.
- Do not restrict potassium or phosphorus without a reason.
- Do not follow a very-low-protein diet without supervision.
- Do not use NSAIDs regularly without checking kidney safety.
- Do not stop a kidney-protective prescription independently.
- Do not ignore vomiting, diarrhea, reduced urine, or rapidly worsening swelling.
- Do not rely on juice, tea, lemon water, or one food to repair the kidneys.
How Should You Prepare for a Kidney Appointment?
Bring or record:
- Recent creatinine and eGFR results
- Urine albumin or UACR results
- Home blood-pressure readings
- Blood-glucose readings when relevant
- Every prescription medicine
- Over-the-counter medicines and supplements
- Changes in urine output
- Swelling or breathlessness
- Appetite and weight changes
- Recent vomiting, diarrhea, fever, or infection
- Questions about food and fluid restrictions
What Questions Should You Ask Your Healthcare Team?
- What is causing my kidney-function change?
- Could any part of it be reversible?
- What are my current eGFR and UACR results?
- Are the results stable or changing?
- How often should the tests be repeated?
- What is my blood-pressure target?
- Which medicines protect my kidneys?
- When should creatinine and potassium be rechecked?
- Are my pain medicines and supplements safe?
- Should I limit sodium, protein, potassium, phosphorus, or fluids?
- Do I need a renal dietitian?
- Should I see a nephrologist?
- Which symptoms require urgent or emergency care?
Key Takeaway
How to improve kidney function safely begins with identifying the cause and measuring kidney health correctly.
Temporary kidney dysfunction may improve when dehydration, infection, obstruction, medicine effects, high blood pressure, or high blood glucose is treated.
Established chronic kidney disease usually cannot be repaired with a special food, drink, or detox. Treatment can still protect remaining function and reduce the risk of kidney failure and cardiovascular disease.
The most important daily actions include monitoring eGFR and UACR, controlling blood pressure and diabetes, taking appropriate medicines, reducing excess sodium, staying active, avoiding smoking, and reviewing kidney-risk medicines.
Protein, potassium, phosphorus, and fluid advice must be individualized.
Severe breathlessness, chest pain, confusion, seizures, collapse, dangerous palpitations, or very little urine with serious illness requires emergency care.

Frequently Asked Questions
How can you improve kidney function safely?
Identify and treat reversible causes, control blood pressure and diabetes, take appropriate kidney-protective medicines, monitor eGFR and urine albumin, follow individualized nutrition advice, stay active, avoid smoking, and review kidney-risk medicines.
Can damaged kidneys heal?
Kidney function may improve after a reversible acute problem such as dehydration, infection, obstruction, or a medicine effect is treated. Established chronic kidney scarring usually cannot be fully reversed.
Can you raise eGFR naturally?
There is no food or supplement proven to raise eGFR reliably. A result may improve when dehydration, illness, blood pressure, glucose, obstruction, or medicine effects are addressed.
What two tests are most important for kidney health?
eGFR estimates kidney filtration, while UACR measures albumin leaking into urine. Both should be interpreted with trends, the underlying cause, and other clinical information.
What foods repair the kidneys?
No individual food repairs chronically damaged kidney tissue. A balanced, individualized eating pattern may support blood pressure, blood glucose, cardiovascular health, and nutrition.
How much water should you drink for kidney function?
There is no universal amount. Fluid needs depend on urine output, swelling, heart function, sodium, medicines, dialysis, weather, activity, and fluid losses.
Does drinking more water increase eGFR?
Not necessarily. Correcting dehydration may improve an abnormal result, but excessive water does not repair chronic kidney damage and may be dangerous for some people.
Does lemon water improve kidney function?
No. Lemon water does not treat chronic kidney disease. Citrate may be used in selected kidney-stone prevention plans, but it does not dissolve every stone.
Is cranberry juice good for kidney function?
Cranberry is studied mainly for recurrent UTI prevention in selected people. It does not restore kidney filtration or treat chronic kidney disease.
Should everyone with CKD avoid bananas and potatoes?
No. Potassium restriction depends on blood-potassium results, medicines, kidney function, constipation, acidosis, and other factors.
Should protein be restricted for kidney health?
Protein needs depend on CKD stage, dialysis, age, nutrition, pregnancy, and illness. Excessive restriction may cause malnutrition and muscle loss.
Which pain medicines can harm the kidneys?
NSAIDs such as ibuprofen and naproxen may cause kidney injury, especially during dehydration, low blood pressure, infection, or use with interacting medicines.
Can exercise improve kidney function?
Exercise does not regenerate kidney tissue, but it may improve blood pressure, blood glucose, cardiovascular health, strength, sleep, and weight management.
Which medicines may protect kidney function?
Depending on the condition, treatment may include an ACE inhibitor, ARB, SGLT2 inhibitor, or another medicine for blood pressure, diabetes, albuminuria, heart failure, and cardiovascular risk.
When should you see a nephrologist?
Referral may be appropriate for advanced or rapidly worsening kidney disease, high albuminuria, resistant blood pressure, repeated high potassium, unexplained kidney dysfunction, inherited disease, or kidney-failure planning.
When is reduced kidney function an emergency?
Seek emergency help for severe breathlessness, chest pain, confusion, seizures, collapse, dangerous palpitations, or very little urine with serious illness.
