How to Keep Diabetes Under Control: 12 Smart Steps

How to keep diabetes under control starts with a personal blood sugar plan, regular monitoring, taking medicine as prescribed, balanced meals, physical activity, and routine checks for the heart, kidneys, eyes, nerves, and feet. Good diabetes care also means preventing dangerous low blood sugar and knowing when very high glucose needs urgent help.

There is no single perfect glucose number, diet, medicine, or exercise plan for every person with diabetes. Your type of diabetes, age, pregnancy status, medicines, kidney function, heart health, risk of low blood sugar, and daily life all change what safe control looks like.

This article is for general information and education. It does not replace medical advice, diagnosis, or treatment.

What does keeping diabetes under control really mean?

Good diabetes care is not just about chasing one glucose reading.

The bigger goal is to keep blood glucose in a safe personal range while lowering the risk of low blood sugar, heart disease, kidney disease, eye disease, nerve damage, foot problems, and other complications.

That takes more than food.

It usually involves:

• Glucose monitoring
• Medicine or insulin when prescribed
• Meal planning
• Regular physical activity
• Blood pressure care
• Cholesterol management
• Eye checks
• Kidney checks
• Foot care
• Smoking avoidance
• Sleep and stress care

If you want a broader overview, start with the NextFitLife Diabetes and Blood Sugar Management Guide.

1. Know your personal A1C and glucose targets

A universal blood sugar goal sounds simple.

Real diabetes care is more personal.

The 2026 American Diabetes Association Standards state that an A1C below 7% is appropriate for many nonpregnant adults when that level can be reached without severe or burdensome hypoglycemia.

For many nonpregnant adults, common ADA glucose targets are:

These are common reference targets, not instructions to change medicine or insulin.

Your goal may need to be less strict if you are older, frail, prone to severe low blood sugar, living with several serious health conditions, or have other treatment risks.

Some healthy adults can safely use a lower target.

Pregnancy uses different goals.

That is why the best question is not, “What number should everyone have?”

Ask, “What target is safe for me?”

2. Use glucose readings to find patterns, not to judge yourself

A glucose meter or continuous glucose monitor gives information.

It does not give a grade.

Glucose changes with:

• Food
• Exercise
• Stress
• Sleep
• Illness
• Medicine timing
• Insulin doses
• Hormones
• Alcohol

Look for patterns instead of reacting to one isolated number.

Ask:

• Does breakfast cause a repeated rise?
• Does walking after dinner lower glucose?
• Are you going low overnight?
• Does illness push glucose higher?
• Do certain medicines cause unexpected changes?

Share those patterns with your diabetes care team.

What is time in range?

If you use CGM, time in range can add useful detail that A1C cannot show.

The 2026 ADA Standards use 70 to 180 mg/dL as the usual CGM target range for many nonpregnant adults and suggest spending more than 70% of the day in that range when appropriate.

Time below range matters too.

A good A1C is not good control if it is achieved through repeated dangerous lows.

3. Treat low blood sugar quickly

A glucose level below 70 mg/dL is considered low.

Hypoglycemia can cause:

• Shaking
• Sweating
• Hunger
• Fast heartbeat
• Dizziness
• Weakness
• Irritability
• Confusion

Some people lose the normal warning signs of low glucose.

That makes prevention even more important.

The 15 minute approach

For many adults who are awake and able to swallow safely, CDC guidance uses this simple approach:

1. Take 15 grams of fast acting carbohydrate.
2. Wait 15 minutes.
3. Check glucose again.
4. If it remains below 70 mg/dL, repeat the treatment.

Examples of fast acting carbohydrate include glucose tablets, glucose gel, regular soda, or juice in an appropriate amount.

Chocolate is not ideal for fast treatment because fat can slow sugar absorption.

When low blood sugar becomes an emergency

A person who is unconscious, having a seizure, severely confused, or unable to swallow safely should not be given food or drink by mouth.

Use prescribed glucagon if available and seek emergency medical help.

Current ADA guidance recommends glucagon for people treated with insulin and others at high risk for severe hypoglycemia.

4. Know when high blood sugar needs urgent action

Hyperglycemia is not simply the opposite of a low.

One high reading may happen after food, illness, stress, or missed medicine.

A repeated high pattern needs review.

Very high glucose with ketones can become dangerous.

Watch for diabetic ketoacidosis

Diabetic ketoacidosis, or DKA, happens when the body does not have enough effective insulin.

It is most common in type 1 diabetes but can also occur in type 2 diabetes.

Warning signs can include:

• Very high glucose
• High ketones
• Strong thirst
• Frequent urination
• Nausea
• Vomiting
• Abdominal pain
• Deep or difficult breathing
• Fruity smelling breath
• Severe tiredness
• Confusion

CDC advises people with diabetes who are sick or whose glucose is very high to follow their ketone and sick day plan.

High ketones or several DKA symptoms need urgent medical care.

Do not try to correct dangerous high glucose with a random extra insulin dose found online.

Use the correction plan given by your diabetes team.

5. Build meals around balance, not fear of carbohydrates

Carbohydrates raise blood glucose.

That does not mean a person with diabetes must remove all carbohydrates.

The amount, type, timing, medicine, insulin, activity, and personal response all matter.

The CDC plate method is a useful starting point:

Choose water or another unsweetened drink when possible.

Whole foods with fiber usually make glucose easier to manage than large portions of refined carbohydrate or sugary drinks.

Carbohydrate counting is useful for some people

Carbohydrate counting can be especially important if you use mealtime insulin.

Your insulin dose may need to match the amount of carbohydrate you plan to eat.

That is a skill worth learning from a diabetes educator or dietitian rather than guessing.

There is no universal carbohydrate limit that works for every person with diabetes.

6. Move your body most days

Exercise helps muscle use glucose and improves insulin sensitivity.

CDC recommends aiming for at least 150 minutes of moderate intensity activity each week for most adults.

The 2026 ADA Standards also encourage most adults with diabetes to reach at least 150 minutes of moderate to vigorous aerobic activity each week, spread across several days.

Resistance training matters too.

ADA recommends two or three resistance exercise sessions per week for many adults with diabetes.

Useful choices include:

• Walking
• Cycling
• Swimming
• Resistance bands
• Weights
• Bodyweight strength work

Start below the full target if you are inactive.

A short walk is better than waiting for the perfect one hour workout.

Exercise can also cause low glucose

People who take insulin or some glucose lowering medicines may develop low blood sugar during or after exercise.

You may need a personal plan for:

• When to check glucose
• What carbohydrate to carry
• When to delay exercise
• Medicine adjustments
• Insulin adjustments

Do not change insulin doses on your own.

7. Take diabetes medicine as prescribed

A healthy lifestyle does not make diabetes medicine a failure.

Medicine is part of treatment when your body needs it.

Depending on the type of diabetes and your health, treatment may include:

• Insulin
• Metformin
• GLP 1 receptor agonists
• SGLT2 inhibitors
• DPP 4 inhibitors
• Sulfonylureas
• Other medicines

The right medicine depends on much more than glucose.

Your care team may also consider:

• Heart disease
• Heart failure
• Kidney disease
• Body weight
• Low blood sugar risk
• Side effects
• Cost
• Pregnancy plans
• Your preferences

Do not stop insulin or another prescribed diabetes medicine because your readings look better for several days.

8. Diabetes treatment now protects more than blood sugar

This is one of the biggest changes from older diabetes advice.

Some newer medicines are selected partly because they protect the heart and kidneys.

The 2026 ADA Standards recommend an SGLT2 inhibitor or GLP 1 receptor agonist with proven cardiovascular benefit for many people with type 2 diabetes who have established cardiovascular disease, chronic kidney disease, or certain high risk patterns.

These medicines are not right for everyone.

They also have different side effects, precautions, costs, and treatment rules.

The point is simple:

Modern diabetes treatment is no longer just about lowering an A1C number.

Read more in Diabetes and Heart Diseases: Risks, Prevention, and Care.

9. Protect your kidneys

Diabetic kidney disease can develop before obvious symptoms appear.

That is why regular testing matters.

Kidney checks usually include:

• A blood test that estimates kidney filtering function
• A urine test for albumin

NIDDK recommends annual kidney testing for people with type 2 diabetes and for people who have had type 1 diabetes for more than five years.

Your clinician may test more often if kidney disease is already present.

Blood pressure also matters.

The 2026 ADA Standards recommend individualized blood pressure goals. If it can be achieved safely, a treatment goal below 130/80 mmHg is recommended for many people with diabetes and hypertension.

People with kidney disease need personal advice about protein, sodium, potassium, phosphorus, and fluids.

See the NextFitLife Kidney Disease Diet Guide if kidney disease is also part of your care plan.

10. Protect your eyes, nerves, and feet

Diabetes can damage small blood vessels and nerves even when you feel well.

Eyes

Regular dilated eye exams help find diabetic retinopathy before vision loss becomes obvious.

Keep your glucose, blood pressure, and cholesterol near your personal targets.

Feet

Diabetic neuropathy can reduce feeling in the feet.

A small cut or blister can become serious when you do not feel it.

Check your feet regularly for:

• Cuts
• Blisters
• Redness
• Swelling
• Warmth
• Drainage
• Color change
• New sores

Do not wait for a routine appointment if you notice an infected wound, spreading redness, black skin, severe swelling, or a foot ulcer that is getting worse.

11. Do not ignore blood pressure, cholesterol, or smoking

Diabetes raises cardiovascular risk.

Glucose is only one part of that risk.

Good long term care also includes:

• Blood pressure control
• Cholesterol treatment when needed
• Smoking cessation
• Physical activity
• Heart healthy food
• Kidney protection

Stopping smoking is one of the strongest steps you can take to protect your heart, blood vessels, kidneys, and feet.

12. Make sleep, stress, and support part of the plan

Diabetes management can become tiring.

That matters.

Poor sleep, stress, depression, medication fatigue, food costs, work schedules, and fear of low blood sugar can all make self care harder.

A plan that looks perfect on paper but cannot fit your life is not a good plan.

Talk with your care team about:

• Sleep problems
• Stress
• Depression
• Cost of medicine
• Fear of insulin
• Food access
• Work schedules
• Difficulty using glucose technology

Diabetes self management education can help with food, medicines, glucose monitoring, exercise, sick day care, and problem solving.

How often should A1C be checked?

A1C reflects average glucose over roughly two to three months.

The 2026 ADA Standards advise assessing glycemic status at least twice each year for people who are meeting their goals and have stable treatment.

Testing is often done around every three months when:

• Targets are not being met
• Treatment has changed
• Low or high glucose is frequent
• Health status has changed

Your care team can set the schedule that fits your situation.

What should you do on sick days?

Illness often raises blood glucose.

Vomiting or poor food intake can also increase the risk of dehydration and low glucose, depending on your medicines.

Your diabetes team should give you a sick day plan.

That plan may cover:

• How often to check glucose
• When to check ketones
• Which medicines to continue
• Which medicines may need to be held
• How to stay hydrated
• When to call the clinic
• When to seek emergency care

Do not create your own medicine stopping rules from a general internet article.

Some diabetes medicines need special instructions during vomiting, fasting, dehydration, surgery, or severe illness.

What should you do if your glucose is repeatedly high?

Do not panic over one result.

Look for a pattern.

Check whether:

• A dose was missed
• You are ill
• The meal contained more carbohydrate than usual
• Stress is high
• You have been much less active
• Your insulin or medicine schedule has changed

Follow the correction plan provided by your diabetes team.

If high glucose keeps happening, contact them.

A repeated high pattern usually means the plan needs review, not that you need to punish yourself with fasting or extreme exercise.

Do you need to stop eating sugar forever?

No single food decides whether diabetes is controlled.

Food patterns matter more.

A person with diabetes can usually eat carbohydrate foods, including fruit and grains, within an appropriate meal plan.

The bigger problems are often large portions, sugary drinks, highly refined foods, and meals that contain far more carbohydrate than the person's medicine or insulin plan can cover.

Use the plate method, learn your carbohydrate response, and work with a diabetes trained dietitian when you need more structure.

Does drinking more water lower blood sugar?

Water is a good main drink and helps prevent dehydration.

It does not replace insulin or medicine.

It also does not safely correct severe hyperglycemia.

If high glucose is linked with ketones, vomiting, dehydration, or DKA symptoms, drinking water at home is not enough.

Does walking after meals help?

Physical activity can lower glucose because working muscles use glucose.

Walking after a meal is a simple way to add activity and may help reduce post meal glucose for some people.

If you take insulin or medicine that can cause low glucose, learn how activity affects you before making long walks a fixed part of your plan.

Can type 2 diabetes go into remission?

Some people with type 2 diabetes can reach remission, especially after substantial sustained weight loss or metabolic surgery.

Remission is not the same as a guaranteed permanent cure.

Glucose can rise again.

People in remission still need follow up and ongoing attention to cardiovascular and metabolic health.

Type 1 diabetes does not go into remission through diet or exercise and requires insulin treatment.

A simple diabetes care checklist

When should you contact your diabetes team sooner?

Do not wait for the next routine appointment if you have:

• Repeated low blood sugar
• A severe low that needed another person's help
• Repeated very high glucose
• High ketones
• Vomiting or dehydration
• New foot sores
• New vision changes
• Rapid unexplained weight loss
• New numbness or burning pain
• Medicine side effects
• Difficulty paying for medicine or testing supplies
• A pregnancy or plans for pregnancy

A treatment plan should change when your health changes.

Conclusion

Learning how to keep diabetes under control is not about chasing perfect numbers every hour. It is about building a safe plan that keeps glucose near your personal targets while protecting your heart, kidneys, eyes, nerves, and feet.

Start with one useful next step today: review your latest A1C and glucose pattern, confirm your personal targets, and ask your diabetes care team what one change would make your plan safer or easier to follow.

Frequently Asked Questions

What is the best way to keep diabetes under control?

The best approach combines personal glucose targets, regular monitoring, medicine or insulin as prescribed, balanced meals, physical activity, and routine checks for blood pressure, cholesterol, kidneys, eyes, nerves, and feet. The plan should be adjusted to your type of diabetes and health needs.

What A1C is considered good for diabetes?

An A1C below 7% is appropriate for many nonpregnant adults, according to the 2026 ADA Standards, but the target must be individualized. Older age, pregnancy, severe low blood sugar, kidney disease, frailty, and other health factors can change the safest goal.

What blood sugar level should a person with diabetes aim for?

For many nonpregnant adults, common ADA targets are 80 to 130 mg/dL before meals and below 180 mg/dL after meals. These are general reference targets, not personal instructions, so ask your healthcare team which range applies to you.

What is time in range?

Time in range is the percentage of CGM readings between 70 and 180 mg/dL. For many nonpregnant adults using continuous glucose monitoring, the ADA uses a goal above 70%, while also limiting time spent below 70 mg/dL.

What should I do if my blood sugar is below 70?

If you are awake and able to swallow safely, CDC guidance commonly uses 15 grams of fast acting carbohydrate followed by a glucose check after 15 minutes. Repeat if the level remains below 70 mg/dL. Severe low blood sugar may require glucagon and emergency help.

What foods help keep diabetes under control?

There is no single diabetes food. A practical meal pattern includes plenty of nonstarchy vegetables, suitable portions of high fiber carbohydrate foods, protein, healthy fats, and fewer sugary drinks and highly refined foods.

Do people with diabetes need to avoid carbohydrates?

No. Carbohydrates affect blood glucose, but they do not have to be removed completely. Portion size, food quality, timing, insulin, medicine, activity, and the person's own glucose response all matter.

How much exercise is recommended for diabetes?

Most adults with diabetes are encouraged to work toward at least 150 minutes of moderate to vigorous aerobic activity each week. The 2026 ADA Standards also recommend two or three resistance exercise sessions per week for many adults.

Can exercise cause low blood sugar?

Yes. Exercise can lower glucose during and after activity, especially in people using insulin or medicines that increase low blood sugar risk. A personal exercise plan may include glucose checks, carbohydrate, and medicine or insulin instructions.

Can diabetes medicine protect the heart and kidneys?

Yes. Certain SGLT2 inhibitors and GLP 1 receptor agonists have demonstrated cardiovascular or kidney benefits in selected people with type 2 diabetes. Medicine choice should be made with a healthcare professional because benefits, side effects, kidney function, cost, and other factors matter.

How often should A1C be checked?

People with stable diabetes who are meeting their goals may only need A1C assessment about twice each year. Testing is often done around every three months when treatment changes, goals are not being met, or glucose is less stable.

What should I do if my blood sugar stays high?

Follow your prescribed correction and sick day plan, look for patterns, and contact your diabetes team if high readings continue. High glucose with ketones, vomiting, severe dehydration, breathing difficulty, or other DKA symptoms needs urgent medical care.

Should people with diabetes check their feet every day?

Regular foot checks are especially important when there is neuropathy or poor circulation. Look for cuts, sores, redness, swelling, blisters, warmth, drainage, or color changes and report concerning wounds promptly.

Can type 2 diabetes go into remission?

Yes, some people with type 2 diabetes can reach remission, especially after substantial sustained weight loss or metabolic surgery. Remission is not the same as a permanent cure, and ongoing follow-up is still needed.

When is diabetes an emergency?

Severe low blood sugar, loss of consciousness, seizures, severe confusion, high ketones, repeated vomiting, severe dehydration, deep or difficult breathing, or several signs of diabetic ketoacidosis can require emergency medical care.
