Prediabetes early signs HbA1c levels and prevention at Westin Hospitals

Published: 15 September 2026

Quick Answer: Prediabetes means your blood sugar is higher than normal but has not yet reached the diabetes range. In many people, it causes no obvious symptoms. Blood sugar testing is especially important if you have risk factors such as excess weight, family history of diabetes, PCOS, high blood pressure or low physical activity.

Early detection of prediabetes is essential in preventing type 2 diabetes because a patient can make specific lifestyle changes to reduce the risk.

At Westin Hospitals, Madhapur, patients with high blood sugar or suspected prediabetes can consult the Endocrinology Department or General Medicine Department for evaluation.

What Is Prediabetes?

Prediabetes occurs when the body begins to have trouble regulating blood glucose.

One of the reasons for prediabetes is insulin resistance.

Insulin resistance is when the body's cells do not respond to insulin, which causes high levels of glucose to stay in the bloodstream.

Having prediabetes does not necessarily indicate that a person will develop diabetes, but it does increase the risk of developing it.

What Are the Early Signs of Prediabetes?

Prediabetes Often Has No Symptoms

This is the most important point.

Many people with prediabetes feel completely normal and discover it only during a routine blood test. Regular screening is therefore more reliable than waiting for symptoms.

If blood sugar levels rise further, some people may notice symptoms associated with high blood glucose.

Increased Thirst and Frequent Urination

Needing to drink water more often or urinating more frequently can occur when blood glucose becomes elevated.

If these symptoms continue, a blood sugar test may be appropriate.

Persistent Tiredness

Feeling unusually tired even after adequate sleep can have many causes.

Blood sugar problems are one possible reason, particularly when fatigue occurs together with thirst, frequent urination, weight changes or other risk factors.

Blurred Vision

Changes in blood glucose can temporarily affect the way the eyes focus.

Recurring blurred vision should not automatically be assumed to be caused by prediabetes, but it deserves medical evaluation if it persists.

Dark Skin Patches

Dark, thick or velvety skin around the neck, armpits or other body folds can be a sign of insulin resistance.

This condition is called acanthosis nigricans and may occur in people with prediabetes or type 2 diabetes.

Increased Hunger

Some people may feel hungry again soon after eating.

However, hunger alone is not enough to diagnose prediabetes and should be considered together with other symptoms and risk factors.

Who Is at Higher Risk of Prediabetes?

Your risk may be higher if you have:

  • Excess weight, especially around the waist
  • A family member with diabetes
  • Low levels of physical activity
  • High blood pressure
  • Abnormal cholesterol or triglyceride levels in the blood
  • Having had gestational diabetes during pregnancy
  • Polycystic ovary syndrome
  • Dark patches of skin, which may be a sign of insulin resistance

Prediabetes is often linked to metabolic risk factors such as obesity, high triglycerides, low levels of HDL cholesterol and high blood pressure.

What Is the HbA1c Range for Prediabetes?

The HbA1c test estimates your average blood glucose over roughly the previous two to three months.

Commonly used ranges are:

TestPrediabetes Range
HbA1c5.7%–6.4%
Fasting blood glucose100–125 mg/dL
2-hour OGTT140–199 mg/dL

These tests should be interpreted by a doctor in the context of your overall health and medical history.

Which Tests Are Used to Check for Prediabetes?

HbA1c Test

HbA1c provides an estimate of average blood glucose over the previous few months.

Fasting Blood Sugar Test

This test measures blood glucose after fasting, usually overnight.

Oral Glucose Tolerance Test

This test measures how the body handles glucose over a set period after drinking a glucose solution.

Your doctor will decide which test is most appropriate.

Westin Hospitals' Health Packages include fasting and post-lunch blood sugar testing along with physician consultation as part of the Master Health Checkup.

Can Prediabetes Be Reversed?

Prediabetes can often improve significantly with early and consistent lifestyle changes.

Helpful steps may include:

Eat More Balanced Meals

Choose more vegetables, whole grains, pulses, lean protein and high-fibre foods while reducing excess refined carbohydrates, sugary drinks and highly processed foods.

Patients who need personalised dietary guidance can consult Dietetics at Westin Hospitals.

Increase Physical Activity

Regular exercise can improve insulin sensitivity and help the body use glucose more effectively.

Work Toward a Healthy Weight

For people who are overweight, even modest weight reduction can meaningfully reduce the risk of progressing to type 2 diabetes.

Sleep Well and Manage Stress

Poor sleep and long-term stress can make healthy blood sugar management more difficult.

Attend Regular Follow-Up

Repeat blood tests may be recommended to monitor whether blood sugar is improving, remaining stable or moving toward diabetes.

Does Everyone With Prediabetes Need Medicine?

No.

Many people are able to control prediabetes with exercise and diet changes.

For some patients with a high risk of progressing to diabetes, diabetes drugs may be an option.

The choice of medicine is based on your lab results, weight, age, medical history and other factors.

Don't start taking diabetes medications on your own.

When Should You See a Doctor?

Consider medical evaluation if:

  • A routine test shows high blood sugar
  • Your HbA1c is in the prediabetes range
  • You have a strong family history of diabetes
  • You have PCOS or previous gestational diabetes
  • You have dark skin patches associated with insulin resistance
  • You frequently experience excessive thirst or urination
  • You have unexplained weight changes
  • You have several metabolic risk factors

People with prediabetes should also have cardiovascular risk factors such as blood pressure and cholesterol reviewed.

Frequently Asked Questions

Can you have prediabetes without symptoms?

Yes. Prediabetes often causes no noticeable symptoms, which is why blood testing is important for people with risk factors.

What HbA1c level means prediabetes?

An HbA1c level between 5.7% and 6.4% is commonly classified as prediabetes.

Does prediabetes always turn into diabetes?

No. Prediabetes increases the risk of type 2 diabetes, but progression is not inevitable. Early lifestyle changes and regular monitoring can reduce the risk.

Can prediabetes cause dark skin around the neck?

Dark, velvety skin around the neck or armpits may indicate insulin resistance, which is associated with prediabetes.

Which doctor should I consult for prediabetes?

A general physician can perform the initial evaluation and blood tests. An endocrinologist may be appropriate when blood glucose remains abnormal, multiple metabolic risk factors are present or specialist diabetes care is needed.

How often should prediabetes be checked?

The frequency depends on your test results and overall risk. Your doctor may recommend regular blood sugar or HbA1c monitoring based on your individual condition.
