Prediabetes Specialists in Tamil Nadu

What is Prediabetes?

Prediabetes is a condition in which blood sugar levels are higher than normal but not yet high enough to be classified as type 2 diabetes, representing an important warning stage where intervention can prevent or delay disease progression. It occurs when the body's cells become resistant to insulin or the pancreas cannot produce enough insulin to keep blood sugar within a normal range. Prediabetes is often asymptomatic and is typically discovered incidentally during routine blood testing, making regular screening particularly important for those with risk factors. Without lifestyle changes, a substantial proportion of people with prediabetes go on to develop type 2 diabetes within several years. Importantly, prediabetes is considered reversible in many cases through sustained weight loss, dietary change, and increased physical activity.

Causes of Prediabetes

Caused primarily by insulin resistance, in which the body's cells respond less effectively to insulin, requiring the pancreas to produce more to maintain normal blood sugar levels until it can no longer keep pace. Risk factors include excess body weight particularly around the abdomen, physical inactivity, family history of diabetes, and a diet high in refined carbohydrates and sugar. Age over 45, polycystic ovary syndrome, and a history of gestational diabetes further increase risk.

Symptoms of Prediabetes

Often asymptomatic, occasional increased thirst, frequent urination in some cases, fatigue, darkened skin patches particularly around the neck and armpits, blurred vision in advanced cases, slow-healing cuts or wounds

Treatment & Types of Prediabetes in Tamil Nadu

The primary approach is intensive lifestyle modification, including weight loss of even five to seven percent of body weight, regular physical activity, and dietary changes emphasising whole grains, vegetables, and reduced refined carbohydrate intake. Metformin may be prescribed for individuals at particularly high risk of progression to diabetes, especially those with obesity or a history of gestational diabetes. Regular blood sugar monitoring and periodic HbA1c testing help track progress and detect progression early.

Prediabetes is classified by which blood test identifies it: impaired fasting glucose, where fasting blood sugar is mildly elevated; impaired glucose tolerance, identified through an oral glucose tolerance test showing higher-than-normal blood sugar two hours after a glucose load; and an elevated HbA1c in the prediabetic range, reflecting average blood sugar over the preceding two to three months. A person can have one, two, or all three patterns simultaneously, and the specific pattern can influence which lifestyle or medical interventions a doctor recommends.
