Early Warning Signs of Diabetes

Type 2 diabetes rarely announces itself loudly. In my practice in Bhopal, many patients discover they have diabetes only during a routine checkup or when a blood test is done for some other reason. By then, the sugar may have been elevated for years. The good news is that the body usually gives early signals — if we know what to look for.

Common early symptoms

• Frequent urination, especially waking up at night to pass urine
• Persistent thirst and a dry mouth despite drinking water
• Unexplained tiredness or low energy through the day
• Increased hunger, even after meals
• Blurred vision that comes and goes
• Slow-healing cuts, frequent skin or urinary infections
• Tingling or numbness in the feet

Who should get tested even without symptoms?

You should consider a blood sugar test if you are over 30–35 years of age, have a family history of diabetes, are overweight (especially around the abdomen), have had diabetes during pregnancy, or have conditions like fatty liver, high blood pressure or high cholesterol. In India, diabetes tends to appear earlier and at lower body weights than in Western populations, so waiting for symptoms is not a safe strategy.

Which tests are used?

A fasting blood sugar, post-meal blood sugar and HbA1c (which reflects average sugar over about three months) are the standard tests. These are simple, widely available and inexpensive. Your physician interprets them together — a single borderline reading does not always mean diabetes, and a normal reading does not always rule it out.

What to do if your sugar is borderline

A 'pre-diabetes' result is an opportunity, not a verdict. Structured changes in diet, regular physical activity, weight management and good sleep can significantly delay or even prevent progression. This is best done under medical guidance rather than through crash diets or unverified remedies.

If you recognise any of these symptoms — or fall in a higher-risk group — a consultation and a simple blood test are a sensible next step. Early evaluation makes management far easier.
