Unusual thirst, frequent urination and persistent tiredness can be early clues to elevated blood sugar, while blurred vision, slow-healing wounds and recurrent infections may signal a more persistent problem.
High blood sugar can creep up quietly, which is part of what makes it so easy to miss. The Indian Express article, drawing on advice from Dr Pranav Ghody, a consultant endocrinologist and diabetologist at Wockhardt Hospitals in Mumbai Central, says the earliest clues are often ordinary-seeming complaints such as unusual thirst, extra trips to the toilet and persistent tiredness. Those symptoms can have many explanations, but they are also among the common ways the body signals that glucose levels may be running too high.
Dr Ghody’s explanation is straightforward: hyperglycaemia develops when the body does not make enough insulin or when its cells stop responding properly to it. Insulin is the hormone that helps move glucose out of the bloodstream and into cells, where it is used for energy. When that process breaks down, sugar remains in the blood, and the kidneys try to clear the excess through urine. That is why thirst and urination are often early warning signs, a pattern also described by the Mayo Clinic and Cleveland Clinic in their own patient guidance on diabetes and hyperglycaemia.
Other symptoms can be less obvious but still matter. The Indian Express piece says people may notice blurred vision, dry mouth, itchy skin, a stronger hunger than usual, slow-healing wounds, recurrent urinary or fungal infections, unexplained weight loss, or tingling and numbness in the hands and feet. The Mayo Clinic likewise lists increased thirst, frequent urination, fatigue, blurred vision and weight loss among the classic signs of diabetes, while Cleveland Clinic includes slow-healing sores and numbness or tingling as symptoms that can appear when blood sugar stays elevated for too long.
Several of these warning signs are not specific to diabetes and can be caused by other conditions, including dehydration, anaemia, thyroid problems, nerve compression or infection. That makes pattern and persistence important. Sudden vision loss, worsening wounds, repeated infections or ongoing numbness should not be brushed aside, particularly if they occur alongside thirst, fatigue or frequent urination. The Mayo Clinic warns that untreated hyperglycaemia can lead to serious complications, which is why persistent symptoms warrant medical assessment rather than guesswork.
Prevention and control, according to the article, depend less on crash diets than on sustainable habits. That means eating more fibre-rich foods such as vegetables, pulses, whole grains and fruit; cutting back on sugary drinks and refined carbohydrates; staying active; taking a short walk after meals; maintaining a healthy weight; sleeping well; managing stress; and breaking up long periods of sitting. The advice reflects a broader consensus in clinical guidance: blood sugar is not managed by one dramatic change, but by a series of small, repeatable ones that support insulin sensitivity and overall metabolic health.
