Unveiling the Hidden Danger: Understanding 'Pre-Pre-Diabetes' and Metabolic Dysfunction
Are you at risk of diabetes even if your blood sugar levels are normal?
For years, we've believed that normal blood sugar levels are a safe haven from diabetes. But a surprising revelation from clinical practice challenges this notion. An increasing number of individuals with seemingly perfect blood sugar readings are actually at high risk. This early stage, informally termed 'pre-pre-diabetes', is where metabolic dysfunction begins, long before any noticeable rise in glucose levels. While the body may appear to be functioning normally, insulin pathways are already struggling, setting the stage for potential health issues.
Dr. Saptarshi Bhattacharya, a senior consultant in endocrinology at Indraprastha Apollo Hospitals, sheds light on this crucial topic. He explains that prediabetes is a warning sign, a sign that the pancreas is working overtime. Your glucose levels may seem normal, but this is because your body is secreting extra insulin to compensate. However, this struggle often goes undetected in routine tests, leading many to believe they are in the clear. During this phase, fasting insulin levels rise, visceral fat accumulates, triglycerides may spike, and inflammation starts to simmer, all while glucose readings remain within normal limits.
The outward picture may look normal, but metabolically, the body is already under stress. This mismatch of normal blood glucose and underlying dysfunction is driven by various factors, including genetics, high-carb diets, sedentary lifestyles, physical inactivity, and poor sleep. A person can have good HbA1c levels but still carry significant internal risk. Many individuals with normal glucose profiles struggle with fatigue, post-meal sleepiness, sugar cravings, belly fat, frequent mood dips, skin darkening around the neck (acanthosis nigricans), or difficulty losing weight.
These symptoms are often dismissed as routine tiredness or lifestyle issues, but they can be early signs of insulin resistance. Insulin resistance is now recognized as the fundamental driver behind metabolic syndrome, PCOS, fatty liver, prediabetes, and eventually Type 2 diabetes. When insulin levels remain high for years, cells stop responding, and the pancreas compensates by releasing even more insulin. This silent cycle continues, and by the time blood glucose levels start rising, the process has already been ongoing for eight to ten years.
This is why young Indians in their twenties and thirties, with a normal BMI, are increasingly being diagnosed with fatty liver and metabolic syndrome. Doctors now recommend a deeper look for anyone with a family history of diabetes, weight issues, PCOS, thyroid concerns, sedentary jobs, or chronic stress. Glucose parameters in prediabetes, minor changes in lipid profile, elevated liver enzymes, high-sensitivity CRP, and fatty liver on ultrasound should not be ignored and may reflect early signs of internal metabolic derangement. Even simple measures like waist circumference, waist-to-height ratio, or a body composition scan can uncover high visceral fat behind an outwardly slim frame.
Testing glucose levels alone may not provide the full picture. However, assessing insulin and inflammation early can help prevent diabetes before it begins. The good news is that pre-diabetes is reversible with consistent lifestyle changes. Prioritizing protein in every meal, increasing greens and fiber, reducing refined carbs and packaged foods, and choosing millets, dals, nuts, and healthier fats can help stabilize insulin. Strength training, often overlooked, is crucial as muscle tissue is the biggest user of glucose, and building muscle mass can greatly improve insulin sensitivity. Regular movement, such as a short 10–15-minute walk after meals, can also reduce glucose spikes and insulin demand. Better sleep, stress control techniques, hydration, and reducing late-night eating further strengthen metabolic resilience.
In a country with rising lifestyle diseases, understanding this early, hidden phase may be one of the most powerful tools in changing long-term health outcomes. So, are you at risk? It's time to listen to your body's warning signs and take action before it's too late.
