Have you ever been told that your reports are “normal” even though you struggle every day with symptoms such as fatigue, anxiety, weight gain, brain fog, poor sleep, and digestive issues like acidity and bloating? Do unexplained aches and pains leave you feeling dismissed when you’re told they are “all in your head”, even by medical professionals? Or have you been advised to simply “relax” or “meditate” when seeking answers for persistent, unexplained symptoms? In an interview with HT Lifestyle, Smita Krishna, functional Nutritionist and holistic health coach, decodes the reason behind this unexplained illness.

Why do you still feel unwell when your blood tests are normal?
Smita highlighted that the truth is that "normal" and “optimal” are two very different things. Most laboratory ranges today are designed to identify diseases and not measure optimal health. “A marker can fall under the normal category but be less than ideal or even insufficient for the body to function in the best way,” said Smita. This is especially true for markers related to blood sugar regulation, thyroid function, vitamin D, vitamin B12, iron status, inflammation, and metabolic health.
For instance, a person can have fasting glucose levels or even an HbA1c marker within the “normal” range but may already be experiencing insulin resistance. “The normal range of TSH levels is 0.4 - 5 mIU/L; however, in my functional nutrition practice, I keep the optimum level of 2mIU/L in mind. Any higher than that, I put it under a point of concern and work on getting it to the optimal level,” said Smita.

A blood test is just a snapshot of health
According to Smita, another important factor is that blood tests provide a snapshot in time. They show what is happening biochemically but do not always reveal the underlying lifestyle factors driving symptoms. Chronic stress, poor sleep, inadequate protein intake, nutrient deficiencies, sedentary habits, gut imbalances, and hormonal fluctuations can significantly affect how you feel long before they appear as a diagnosable condition.
The blood test report is only a part of the story, valuable but incomplete. Rather than treating a disease, we ask why the body is struggling. When we deep dive and connect patterns and symptoms with blood work, we often find subclinical concern points or an infection, poor gut health, sleep issues, even if the lab ranges are fine.
Your symptoms are not all in your head. They are valuable feedback that your body is sending. Persistent fatigue, cravings, bloating, mood changes, poor recovery, and weight-loss resistance often indicate that something needs support, even if standard blood test ranges mark it as normal.
