Gastro doctor, Dr Pal warns: 5 signs your blood sugar is out of control — even if your reports look 'normal'

You might think your blood sugar is under control because your reports say so — but your body may be telling a different story. Gastroenterologist Dr Pal warns that even when test results appear “normal,” early signs of blood sugar imbalance can quietly show up in your energy, focus, and skin. Ignoring them could push you closer to insulin resistance or even diabetes before you realise it.

Here are the five red flags to watch out for, according to Dr Pal.

Constant fatigue

If you sleep well but still wake up tired, it’s not just stress or age catching up. Fluctuating blood sugar levels silently drain your energy and make your cells resistant to insulin, leaving you exhausted even after a full night’s rest.

Craving sweets after meals

That irresistible urge for dessert right after lunch or dinner isn’t harmless. It’s your body’s way of signalling that it’s struggling to regulate post-meal sugar spikes.

Brain fog and poor focus

If you feel mentally dull or forgetful more often, unstable sugar levels could be disturbing your brain’s glucose supply. This foggy feeling is one of the lesser-known early signs of poor metabolic health.

Night-time urination or restless sleep

Frequent urination, excessive thirst, or waking up multiple times during the night can mean your body is trying to flush out excess glucose. Over time, this can affect sleep quality and recovery.


Slow wound healing or skin issues

Cuts that take too long to heal, dark patches around the neck or underarms, or recurring fungal infections are clear indicators of insulin resistance taking hold.

Dr Pal warns that you don’t need to wait for your HbA1c to cross 7 to take action. These subtle signs mean your metabolism needs a reset before diabetes takes control.

How to manage diabetes?

ABCS
According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), managing diabetes comes down to understanding your ABCs — A for A1C, B for blood pressure, C for cholesterol, and S for stopping smoking. Keeping these in check can lower your chances of serious health issues like heart attack, stroke, or kidney disease.

A1C test
The A1C test reflects your average blood glucose over three months. Most people aim for below 7%, but goals can differ depending on individual health conditions. Always check with your doctor about your ideal range.

Blood Pressure
Your blood pressure is equally important. High readings can damage your heart, brain, and kidneys.

Cholesterol levels
When it comes to cholesterol, maintaining healthy levels prevents clogged arteries and reduces the risk of heart attack or stroke. Some people may need statins or other medication to keep cholesterol in check.

Smoking
Lastly, stop smoking — or vaping. Both restrict blood vessels, and when paired with diabetes, the risks multiply.

Balanced meal plan

A healthy lifestyle can help you regain control. Build a balanced meal plan that includes your favourite foods in moderation. Get at least 150 minutes of moderate activity a week, such as brisk walking, and try adding two days of strength training. If you’re overweight, your doctor can help with personalised strategies to manage weight safely.

Sleep Stress
Don’t forget sleep and stress — both directly affect blood sugar. Aim for 7 to 8 hours of rest each night and find healthy ways to manage tension through mindfulness or physical activity.

Even if your reports look fine, your body might already be raising quiet alarms. Paying attention now could save you from much bigger health battles later.
