Blood sugar plays a central role in your overall health, yet most people rarely think about it until symptoms begin. Across India, the number of adults with prediabetes and diabetes has increased rapidly due to lifestyle changes, stress, irregular meal timings and reduced physical activity. According to recent health surveys, more than 100 million Indians are diabetic and nearly 136 million are prediabetic, and many do not even know it.
This lack of awareness is one of the biggest reasons diabetes is often diagnosed late, when complications such as nerve damage, kidney problems and vision issues have already started. But the good news is that diabetes is one of the most preventable lifestyle conditions, and early detection makes a dramatic difference.
Understanding what your sugar levels mean, getting screened at the right time and knowing the early warning signs can protect your long term health. This blog simplifies normal sugar ranges and explains why timely testing is important.
What Is Blood Sugar and Why Does It Matter
Blood sugar or glucose is the body’s main fuel. Every cell depends on it for energy. Insulin, produced by the pancreas, helps move this sugar from the bloodstream into cells. When the body stops responding properly to insulin or does not produce enough, blood sugar levels rise.
This imbalance leads to:
- Prediabetes – a stage where sugar is moderately high
- Diabetes – when sugar levels remain consistently high
- Risk of complications – if unmanaged over time
Knowing your sugar range early helps you take corrective action before the condition becomes serious.
Normal Blood Sugar Levels (Explained Clearly)
Your doctor usually recommends three key tests. Here is what each one means, including the ranges commonly used in diagnosis.
1. Fasting Blood Sugar (FBS)
This test measures sugar after 8 to 10 hours of fasting.
- Normal: 70 to 99 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or above
If your fasting sugar falls repeatedly above 100, it indicates early insulin resistance.
2. Post Meal Blood Sugar (PPBS)
Taken two hours after eating.
- Normal: Less than 140 mg/dL
- Prediabetes: 140 to 199 mg/dL
- Diabetes: 200 mg/dL or above
Higher post meal readings often appear before fasting levels start rising.
3. HbA1c Test
This test shows your average blood sugar levels of the last three months.
- Normal: Below 5.7 percent
- Prediabetes: 5.7 to 6.4 percent
- Diabetes: 6.5 percent or above
HbA1c is one of the best tests to identify long term sugar imbalance.
Are You in the Prediabetic Stage Without Knowing It
One of the biggest reasons diabetes spreads silently is that early signs are mild or ignored. Many people feel completely normal even when sugar levels are rising.
Common warning signs include:
- Feeling unusually tired
- Increased thirst
- Frequent urination
- Sudden hunger or cravings
- Unexplained weight gain
- Darkening of skin around the neck or underarms
- Slow healing of cuts
- Blurred vision
- A strong family history of diabetes
Women with PCOS are also at higher risk.
Why Early Detection Matters More Than Ever
Recent studies show that nearly half of Indians with diabetes are diagnosed late. Many patients live with elevated sugar for years without knowing it. This delayed diagnosis increases the risk of:
- Kidney disease
- Nerve damage
- Foot ulcers
- Heart attacks
- Stroke
- Vision loss
- Frequent infections
Early detection, especially at the prediabetes stage, can dramatically reduce the risk of these complications. Lifestyle changes made at the right time can reverse prediabetes and prevent progression to diabetes.
Who should get screened?
- Adults above 30
- Anyone overweight
- People with a family history of diabetes
- Women with PCOS
- Individuals with high blood pressure or high cholesterol
- Anyone with symptoms like frequent urination or unexplained fatigue
Daily Habits to Maintain Healthy Blood Sugar Levels
Healthy sugar levels depend heavily on daily routines. Small changes add up over time.
Useful habits include:
- Eating balanced meals with more fibre and protein
- Avoiding excess sugar or refined carbohydrates
- Walking 30 minutes a day
- Getting 6 to 8 hours of sleep
- Managing stress
- Avoiding frequent snacking
- Staying hydrated
Seasonal factors
- Winter: Higher cravings can raise sugar levels
- Monsoon: Infections can temporarily increase blood sugar
- Summer: Dehydration may cause fluctuations
Being aware of these seasonal patterns helps you stay in control.
When You Should Consult a Doctor
Seek medical care if you notice:
- Repeated high fasting readings
- Post meal readings crossing 160 regularly
- Burning sensation in feet
- Sudden weight changes
- Persistent infections or slow healing wounds
- Excessive thirst or urine output
Your doctor may recommend detailed tests, dietary guidance and professional monitoring.
