Diabetes: Symptoms, Causes and How It Is Managed
In diabetes the body cannot use blood sugar properly. Here are the types, the early symptoms, the tests and their ranges, and the everyday habits that genuinely help keep sugar in range.
Part of what we eat reaches the blood as glucose. A hormone called insulin moves that glucose into cells. In diabetes this arrangement breaks down — either insulin is not made, or the body stops responding to it properly.
Sugar then builds up in the blood. Left that way for years it can affect the eyes, kidneys, nerves and heart. The useful part is that when it is caught early, it can largely be managed.
The types
- Type 1 — the body all but stops producing insulin. It usually appears younger, and insulin is essential.
- Type 2 — insulin is produced, but the body cannot use it well. Most cases in India are of this kind.
- Gestational diabetes — raised sugar during pregnancy. It usually settles after delivery, but it warrants follow-up.
- Prediabetes — sugar above normal but not yet in the diabetes range. This is the warning period, and the best opening to act.
Symptoms
Type 2 starts slowly. Many people feel nothing in particular for years and find out during an unrelated test. When symptoms do appear, they tend to be:
- Passing urine often, especially at night
- More thirst than usual
- Strong hunger alongside unexplained weight loss
- Persistent tiredness
- Blurred vision
- Cuts and wounds healing slowly
- Tingling or numbness in the hands and feet
- Repeated skin itching or infections
No single one of these proves diabetes. The right move is a test, not a guess.
Why it happens
- Diabetes in the family
- Excess weight, particularly around the abdomen
- A largely seated day
- A diet heavy in refined flour, sugar and fried food
- Ongoing short or poor sleep
- Sustained stress
- PCOS in women
- Increasing age
In Indian populations diabetes often appears younger and at lower body weight, so “I am not overweight” is not a reason to skip a test.
Tests and ranges
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting blood sugar | Up to 99 mg/dL | 100–125 mg/dL | 126 mg/dL or above |
| 2 hours after food | Up to 139 mg/dL | 140–199 mg/dL | 200 mg/dL or above |
| HbA1c | Up to 5.6% | 5.7–6.4% | 6.5% or above |
One report does not settle it. Doctors usually repeat the test and read it alongside symptoms, and laboratory ranges vary slightly.
Check your BMI — weight pulls directly on blood sugar→What to change on the plate
- Cut refined flour and sugar — sweetened drinks first
- Keep vegetables, dal and curd alongside the roti so the plate stays balanced
- Choose whole grains — bajra, jowar, ragi, dalia
- Include some protein at every meal — dal, chana, paneer, egg
- Eat salad and vegetables first, rice and roti after
- Eat fruit as fruit, not as juice
- A ten-minute walk after meals is a small habit that helps
No single food “fixes” blood sugar. The benefit comes from the overall shape of the diet, not from one herb or remedy.
Daily habits that make a difference
- Thirty minutes of brisk walking on most days
- Breaking up long stretches of sitting — stand up each hour
- Seven to eight hours of sleep
- Even a modest drop in weight moves blood sugar
- Stopping tobacco and limiting alcohol
- Taking prescribed medicine regularly and testing on schedule
Frequently asked questions
Can diabetes be cured completely?+
In type 2, some people bring sugar back into the normal range for long stretches through diet, weight and activity — this is called remission. It is not the same as being cured; monitoring continues. Type 1 always needs insulin.
Does rice have to be stopped entirely?+
Not necessarily. Portion size, what is eaten alongside it and the day’s overall diet matter more. Rice with dal, vegetables and salad behaves differently from rice alone.
If I avoid sweets, will I avoid diabetes?+
Cutting sugar alone is not enough. Weight, activity, sleep, stress and family history all play a part.
How often should blood sugar be tested?+
It depends on whether you have diabetes, which medicines you take and how steady your readings are. Your doctor sets that interval.
Can thin people get diabetes?+
Yes. Diabetes is seen in people of normal weight in Indian populations, so being slim is not a reason to skip testing.
