Low Blood Sugar (Hypoglycaemia) Care in Gachibowli, Hyderabad
Hypoglycaemia is blood sugar below 70 mg/dL, usually in people taking insulin or sulfonylurea tablets. It causes shaking, sweating, hunger and confusion, and can lead to fainting if untreated. Treat it with the rule of 15: take 15 grams of fast sugar, recheck after 15 minutes, and repeat if still low. Repeated lows mean your treatment needs adjusting.
Your low-sugar prevention plan
Review your lows
When they happen, how low, and what came before: meals, activity, alcohol, medicine timing.
Check medicines
Insulin and sulfonylurea doses are adjusted, or switched to medicines with a lower risk of lows.
Monitoring
Regular finger-prick checks or a continuous glucose monitor to catch lows, including at night.
Emergency plan
Fast sugar always to hand; glucagon and family training for people at risk of severe lows.
Symptoms
- Shaking, sweating, a racing heartbeat
- Hunger, anxiety or irritability
- Dizziness, blurred vision, headache
- Confusion, slurred speech or unusual behaviour
- Nightmares, sweating at night or morning headaches (night-time lows)
- Fits or loss of consciousness (severe)
Causes & risk factors
- Insulin or sulfonylurea tablets such as glimepiride or gliclazide
- A missed or delayed meal, or eating less than usual
- More activity than usual
- Alcohol, especially without food
- Kidney disease and older age
- Losing awareness of lows after years of diabetes
Levels of hypoglycaemia
The American Diabetes Association classifies lows in three levels.
| Level | Glucose | What it means |
|---|---|---|
| Level 1 | Below 70 mg/dL | Treat now with fast sugar |
| Level 2 | Below 54 mg/dL | Clinically significant; review treatment soon |
| Level 3 | Any level, needing someone else's help | Severe; glucagon or emergency care, then urgent review |
The rule of 15
For a conscious person who can swallow:
- Take 15 grams of fast sugar: 3 to 4 glucose tablets, 150 ml of fruit juice or regular soft drink, or 3 teaspoons of sugar in water
- Recheck after 15 minutes; repeat if still below 70 mg/dL
- Once above 70, eat a snack or meal with starch and protein to stop it dropping again
- Chocolate and biscuits act too slowly because of their fat
- If the person can't swallow safely, don't give anything by mouth: use glucagon if available and call emergency help
Driving
- Check your sugar before driving if you take insulin or sulfonylureas. Many guidelines advise not driving if it is below 90 mg/dL; treat it and wait until it is back up.
How it’s diagnosed
Lows are confirmed with finger-prick readings or a continuous glucose monitor, and the pattern is reviewed against meals, activity, alcohol and medicine timing. Kidney function and HbA1c are checked, as both affect the risk of lows.
How it’s treated
Doses of insulin and sulfonylureas are adjusted, or treatment is switched to medicines with a low risk of hypoglycaemia. A continuous glucose monitor is offered to people with frequent or unnoticed lows. Every patient at risk gets a written rule-of-15 plan, and glucagon with family training where severe lows are possible.
When to seek care
- Someone with diabetes is confused, unable to swallow or unconscious: emergency
- A low that does not respond to two rounds of fast sugar
- Any severe low needing someone else's help
- Frequent lows or lows you no longer feel coming
FAQ
What is a dangerous blood sugar level?
Below 70 mg/dL needs treatment; below 54 mg/dL is significant; and any low where you need someone's help is severe.
What should I eat when my sugar is low?
15 grams of fast sugar, such as glucose tablets, juice or sugar in water. Recheck after 15 minutes, then eat a proper snack.
Can tablets cause low sugar?
Yes. Sulfonylureas such as glimepiride and gliclazide can. Metformin, DPP-4 inhibitors, SGLT2 inhibitors and GLP-1 medicines rarely cause lows on their own.
Why don't I feel my lows any more?
After repeated lows or long diabetes, warning symptoms can fade. Avoiding lows for a few weeks and using a CGM can help restore awareness.
