But too much insulin or other diabetes medications may cause your blood sugar level to drop too low, causing hypoglycemia. Hypoglycemia can also occur if you eat less than usual after taking diabetes medication, or if you exercise more than you normally do.
Why does my blood sugar keep dropping low?
Your blood sugar is considered low when it drops below 70 mg/dL. Hypoglycemia is most common in people with diabetes. Taking too much medication (specifically sulfonylureas or insulin), skipping meals, not eating enough, or exercising more than usual can lead to low blood sugar if you have diabetes.
What happens when blood sugar levels drop too low?
Low blood sugar levels can also cause a variety of problems within your central nervous system. Early symptoms include weakness, lightheadedness, and dizziness. Headaches can occur from a lack of glucose, especially if you have diabetes. You may also feel signs of stress, such as nervousness, anxiety, and irritability.
What is considered a dangerously low blood sugar level?
Low blood sugar is called hypoglycemia. A blood sugar level below 70 mg/dL (3.9 mmol/L) is low and can harm you. A blood sugar level below 54 mg/dL (3.0 mmol/L) is a cause for immediate action.
What to do if blood sugar keeps dropping?
Hypoglycemia Treatment
If it’s below your target level or below 70, eat or drink 15 to 20 grams of carbohydrates. You can take juice, hard candy, or glucose tablets. This will usually help your symptoms go away. Check your blood sugar again in 15 minutes and treat every 15 minutes if levels are still low.
What is the best snack for low blood sugar?
Good choices include:
- a piece of fruit or handful of berries and whole-grain crackers.
- Greek yogurt mixed with berries.
- an apple with a spoonful of peanut butter and a slice of cheese.
- a small handful of mixed dried fruit and nuts.
- a no-sugar peanut butter and jelly sandwich on whole-grain bread.
How long does it take to recover from low blood sugar?
It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes.
