Diabetes

Self-monitoring

Hypoglycemia happens if your blood glucose drops too low. It can come on fast. It is caused by taking too much diabetes medicine, missing a meal, delaying a meal, exercising more than usual or drinking alcoholic beverages. Sometime, medicines you take for other health problems can cause blood glucose to drop. Hypoglycemia can make you feel weak, confused, irritable, hungry or tired. You may sweat a lot or get a headache or feel shaky. If your blood glucose drops too low, you could pass out or have a seizure.

If you have any of these symptoms, check your blood glucose.
