Why are my morning numbers sometimes extremely low, like 47?
If you are taking insulin or a type of diabetes pill called a “sulfonylurea,” you probably need a lower dose than you are taking. Sulfonylureas include glipizide, glyburide, and glimepiride. They work by increasing the body’s production of insulin. Too much insulin can cause hypoglycemia. Your hypoglycemia could also be related to the timing of your medications. Rapid-acting insulin is usually taken before meals to prevent the food in the meal from raising the blood glucose level. Taking rapid-acting insulin at bedtime could cause hypoglycemia overnight or in the morning.
