Nocturnal hypoglycemia refers to a drop in blood sugar below 70 mg/dL while sleeping. When you are awake, you can immediately deal with a drop in blood sugar, but it is dangerous because it is not easy to recognize while sleeping. If you have low blood sugar at night, you may have nightmares or be pressed by scissors while sleeping, and your pajamas and pillow may get wet due to cold sweat. You may experience a headache when you wake up in the morning.
Causes of nighttime hypoglycemia include △drinking too much alcohol or not eating enough in the evening △high-intensity exercise in the afternoon or evening without adjusting the insulin injection dose △a large dose of long-acting insulin or short-acting (fast-acting) insulin in the evening There are cases where the dose of super fast-acting insulin is large.
To prevent hypoglycemia at night, keep your blood sugar between 100 and 140 mg/dl before bed and eat a snack containing carbohydrates and protein if your blood sugar is below 100 mg/dl before bed. If you did high-intensity exercise in the afternoon or evening, or if your dinner was small and your protein intake was insufficient, measure your blood sugar around 2-3 am.
According to the Korea Diabetes Association, if your blood sugar is less than 70mg/dl at night, immediately take a low-glycemic emergency food such as half a cup of sugar-sweetened juice or 3-4 candies. If blood glucose is between 80 and 130 mg/dl after resting for 10 to 15 minutes, take 1 exchange unit of fruit or milk group to prevent hypoglycemia from reoccurring until morning. If your blood sugar is below 70 to 100 mg/dl, it is not hypoglycemic, but it can be uncomfortable, so take a hypoglycemic emergency food immediately. After eating a low-glycemic emergency food, consume 1 exchange unit of fruit or milk group.
