What Is Hypoglycemia?

Hypoglycemia means your blood sugar level is lower than normal. Usually, blood sugar gives your body energy. When it drops too low, your body cannot work well. In the United States, many people with diabetes face hypoglycemia. However, it can also happen to people without diabetes. Knowing about hypoglycemia helps you spot problems early. This way, you can stay safe and healthy.
