What Is Hypoglycemia?
Hypoglycemia is when the body's glucose levels get too low.
Glucose (a type of sugar) is the body's main energy source. Hormones, such as insulin, control the level of glucose in the blood. It's unhealthy if a person's glucose levels get too high or too low. This can happen to people who have diabetes if they don't eat enough or take too much insulin, which lowers glucose levels. Signs of hypoglycemia include feeling hungry, shaky, sweaty, weak, drowsy, or dizzy. If it's not treated, hypoglycemia can even make someone faint or pass out.
