Hypoglycemia refers to blood sugar levels that drop below the normal range. When blood sugar becomes too low, the body releases a hormone called epinephrine, which causes the body to release stored sugar into the blood. Epinephrine produces symptoms such as hunger, sweating, and shaking. As blood sugar drops even more, the body cannot get enough sugar to the brain, and additional symptoms develop due to the decrease in sugar to the brain. This causes dizziness, confusion, and weakness. As blood sugar continues to drop, and the brain does not have enough sugar to function properly, more severe effects occur, including permanent brain damage, seizures, coma, and death.
