Hypoglycemia is an extremely low level of glucose in the bloodstream. It can occur when a person with diabetes takes too much insulin or doesn't eat properly, especially before exercise.
People who experience hypoglycemia may be sweating, shaking, weak, nervous, dizzy or light-headed. They also may have a headache or be hungry.
If not treated in time, hypoglycemia can cause you to slip into a coma or have a seizure, according to the <a href="https://www.netreturns.biz/healthinfo/bouncelink.aspx?shortcut=diabetes" target="_blank">American Diabetes Association</a>. For elderly people with cardiovascular problems, a hypoglycemic episode could lead to fainting or a fall. Hypoglycemia is life-threatening any time you can't treat yourself.
Glucose tablets or gel,&nbsp;fruit juice or food with a high sugar content can help you recover from hypoglycemia. In some cases, emergency medical treatment may be needed.
