Hypoglycemia is also known as low blood sugar or glucose and occurs when the bodys glucose level
drops low enough to provide energy for the body. It usually occurs in children 10 years and older and in adults, or as a side
effect of diabetes treatment but it can result as a side effect of tumors, medication and hormone/enzymes deficicenies.
After a meal glucose molecules are absorbed into the bloodstream and carried to cells
where they are used for energy, Insulin which is made by the pancreas which allows glucose to enter the cells The body
stores extra glucose in the liver and uses it when needed between meals.
When blood glucose begins to fall, glycagon, another hormone prodiced by the pancreas signals
the liver to start breaking down glucagon and release glucose to help the sugar levels return to normal. If a person suffers
from Hypoglycemia. this ability may be impaired, especially is one has Diabetes.

Causes of Hypoglycemia
People who take glucose lowering medications can have blood sugar fall for a number of reasons such
~ meals or snacks that are too small, delayed, or skipped
excessive doses of insulin or some diabetes medications, including sulfonylureas and meglitinides
(Alpha-glucosidase inhibitors, biguanides, and thiazolidinediones alone should not cause hypoglycemia but can when used with
other diabetes medicines.)
increased activity or exercise
excessive drinking of alcohol
Hypoglycemia does not only occur in people with Diabetes. There are two types of
Hypoglycemia in non-diabetic paitents, these are Reactive Hypoglycemia (postprandial, or after meals) and Fasting Hypoglycemia
(postabsorptive) Reactivee Hypoglycemia is not usually related to an underlying problem, but Fasting Hypoglycemia is.
