Hypoglycemia can ... be a common complication of diabetes. Diabetes occurs when the body cannot use glucose for fuel either because the pancreas is not able to make enough insulin or the insulin that is available is not effective. As a result, glucose builds up in the blood instead of getting into body cells. The aim of treatment in diabetes is to lower high blood sugar levels. To do this, people with diabetes may use insulin or oral drugs, depending on the type of diabetes they have or the severity of their condition. (Refer to the Diabetes protocol for further information.) Using these medications may lower their blood sugar too much, making them hypoglycemic.
