Before the discovery of insulin in 1921, everyone with type 1 diabetes died within a few years after diagnosis. Although insulin is not considered a cure, its discovery was the first major breakthrough in diabetes treatment.

Today, healthy eating, physical activity, and insulin via injection or an insulin pump are the basic therapies for type 1 diabetes. The amount of insulin must be balanced with food intake and daily activities. Blood glucose levels must be closely monitored through frequent blood glucose checking.

Healthy eating, physical activity, and blood glucose testing are the basic management tools for type 2 diabetes. In addition, many people with type 2 diabetes require oral medication and insulin to control their blood glucose levels.

People with diabetes must take responsibility for their day-to-day care. Much of the daily care involves keeping blood glucose levels from going too low or too high. When blood glucose levels drop too low from certain diabetes medicines--a condition known as hypoglycemia--a person can become nervous, shaky, and confused. Judgment can be impaired. If blood glucose falls too low, a person can faint.

Treatment of type 1 diabetes: Type 1 Diabetes must be treated with insulin shots. This involves injecting insulin under the skin -- in the fat -- for it to get absorbed into the blood stream where it can then access all the cells of the body which require it. Insulin cannot be taken as a pill because the juices in the stomach would destroy the insulin before it could work. Lack of insulin production by the pancreas makes type 1 diabetes particularly difficult to control. Treatment requires a strict regimen that typically includes a carefully calculated diet, planned physical activity, home blood glucose testing several times a day, and multiple daily insulin injections.

Treatment of type 2 diabetes: Treatment typically includes diet control, exercise, home blood glucose testing, and, in some cases, oral medication and/or insulin. Approximately 40 percent of people with type 2 diabetes require insulin injections.
