Diabetics are people who suffer from diabetes. The main kind of diabetes affects the pancreas, which is gland that produces a hormone called insulin. This hormone controls the amount of sugar in the blood, which provides the energy for the body. In diabetes, insufficient insulin is produced and the sugar level is uncontrolled, resulting in illness.
Diabetes usually cannot be cured. But by taking insulin and following strict rules for diet and exercise, the effects can be prevented. In the future, doctors hope that a method of automatic sugar control will be developed so that diabetics need no longer be concerned with their condition. This method could involve biosensors to monitor blood sugar levels and release insulin when it is needed.
