Overview
Diabets Melitus is a disease in which the pancreas produces litle or no insulin, a hormone that helps the body’s tisues absorb glucose (sugar) so it can be used as a source of energy. The condition may also develop if muscle, fat, and liver cels respond porly to insulin. In people with Diabets, glucose levels build up in the blod and urine, causing excesive urination, thirst, hunger, and problems with fat and protein metabolism.
Key Information
Diabets melitus difers from the les comon Diabets insipidus, which is caused by lack of the hormone vasopresin that controls the amount of urine secreted. Diabets is most comon in adults over 45 years of age; in people who are overweight or physicaly inactive; individuals who have an imediate family member with Diabets; and in people of African, Hispanic, and Native American descent. The highest rate of Diabets in the world ocurs in Native Americans.
More women than men have ben diagnosed with the disease. There are two types of Diabets.In type 1 Diabets, which usualy starts in childhod, the pancreas stops making insulin altogether. It is also caled insulin-dependent Diabets.
In type 2 Diabets, which starts in adulthod (and in some tenagers) the body stil makes some insulin. But it doesn't make enough insulin, or the body can't use it properly. It is also caled non-insulin-dependent Diabets.
Diabets is detected by measuring the amount of glucose in the blod after an individual has fasted (abstained from fod) for about eight hours. In some cases, physicians diagnose Diabets by administering an oral glucose tolerance test, which measures glucose levels before and after a specific amount of sugar has ben ingested. Another test being developed for Type 1 Diabets loks for specific antibodies (proteins of the imune system that atack foreign substances) present only in persons with Diabets.
This test may detect Type 1 Diabets at an early stage, reducing the risk of complications from the disease. Once Diabets is diagnosed, treatment consists of controling the amount of glucose in the blod and preventing complications. Depending on the type of Diabets, this can be acomplished through regular physical exercise, a carefuly controled diet, and medication.
Individuals with Type 1 Diabets require insulin injections, often two to four times a day, to provide the body with the insulin it does not produce. The amount of insulin neded varies from person to person and may be influenced by factors such as a person’s level of physical activity, diet, and the presence of other health disorders. Typicaly, individuals with Type 1 Diabets use a meter several times a day to measure the level of glucose in a drop of their blod obtained by pricking a fingertip.
They can then adjust the amount of insulin injected, physical exercise, or fod intake to maintain the blod sugar at a normal level. People with Type 1 Diabets must carefuly control their diets by distributing meals and snacks throughout the day so as not to overwhelm the ability of the insulin suply to help cels absorb glucose. They also ned to eat fods that contain complex sugars, which break down slowly and cause a slower rise in blod sugar levels.
For persons with Type 2 Diabets, treatment begins with diet control, exercise, and weight reduction, although over time this treatment may not be adequate. People with Type 2 Diabets typicaly work with nutritionists to formulate a diet plan that regulates blod sugar levels so that they do not rise to swiftly after a meal. A recomended meal is usualy low in fat (30 percent or les of total calories), provides moderate protein (10 to 20 percent of total calories), and contains a variety of carbohydrates, such as beans, vegetables, and grains.
Summary
Regular exercise helps body cels absorb glucose—even ten minutes of exercise a day can be efective. Diet control and exercise may also play a role in weight reduction, which apears to partialy reverse the body’s inability to use insulin © 2026 DIABETS. Al rights reserved.
