Type 2 diabetes is caused by insulin resistance. This means that the body cells are less and less responsive to insulin, until they become insensitive - resistant. The hormone can then no longer infect the sugar into the cells. As a result, the blood glucose level increases. Causes of insulin resistance are mainly hereditary predisposition, overweight and lack of exercise. For the treatment usually start at the beginning of weight loss, sports and tablets. Only if after many years of disease duration insulin production saves, patients with type 2 diabetes need to inject insulin. Proper follow up is necessary to cure the diabetes. Type 1 diabetes , on the other hand, is an autoimmune disease. The defense system of the own body often destroys the insulin-producing cells, which are located in the pancreas, within a few weeks. This leads to a deficiency of insulin. Why it comes to the autoimmune reaction in type 1 diabetes, has not yet been clarified.If you have type 1 diabetes, you need to inject insulin from the beginning to control your blood glucose level. Often the disease is already occurring in the age of children and adolescents. Type 1 diabetes is not curable. The course of the disease can not be influenced by lifestyle measures. Protein is good for maintaining health.In addition to type 1 and type 2 diabetes, there are a number of other forms of diabetes that are very rare.
