There are several types of diabetes?

According to the pathogenesis of diabetic mechanism has been divided into four different types, which is the largest incidence of type 1 and type 2 diabetes. Type 1 diabetes, in the past often called insulin-dependent diabetes, is an autoimmune disease, Diabetic patients about 10% of the total, but more common in children and adolescents. Type 1 diabetics more rapid onset, "a little more than three" obvious symptoms, high ketoacidosis, Some of the first patients on treatment performance for ketoacidosis. Their blood glucose level fluctuations, and fasting plasma insulin level low. This type of diabetes generally need to rely on insulin therapy or exogenous insulin dependent. must use exogenous insulin therapy, it will be recurring ketoacidosis, or even lead to death. As the disease progresses, the islet beta cells in the successful line damage Finally, the patient must rely on exogenous insulin to control blood sugar levels and inhibiting ketone body production. Type 2 diabetes, in the past are usually referred to as non-insulin-dependent diabetes, or adult-onset diabetes, Diabetic patients about 90% of the total. Multiple aged over 40 in the adults and the elderly, there is a clear genetic family. Patients with type 2 diabetes onset majority of the relatively slow, and it was over obesity and mild, dry mouth, thirst and other symptoms, many have even asymptomatic, less ketoacidosis. Clinically, "more than three" can not obvious symptoms, often in the medical examination or treatment for other diseases was found. Most patients in the control diet and oral hypoglycemic agents after treatment to control blood sugar stable. However, some patients, especially longer duration of diabetes, more than 20, emaciation of elderly diabetic patients there insulin level is low, need exogenous insulin to control blood sugar. There are also a small number of patients suffering from diabetes or pregnancy is a special type diabetes.
