Insulin resistance is mostly seen in type 2 diabetes and specific types of diabetes. Diabetes is a chronic metabolic disease with a predominantly elevated blood glucose level and is mainly divided into four types: including type 1 diabetes, type 2 diabetes, specific types of diabetes and gestational diabetes. The occurrence of diabetes is dominated by varying degrees of insulin resistance, and varying degrees of insulin deficiency. The specific insulin resistance or insulin deficiency is related to the type of diabetes, as follows: 1. Type 1 diabetes is mostly seen in adolescents and children, with a lean body type, insulin deficiency and pancreatic β-cell failure, so the treatment of type 1 diabetes needs to rely on insulin. 2. Type 2 diabetes is the type of diabetes that accounts for the largest number of people with the disease, mostly seen in patients older than 40 years old. Patients with type 2 diabetes have both insulin resistance and insulin deficiency. Especially in the early stage of the disease, insulin resistance is predominant, and patients with type 2 diabetes who have a long disease duration, are wasting and have a significant increase in blood glucose also have a more serious insulin deficiency.3. Gestational diabetes also has a heavy insulin resistance because of the presence of placental antagonistic hormones, but gestational diabetes must be treated with insulin.4. Other special types of diabetes, such as type A insulin resistance and type B insulin resistance There is also a heavier insulin resistance.
