Common causes of diabetes

1, 1 Diabetes related factors: autoimmune system defect: because many autoimmune antibodies can be found in the blood of 1 diabetic patients, such as glutamic acid decarboxylase antibody (GAD antibody) and islet cell antibody (ICA antibody).

2. Genetic factors related to type 2 diabetes mellitus: Similar to 1 diabetes mellitus, type 2 diabetes mellitus also has the characteristics of familial disease. So it is probably related to genetic inheritance. This genetic feature is more obvious in type 2 diabetes than in 1 type diabetes. For example, one twin has 1 type diabetes, and the other has a 40% chance of suffering from this disease; But if it is type 2 diabetes, another person has a 70% chance of developing type 2 diabetes. Obesity: Obesity may be an important factor in type 2 diabetes. Genetic causes can lead to obesity and type 2 diabetes. Body-centered obese patients have excess fat concentrated in the abdomen, and they are more likely to develop type 2 diabetes than those who have fat concentrated in the buttocks and thighs. Age: Age is also a risk factor for type 2 diabetes. More than half of patients with type 2 diabetes develop symptoms after the age of 55. Elderly patients are prone to diabetes, which is also related to the overweight of the elderly. Modern lifestyle: Eating high-calorie food and reducing exercise can also cause diabetes, which some people think is also caused by obesity. Like type 2 diabetes, obesity is more common among Asian Americans and Latin American businessmen whose diet and activity habits have been "westernized". 3. Hormone abnormalities related to gestational diabetes: During pregnancy, the placenta will produce a variety of hormones for fetal development and growth. These hormones are very important for the healthy growth of the fetus, but they will block the insulin action in the mother's body, thus causing diabetes. The 24th week to 28th cycle of pregnancy is the peak of these hormones, and it is also the frequent period of gestational diabetes. Genetic basis: Patients with gestational diabetes are at great risk of developing type 2 diabetes in the future (but it has nothing to do with 1 diabetes). Therefore, some people think that the genes that cause gestational diabetes and those that cause type 2 diabetes may be related to each other. Obesity: Obesity is not only easy to cause type 2 diabetes, but also can cause gestational diabetes.
