The incidence of diabetes is very high, and more people will be affected by the danger of diabetes, and will bother the daily life of patients. I hope that friends should pay attention to their dietary regimen, and observe their own health, and need to learn more about the symptoms of diabetes in life, so what are the symptoms of diabetes? The specific manifestations of diabetes: Type 1 diabetes mostly occurs in children and adolescents, and its significant pathological feature is the significant decrease in the number of insulin-producing pancreatic beta cells, resulting in a significant decrease or absence of insulin secretion. type 1 diabetes has a rapid onset, generally at an age of less than 30 years, with typical clinical symptoms of “three more and one less”, and the body shape is more The clinical symptoms of type 1 diabetes are typical. Due to the lack of insulin in the body, ketosis (the acid produced in the body when insulin is deficient) or ketoacidosis may easily develop; it may also be combined with other diseases related to immune disorders. Although type 1 diabetes is common in children and adolescents, it can occur at any age. type 2 diabetes accounts for more than 90% of the country’s diabetic population and usually starts in middle age, with a significant pathology characterized by a decrease in insulin’s ability to regulate glucose, known medically as “insulin resistance”. The onset of type 2 diabetes is closely related to ageing, obesity and certain poor lifestyles, mostly in middle-aged and elderly people and obese people. The onset of the disease is insidious, and the symptoms of “three more and one less” are often not obvious. In the early stage, there may be no symptoms, or only mild weakness and thirst. Itchy skin, especially vulva itching in women, wound healing, blurred vision, impaired kidney function, weakness of both lower limbs and a feeling of stepping on cotton, etc. may also appear. Some patients have obvious hunger before meals, or hypoglycemic reaction before meals. Some patients may have mild weight gain in the early stage of the disease. The abnormal state of glucose metabolism during pregnancy is called “gestational diabetes”, and pregnancy after the diagnosis of diabetes is called “diabetes combined with pregnancy”. The main risks of gestational diabetes include: increased incidence of perinatal lesions and mortality in pregnant women; development of type 2 diabetes after delivery; abnormal fetal development in utero; and increased risk of neonatal malformations, macrosomia and neonatal hypoglycemia. Special types of diabetes are caused by genetic defects in pancreatic β-cell function, genetic defects in insulin action, endocrine diseases, and pancreatic exocrine diseases, which are relatively rare.
