There are many patients with type 1 diabetes in the clinic, most of them are young people, middle-aged and old people, but there are also some young children who develop the disease and have some abnormal symptoms, which makes many people very worried and confused, then at the age of 5, they have type 1 diabetes, what is going on? Let’s take a look at it. Type 1 diabetes is mostly caused by congenital causes Congenital diabetes belongs to type 1 diabetes in the clinic, the original name of this type of diabetes is insulin-dependent diabetes, and children and adolescents are the most prevalent groups. The onset of this disease is relatively rapid, and if the insulin in the patient’s body is absolutely insufficient, it is very easy to cause ketoacidosis, therefore, insulin must be used in the treatment in order to stabilize the patient’s condition and obtain satisfactory results, otherwise it may be life-threatening. In conclusion, the causes of congenital diabetes are relatively complex and numerous, but the main cause is the defective autoimmune system of the patient, and a variety of autoimmune antibodies are found in the blood of type 1 diabetic patients, such as the common antibodies against islet cells and glutamic acid decarboxylase, etc. These autoimmune antibodies can cause damage to the insulin-secreting B cells of the body, which cannot secrete insulin normally. These autoimmune antibodies can damage the body’s insulin-secreting B-cells and thus cannot secrete insulin properly. It is important to note that genetic defects are the basis for the onset of type 1 diabetes, and research has found that genetic defects exist in the HLA antigen abnormalities of the 6th chromosome pair. Other predisposing factors include viral infections. These are the causes of type 1 diabetes, although type 1 diabetes is mostly a congenital genetic condition that is difficult to prevent after birth, and the condition is often neglected by parents, and by the time the child is seen for treatment, the condition is already very serious. Therefore, if parents have type 1 diabetes, they should pay attention to whether their children’s bodies are different, and go to a regular hospital as soon as possible to investigate and treat any problems and medications.
