Type 1 diabetes with better glycemic control and no acute or serious complications is an option to have children, but you need to consult your doctor for details. Type 1 diabetes is a type of diabetes caused by the destruction of pancreatic islet cells, resulting in absolute insulin deficiency. The vast majority of the disease is autoimmune, with a combination of genetic and environmental factors involved in its development. If the blood sugar control is good and there are no acute or serious complications, you can choose to have a child, but if the blood sugar control is not good or there are other serious complications, it is not recommended to have a child, otherwise it may lead to abnormal development or malformation of the fetus. Moreover, type 1 diabetes mellitus requires strict control of blood glucose stability throughout pregnancy, regular self-testing with a blood glucose meter, appropriate exercise during pregnancy, choosing a low-salt and low-fat diet, and timely obstetric examinations to understand the development of the fetus. Whether or not a type 1 diabetic can have a child, it is recommended to visit a hospital and consult a medical professional.
