When you think of diabetes, you usually only think of middle-aged and elderly people. However, in recent years, some children around us have developed type 2 diabetes at the age of just a few years. In the long run, if diabetes is not well controlled at a young age, various complications such as blindness and kidney failure will follow in a few years, which will bring a heavy financial and mental burden to the child’s life. Due to the increasing number of obese children, the ranks of children with type 2 diabetes are getting larger and larger. It has been reported that in Japan, the incidence of type 2 diabetes in children doubles every 1O years on average, and type 2 sugar disease has accounted for 80% of all diabetes in children, much higher than type 1 diabetes. In China, 1 in 10 diabetic patients are now adolescents, and the fastest growing type 2 diabetes is among them. As with adult diabetes, children with diabetes need adequate exercise, not only for treatment, but also for growth and development. Proper exercise can bring many benefits to children with diabetes, such as increasing muscle sensitivity to insulin, which is good for blood sugar control; improving cardiovascular function, which is good for preventing cardiovascular disease; and promoting the development of bones and muscles in children with diabetes. In principle, children with diabetes need to participate in more than one hour of moderate exercise every day. It is best to exercise regularly and quantitatively, and follow the principle of individualization and gradual progress in order to receive good therapeutic effects. So what should be noted when children with diabetes exercise? 1, children with diabetes must do a good job of insulin and diet regulation before exercise, before strenuous exercise need to increase the amount of diet or carry to prepare hunger food or candy. If necessary, the insulin dosage can also be reduced by 10%. 2.The choice of some interesting sports activities is convenient for the children to adhere to for a long time, such as cycling, running, playing badminton, table tennis, playing soccer, skipping, playing shuttlecock, jumping rope, etc., are all good ways of physical exercise. 3.Because of the accelerated blood flow in the limbs during exercise, insulin absorption is increased, thus the injection site can be changed to the abdomen for children with insulin injection. 4.Choose appropriate clothing and shoes and socks, and pay attention to cleanliness and hygiene after exercise. 5.If possible, parents can participate in sports together with their children, which will increase children’s interest in sports and enhance the relationship between parents and children. 6, children’s self-control is relatively poor, sometimes addicted to play can not stop, so that forget to take injections, meals, should be careful to avoid. 7, in physical exercise, more attention should be paid to avoid the occurrence of hypoglycemia, the weather is too hot, exercise for too long, but also to prevent dehydration, exercise is best to carry a little food and water, so that in the event of hypoglycemia or thirst to eat. 8. High climbing and diving should be avoided because it is dangerous if hypoglycemia occurs during high climbing and diving. Children with insulin injections should avoid the above exercises during the peak of insulin action to avoid the occurrence of hypoglycemia and unpredictability. 9. Those who have retinal complications should not play strenuous sports. 10.If the child has cold, fever, diabetic ketoacidosis, blood sugar >16.7mmol/L; ketone bodies in urine, abnormal sensation in feet or lower limbs, sudden and severe pain in body, blurred vision, he/she should rest in bed and avoid sports. As the blood glucose of children with diabetes fluctuates greatly, if the blood glucose control is too strict, it will cause hypoglycemia, which may cause serious harm to the children. Therefore, the standard of blood glucose control for children with diabetes is much more lenient than that for adults. Studies have concluded that the goal of long-term glycemic control for children and adolescents with type 1 diabetes is to maintain glycosylated hemoglobin (HbAlc) below 7.5% without severe hypoglycemia, and the goal of short-term glycemic control is 4-8 mmol/L for preprandial blood glucose and ≤10 mmol/L for postprandial blood glucose, which is more reasonable. If you want to get good blood sugar control, it is better to monitor blood sugar more than 4 times a day. For children with persistent hypoglycemic coma and recurrent hypoglycemia or hyperglycemia, an ambulatory glucose monitoring system can be used. From the perspective of preventing chronic complications, it is desirable to have blood glucose and HbAlc control as normal as possible, but this is difficult to achieve in pediatric and adolescent patients, and children, especially those under 6 years of age, often have unconscious hypoglycemia due to the immaturity of the counter-regulatory system and lack of cognitive and responsiveness to hypoglycemia, putting them at higher risk of hypoglycemia and its sequelae. If the target HbAlc is set too low it will increase the risk of hypoglycemia, while setting it too high will increase the incidence of distant microvascular complications. If HbAlc is consistently >9.5%, the risk of ketoacidosis and long-term complications is greatly increased. Therefore, weighing these two considerations, the 2006 American Diabetes Association published standards for the diagnosis and management of diabetes that set age-related glycemic and HbAlc control goals for children.
