How diabetes develops Generally speaking, the body turns the starchy food it eats into glucose, which is used as fuel for the body, and insulin, a hormone produced by the pancreas, allows glucose to enter the cells and provide heat. Diabetes refers to the inability of the pancreas in the body to produce enough insulin, resulting in the inability of glucose to enter the cells sufficiently, and the blood glucose concentration rises to form diabetes. Therefore, a series of symptoms that occur as a result of a disruption of glucose metabolism due to an absolute or relative deficiency in insulin production is called diabetes mellitus. The disease is currently classified into two types: insulin-dependent (also known as type I diabetes) and non-insulin-dependent (also known as type II diabetes). The onset of the disease is associated with genetic factors. Common complications include tuberculosis, septic skin disease, hyperlipidemia, atherosclerosis, coronary artery disease, nephropathy, cataract, fundus retinopathy and neuropathy. The most serious complications are ketoacidosis coma and non-ketotic hyperosmolar coma, which can lead to death if not rescued in time. The prevention of diabetes should be constructed in three “lines of defense”, which is called tertiary prevention in medical science. If the “lines of defense” are laid, constructed in a timely, reasonable and solid manner, most diabetes can be prevented. Primary prevention means minimizing the incidence of diabetes. As you know, diabetes is a non-communicable disease, and although there are certain genetic factors at play, it is the acquired life and environmental factors that play a key role. It is now known that excessive caloric intake, overnutrition, obesity, and lack of exercise are important causes of the onset of the disease. These causes are closely related to people’s view of eating and lifestyle, and once habits are formed, it naturally makes it more difficult to correct them. Proper caloric intake, low sugar, low salt, low fat, high fiber, and adequate vitamins are the best diet; regular monitoring of body weight and maintaining it at a normal level for a long time is also crucial. When weight gain occurs, diet restriction and increased exercise should be taken to bring it back to normal as soon as possible. Exercise should become an organic component of life, exercise can not only consume excess heat, maintain muscle mass, and can improve the sense of fulfillment and euphoria. Of course, exercise should be scientific and artistic, step by step, according to the ability, to take care of interest, easy to obtain results and easy to adhere to in partnership. To eliminate all bad habits, quit smoking and drink less alcohol. It is especially important to strengthen prevention and monitoring for high-risk groups, such as those with two parents with diabetes, obese and overeating, high blood sugar, middle-aged and elderly people, and those who lack exercise. Secondary prevention is the early detection of diabetic patients and active treatment. Blood glucose measurement should be included in the routine physical examination program for middle-aged and elderly people, and even for those who are normal once, it should still be measured regularly. Anyone with signs of diabetes, such as abnormal skin sensation, reduced sexual function, poor eyesight, polyuria, cataracts and other symptoms, should be carefully identified in order to make early judgments and gain valuable time for early treatment. Once diabetes is diagnosed, the concept of lifelong struggle should be established, and the means of diet, exercise and medicine should be mobilized to control blood glucose smoothly at or near normal level for a long period of time, instead of satisfying the temporary control. Fasting blood sugar should be below 6.67mmol/L (120mg%), 2 hours after meal blood sugar below 7.85mmol/L (about 140mg%), and glycosylated hemoglobin below 7.0%, which can reflect the chronic blood sugar level. The aim of tertiary prevention is to delay the occurrence and development of chronic comorbidities of diabetes and to reduce their disability and mortality. It is important to strengthen the monitoring of chronic comorbidities of diabetes and to achieve early detection. Early prevention is its main point, and late treatment is not effective. Early assertion and early treatment can often prevent its occurrence and enable patients to lead a near-normal life in the long term. At present, diabetes is still a lifelong disease and there is no cure, but this does not mean that the concept of doing nothing and letting it happen can be held. If you are not yet a diabetic, you should regulate your life and make your lifestyle scientific, this is the most important and strongest line of defense, if you do not pay attention, you are likely to become a future diabetic; if you are already a diabetic, there is no need to be pessimistic, as long as long-term control is good, it is possible to prevent and effectively delay chronic complications of diabetes. If you are already a diabetic, there is no need to be pessimistic, as long as long-term control is good, it is possible to prevent and effectively delay the occurrence and development of chronic complications of diabetes.
