When it comes to diabetic complications, some people may say that they have difficulty seeing or foam in their urine? These are only a small part of the complications of diabetes. In addition to these, there will be diabetic ketosis, hypoglycemia, vascular, neurological and many other acute and chronic complications of diabetes. Diabetic state, refers to the many direct and indirect causative factors caused by diabetes, including hyperglycemia, absolute and relative hypoinsulinemia, hyperlipidemia, etc. Diabetic complications are acute and chronic clinical signs and symptoms that occur in diabetes and the diabetic state, which can involve almost all organs and tissues and are a major cause of disability and death, severely affecting the quality of life of patients. Why does diabetes bring so many problems when the blood sugar is not just a little higher than normal? Because there is a disorder of sugar metabolism, the blood vessels and nerves in the body are lesioned, making the normal metabolism abnormal. For example, microvascular lesions directly affect microcirculation, which refers to the circulation of blood and lymphatic fluid in capillaries that are directly involved in material energy exchange and information transfer of tissue cells. Under normal conditions, microcirculation allows tissues to receive oxygen and nutrients and excrete waste gases and metabolized wastes. In this process, red blood cells play the most important role. It has been found that in healthy people, red blood cells are translucent, dispersed and active, while in patients with diabetes, their red blood cells tend to clump together in bunches, deform and stick together, easily blocking blood vessels. The lack of vitality and adhesion of red blood cells together is difficult to move to the end of the capillaries, which in turn causes a decrease in the function of microcirculation and the inability to complete the exchange of nutrients and waste in the body, resulting in a lack of oxygen and nutrients in the body, on the other hand, waste and toxins in the body can not be discharged, thus leading to heart disease, stroke, diabetic foot, retinopathy and other complications. In this way, these diseases have their roots in the love of diabetics, and the root cause must be eliminated in order to completely prevent and control the occurrence of diabetic complications. Therefore, a comprehensive understanding of the complications of diabetes and the factors that predispose to complications is very important not only for diabetics, but also for their family members, colleagues and friends, as the care and consideration of those around them will play a big role in reducing complications. We are also very pleased to see that some patients who have numbness in their feet will come to the hospital for examination for fear of getting diabetic foot, and this awareness of prevention is worth encouraging. The change of consciousness determines the change of action. When everyone puts the prevention and treatment of diabetic complications into the agenda of daily life, there will be less diabetic complications and the quality of life of diabetic patients will be greatly improved, truly prolonging their lives with the disease.
