When the blood sugar is high, it is really painless at first, but its damage to the body has not stopped for a minute. There is 1 diabetic in every 10 adults in China, and the complications caused by diabetes make people talk about it. Today, let's demystify diabetes and understand how it can harm our physical health step by step. 
High blood sugar is harmful to blood vessels
Increased blood viscosity:High blood sugar can lead to an increase in glucose in the blood, which increases blood viscosity, which is easy to form blood clots and affects blood circulation.
Vascular lesions:Hyperglycemia can cause macrovascular lesions, such as atherosclerosis, which make blood vessels thinner, brittle, and less elastic. At the same time, microangiopathy can also occur, such as diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, etc. Vascular endothelial damage:High blood sugar damages vascular endothelial cells, disrupting the integrity of blood vessel walls and impairing the natural barrier between blood and vessel walls. Narrowing of blood vessels:When the vascular endothelium is damaged, platelets are activated, forming a thrombus and attracting fat deposits under the endothelium, narrowing the local blood vessels. Blood thickening:In the state of high sugar, the more glucose in the blood, the more concentrated the blood, and the blood flow is slow and stagnant, which increases the viscosity of the blood and is more likely to show a hypercoagulable state.
Vascular lipidation:Glucose metabolism in the human body is closely related to lipid metabolism, and when glucose metabolism is abnormal, blood lipids are also prone to problems. 
The harm of high blood sugar is not only limited to the blood vessels, but also causes damage to the nervous system. High blood sugar destroys nerve fibers, causing damage to the nervous system. When blood vessels are damaged and unable to nourish nerves, complications such as diabetic foot can ensue. High blood sugar can also destroy the body's immunity, making patients more susceptible to viruses, bacteria, etc., further aggravating the body's damage. Diabetic foot is due to the superposition of heavier lesions, the small wounds on the feet are difficult to heal, and microbial infections are added. Because of the sensory impairment, the patient cannot detect the wound in time. Eventually, the wound becomes larger and larger, the infection deepens, ulcerates and even dies, and many patients can only amputate their limbs to save their lives when they come to the doctor.
How to prevent diabetic foot in daily life
Active blood sugar control:People with diabetes should take proactive steps to keep their blood sugar within the ideal range and reduce the risk of complications. Blood sugar control is the foundation of diabetes.
Adjust your diet:Maintain a balanced diet, reduce the intake of high-sugar, high-fat and high-salt foods, and increase the intake of dietary fiber.
Increase Exercise:Increasing the amount of exercise appropriately improves the body's metabolism and helps lower blood sugar.
Regular check-upsDiabetic patients should regularly check the functions of blood vessels, nerves and other functions to find and develop potential problems in time.
Maintain good habits:Quit smoking, limit alcohol, get enough sleep, and avoid excessive stress. 
Diabetic patients should pay great attention to blood sugar control to prevent the sugar in the blood vessels from corroding our feet step by step. Only by doing a good job of self-management can we delay the onset of complications and improve the quality of life. Let's join hands to fight diabetes and protect vascular health!
