With the improvement of living standards, people are becoming more and more concerned about their health. More and more people are concerned about blood lipids because there are many health problems associated with abnormal blood lipids. Today, we will talk about the lesions and manifestations of elevated lipids in the legs. It is a relatively common phenomenon, which is an abnormality in the metabolism of lipoproteins in the body, mainly including total cholesterol and LDL cholesterol, elevated triglycerides and/or reduced HDL cholesterol. Elevated lipids are one of the important factors leading to atherosclerosis, which causes thickening and hardening of arterial walls and narrowing of the lumen of blood vessels. It is an independent risk factor for coronary heart disease and ischemic stroke. The high incidence of dyslipidemia in China and the trend of gradual increase are closely related to the obvious improvement of the living standard of our people and the change of dietary habits. Elevated blood lipids, atherosclerosis occurs in the legs, and if the narrowing severely blocks the lumen of the artery, the downstream tissues supplied by that artery will be ischemic or necrotic. The legs will have the following manifestations: 1, abnormal skin sensation in the legs High blood lipids can cause arteriosclerosis in the legs, and when the narrowing of the arteries in our legs leads to insufficient blood supply, the skin on the legs will be cold, numb and painful, and the well-known “old cold legs” is one of the manifestations of this disease. This is because the arterial lumen narrowing, poor blood supply, leg tissue ischemia, lack of oxygen caused by. 2, intermittent claudication Sometimes there are intermittent pain symptoms in the legs, which are normal at rest, but when walking a distance or climbing stairs, the legs will be sore and painful, which can be relieved after rest, and the pain will be repeated after repeated exercise, this symptom is called “intermittent claudication”. 3, foot skin ulceration, blackening, gangrene Severe cases may have persistent pain, lower limb arteries, especially the dorsalis pedis artery pulsation is weak or disappeared. If the arterial lumen is completely occluded, it can produce skin ulceration, blackening and gangrene of the foot. If there is a problem with blood lipids, attention should be paid to the prevention of atherosclerosis. You should pay attention to do more aerobic exercise in general, exercise can lose weight, control weight, but also lower blood pressure, drink more water, avoid smoking and limit alcohol, eat more vegetables and fruits, live a regular life, avoid overworking and staying up late, and keep a happy and relaxed mood. If you have lower limb atherosclerosis, you must start taking lipid-lowering and plaque stabilizing drugs for intervention and treatment. Those with heavy stenosis may need further intervention or surgery.
