With age, many older people are suffering from atherosclerotic diseases, such as hypertension, coronary heart disease, cerebral infarction, etc., not realizing that atherosclerosis is also quietly tired of our legs. Many elderly people have had such an experience, walking no strength or leg pain, rest for a while, feel better and continue to walk for a while and then no strength to rest for a while. Some people’s feet and even legs are easy to cold, numbness, sometimes like pins and needles general pain. Many people take this as a manifestation of calcium deficiency, calcium supplements a lot, but the symptoms in turn do not get better, this is how it is? Atherosclerotic lesions is a systemic disease, occurring in some large and medium-sized arteries, lesions of arterial thickening, hardening, accompanied by atherosclerotic plaques and calcification, and can be secondary to thrombosis, resulting in arterial lumen stenosis or occlusion, the formation of the corresponding parts of the infarction and ischemia of the distal tissues. This lesion occurs in the brain tissue, that is, the formation of cerebral infarction; occurs in the heart, that is, the formation of coronary heart disease; and such as occurs in the lower part of the abdominal aorta, iliac arteries, femoral arteries and N arteries, etc., will form the corresponding part of the limb ischemic symptoms. Coldness, numbness, pain, intermittent claudication and ulceration or necrosis of the toes or feet will occur in the affected limbs. This is senile vasculitis, scientific name: limb arteriosclerosis occlusive disease. In recent years, more and more patients with lower limb atherosclerosis occlusive disease, data show that at present, in people over 50 years old, the incidence of this disease reaches 2%-3%, of which the incidence of diabetic patients is even higher, 20% of diabetic patients will suffer from this disease, and the onset of the disease is earlier than non-diabetic patients, the condition is more serious. When the following symptoms occur, you have to be alert: at the beginning of the feeling of cold feet, skin temperature decreases, with the aggravation of the disease, the above symptoms are more obvious, and characteristic symptoms – intermittent claudication, resting pain, and even woke up in pain in the sleep, or sitting on the knees, sleepless nights. The skin color of the affected foot is pale or cyanotic, producing ulcers and gangrene on the toes, feet or lower legs under severe ischemia. Especially patients with diabetes are more likely to develop wet gangrene and secondary infection, and in severe cases, amputation is necessary. Atherosclerosis obliterans has a prolonged course and severe symptoms, which makes people with the disease suffer a lot of pain and the quality of life is seriously reduced. At present, according to the degree of atherosclerosis, symptoms and complications, vasodilators, lipid-lowering drugs, antiplatelet drugs, and drugs affecting the absorption of lipoproteins by the arterial wall can be applied. In severe cases, according to the location and degree of vascular occlusion, vascular surgery can be chosen. Atherosclerosis is the root cause of arteriosclerotic occlusive disease of the lower limbs, therefore, to prevent the occurrence of this disease, it is necessary to prevent atherosclerosis. Atherosclerosis is an irresistible phenomenon according to the natural law of metabolism. However, the arrival of atherosclerosis can be delayed and the degree of atherosclerosis can be reduced through active prevention. Avoid smoking, alcoholism and other bad habits; reasonable diet, eat less fat, less salty; appropriate exercise, strengthen the body. For diabetic patients or people with a family history of diabetes, it is more important to start from the lifestyle, active prevention, blood sugar control. For those who are already sick local insulation is very important, in addition, to avoid trauma and infection, the pain should be used medication for pain relief to reduce pain.
