When the weather is cold, ischemic diseases of the limbs such as atherosclerosis-occlusive disease enter the high season. Mainly the weather cooling a stimulus, vascular contraction, especially prone to induce such diseases. Lower limb atherosclerosis occlusive disease refers to the formation of atherosclerotic plaque on the inner wall of the artery. As the plaque increases and the lumen narrows, the patency of the pipeline is affected, and the blood flow to the lower limb is reduced, and when the narrowing reaches a certain level or even completely blocked, the blood flow supplying the lower limb cannot meet the needs, and the symptoms of lower limb ischemia will appear. Pay attention to early symptoms This disease is most likely to be misdiagnosed and sometimes treated as a general lumbar spondylosis or calcium deficiency, especially nowadays the propaganda of some calcium supplement products can cause such misunderstanding. If arteriosclerosis occlusion of the lower limbs is not taken seriously, once it reaches the middle and late stage, it will cause severe pain or even necrosis of the affected limbs due to severe ischemia, and a considerable number of patients will have to undergo amputation. Therefore, we must pay attention to the early symptoms of this disease, the elderly once the following signs and symptoms to pay attention to: 1, the early stages of “intermittent claudication”, mainly manifested as walking calf muscle soreness, then if you sit down for a moment, the soreness can be relieved or disappear, but again after walking a certain distance pain and This is the so-called “intermittent claudication”. This is called “intermittent claudication”. 2. The symptoms of soreness, numbness and abnormal sensation are not relieved even after rest, especially at night, which is called “resting pain”. In some severe cases, ulcers and necrosis may appear at the ends of the limbs. Once “resting pain” is present, surgical treatment is required. Treatment includes general conventional treatment, medication, endovenous intervention and surgery, and the vascular surgeon will choose different treatments depending on the patient’s condition. Quit bad habits Lower extremity atherosclerosis is a slow development process, smoking and some bad lifestyle will often aggravate the development of this disease, self-care of the elderly is very important to prevent the emergence of lower extremity atherosclerosis occlusive disease. First of all, you should quit smoking. Nicotine and other harmful substances in tobacco can cause a prolonged spasmodic constriction of small blood vessels at the end of the limbs, resulting in a sharp reduction in the blood supply to the skin, muscles and nerve tissue. This effect on the lower extremity artery stenosis or occlusion of patients in addition to aggravate atherosclerosis, but also lead to severe ischemia of the limbs already undersupplied with blood, and even toe blackening necrosis. Secondly, it is important to avoid high sugar and high fat diets and reduce cholesterol intake in the diet.
