After entering winter, many elderly people and diabetic patients begin to feel uncomfortable in both legs. Lighter feeling of two feet and cold and numb, walking on a few dozen meters feel tired legs, leg pain, rest for a while and then walk, walk the same distance, the above symptoms again; heavier feeling of two legs cold, numbness is more obvious, do not feel leg pain, some night pain to sleep; and then heavy appear two legs, two feet skin purple, and even black toes. Many people think it is because they are older, physical strength is not good, but do not know that this is often a problem with the arteries in your legs. Older people as they age, the chances of atherosclerosis are getting higher and higher, the arteries inside the growth of small and large plaques, resulting in the blood vessels become thinner and thinner, and in severe cases even completely occluded, the flow of blood to the legs and feet significantly reduced. When this blood flow is reduced to a certain level and cannot meet the needs, the legs and feet begin to appear cold, numb, painful and other manifestations, and then in severe cases, there is necrosis of the limbs, eventually leading to toe amputation or amputation. One of the main complications of diabetes is vasculopathy, which causes hardening and plaque formation in arteries throughout the body, resulting in arterial narrowing or occlusion, the same symptoms as those caused by simple atherosclerosis. However, diabetic patients are more likely to have arteriopathy in the lower legs, which is often more problematic in terms of treatment, because the narrowing and occlusion of small vessels are often not suitable for stenting and surgical “bypass” treatment, and balloon dilation can be performed for shorter vascular lesions, while long vascular lesions often involve the entire lower leg, so there is no way to treat them. If you have a long vascular lesion, you can only apply medication or try bone marrow stem cell therapy. When you find yourself with the above symptoms, you must be alert and go to the hospital for an ultrasound to see if there is a problem with the arteries in your legs or not. This kind of arterial stenosis and occlusive lesions are relatively simple to treat in the early stage, whether it is putting stents or doing vascular “bypass”, the effect is often more satisfactory. If the disease is ignored for a long time, without active treatment of hypertension and diabetes, and without quitting smoking, it will become more and more difficult to treat as the disease progresses, and its efficacy cannot be fully guaranteed. Therefore, we would like to remind you that for your own health, please make sure to develop a good awareness of health care, and once you find a problem, seek early diagnosis and treatment, so that you can have a healthy body to enjoy your old age.
