As the weather gets colder, many middle-aged and elderly people will feel cold in their lower limbs, and after walking for a certain distance, they will experience soreness and numbness in their calves, thighs and even hips, as well as pain, and have to stop and rest for a while before they can continue walking, which most people will not think of as a result of their age. In fact, this is caused by atherosclerosis involving the arteries of the lower extremities, and if we do not pay enough attention to it, the walking distance will become shorter and shorter, and the pain will gradually increase, and eventually the pain will appear even if we do not walk, which is what we call “resting pain”. Once resting pain occurs, treatment can be quite tricky, sometimes resulting in localized toe necrosis and, in severe cases, toe amputation or even amputation. Therefore, we should cherish the two legs that play an important role in supporting our lives, and it is crucial to prevent atherosclerotic occlusive disease in the lower extremities before it happens. Atherosclerosis is a diffuse lesion, often involving the brain, heart, kidney and other important organs of the arterial blood supply, so prevention is particularly important. First of all, people suffering from hypertension, hyperlipidemia and diabetes should actively treat the original disease to avoid aggravating the damage to blood vessels. Secondly, diet should be reasonably regulated to prevent disorders of lipid metabolism and high blood cholesterol. After middle age, you should avoid eating too much animal fat and foods with high cholesterol. Eat more foods rich in vitamins, such as fresh vegetables, beans, soy products, vegetable oils, various fruits, etc. Avoid high-fat diet, high sugar, indigestible and stimulating food, diet should be light; Third, from the young should pay attention to develop good habits, often appropriate physical exercise and physical labor, usually can do some appropriate regular walking exercise, give up smoking, alcohol and other bad habits; Fourth, once the lower limb atherosclerosis occlusive disease do not panic, as long as the timely treatment of the symptoms It is fine. But go to a regular hospital under the guidance of a specialist to take some drugs to dilate blood vessels and improve microcirculation to promote blood circulation in the affected limbs. If medication does not improve, minimally invasive treatment can be performed under local anesthesia to reopen the blood vessels in the lower limbs and restore blood flow. In addition, appropriate exercise should be carried out, but the walking pace should not be too fast to avoid the onset of ischemic symptoms, and heavy objects should not be moved; the affected limb should pay attention to heat preservation, and when the foot becomes cold, you should not rashly warm the foot with a warm water bag or soak it in hot water, because this will aggravate the ischemia of the lower limb and worsen the condition.
