Arterial thrombosis (arterial embolism) is a condition in which an embolus dislodged from the wall of the heart or artery travels distally with the blood flow, blocking the vessels distal to it and affecting the blood supply to the tissues, resulting in ischemia or necrosis of the limb. However, in some cases, the collateral circulation is opened locally after the arterial embolism. And make the distal limb maintain blood circulation, not ischemic symptoms, due to severe limb ischemia, nerve blood supply within the limb is blocked, resulting in peripheral nerve dysfunction, the initial limb can be found sensory hypersensitivity, gradually glove-like sensation loss, sensory numbness, muscle weakening or paralysis, limb can not move, so how to prevent it? Hyperlipidemia, hypertension, smoking, diabetes, obesity, and low HDL are the risk factors for this disease, so prevention is also a priority. Strict control of these risk factors can effectively achieve the purpose of prevention. 1. The total calorie content of the diet should not be too high, in order to maintain the ideal body weight. 2.Overweight people should control the total calories eaten daily, consume low-fat and low-cholesterol diets, and limit the intake of sucrose and sugar-containing foods. 3.For those who have been diagnosed with atherosclerosis occlusive disease, overeating is strictly prohibited to avoid serious consequences. For those who have hypertension or heart failure, salt and sodium-containing foods should be restricted at the same time. 4.Advocate a light diet and eat more foods rich in vitamin C and vegetable protein. Under possible conditions, try to take soybean oil, vegetable oil, sesame oil, corn oil, tea oil and rice bran oil as cooking oil.
