Cold feet for the general public is not a big problem, but for diabetic patients can not be ignored, this may be the early signs of diabetic foot! Experts remind sugar lovers, if you feel the symptoms of cold feet, numb feet, must not take it lightly, should go to the hospital as soon as possible to confirm the diagnosis of diabetic foot, so as not to delay the disease, increasing the risk of amputation. Diabetic foot is an early sign of diabetic foot Diabetic foot is a disease caused by long-term failure to effectively control diabetes, resulting in atherosclerosis of the lower extremity blood vessels, diabetic foot ischemia of the lower extremity is divided into four phases: Phase 1 symptoms are often cold, numbness of the lower extremity, leg “cramps”, easily mistaken for the elderly lack of calcium, delaying the disease. Therefore, cold feet is an early sign of poor blood supply in the feet, and must be treated before it is too late. The second stage symptom is “intermittent claudication”. After walking for a certain distance, the patient gets pain in the lower limbs and is forced to stop exercising. After resting for a while, the pain is relieved, and after walking again for a certain distance, the pain appears again. As the ischemia worsens, the patient’s walking distance becomes shorter and shorter. Stage 3 is “resting pain”. The pain in the lower extremity can appear when the patient is resting, especially at night when sleeping. Stage 4 is ischemic necrosis of the tissue. In severe cases, blackened and infected necrosis of the limb may occur, leading to eventual amputation of the limb. Early detection and treatment is the best way to prevent diabetic foot, therefore, annual lower limb vascular examination is a must-do screening program for diabetic patients, and if the diabetic foot is detected early, the condition can be controlled through medication.
