With the development of our society, the number of people suffering from diabetes is increasing year by year. Nowadays, basically every family will have a relative who is a diabetic. And with the popularity of information technology, diabetic patients and their families, more or less, are aware of the complications. For example, if you can’t see clearly, you will be reminded by the king next door that your eyesight is affected by high blood sugar. Or “foam” in the urine. Although more or less inaccurate, it shows that people know that diabetes can affect the kidneys and eyes. However, there is another complication that is closely related to our lives, which is easily overlooked and has more serious “consequences” after the disease. What is diabetic foot? It is an infection, ulcer, and/or deep tissue destruction of the foot associated with nerve abnormalities and varying degrees of peripheral vascular disease in the distal lower extremities. Simply put, it is a diabetic patient with lower extremity vasculopathy, or lower extremity neuropathy, along with foot breakdown, infection, etc. How serious are the consequences of diabetic foot? Diabetic foot ulcers and infections are difficult to control and often lead to amputation, causing great pain to the patient’s heart and inconvenience to his or her life. There are two simple reasons why diabetic foot can have such serious consequences. 1, vascular lesions. Diabetic patients with lower limb arteries may develop atherosclerosis, plaque formation, lower limb artery narrowing, obstruction, resulting in poor blood supply to the foot. Ischemia may appear as symptoms, including coldness in both lower extremities, legs start to hurt when there is a distance (intermittent claudication), and even legs can be painful when resting. 2. Neuropathy. Neuropathy may cause patients to have decreased sensation in the foot, deformation of the foot, more prone to keratotic tissue, and chronic ulcers. Due to the loss of sensation, patients often do not feel the pain of the ulcer, including pain due to vascular lesions, making the delayed aggravation of the disease. Therefore, the primary prevention of diabetic foot should be brought to the attention of every diabetic patient and treated seriously. First, patients should control blood sugar smoothly, have a basic understanding of what their complications are and to what extent, and actively control the development of complications. This part of the work is done by the patient and the endocrinologist, working together. Secondly, patients themselves need to do the following items, check shoes and socks, socks have no rough stitching, there is no hole, whether shoes fit, will not squeeze the toes; avoid walking barefoot, do not wear shoes without socks; need to wash feet often and dry (between the toes), the water temperature of washing feet should be less than 40 degrees Celsius, you can let the next person to measure the water temperature, do not use the foot bath to heat up too high, hot water bags to warm the feet; cut Toenail care not too short, do not cut the skin; do not use plasters on the feet.
