As the weather gets colder, some patients may have sunken legs, sore legs, leg pain and cold legs and feet, which can be easily confused with “cold legs” attacks. In fact, for patients with diabetic foot, this condition is mainly caused by cold aggravating foot blood circulation disorders, should not be brutally treated with hot water, electric heating and other soaking and baking methods. Pay attention to the small details of life, it is likely to help patients escape. Feet are an important part of the human body, and normal walking cannot be done without a healthy pair of feet. The standard for healthy feet is to have good blood circulation, good sensation to the outside world, as well as good function and form. But diabetes destroys the blood vessels, nerves and bones of the foot, affecting the lives of patients and putting the feet at risk. Statistics show that diabetes has become the number one cause of amputation in many countries, with many patients losing their feet, having high level amputations, and never being able to walk again, or even losing their lives. In addition, treatment for diabetic foot is very expensive, difficult, and takes a long time. In order to avoid the occurrence of “people and money”, diabetic patients should protect their feet, identify high-risk feet as early as possible, and carry out active prevention and treatment. Diabetic foot starts from grade 0 It is generally believed that diabetic foot is a foot infection, ulcer and/or deep tissue destruction associated with local nerve abnormalities and lower extremity vasculopathy, by which time treatment is already somewhat late, quite costly and not very effective. The Wagner grading method, which is widely used in clinical practice, classifies diabetic foot into 6 grades according to nerve and vascular lesions, depth of ulceration and presence of infection, among which grade 0 refers to a foot at risk of foot ulceration, but without ulceration at the extremity. In other words, there is no open lesion on the skin, which often shows insufficient blood supply to the extremity, cold skin, purple-brown color, numbness, dull sensation or loss of sensation, toe or foot deformity, etc. This means that a grade 0 foot is a foot that is at risk of developing a foot ulcer, but currently has no ulcers, also known as a high-risk foot. is a grade 0 foot a diabetic foot? The answer is yes. Prevention is far more effective than treatment when intervention begins at grade 0. The early symptoms of a diabetic foot vary depending on the lesion. Patients with predominantly vascular lesions of the diabetic foot may exhibit symptoms such as cold and chilly feet, pale or bruised skin, edema, lower leg cramps, pain, and increased pain when walking (i.e., intermittent claudication), which are often the early and most common clinical manifestations of peripheral arterial disease of the lower extremities. Once a foot wound appears, it is difficult to heal for a long time. Patients with a predominantly neuropathic diabetic foot present mainly with numbness, burning, pins and needles sensation or loss of normal sensation. Patients with such lesions have a reduced ability to perceive external stimuli or trauma, so they are insensitive to water temperature, external pressure, and external stimuli, so that diabetic foot patients are often aggravated by burns, extrusions, trauma, and other factors, which eventually lead to incurable ulcers. If a tiny wound is not detected in time, the wound may continue to expand and become infected, which may eventually lead to very serious consequences. Although the consequences of diabetic foot are terrible, but in general it is still preventable and treatable, and there are many patients who can live a very happy life with the disease for a long time. I hope you will make it a good habit to check your feet every day. No matter how cold the weather is, the temperature of the foot soak water for diabetic patients should not exceed the body surface temperature, to about 35 degrees Celsius is appropriate, soak for about 15 minutes can be. Some patients always feel that the foot soak water is cold, in fact, not the water is cold, but their own foot blood supply problems, can not just increase the temperature of the water; wipe feet to choose soft cotton towels, pay attention to the timely replacement of old rough towels, wipe the feet at the same time pay attention to observe the skin has no red, swollen, cracked, blisters, crush injuries, ringworm, scratches and deformation of the toes. If direct observation is inconvenient, you can use a small mirror, or ask family members or caregivers to help check. For patients with dry foot skin, it is recommended to apply a little moisturizing lotion to prevent skin cracking, and when applying it, pay attention to avoid the toe seam which is not easy to breathe; a few patients whose feet are prone to sweating can increase the frequency of foot washing appropriately. When the weather is cold, you must pay attention to the warmth of the feet and wear appropriate shoes. In addition, a special reminder, each time before wearing shoes to pay attention to observe the internal situation of the shoes, to see if there is no small gravel or pegs and other things, the easiest way is to wear before knocking by hand, to pour out everything inside.
