The dry weather in autumn makes it a relatively easy season for diabetic patients to develop diabetic foot. Diabetic patients should learn to protect their feet in autumn and pay high attention to the prevention and treatment of diabetic foot. Once a diabetic patient becomes ill, he or she must not only strictly monitor blood sugar, but also prevent various complications. Diabetic foot disease, as one of the serious complications of diabetes, must be taken seriously by diabetic patients. Although diabetic foot lesions may sound serious, most amputations caused by diabetic foot can be avoided if early prevention and treatment is done. Often, the early symptoms of diabetic foot are easily overlooked. Auntie Wang from Nanjing Qinhuai District has been suffering from diabetes for more than 20 years. More than a year ago, she felt soreness in her calves when she walked, and then she could continue walking after a rest period, and then she felt soreness in her calves after walking for a period of time. For these symptoms Wang aunt did not pay special attention to, feel that may be because of the age, walking leg is not good is a normal phenomenon. But about a month ago, the back of Wang’s foot appeared red spots, and gradually developed to black toes. She immediately went to the hospital, after examination, Wang Auntie is suffering from diabetic foot. In fact, Ms. Li should have come to the hospital more than a year ago when she felt soreness in her calves, but many clinical patients ignore the early symptoms of diabetic foot and often come to the hospital only when the condition is very serious. As the diabetic foot does not feel like a serious lesion at the beginning of the disease, the patient does not pay attention to it ideologically, and medical care is not in place. Some patients think it is because they are old when they have symptoms such as sore legs and cramps when walking, and some patients mistakenly believe that these symptoms are caused by lumbar disc lesions, without thinking that they are caused by diabetic foot, and some patients have foot skin ulcers, but they still think it is a trivial matter, not knowing that once the ulcers appear in diabetic foot patients, it is often difficult to heal. Finally, to remind the majority of diabetic patients: although diabetes is a lifelong disease, but the complications such as diabetic foot can be prevented, as long as the prevention of health care properly, can completely avoid complications resulting in death and disability. Therefore, when a patient finds out that he or she has diabetes, the patient should apply blood sugar control drugs regularly to bring blood sugar down to normal, and should always care for his or her feet. When there is an abnormal change in the color, temperature sensation and touch of the skin of the foot or some minor trauma, please see a professional physician in time.
