Just over half a hundred years old Qian manager career is as busy as ever, busy all day, suffering from diabetes for 10 years also did not have time to go to the hospital to see a doctor, just take a little oral medicine, often eat this time forget the next. In the past year, I felt numbness in my feet, and my lower limbs were easily fatigued after walking far away, so I thought I didn’t care about the lack of exercise. During the National Day holiday, I went on a trip with a few friends and felt a little fatigue in my lower limbs while hiking, but I gritted my teeth and insisted in order not to spoil the fun for everyone, and I felt a rare relaxation and was very happy. After returning, I found a blister on my left thumb, so I picked it up myself and it went away with some water, so I didn’t care. A few days later, the left foot became red and swollen and could not wear shoes, but the pain was not severe. As there were many things to deal with after the holiday, I had to take a little anti-inflammatory medicine to deal with it. Unexpectedly, three or two days later there were chills and fever, the temperature reached more than 39 degrees, the emergency sent to the hospital, found that the left foot ulcerated in many places, flowing pus, a large area of skin black necrosis, despite comprehensive treatment, the infection is still difficult to control, continued high fever does not subside, in order to save the life of the doctor recommended high amputation, the patient and family members are reluctant, and then introduced to our hospital vascular treatment to save the limb. There are by no means a few people who have the same experience as Manager Qian. Although we are not strangers to diabetes, not many people know that it causes amputation. Gangrene of the extremity is one of the serious complications of diabetes, and more than 40,000 people in the United States alone have their limbs amputated each year due to diabetic gangrene. Statistics in China, about 20% of patients with diabetes combined with vascular disease of the extremities, due to vascular disease resulting in reduced blood supply to the feet, low resistance, easy to cause infection, the slightest carelessness can occur ulcers, necrosis and serious consequences, especially in the elderly, if combined with serious infection, amputation can save life or a good ending, some patients will die as a result. Therefore, diabetic patients should pay attention to the following points: 1. Pay attention to the early symptoms of limb ischemia Diabetic patients can avoid the disastrous consequences of limb ulceration and necrosis if they are treated early, so they should go to the vascular department regularly to check the blood supply to the limbs in order to detect early limb ischemia. Early symptoms of limb ischemia, such as coldness, numbness, weakness or pain after walking, change in skin color, etc., should be noted. Early and correct diagnosis and treatment is the key to achieve effective treatment, do not miss the opportunity to cause lifelong regret. 2. Avoid limb trauma Diabetic patients may lose their limbs or even their lives because of unsuitable shoes. Always be vigilant to prevent any kind of trauma to the limbs, even if it is insignificant to normal people, skin trauma should be given attention and handled actively and correctly. 3, active treatment of diabetes, stable blood sugar Many diabetic patients lack awareness of the prognosis, can not adhere to the formal treatment, the application of hypoglycemic drugs intermittently, and long-term non-monitoring of blood sugar, making blood sugar unstable. This will easily make the complications of diabetes appear early and serious, and it is difficult to treat the complications when they appear, so controlling diabetes and stabilizing blood sugar is the basis for preventing and treating its complications.
