There are many such diabetic patients who have to recover after the appearance of a wound, which does not heal for a long time. Looking at the wounds that are getting worse day by day, we are more worried about what will happen if they continue to develop. First, blood sugar may not come down. Diabetic patients’ blood sugar itself is high, and after the wound infection, the body goes through a series of complex changes, producing a stress response that will in turn affect blood sugar. Second, more healthy tissue is damaged. As long as the infection cannot be controlled, the germs will continue to erode the healthy tissues, without stopping at all times. Some patients develop especially fast, just a toe infection at the beginning, a few days to spread to the entire foot or even quickly spread to the legs, especially terrible. Third, it causes sepsis. When the wound infection is aggravated, a large amount of toxins harmful to the body will be produced, and when these toxins are absorbed by the body in large quantities, it will trigger a systemic reaction and an increased risk of sepsis. Fourth, sudden cardiovascular and cerebrovascular events. Many diabetic foot patients are not in good health, such as having mild or severe cardiovascular problems, in these cases, according to the statistics of our center, the chance of sudden cardiovascular and cerebrovascular events will increase. V. Life threatening. Many of the conditions mentioned above may lead to life-threatening conditions for patients, which is a situation we do not want to see. There are also inappropriate treatments, such as lower limb vascular interventions and amputations, which carry a high risk of life.
