Diabetic wounds are difficult to heal because of local microangiopathy due to long-term elevated blood glucose, and abnormal neurotropism.
In clinical practice, some diabetic patients come to the initial consultation because their wounds have not healed for a long time after a minor injury to a part of the body, and the doctor recommends checking the blood glucose and finds that it is elevated to meet the criteria for diagnosing diabetes.
After a traumatic injury in a diabetic patient, it is easy to cause a wound that does not heal easily because of the patient’s long-term elevated blood glucose combined with vascular and neurological complications, resulting in microangiopathy, impaired microcirculation, and local cutaneous neurotropic disorders that affect the local blood supply to the wound. The lack of oxygen and nutrients needed for local wound healing, and the wound does not heal well in a timely manner.
This condition first requires good control of blood glucose, trying to adjust it to normal levels in a short period of time. It is also important to keep the wound clean and change the medication regularly to prevent infection. You can also improve the local blood supply and promote wound healing with infrared irradiation, oral or intravenous circulation-improving drugs. In reality, if you encounter a wound that does not heal for a long time after a trauma, you must remember to check your blood sugar to rule out whether you already have diabetes.
