What is diabetic foot?

“Diabetic foot” is a common problem for diabetic patients. If diabetic patients do not control their blood sugar well, they will develop vascular disease. If the blood vessels are not healthy, they will not be able to supply enough nutrients to the nerves, which will easily lead to neuropathy, especially in the toes and fingers. Symptoms usually start in the toes. It begins to appear and slowly extends upward, and is more severe on the lower limbs than on the upper limbs. Because of neuropathy, the skin is prone to dryness and cracking, and the patient’s sense of pain becomes dull. Patients are prone to bruises or lacerations without realizing it, which can lead to secondary bacterial infections. Coupled with poor blood circulation, tissue hypoxia, and loss of white blood cells. Methods to sterilize, so it is easy to form diabetic foot ulcers.

Why do diabetic feet occur?

Excessive blood sugar can cause inflammation and damage to blood vessel walls, triggering platelet aggregation and leading to atherosclerosis. The diameter of blood vessels becomes increasingly narrow, which can easily cause arterial obstruction in the lower limbs. When a foot is injured, the wound needs good blood circulation to repair the tissue. If the arteries of the lower limbs are narrowed or blocked and blood circulation is poor, the wound will be difficult to repair, and such a small wound may turn into a foot ulcer. If you take superficial wounds lightly and delay medical treatment or follow folk remedies, it may cause the wound to deteriorate to a deeper level, and even cause cellulitis due to bacterial infection, trigger systemic sepsis, and lead to multiple organ failure.

The three major factors causing foot lesions in patients are:

  1. Lower extremity vascular disease
