Diabetic ulcers are sores or wounds that commonly occur on the feet of individuals with diabetes. These ulcers develop due to a combination of factors, including poor circulation, nerve damage, and high blood sugar levels. When the skin is injured, it may not heal properly, leading to the formation of ulcers. If left untreated, diabetic ulcers can become infected and may lead to serious complications, including amputation. Proper foot care, regular check-ups, and managing blood sugar levels are essential for preventing these ulcers and promoting healing in those who develop them.
