what do diabetic ulcers look like

Diabetic ulcers typically present as open sores on the skin surface, which can be red, yellow, or black with irregular edges. They often occur on the toes, soles, or heels and may be accompanied by pain, signs of infection, or an unpleasant odor.

Examining the ulcers more closely, their appearance varies based on the severity and presence of infection. Initially, ulcers may be small, red or pink with well-defined edges. As the condition advances, they may enlarge and change color to yellow or brown, possibly due to the presence of necrotic tissue. In severe cases, ulcers can become deep, penetrating into muscles or bones, and their color may turn black, indicating dead tissue. Additionally, if an ulcer is infected, there may be pus discharge, with surrounding skin becoming red, swollen, and painful.

Preventing ulcers is vital for individuals with diabetes. Maintaining optimal blood glucose control, regularly inspecting the feet, wearing proper footwear and socks, and avoiding going barefoot are effective preventive strategies. If signs of ulcers are detected, prompt medical attention is essential, and it is crucial to follow the physician's treatment recommendations rather than attempting self-treatment or ignoring the issue.
