Diabetic foot ulcers are open sores or wounds that commonly occur in individuals with diabetes. These ulcers typically develop on the feet due to poor circulation and nerve damage, which can result from high blood sugar levels. If not treated promptly, they can lead to serious infections and complications. Preventing diabetic foot ulcers involves regular foot care, including daily inspections for cuts or blisters, proper footwear, and maintaining good blood sugar control. Early detection and treatment are crucial to avoid severe outcomes, such as amputation in extreme cases.
