The first fundamental step is monitoring blood glucose; good control of blood glucose levels is essential for the effective management of diabetic foot problems. Secondly, attention must be paid to the protection of the wound. It's crucial to keep the wound clean, perform regular cleaning and disinfection, and when necessary, debride necrotic tissue thoroughly. For instance, if there is a sinus tract or deep ulceration, it is essential to open the wound and ensure drainage, removing all necrotic tissue inside. Thirdly, footwear choice is critical for patients with diabetic foot; it is important to wear shoes that are loose fitting, moderately soft yet firm, and capable of evenly distributing pressure across the footbed. There are shoes specially designed for those with diabetic foot, and these can be custom-made. Other considerations include maintaining good blood pressure control and ensuring adequate nutrition to support wound healing, including sufficient protein intake, which plays a vital role in promoting wound repair.
