Diabetic foot can potentially be cured, and it can improve, but it depends on the specific circumstances. Diabetic foot varies in severity and is classified into different levels. In medical terms, it is classified based on its appearance, and different classifications have different prognoses. Even within the same classification, factors like the patient's vascular condition, baseline nutritional status, age, duration of diabetes, and many other factors can influence whether diabetic foot can be cured. In clinical practice, there are many diabetic foot patients who, after comprehensive treatment, achieve complete wound healing. Therefore, whether diabetic foot can be cured depends on many factors.
