For prevention of diabetic foot ulcers, which strategy is emphasized?

• A. Lipid control
• B. Tight glycemic control
• C. Exercise only
• D. Blood pressure control only

Answer: (B)

Tight glycemic control is the most emphasized strategy for preventing diabetic foot ulcers because chronic high blood glucose drives neuropathy and impairs wound healing, which are the primary pathways leading to ulcers. When glucose is well controlled, neuropathy progresses more slowly, protective sensation in the feet is better preserved, and immune function plus tissue repair improve, all of which reduce the risk of developing ulcers. Other factors like exercise, lipid management, and blood pressure control support overall cardiovascular and vascular health and can aid foot health, but they do not have as direct an impact on ulcer prevention as maintaining near-normal glucose levels. Regular foot care and proper footwear remain important adjuncts, but the key preventive impact comes from tight glycemic control.
