Hair growth changes on the affected limb are associated with arterial insufficiency.

Hair growth changes on the affected limb are associated with arterial insufficiency.

• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

Reduced arterial blood flow to the limb leads to diminished oxygen and nutrients reaching the hair follicles, causing hair thinning or loss on the affected leg or foot. This hair change is a classic sign of arterial insufficiency seen in peripheral artery disease, and it usually appears alongside other ischemic clues such as cool, pale skin and weak or absent pulses. In contrast, venous problems tend to cause edema and skin changes like hyperpigmentation and ulcers rather than hair loss.
