What lifestyle changes can help manage peripheral arterial disease?

• A. Smoking cessation, regular exercise, and dietary modifications to lower cholesterol.
• B. Increased smoking, sedentary lifestyle.
• C. High-sodium diet with rest.
• D. No lifestyle changes.

Answer: (A)

Lifestyle changes form the foundation of managing peripheral arterial disease because they directly influence the factors that worsen arterial blockages and blood flow. Quitting smoking reduces vasoconstriction and vascular inflammation, slowing progression of atherosclerosis and improving limb perfusion. Regular, structured exercise—often a supervised walking program—helps improve walking distance and leg pain by promoting better blood flow and the development of collateral vessels. Dietary modifications that lower cholesterol address the atherosclerotic process itself, reducing LDL and other risk factors that fuel plaque buildup. Together, these changes not only ease symptoms but also lower cardiovascular risk.

Continuing to smoke or remaining sedentary would worsen arterial disease and its symptoms, while a high-sodium diet with rest doesn’t address the underlying atherosclerosis and can raise blood pressure; doing nothing misses the opportunity to slow progression.
