How long does a smoking cessation programme take to work for peripheral arterial disease?

Stopping smoking removes repeated exposure to substances that narrow blood vessels and reduce oxygen delivery. You may notice changes in cravings, breathing or stamina before leg symptoms improve, and some people do not feel an immediate difference. The programme does not reverse established artery narrowing by itself. It supports treatment by reducing further vascular stress and making other care easier to follow.

Use the agreed quit plan, including coaching, nicotine replacement or prescribed medicines if offered. Record cravings and walking symptoms so your clinician can adjust support. Keep taking prescribed vascular medicines and follow advice about walking activity; do not stop them because you have quit. A follow-up can review smoking status, leg pain, foot health and cardiovascular risk.

Seek urgent medical help for sudden severe leg pain, a cold or pale foot, new numbness or weakness, or a wound that becomes rapidly worse. Contact your clinician promptly if walking pain is increasing, pain occurs at rest, or a foot wound is not healing. These changes need assessment regardless of how long you have been smoke-free.

Ask which quit support suits your nicotine use, when your leg circulation should be reviewed, and which symptoms should trigger same-day care. You can also ask how walking therapy, medicines and foot checks fit alongside the programme.
