Which medical term indicates an inadequate blood supply causing pain in the extremities?

The term that indicates an inadequate blood supply causing pain in the extremities is "claudication." This condition typically manifests during physical activities such as walking or exercising, where the muscles in the legs receive insufficient oxygenated blood due to narrowed or blocked arteries. As a result, patients experience pain, discomfort, or cramping in the legs or buttocks that usually eases with rest.

This understanding is essential for recognizing the symptoms associated with peripheral artery disease (PAD), which is often the underlying cause of claudication. Unlike other terms listed, such as hypertension (high blood pressure), arrhythmia (irregular heartbeat), and bradycardia (slower than normal heart rate), claudication specifically relates to the consequences of poor circulation in the limbs and is often a key indicator of vascular health.
