Inadequate blood supply to a tissue.
A deficient blood supply to a part of the body.
Bloodlessness of a part of the body, due to contraction, spasm, constriction or blocking (by embolus or by thrombus) of the arteries: for example, of the heart.
Inadequate blood flow to a particular organ or tissue, often resulting from vascular diseases like atherosclerosis. It can also arise from injuries, a blood vessel constriction due to muscle spasm in its wall, or poor blood circulation because of ineffective heart pumping. The symptoms vary based on the affected region.
Therapy might involve vasodilator medications to expand the blood vessels. For more critical conditions, procedures like angioplasty or a bypass surgery could be considered.
