Ischemia

Ischemia refers to the reduced blood flow to a part of the body, often leading to a shortage of oxygen and nutrients needed for cellular function. This condition can occur in various organs, most commonly the heart and brain. When blood flow is restricted, it can cause pain, dysfunction, or even tissue damage. Common causes include blocked arteries due to plaque buildup, blood clots, or narrow vessels. Treatment aims to restore blood flow, which may involve medications, lifestyle changes, or procedures like angioplasty or surgery, depending on the severity and location of the ischemia.
