what is ischemia

Ischemia is a condition where blood flow, and thus oxygen, is restricted or reduced in a part of the body. It can occur in various parts of the body, including the heart, brain, legs, and intestines. Ischemia is usually caused by a build-up or blockage in the arteries, which can be due to atherosclerosis, where plaque collects in the arteries. Symptoms of ischemia depend on where it occurs in the body, but can include chest pain, severe pain in the legs, severe belly pain, and blood in the stool. Some people may have silent ischemia, where they have ischemia but no pain or other symptoms. Ischemia can lead to life-threatening problems like a heart attack or stroke, so it is important to seek medical help right away if you suspect you have it. Treatment for ischemia involves improving blood flow to the affected area, which may include medications, procedures to open blocked arteries, or bypass surgery. Making heart-healthy lifestyle choices is also important in treating and preventing ischemia.
