Ischemic conditions occur when blood flow to a part of the body is restricted or reduced, leading to a shortage of oxygen and nutrients. This can happen due to blockages in blood vessels, often caused by atherosclerosis, where fatty deposits build up in the arteries. Common examples include ischemic heart disease and stroke. These conditions can result in tissue damage and organ dysfunction if not addressed promptly. Symptoms may vary depending on the affected area but can include chest pain, weakness, or numbness. Early diagnosis and treatment are crucial to prevent serious complications and improve outcomes.
