Iskemiä

Iskemiä, also known as ischemia, is a medical condition characterized by a reduced blood supply to a tissue or organ. This reduction in blood flow can lead to a deficiency of oxygen and nutrients, which can cause tissue damage or death. Iskemiä can occur in various parts of the body, including the heart, brain, and limbs.

The most common cause of iskemiä is atherosclerosis, a condition in which fatty deposits build up in the arteries, narrowing them and reducing blood flow. Other causes include blood clots, spasm of blood vessels, and external compression of arteries. Iskemiä can be acute, occurring suddenly and causing immediate symptoms, or chronic, developing gradually over time.

Symptoms of iskemiä vary depending on the affected area. In the heart, it can cause chest pain, shortness of breath, and nausea. In the brain, it can lead to stroke-like symptoms such as weakness, numbness, or difficulty speaking. In the limbs, it can cause pain, cramping, and weakness.

Treatment for iskemiä depends on the cause and severity of the condition. It may include lifestyle changes such as diet and exercise, medications to manage underlying conditions, or procedures to improve blood flow, such as angioplasty or bypass surgery. In severe cases, organ transplantation may be necessary. Early diagnosis and treatment are crucial to prevent permanent damage or death of the affected tissue.
