Takayasu arteritis is a rare inflammatory disease that primarily affects the large blood vessels, particularly the aorta and its main branches. It is most commonly seen in young women, typically under the age of 40. The inflammation can lead to narrowing or blockage of the arteries, which may result in reduced blood flow to various organs. Symptoms of Takayasu arteritis can include fatigue, fever, weight loss, and pain in the arms or legs. Diagnosis often involves imaging studies, such as MRI or CT scans, to assess blood vessel involvement. Treatment usually includes medications to reduce inflammation and manage symptoms.
