Angiopathy refers to a disease or disorder affecting blood vessels. It can involve any type of blood vessel, including arteries, veins, and capillaries. Angiopathy is often used as a general term to describe various conditions that cause damage to the blood vessels, such as atherosclerosis (hardening and narrowing of the arteries), diabetic retinopathy (damage to the blood vessels in the eye), or Raynaud's disease (a condition that causes certain areas of the body to feel numb due to decreased blood flow). The specific meaning of angiopathy depends on the context and which type of blood vessel is affected.
