What is Autoimmune Disease?

Autoimmune Disease

Quick Answer

An autoimmune disease occurs when the body's immune system mistakenly attacks its own healthy cells. This can lead to inflammation and damage in various parts of the body, resulting in a variety of symptoms and health issues.

Overview

Autoimmune diseases happen when the immune system, which is supposed to protect the body from illness, turns against it instead. This means that the body attacks its own tissues, thinking they are harmful invaders. There are many different types of autoimmune diseases, affecting various organs and systems, and they can range from mild to severe. One common example of an autoimmune disease is rheumatoid arthritis, which primarily affects the joints. In this condition, the immune system attacks the lining of the joints, causing pain, swelling, and stiffness. Over time, this can lead to joint damage and reduced mobility, significantly impacting a person's quality of life. Understanding autoimmune diseases is important because they can lead to chronic health issues and require long-term management. Early diagnosis and treatment can help manage symptoms and improve the overall well-being of individuals affected by these conditions. Awareness of autoimmune diseases also helps in research and finding better treatments, as many people may not realize they have one.
