Autoimmune refers to a group of diseases where the immune system, which normally protects the body from infections, mistakenly attacks healthy cells. This happens because the body’s defense system fails to distinguish between foreign invaders and its own tissues. As a result, the immune response can cause inflammation and damage to various organs and systems in the body.
Understanding autoimmune conditions is essential for health because they can lead to significant symptoms and complications. Many people with autoimmune diseases experience chronic pain, fatigue, and other health issues that can affect their daily lives. Early diagnosis and management can help improve quality of life and prevent further damage to the body.
The basic function of the immune system is to identify and eliminate harmful substances like bacteria and viruses. In autoimmune diseases, this function is disrupted, leading to an inappropriate response against the body's own cells. This can result in conditions affecting different parts of the body, such as the joints, skin, and organs, depending on which cells are misidentified as threats.
Recognizing autoimmune conditions is important, as they can vary widely in their symptoms and severity. While some people may have mild symptoms, others may face serious health challenges. Awareness of these diseases can encourage individuals to seek medical advice when needed.
