Overview of Autoimmune Diseases
An autoimmune disease is any disease in which the immune system of the body thinks of its own healthy cells and tissues as foreign, something it should fight and destroy.
Causes and Risk Factors of Autoimmune Diseases
There is no known cause for these diseases, but some factors are known to trigger it. Some of these are bacterial and viral infection, environmental factors such as chemicals and toxins in the surroundings, and even drugs and medications.
There are over 80 kinds of autoimmune diseases, but the most common ones are psoriasis, type 1 diabetes, and rheumatoid arthritis. Other types include systemic lupus erythematosus, multiple sclerosis, as well as pernicious anemia to name a few.
Signs and Symptoms of Autoimmune Diseases
Signs and symptoms of autoimmune diseases vary, of course, depending upon the exact type of autoimmune diseases as well as their location. However, all of them have common signs and symptoms such as:
- Body aches and pains, especially in the joints and muscles.
These flare up when the disease is at its worst, but it typically tapers off and goes away during remission.
