What is Autoimmune Diseases?
Autoimmune disease is a condition in which your immune system mistakenly attacks your body
The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them. The immune system can tell the difference between foreign cells and your own cells.
In an autoimmune disease, the immune system mistakes part of your body like your joints or skin, as foreign. It releases auto-antibodies (protein) that attack healthy cells. Some autoimmune diseases target only one organ.
Immune system disorders cause abnormally low activity or over activity of the immune system. In cases of immune system over activity, the body attacks and damages it’s own tissues (Autoimmune diseases). Immune deficiency diseases decrease the body’s ability to fight invaders, causing vulnerability to infections.
In response to an unknown trigger, the immune system may begin producing antibodies that instead of fighting infections, attack the body’s own tissues. Treatment for autoimmune diseases generally focuses on reducing immune system activity.
The left blood vessel is normal and contains a normal blood cell composition (especially red blood cells). In the right blood vessel there is an intruder present to which the immune system responds: there are various immune system cells that attack the intruder. Also, the blood vessel allows cells to ‘escape’ so that the intruder can also be attacked outside the blood vessel. There is redness (because of the red blood cells that escape) and sometimes a swelling (due to the amount of fluid that spills from the blood vessel). In case of autoimmune disease, this happens too without a reason!
Researchers don’t know exactly what causes autoimmune diseases. Diet, infections and exposure to chemicals might be involved.
Autoimmune diseases are Systemic lupus erythematosus (Lupus), Reumatoid arthritis, Type I Diabetes mellitus, Psoriasis dan Hashimoto’s Thyroiditis
The early symptoms of many autoimmune diseases are very similar such as fatigue, muscle aches, swelling, trouble concentrating, hair loss and skin rashes. Often symptoms come and go over time.
