What is autoimmune disease

It's been years since my aunt had allergies. She always try to diet and choose the right food to eat but it seems like everything she eat's she'll get allergy. Sometime the allergy will make her throat swollen and it will make her harder to breath. She also did fall two time while she was stretching.

She went to the hospital to get a blood test  but we only knew that it was an autoimmune disease. Well there is so many kind that of autoimmune but we do not know which one. What is the cause of the autoimmune system. I don't really know about autoimmune system but I have done some research on it.

What does your immune system do?
The immune system, which is made up of special cells, proteins, tissues, and organs, defends people against germs and microorganisms every day.  The immune system does a great job of keeping people healthy and preventing infections. But sometimes, problems with the immune system can lead to illness and infection.

Disorders of the immune system can be broken down into four main categories:

• immunodeficiency disorders (primary or acquired)
• autoimmune disorders (in which the body's own immune system attacks its own tissue as foreign matter)
• allergic disorders (in which the immune system overreacts in response to an antigen)
• cancers of the immune system

Well, autoimmune disease happens when your immune system mistakenly attacks your body. A healthy immune system can tell the differences between foreign cells and your own cells but when it comes to an autoimmune system, your immune system misrepresent your body part such as your joints and your skin as a foreign. It releases proteins called as autoantibodies  that attacks your own  healthy cells.

Autoimmune system can affect many parts of your body. There is more then 100 autoimmune disease. There are some symptoms such as fatigue. Fatigue means a person who is extremely tired and exhausted. Not only fatigue but also muscle ache and low fever. Autoimmune disease can also cause redness, heat, pain, and swelling.

Doctor will give you some steroids called Corticosteroids or Glucocorticoids. This is to reduce the immune response to your body. I will be writing more about autoimmune disease in my next blog.
