A: Autoimmune disorders



Autoimmune disorders:  as per MedlinePlus — An autoimmune disorder is a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue. There are more than 80 different types of autoimmune disorders.

Explained a little bit more:

Normally the immune system’s white blood cells help protect the body from harmful substances, called antigens. Examples of antigens include bacteria, viruses, toxins, cancer cells, and blood or tissues from another person or species. The immune system produces antibodies that destroy these harmful substances.

In patients with an autoimmune disorder, the immune system can’t tell the difference between healthy body tissue and antigens. The result is an immune response that destroys normal body tissues. This response is a hypersensitivity response similar to the response in allergic conditions.

In allergies, the immune system reacts to an outside substance that it normally would ignore. With autoimmune disorders, the immune system reacts to normal body tissues that it would normally ignore.

What causes the immune system to no longer tell the difference between healthy body tissues and antigens is unknown. One theory is that some microorganisms (such as bacteria or viruses) or drugs may trigger some of these changes, especially in people who have genes that make them more likely to get autoimmune disorders.

An autoimmune disorder may result in:

  • The destruction of one or more types of body tissue
  • Abnormal growth of an organ
  • Changes in organ function

LUCKY ME!!  I have won the genetic lottery!!  And as of today, they still have no clue which of the many autoimmune disorders I have…

    • Jackie. Nothing really changed. Since I don’t have a specific diagnosis other than fibro, they put me under the umbrella of “autoimmune disorder” because my blood work indicates some sort of autoimmune process, but nothing specific. Hope you are doing ok!!

  1. Well at least you are investigating your own health, which is more than many people do. Perhaps your blog will help someone else in a similar situation. I am stopping by from the A to Z Challenge, and maybe I will come back again.

Tell me what you think
