Autoimmune diseases

Rangkaian penyakit Guillain Barre Syndrome...

Guillain-Barre (GEE-yahn bah-RAY) syndromeThe immune system attacks the nerves that connect your brain and spinal cord with the rest of your body. Damage to the nerves makes it hard for them to transmit signals. As a result, the muscles have trouble responding to the brain.

What are autoimmune diseases?


Our bodies have an immune system, which is a complex network of special cells and organs that defends the body from germs and other foreign invaders. At the core of the immune system is the ability to tell the difference between self and nonself: what's you and what's foreign. A flaw can make the body unable to tell the difference between self and nonself. When this happens, the body makes autoantibodies (AW-toh-AN-teye-bah-deez) that attack normal cells by mistake. At the same time special cells called regulatory T cells fail to do their job of keeping the immune system in line. The result is a misguided attack on your own body. This causes the damage we know as autoimmune disease. The body parts that are affected depend on the type of autoimmune disease. There are more than 80 known types.

How common are autoimmune diseases?

Overall, autoimmune diseases are common, affecting more than 23.5 million Americans. They are a leading cause of death and disability. Yet some autoimmune diseases are rare, while others, such as Hashimoto's disease, affect many people.


Who gets autoimmune diseaseas

Autoimmune diseases can affect anyone. Yet certain people are at greater risk, including:

  • Women of childbearing age — More women than men have autoimmune diseases, which often start during their childbearing years.
  • People with a family history — Some autoimmune diseases run in families, such as lupus and multiple sclerosis. It is also common for different types of autoimmune diseases to affect different members of a single family. Inheriting certain genes can make it more likely to get an autoimmune disease. But a combination of genes and other factors may trigger the disease to start.
  • People who are around certain things in the environment — Certain events or environmental exposures may cause some autoimmune diseases, or make them worse. Sunlight, chemicals called solvents, and viral and bacterial infections are linked to many autoimmune diseases.
  • People of certain races or ethnic backgrounds — Some autoimmune diseases are more common or more severely affect certain groups of people more than others. For instance, type 1 diabetes is more common in white people. Lupus is most severe for African-American and Hispanic people.

The diseases listed here either are more common in women than men or affect many women and men. They are listed in A-to-Z order.

What autoimmune diseases affect women, and what are their symptoms?

Although each disease is unique, many share hallmark symptoms, such as fatigue, dizziness, and low-grade fever. For many autoimmune diseases, symptoms come and go, or can be mild sometimes and severe at others. When symptoms go away for a while, it's called remission. Flares are the sudden and severe onset of symptoms.

  1. Hello,

    Thank you for sharing such relevant topic with us. Autoantibodies are soluble molecules present in biological fluids such as blood, colostrum, saliva, cerebrospinal fluids and the intestinal lumen, they are mediators of humoral immune responses and protect against infections...
