Frequently asked question: What is Graves' disease?

Graves' disease is an auto-immune disease. This means that there is a disruption in your immune system. Your immune system protects you from intruders, such as bacteria and viruses, so that you do not get sick. It is a very intelligent system that can recognize, attack and deactivate foreign substances that enter your body. When this happens, you will often have fever, swelling, pain and redness: the signs of an infection. Sometimes this response is intense, and sometimes you hardly notice it. If you have an auto-immune disease, your immune system attacks your own tissues, just as if they were foreign substances. With Graves' disease, that is your TSH receptor. It is not clear why the immune system does this.
