Types of Autoimmune Disorders

Your body uses the immunity function to protect it from various diseases. For example, when an infection occurs in any part of the body antibodies are produced to fight against the antigens. But in some people when the antibodies destroy the antigens it will also cause damage to your body by mistake. This condition is known as autoimmune disorder. It can affect any part of your body. Here is a list the common autoimmune disorders that have been observed in humans:

Autoimmune Disorders Affecting Circulatory System
Vasculitis and hemolytic anemia are the two Autoimmune Disorders affecting the circulatory system. Vasculitis is the infection of the blood vessels that causes pain in the abdomen, loss of weight, difficulty in breathing, skin rashes and nerve damage. Hemolytic anemia is characterized by destruction of red blood cells causing symptoms similar to anemia. This includes extreme fatigue and weakness.

Autoimmune Disorders Affecting Nervous System
The Autoimmune Disorders affecting the nervous system include myasthenia gravis and multiple sclerosis. Multiple Sclerosis is a condition that affects the outer covering of a neuron (nerve cell) called the myelin sheath. Myelin sheath is responsible for the transmission of signals from the brain to different parts of the body and vice versa. But, in multiple sclerosis the transmission of the signals does not occur due to the absence of myelin sheath. The symptoms include muscle weakness and spasm, and problems with vision.

Autoimmune Disorders Affecting Digestive System
Celiac disease, type 1 diabetes mellitus, pernicious anemia and Addison's disease are the main auto immune disorders affecting the digestive system. Celiac disease causes damage to villi present in the small intestine. The damage is done by gluten present in some grains, which will cause abdominal pain, indigestion, diarrhea, constipation and even behavioral changes. Type 1 diabetes mellitus affects the pancreas, reducing the amount of insulin produced. Pernicious anemia causes mal-absorption of vitamin B12, resulting in its deficiency. Addison's disease affects the adrenal gland and results in reduction in hormone levels. It can cause fatigue, diarrhea, and darkening of the skin.

Autoimmune Disorders Affecting Muscular System
The common autoimmune disorder affecting the muscular system is dermatomyositis. It may cause difficulty in breathing and swallowing, muscle weakness and skin rash.

Autoimmune Disorders Affecting Thyroid Glands
Graves disease, one of the Autoimmune Disorders affecting the thyroid gland causes increased production of thyroid hormones known as hyperthyroidism. It may cause tremor, lose of weight and increase in heart rate. On the other hand, Hashimoto's thyroiditis causes hypothyroidism resulting in increase in weight and cold intolerance.

Autoimmune Disorders Affecting Skin
Bullous pemphigoid affects the skin causing formation of blisters. These lesions may be itchy and red.
