Understanding Auto Immune disorders
Who understands auto immune disorders and how they affects us and our loved ones? Here is a brief overview of what it is and a link if you want to research correct information further.
When an intruder invades your body—like a cold virus or bacteria on a thorn that pricks your skin—your immune system protects you. It tries to identify, kill, and eliminate the invaders that might hurt you. But sometimes problems with your immune system cause it to mistake your body’s own healthy cells as invaders and then repeatedly attacks them. This is called an autoimmune disease. (“Autoimmune” means immunity against the self.)
Autoimmune diseases can affect almost any part of the body, including the heart, brain, nerves, muscles, skin, eyes, joints, lungs, kidneys, glands, the digestive tract, and blood vessels. The classic sign of an autoimmune disease is inflammation, which can cause redness, heat, pain, and swelling. How an autoimmune disease affects you depends on what part of the body is targeted. If the disease affects the joints, as in rheumatoid arthritis, you might have joint pain, stiffness, and loss of function. If it affects the thyroid, as in Graves’ disease and thyroiditis, it might cause tiredness, weight gain, and muscle aches. If it attacks the skin, as it does in scleroderma/systemic sclerosis, vitiligo, and systemic lupus erythematosus (SLE), it can cause rashes, blisters, and color changes.
Many autoimmune diseases don’t restrict themselves to one part of the body. For example, SLE can affect the skin, joints, kidneys, heart, nerves, blood vessels, and more. Type 1 diabetes can affect your glands, eyes, kidneys, muscles, and more.
Acquired immune system. The part of the immune system that develops as a person grows. It employs antibodies and immune cells to fight harmful substances.
Antibody. A special protein produced by the body’s immune system that recognizes and helps fight infectious agents and other foreign substances that invade the body.
Antigen. A foreign substance that triggers the production of antibodies when it is introduced into the body.
Autoimmune disease. A disease that results when the immune system mistakenly attacks the body’s own tissues.
Corticosteroids. Potent anti-inflammatory hormones that are made naturally in the body or synthetically (man-made) for use as drugs. They are also called glucocorticoids. The most commonly prescribed drug of this type is prednisone.
Diabetes, type 1. A condition in which the immune system destroys insulin-producing cells of the pancreas, making it impossible for the body to use glucose (blood sugar) for energy. Type 1 diabetes usually occurs in children and young adults.
Graves’ disease. An autoimmune disease of the thyroid gland that results in the overproduction of thyroid hormone. This causes such symptoms as nervousness, heat intolerance, heart palpitations, and unexplained weight loss.
Immune system. A complex network of specialized cells and organs that work together to defend the body against attacks by foreign invaders, such as bacteria and viruses.
Thyroiditis. An inflammation of the thyroid gland that causes the gland to become underactive. This results in symptoms such as fatigue, weakness, weight gain, cold intolerance, and muscle aches.
Vitiligo. A disorder in which the immune system destroys pigment-making cells called melanocytes. This results in white patches of skin on different parts of the body.
The National Institutes of Health (NIH)—The Nation’s Medical Research Agency—includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. It is the primary Federal agency for conducting and supporting basic, clinical, and translational medical research, and it investigates the causes, treatments, and cures for both common and rare diseases.
