A properly working immune system identifies foreign substances in the body that might cause illness, such as bacteria and viruses. The immune system then creates antibodies which attack the foreign substances, neutralizing them and keeping the body safe. In people with autoimmune disorders, something goes wrong with this process. For reasons that are not fully understand, the immune system creates antibodies to attack the patient's own tissues.

Symptoms of an autoimmune disorder depend on which tissue is being attacked by the immune system, but common symptoms of autoimmune disease include fever, fatigue, and a general feeling of just not being well. Autoimmune disorders are more common in women than in men, and they may run in families. Autoimmune disorders can affect various parts of the body such as blood vessels, connective tissue, endocrine glands, joints, muscles, red blood cells, skin, and many others.

It is common to have more than one autoimmune disorder at a time. Most are chronic, or life-long illnesses, although they may come and go in flares. Treatment for autoimmune disorders depends on which part of the body is being attacked. For example:

• A type 1 diabetic whose pancreas has been damaged will need insulin.
• A person with Hashimoto's whose thyroid has been damaged will need replacement thyroid hormones.
• Someone with Sjogren's syndrome will need eye drops and mouth rinses to replace tears and saliva.

Many autoimmune disorders of all kinds are treated with immune-suppressing medications, such as corticosteroids (e.g. prednisone) to reduce the effect of the immune system.

Joint problems include bursitis and arthritis. Bursitis is the inflammation of a fluid-filled sac cushion on the outside of a joint, causing symptoms including pain and swelling. Arthritis is the inflammation and damage of a joint due to wear and tear or disease. There are several treatments for arthritis, but if the damage progresses far enough, joint replacement may be necessary. In joint replacement, a metal or plastic implant is surgically placed within the joint to make movement easier.

Bone problems include scoliosis, fractures, and osteoporosis. Scoliosis is a curvature of the spine, making the normally straight spine look like a 'C' or 'S.' It is treated with braces or surgery. Osteoporosis is a disease that causes bones to weaken and break easily. It's most common in women, especially older women. Fully half of all women over 65 have osteoporosis. Fractures are any break in the bone. They can be a simple crack or a severe and complicated shatter. Osteoporosis causes fractures in people who have it, but other causes are trauma (such as a fall) or overuse.

Tendon and ligament problems most often result from injury or overuse. Two good examples are ligament tears and tendonitis. The most common ligament tear is the ACL tear in the knee. This ligament supports and stabilizes the knee and is most often torn during sports activities. Tendonitis happens when a tendon, which connects muscles and bones together, becomes irritated and inflamed. This happens most often in older patients who push their bodies too far, leading to pain and swelling. Treatment for both tendon and ligament problems usually includes rest, ice, and supporting the area to let it heal.

Pain and numbness problems can be caused by overuse, disease, an injury, or a compressed nerve. Lower back pain and carpal tunnel syndrome are two of the most common conditions patients encounter. Lower back pain may be caused by sore muscles that have been overworked, or an injury to the disks separating the vertebrae in the spine. Lower back pain usually goes away on its own within a few days, but it may require medical treatment depending on the cause. Carpal tunnel syndrome occurs when the nerve at the base of the palm becomes trapped or pinched. Symptoms include tingling, pain, numbness, or weakness in the hand. Treatment involves rest and sometimes steroid injections.

Because the musculoskeletal system involves so much of the body, problems here can be incredibly varied in their type and severity. Some musculoskeletal problems will go away on their own or only require rest, while others may require medication, physical therapy, or even surgery.

Professional cosmetic skin treatments exist to treat wrinkles, scars, dark spots, remove excess hair, tone and tighten skin, and otherwise improve the appearance of the skin. They may use lasers, light therapy, chemical peels, microdermabrasion, or many other forms of skin treatment.

Acne occurs when hair follicles become clogged with oil and dead skin cells, most commonly on the face or back. The clogged follicles can then become infected and inflamed. Treatments include antibiotics, anti-inflammatories, and retinoid creams.

Eczema is dry, sensitive skin that causes an itchy red rash, often in response to specific triggers. It is common in childhood but can sometimes last into adulthood. The main treatment involves keeping skin well moisturized.

Dermatitis is the medical name for any kind of skin inflammation or rash. Rashes can happen because of an allergy or contact with an irritating substance. They may be red, itchy, or even painful. They are often treated with antihistamines or moisturizing creams containing cortisone.

Psoriasis is patches of thick, red skin that is covered in silvery scales. It is often itchy and sore. Psoriasis is thought to be caused by an immune disorder, and it runs in families. Psoriasis is not contagious. There is no cure, but there are medicated creams available to treat the symptoms.

Skin growths, including warts and moles, are usually not serious. However, some skin growths should be examined by a doctor to make sure they don't cause problems in the future. Warts are harmless, rough, bumpy growths caused by a viral infection. They occur most often on the hands and feet. Because they are caused by a virus, they are contagious. Moles are brown or black spots that are sometimes raised slightly from the surface of the skin. They happen when clumps of pigment cells form in a cluster instead of spread out. Moles are harmless except that they are more vulnerable to cancer than other parts of the skin. Skin cancer is the most common form of cancer in the United States, and its risk increases with sun exposure and fair skin tone.

Skin issues can be embarrassing or irritating, but most are minor and can be treated without serious problems. Some, however, can be a sign of a more significant issue, so it is important to see a doctor for anything out of the ordinary.
