how autoimmune diseases attack the body's defenses?
428216
Autoimmune diseases result from a failure of the body's own defenses against disease. The immune system loses its ability to tell the difference between foreign materials and its own cells. So the body starts attacking its own organs and tissues.

Autoimmune hepatitis is a disease in which the body's own immune system attacks the liver and causes it to become inflamed. The disease is chronic, meaning it lasts many years. If untreated, it can lead to cirrhosis and liver failure.

Lupus is a long-term autoimmune disease in which the body's immune system becomes hyperactive and attacks normal, healthy tissue. Symptoms include inflammation, swelling, and damage to the joints, skin, kidneys, blood, heart, and lungs.

“In autoimmunity, there is a different type of T-cell involved than in allergies. In an autoimmune response, tissue destruction occurs. With allergies, the immune system overreacts to harmless allergens. Interestingly, this is the same type of response that expels viruses, parasites, and bacteria from the body.”

Autoimmune diseases do not cause sepsis, but people with certain types of autoimmune diseases are at higher risk of developing infections, which can trigger sepsis. As well, medications that may be used to treat some autoimmune disorders can weaken your immune system, making it easier for you to develop an infection.

Rheumatoid arthritis (RA) is an autoimmune disease that causes pain and swelling of the joints. The normal role of your body's immune system is to fight off infections to keep you healthy. In an autoimmune disease, your immune system starts attacking your own healthy tissues.

Some common diseases that are generally considered autoimmune include celiac disease, diabetes mellitus type 1, Graves' disease, inflammatory bowel disease, multiple sclerosis, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus. The diagnosis can be difficult to determine.

Immune system disorders cause abnormally low activity or over activity of the immune system. In cases of immune system over activity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections.

Stay on the safe side and avoid use. "Auto-immune diseases" such as multiple sclerosis (MS), lupus (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), or other conditions: Chaga might cause the immune system to become more active. This could increase the symptoms of auto-immune diseases.

When your immune system fails to respond adequately to infection, it's called an immunodeficiency. People may also suffer from the opposite condition, an overactive immune system that attacks healthy cells as though they were foreign bodies, and that is called an autoimmune response.

In skin suffering from an autoimmune blistering disease, your body's immune system mistakes normal skin tissue for something it needs to fight off, and then attacks this healthy skin tissue. This causes blisters to form.

Immune-mediated diseases are conditions which result from abnormal activity of the body's immune system. The immune system may over-react or start attacking the body. Autoimmune diseases are a subset of immune-mediated diseases.

The exact cause of autoimmune disorders is unknown. One theory is that some microorganisms (such as bacteria or viruses) or drugs may trigger changes that confuse the immune system. This may happen more often in people who have genes that make them more prone to autoimmune disorders.

Lupus is a chronic (long-term) disease that can cause inflammation and pain in any part of your body. It's an autoimmune disease, which means that your immune system — the body system that usually fights infections — attacks healthy tissue instead. Lupus most commonly affects your: Skin.

However, while lupus may cause the immune system to attack multiple parts of the body, including the skin, joints, and organs, psoriasis is typically limited to the skin, fingernails, and toenails. People with psoriatic arthritis can also have symptoms in their joints.

Immunologic and Autoimmune Lung Disease With an autoimmune disease, a person's own immune system attacks the lungs, causing inflammation and scarring that can impair lung function and breathing. Rheumatoid arthritis may lead to a group of lung conditions categorized as rheumatoid lung disease.
