- 10 hilariously insightful foreign words. An overactive immune system, or autoimmune disorder, is when the immune system attacks and destroys healthy body tissue rather than the antigens it is supposed to target. Tissue damage, organ damage and changes in organ function are some of the results of autoimmune diseases. diagram showing different types of white blood cells, an important part of the immune system. Reishi mushrooms are one type of alternative treatment for an overactive immune system. Rheumatoid arthritis is one commonly known result of an overactive immune system.

Addison's Disease The immune system defends the body against infections and certain other diseases. It is made up of different organs, cells, and proteins known as antibodies. It identifies, attacks, and destroys germs and other foreign substances. Sometimes the immune system makes a mistake and attacks the body's own tissues or organs. This is called autoimmunity. One example of an autoimmune disease is type 1 diabetes, in which the immune system destroys the cells in the pancreas that produce insulin.

Human Physiology/The Immune System When the immune system does not function properly, it leaves the body susceptible to an array of diseases. Allergies and hypersensitivity to certain substances are considered immune system disorders. In addition, the immune system plays a role in the rejection process of transplanted organs or tissue.he Immune System-Click to Enlarge. The organs involved with the immune system are called the lymphoid organs, which affect growth, development, and the release of lymphocytes (a certain type of white blood cell).

Glossary: what does this word mean? Knowledge center. Hypothyroidism, also known as underactive thyroid, is a condition where the thyroid gland does not create enough of a thyroid hormone called thyroxine. Thyroid hormones regulate the way in which the body uses energy-metabolism-and without enough thyroxine many of the body's functions slow down.

- The immune system and the inflammatory response. Many experts now see inflammation as arising from an immune system response that’s out of control. When you catch a cold or sprain your ankle, your immune system switches into gear. Infection or injury trigger a chain of events called the inflammatory cascade. The familiar signs of normal inflammation — heat, pain, redness, and swelling — are the first signals that your immune system is being called into action.

Inflammation and the Immune System: 50 Guides, Articles, Videos, and Other Resources on How Inflammation Impacts Immune Health Inflammation and the Immune System: 50 Guides, Articles, Videos, and Other Resources on How Inflammation Impacts Immune Health. Inflammation involves white blood cells and their substances protecting the body from infection and against invaders like bacteria and viruses. As such, inflammation is an immune system response that helps defend the body. But, when the immune system prompts inflammation to occur even though invaders are not putting the body at risk, the immune system attacks normal tissues as though they are infected or abnormal, and the person develops an autoimmune disease.

Immune system The immune system is a system of many biological structures and processes within an organism that protects against disease.To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue.he main response of the immune system to tumors is to destroy the abnormal cells using killer T cells, sometimes with the assistance of helper T cells. Tumor antigens are presented on MHC class I molecules in a similar way to viral antigens. This allows killer T cells to recognize the tumor cell as abnormal.

- Autoimmune Diseases. There are a variety of autoimmune diseases that weaken the immune system. An autoimmune disease is the result of the body attacking itself. Some cells within the body become hyperactive and don't function as they should.hen the kidneys are not functioning properly due to kidney disease, more toxins circulate within the blood. The excess toxins affect the immune system, making a person more tired and sluggish. A person with kidney disease will become sick more often because the immune system is weakened.

The symptoms of inflammation are redness, swelling, heat, and pain, which are caused by increased blood flow into tissue. Inflammation is produced by eicosanoids and cytokines, which are released by injured or infected cells.

- An enlarged spleen is not always a sign of a problem. When a spleen becomes enlarged, though, it often means it has been doing its job but has become overactive. For example, sometimes the spleen is overactive in removing and destroying blood cells. This is called hypersplenism.he spleen also maintains healthy red and white blood cells and platelets; platelets help your blood clot. The spleen filters blood, removing abnormal blood cells from the bloodstream. A spleen is normally about the size of your fist. A doctor usually can't feel it during an exam.

- Knowledge center. Hyperthyroidism, also known as overactive thyroid, is a medical condition caused by an abnormally high level of thyroid hormone in the bloodstream. The thyroid gland produces an excessive amount of thyroid hormones.The thyroid gland is located in the neck.raves' disease. It is the most common cause. Graves' disease is an autoimmune condition in which the body's immune system mistakenly targets the thyroid gland and causes it to produce too much thyroid hormone.

Medical Dictionary Immune response: Any reaction by the immune system. For example, poison ivy can cause an immune response in the skin characterized by inflammation with tiny blisters, and itching. Also, a flu shot is designed to produce an immune response by stimulating the production of antibodies against the flu virus.

They are divided into four classes (Type I – IV) based on the mechanisms involved and the time course of the hypersensitive reaction. Type I hypersensitivity is an immediate or anaphylactic reaction, often associated with allergy.

- An autoimmune disease is one when the healthy tissues and cells are mistakenly attacked by the body's own immune system. The immune system is designed to attack invaders of the body that do us harm-pathogens.

Disorders of the Immune System An overactive immune system. If you are born with certain genes, your immune system may react to substances in the environment that are normally harmless. These substances are called allergens. Having an allergic reaction is the most common example of an overactive immune system. Dust, mold, pollen, and foods are examples of allergens. Some conditions caused by an overactive immune system are:

Disorders of the Immune System Disorders of the Immune System. Your immune system is your body's defense against infections and other harmful invaders. Without it, illnesses from bacteria or viruses, for example, would be constant. Your immune system is made up of special cells, tissues, and organs that work together to protect you.hen your immune system doesn't work the way it should, it is called an immune system or immunodeficiency disorder. You may: Be born with a weak immune system. This is called primary immune deficiency. Get a disease that weakens your immune system.
