What does the autoimmune system do

What is autoimmune system? It recognises the cells that make up your body, and will try to get rid of anything unfamiliar. It destroys germs (bacteria and viruses) and parasites. But this defence system can also cause problems.

For example, if you inhale a cold virus through your nose, your immune system targets that virus and primes you to recover. It takes time to get over an infection, and sometimes you need medicine to help,.

An autoimmune disease is a condition in which your immune system mistakenly attacks your body. The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them.

Aside from the nervous system , it is the most complex system in the human body. When the immune system does not function properly it leaves the body open for attacks from.

Bacterial Infections, Viral infections, all infections and toxins. If you did not have an immune system your body would not be able to function. Individuals with autoimmune diseases can die from the common col because their immune systems.

Inside your body there is an amazing protectio­n mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. No matter what type of autoimmune disease you have, the true problem (and solution) lies with your immune system. Your immune system has a very sophisticated system for keeping you safe that leads it to identify all of the foreign substances that enter your body or impact you in any way. In chronic inflammatory diseases, neutrophils and other leukocytes are constitutively recruited by cytokines and chemokines , leading to tissue damage.

On a basic level, autoimmune disease occurs because the body’s natural defenses — the immune system — attack the body’s own healthy tissue. Researchers have several ideas about why this happens. When the body senses danger from a virus or infection, the immune system kicks into gear and attacks it.

When you have an autoimmune disorder, your immune system does not distinguish between healthy tissue and potentially harmful antigens. As a result, the body sets off a reaction that destroys normal tissues. Why do autoimmune diseases develop?

But, for most autoimmune illness – including those mentioned above – the true cause is unknown. Immune system definition is - the bodily system that protects the body from foreign substances, cells, and tissues by producing the immune response and that includes especially the thymus, spleen, lymph nodes, special deposits of lymphoid tissue (as in the gastrointestinal tract and bone marrow), macrophages, lymphocytes including the B cells and T cells, and antibodies. In some types of hypothyroidism, for example, the body can attack cells that produce thyroid hormone, interfering with the production and function of the hormone.

If your immune system deems anything dangerous, it will produce antibodies to ward off the harmful intruders.

Although there are many different types of autoimmune diseases and they can affect many different organs, at their core they are all similar in that they are an immune response caused by systemic inflammation that leads your body to attack itself. There are at least types of autoimmune diseases. Nearly any body part can be involved. Common symptoms include low grade fever and feeling tired.

Often symptoms come and go. The cause is generally unknown. Some autoimmune diseases such as lupus run in families, and certain cases may be triggered by infections or other environmental factors.

Autoimmune diseases refer to problems with the immune system , which usually fights off viruses, bacteria and infection. The problem causes your immune cells to attack your body by mistake. These diseases can affect almost any part of the body.

In most cases, your doctor will prescribe medications to reduce redness, pain, and swelling.
