1. Immunodeficiency Disorders
Immunodeficiency happens when a part of the immune system is missing or not working properly. Some people are born with an immunodeficiency (known as primary immunodeficiency), although symptoms of the disorder might not appear until later in life. Immunodeficiency also can be acquired through infection or produced by drugs (these are sometimes called secondary immunodeficiency).
Immunodeficiency can affect B lymphocytes, T lymphocytes, or phagocytes.
Primary immunodeficiencies can affect kids and teens.
Acquired (or secondary) immunodeficiencies usually develop after someone has a disease, although they can also be the result of malnutrition, burns, or other medical problems. Certain medicines also can cause problems with the functioning of the immune system.
2. Autoimmune Disorders
In autoimmune disorders, the immune system mistakenly attacks the body’s healthy organs and tissues as though they were foreign invaders. Examples are Rheumatoid arthritis, Ankylosing spondylitis.
3. Allergic Disorders
4. Cancers of the Immune System
Although immune system disorders usually can’t be prevented, you can keep your immune system in a healthy state, and fight illnesses, by the help of some natural health food supplements.
The immune response can be manipulated to either suppress unwanted responses resulting from autoimmunity, allergy, and transplant rejection or to stimulate protective responses against pathogens that largely elude the immune system or cancer.
Immunostimulation – Cancer immunotherapy covers the medical ways to stimulate the immune system to attack cancer tumours.
Any product, natural or synthetic that brings the immune system to its natural state is referred to as an ideal immunomodulator.
