Allergies An allergy is when you’re very sensitive to a substance. If you’re allergic to something, it acts as an antigen. When your immune system kicks in, you will get an allergic reaction. Anything that causes an allergic reaction is called an allergen. An allergen could be food, cats, pollen or dust. Histamines Histamine is chemical your body uses when you have an injury or when you need to fight off things such as allergens. You get symptoms such as watery eyes or a runny nose because it’s a side effect of histamine. To reduce the symptoms of the histamine you can take an antihistamine but is does not cure the allergy itself. Taking Care of the Immune System To keep your immune system healthy you can: Have a well-balanced diet Personal hygiene (shower/bathe, brush teeth, wash hands often, etc.) Have a clean home Avoid tobacco and other non-perscription drugs Get lots of rest and exercise Have up to date vaccinations Don’t share body fluids with others (saliva for example) Try to keep a low stress level AIDS(Acquired Immunodeficiency Syndrome) Infection of immune system that leads to various health complications, and often death. So far, AIDS had resulted in more than 11 million deaths, and currently is affecting 40 million people. The Cause of AIDS The cause of the AIDS is the human immunodeficiency virus (HIV). HIV is a powerful pathogen that attacks the immune system. HIV can destroy the immune system by infecting the helper T cells, which means when other pathogens or antigens enter the body, the immune system is unable to activate killer T cells or B cells. People infected with HIV can die from other less serious infections like pneumonia. There is no known cure for AIDS because HIV keeps changing it’s structure slightly which makes it difficult to identify the antigens on the virus. Auto-Immune Disease Auto-Immune disease happens when the body mistakes it’s own cells for pathogens and attacks them. Celiac Disease Celiac disease is a type of auto-immune disease. Gluten becomes an enemy to people that have celiac disease. When people with celiac disease eat gluten, a protein found in barley, wheat and rye, their immune system will attack their small intestines. The disease makes it very difficult to absorb nutrients. Untreated celiac disease can lead to infertility, osteoporosis, neurological conditions, and, very rarely, cancer. Celiac disease is very tricky to diagnose because it doesn’t have many obvious symptoms. Rheumatoid Arthritis Rheumatoid Arthritis damages the cartilage and bones. It affects the hands, wrists, feet, knees, ankles, shoulders, neck, jaw, and elbows. It causes pain, swelling, inflammation in joints, and restricts motion. It happens when the body rejects it’s tissue cells and there is inflammation of synovial that lines joints. It makes it so that there is more releasing of the synovial fluid which makes it thicker and causes swelling. Multiple Sclerosis Multiple Sclerosis is a disease where the immune system attacks nerve tissues and the central nervous system. It usually causes damage to the central nervous system occasionally, so you can still live a pretty normal life. If the disease is very severe it could result in blindness, paralysis, and premature death. It is the most common disabling disease of the nervous system for young adults. Test Questions What is an allergy? What is one of the effects of rheumatoid arthritis? What is the cause of AIDS? What is the name of the protein found in wheat, barley, and rye? What are three ways to care for your immune system?
