Your immune system to attack
Many people suffer from some form of allergy or sensitivity. Why the body does allergic to certain substances? Is there a cure?
Allergy is an abnormal reaction of the immune system to contact with a foreign substance, an allergen. Contact can take place through the skin, the mucous membrane of any part of the respiratory tract, or the mucosa of the digestive tract.
Causes:
The allergic reaction after a first exposure may occur and takes different forms such as eczema hay fever, allergic asthma and food allergy. People with allergic reactions produce much more amount of the antibody immunoglobulin (IGE) than the normal. They also produce much more amounts of a specific granular cell than normal. IGE binds to mast cells.As an allergen, such as a grain of pollen, connects himself with the IgE, the membrane of the mast cell becomes distorted. It rips and thereby get some very irritating substances histamine are released. These substances cause the allergic symptoms.
Infections are required:
In the defense against infections T-helper cells - a type of white blood cell plays key role. Th1 cells come into action when an infection and deliver substances attack and destroy unwanted invaders. Th2 cells produce substances that are involved in the allergic reaction. Normally, these two cells are balanced, but if more Th2 cells, there may be an allergic reaction.Due to infections after teaches a baby is using Th1 cells against bacteria and viruses to defend, which possible to decrease the chance of an allergy. In the absence of infection, Th2 cells remain boss. You can then get allergies.
More and more allergies:
Improved hygiene and vaccinations make children less infections. Especially in Western countries, the number of allergies is striking. For example, only 3 percent of the Albanian children suffered from asthma, compared with 22 to 40 percent of British children. In a cleaner environment we come with less bacteria and viruses in touch, making our bodies less defensive builds. Research shows that 40 percent of animals live longer after exposure to small amounts of chemicals and radiation.Dirt is not all bad. Children develop regular contact with farm animals less likely an allergy. Italian scientists discovered that soldiers with antibodies against the hepatitis A virus had fewer allergies than peers without these antibodies. Hepatitis A is transmitted through feces, contaminated food and water.
According to a British study, young children take daily bathing and at least five times a day to wash their hands more likely to develop allergies than children who do not often do. Research at the National Jewish and Research Center in Denver involving 1680 newborns showed that babies are less prone to allergies as their ancestral home more substance.
A remedy for allergy:
The best recipe against allergy is to avoid contact with the substance to which one is allergic. But that is not always easy and sometimes impossible. First, it is important to examine exactly what substance it is allergic. Your doctor may furnish prescription drugs, such as antihistamines. Itching is often prescribed as a cream or ointment. An increasingly used method is desensitization.The aim is that through careful contact with the allergen is a certain habituation. It is a good method, but in a long way that is not guaranteed. If you have a severe reaction resembling allergy or hypersensitivity, contact your doctor.
