This treatment is sometimes used, mainly in allergy cases that are most severe such as reactions causing anaphylaxis and where symptoms are not helped much by other treatments. People with life-threatening reactions to wasp or bee stings, those with severe hay fever and some people with some animal allergies are suitable for immunotherapy. Immunotherapy is usually unhelpful if you have multiple allergies, food allergies or allergic rashes. It is done using a series of injections to desensitise the immune system.
The allergen you are allergic to is administered in tiny quantities, via an injection. The amount used is too small to provoke the allergic reaction, but enough to teach the immune system not to produce the huge quantities of IgE antibody.
The hygiene hypothesis may play a role here, too, Dr. Processed foods disrupt the balance of good and bad bacteria in our gut, she says. Research suggests that when the gut microbiome is thrown off, it can interfere with our immune responses.
Some studies have even shown that rebalancing the bacterial environment in the gut could prevent serious allergic reactions. What to do: Go see an allergist and find out for sure. What not to do: Just say, "Ugh, I have allergies, woe is me," like I do. There are different treatments, and one over-the-counter medication might not work as well as the next.
Wash the few favorites your child can't live without in hot water weekly or stick them in the freezer for an overnight killing frost. Dust and vacuum weekly or every other week, but make sure your child isn't in the room when you do it. Dusting and vacuuming stir up residual dust-mite particles in the room. Wet mopping can help prevent this. Consider investing in a vacuum cleaner with a HEPA high-efficiency-particulate-arresting filter, which traps even microscopic particles that pass right through ordinary vacuum cleaners.
If your child has a severe dust mite allergy, consider replacing carpeting with a smooth floor like hardwood or vinyl. Clean or replace filters on your furnace and air conditioners monthly during seasons they're in use. Have heating ducts cleaned each fall.
