All About Allergies: A Unit Study
- Monday, March 30, 2009
Finding out you are allergic to something isn’t any fun. Many things you might have enjoyed eating may now be off-limits. Some people are allergic to corn, wheat, and other grains. Others might be allergic to milk and dairy products. There are those allergic to peanuts and nuts, while some are even allergic to fish and meat products.
Allergies and sensitivities to things around us come in many forms. Food allergies, like the ones listed above, are just a few of many. Many people struggle with environmental allergies like pet dander, molds, grass, pollen, and trees. The number of people who are allergic to chemicals is growing steadily every year. These people need to avoid cleaning products like laundry detergents and soaps, as well as dyes, pesticides, and certain medicines like penicillin.
How an allergy affects us varies greatly from one person to the next. Sometimes it’s not the obvious signs of sneezing, watery eyes, or a case of hives that tell us we are allergic. Allergies can change people’s emotions or make them hyperactive. Allergies might make muscles and joints ache, or become a cold that never seems to go away.
It’s often thought that a person’s allergies are inherited. Statistics show that if one of your parents has allergies, you are 50% more likely to develop allergies as well. If both of your parents have allergies, your chances jump to 75 %. But inheriting allergies is not the only way a person can develop them. Food allergies can be caused by a weak immune system or by eating the same foods over and over. Environmental allergies can occur by overexposure.
So how do you find out if you have allergies? Most people will go to their doctor to have tests taken. There are skin tests, blood tests, and alternative methods like muscle testing. You can become a detective yourself and possibly discover allergies by keeping a diary of what you eat or what you are exposed to and the symptoms that result.
