5 Things You Need to Know About Allergies

1. The Immune System Gone Wild

It is estimated about 20 to 30 percent of Americans suffer from some type of allergy. An allergic reaction occurs when you eat or come in contact with something that causes your immune system to overreact. Although the substance is harmless the immune system goes into attack mode and releases histamines that cause allergy symptoms. Common allergens which trigger symptoms include foods such as shell fish and peanuts, pollen, pet dander and bee stings.

2. Prevent Allergies by Reducing Allergens

Identify your triggers and take steps to reduce them. For example if you are allergic to pollen use an air conditioner and keep doors closed. Wash bedding often to reduce dust mites. If mold is a trigger use a dehumidifier in your home to keep moisture out. Limit the number of plants you have which can grow mold and trigger symptoms. If pet dander is a problem don't allow pets to sleep on your bed which causes you to breath in the dander all night long. Vacuum up pet hair often and consider getting a HEPA air filter to help clean the air in your home.

3. Annoying Allergy Symptoms

You may know the feeling, your eyes start itching and become watery, the sneezing starts and your nose is runny. They are all common allergy symptoms. The type of reaction you have may depend on what you are allergic to. For example if you have a food allergy symptoms may include nausea and vomiting. Other common symptoms include rashes and hives.

4. Alleviate Allergies With Treatment

Allergies are usually treated with medications. Antihistamines can be bought over the counter and help to reduce sneezing, itchy and watery eyes. Keep in mind antihistamines often cause drowsiness. If your main allergy symptoms include a stuffy nose decongestants may help. They will reduce the swelling in the nose and help drain mucus that is caused by an allergen. If your allergies are severe or medication does not help your doctor may prescribe allergy shots. Shots help by increasing tolerance to the allergen.

5. Allergies Can Lead to Anaphylaxis

Anaphylaxsis is a severe allergic reaction. Although it is rare it can be life threatening. The throat can swell and block the airway. Initial symptoms of anaphylaxis include hives, swelling of the face or throat which may cause wheezing or strider. The skin may become flushed and the heart rate increases. Medical attention is needed at the first signs of anaphylaxis. Individuals who have had severe allergic reactions in the past should consider carrying an EpiPen which contains a pre measured dose of epinephrine.
