Understanding Food Allergy

During an allergic reaction, the immune system responds to a normally harmless substance as if it were a threat. In some people, common foods such as milk, eggs, and peanuts can trigger such a reaction. So how does this work If you have a food allergy, your immune system makes a type of antibody called immunoglobulin E, or IgE. This class of antibody binds to immune cells called mast cells and basophils that circulate throughout your body. When you are exposed to the food allergen, it attaches to the IgE antibodies.

This binding signals the immune cells to release histamine and other chemicals that cause allergy symptoms, such as swelling of the lips, hives, and shortness of breath. Because mast cells and basophils rapidly release these chemicals, an allergic reaction typically occurs within 30 minutes after exposure. The most severe kind of reaction is called anaphylaxis, which can cause a sudden drop in blood pressure, trouble breathing, dizziness, and possibly death. People with food allergy and poorly controlled asthma are more susceptible to severe reactions. An anaphylactic episode must be treated with a hormone called.

Epinephrine, which maintains blood pressure and opens up the airways. To deal with accidental exposure, people diagnosed with food allergy are prescribed a medical device called an autoinjector that delivers a single dose of epinephrine into the thigh muscle. Antihistamines alone are not an effective treatment for anaphylaxis. There is no cure for food allergy. The best way to manage the condition is to avoid the allergenic food, read food labels carefully, wash hands and household surfaces, and always carry an epinephrine autoinjector. If you are accidentally exposed to a food allergen,.

Symptoms of an Allergy to Cats From the makers of ZYRTEC

Move over, Rover. Cats are the most popular pet in America. Not only are felines found in a whopping onethird of households, but cats are also the leading cause of pet allergies in the U.S. Contrary to popular belief, fur does not actually cause cat allergies. It is cat dander and saliva that trigger symptoms. Within seconds to minutes of exposure sneezing may start, followed by a sudden runny nose, even itchy, watery eyes. The longer you are exposed, the worse your symptoms usually get, including ongoing nasal stuffiness, sinus pressure over the eyes or in the cheeks and an itchy throat. So, avoiding cats altogether.

Is the best way to minimize symptoms but even then there are no guarantees. There are eightyfive million cats in U.S. homes and nearly as many strays. So just being out in public may expose you to enough cat allergens to develop an allergy and trigger symptoms. But it's not all bad news if you enjoy spending time around cats, talk with your doctor. Treatment can help relieve allergy symptoms and might help you enjoy Fluffy's company for years to come. For Allergy relief plus a powerful decongestant, ask for ZyrtecD.

Man's best friend may be no friend to you if you are among the roughly five million Americans with an allergy to dogs.

What is an Allergic Reaction From the makers of ZYRTEC

It happens to one in seven Americans, and it often strikes with little warning. It is an allergic reaction triggered by airborne allergens. An allergic reaction is an adverse response by the immune system to normally harmless substances, like pollen. Here's what happens The immune system misidentifies pollen as a harmful substance which causes the immune system to overreact and create antibodies that will stick to pollen the next time it enters the body and trigger the release of histamine and other substances. It's this process that leads to allergy symptoms, like sneezing, runny nose, and itchy, watery.

Eyes. The allergen antibodies are designed to flag specific types of allergens. This is why someone can be allergic to pollen from Bermuda grass but not pollen from another source, like an oak tree. Once your immune system creates an antibody against an allergen, you'll experience an allergic reaction every time you encounter it. To help prevent flareups, try to avoid allergens you're sensitive to and consider using medications, such as antihistamines, to relieve symptoms. The more you know about your allergies, the more you can do to help manage symptoms, so you can get on with the day. Try Zyrtec for powerful.
