Simple Explanation of Food Allergies

You Asked Food Allergies Explained

by: News Canada

(NC)-Life-threatening allergies (anaphylaxis) may affect more than 600,000 Canadians, a number that has increased dramatically in just one decade. Foods account for most cases of anaphylaxis in children, whereas drugs are more often the cause with increasing age. For potentially life-threatening reactions, injectable adrenaline, also known as epinephrine, should be administered rapidly, no matter how mild the early symptoms appear. Here are some of the most frequently asked questions on anaphylaxis:

Perennial Allergic Rhinitis

Viktor Radcliff

There are two types of allergic rhinitis: seasonal allergic rhinitis (hay fever)- when symptoms are experienced only during spring and/or summer, and perennial allergic rhinitis (PAR) - when symptoms are experienced all year round.

The allergens that most commonly cause perennial allergic rhinitis are house dust, dust mites, cockroaches, cat or dog dander, and fungi or molds.

Industrial dust,fumes and chemicals can cause an occupation-related allergic rhinitis.

There is often a family predisposition to developing perennial allergic rhinitis and other allergies.

The symptoms of perennial rhinitis are described as like those of a permanent cold: blocked stuffy nose,constant sore throats and postnasal drip,headaches,loss of taste and smell.People with allergic rhinitis, particularly those with perennial allergic rhinitis, may experience sleep disorders and daytime fatigue.Some people with perennial allergic rhinitis show poorer psychological functioning than non-allergic people.

Symptoms of perennial allergic rhinitis always flare up indoors.

The only way to prevent perennial allergic rhinitis is to avoid the allergen that causes it.For perennial allergic rhinitis caused by dust and dust mite, this means using dust mite covers for pillows and mattresses,cleaning floors and walls with a damp mop, and using an air purifier.For perennial allergic rhinitis caused by animal dander,keeping pets out of the bedroom, and off furniture, rugs and other dander-catching surfaces and having pets bathed and groomed frequently is the best solution.

Although perennial allergic rhinitis resembles the seasonal rhinitis in some ways, there are important differences in treatment options : perennial symptoms stem from allergens being inhaled deep into the lungs, so many medications that are effective in treating hay fever symptoms will be less effective.

Intranasal corticosteroid sprays have become the main recommended treatment in perennial allergic rhinitis,especially in patients with moderate or severe PAR.Decongestant sprays and tablets will help relieve a stuffy, blocked nose with catarrh.However,they should be used for short periods only.Anti-histamine medication may help, but it is far less effective than for hay fever.

Allergy testing is very important so you can identify the exact indoor allergen that causes the allergy.

Q: What are the triggers of anaphylaxis?

A: The most common causes in the North American population include foods, drugs, insect stings and natural latex rubber. Peanut is the food allergen most commonly associated with life-threatening reactions, but any food can trigger anaphylaxis in a sensitive individual.

Q: What is the difference between anaphylaxis and other allergic reactions?

A: While many of the initial symptoms of anaphylaxis may be similar to milder allergic reactions (itchy eyes, hives) anaphylaxis is characterized by involvement of more than one body system and, usually a rapid progression of symptoms that can lead to death. If there has been a past history of anaphylaxis, it is safest to assume that the reaction will again lead to anaphylaxis and give epinephrine at the earliest sign.

Q: What is the best plan-of-action in the event of anaphylaxis?

A: Learn as much as possible about recognizing the symptoms, how to be ready, and how to administer the medication with an auto-injector. Even when symptoms are mild, if you suspect your child was exposed to a trigger, it is important to immediately inject epinephrine, and then head straight to a medical facility. A dose of epinephrine lasts for only 10 to 20 minutes, so patients should carry a separate dose for each 15 minutes of travel time to a medical facility, to be administered only if symptoms persist. Other precautions include: checking the expiry date on the medication, and for a change in its colour; making sure that your child care providers, teachers and other adults know about the child's allergy; wearing a Medic-Alert bracelet or necklace indicating the allergy; checking food labels carefully, and asking about menu ingredients at restaurants.

As part of a nationwide initiative to answer pressing questions on anaphylaxis, a special pharmacist-directed, HealthWatch for Children Day is planned at 800 Shoppers Drug Mart/Pharmaprix locations, on Thursday, Sept. 19. Just ask your HealthWatch pharmacist for an appointment. Or, if you miss this information day but have questions on allergies, be sure to direct them to your doctor, or to any HealthWatch pharmacist at Shoppers Drug Mart/Pharmaprix.
