What are allergens, and how do they work?
“A substance that is an allergen for one person may not be for another.”
However, the risk of developing allergies is higher if other family members suffer from allergy or asthma.1
The impact of allergy
Allergic rhinitis has been shown to have a direct and significant impact on an individual’s quality of life:2
World allergy organization estimates 30-40% of the world population is now affected by one or more allergic conditions.2
The rise in the incidence of allergic rhinitis in the GCC countries has been influenced by the rise in pollution and variations in the environmental landscape.3
Allergic rhinitis is common in the middle east.2
Symptoms of allergic rhinitis (hay fever) have been shown to reduce the quality of life and performance at work or school significantly.2
Allergy Types
NOSE, EYES, SINUSES AND THROAT
When you breathe in allergens, an allergic reaction may occur, which may result in the release of a substance called histamine. This then causes the lining of your nose to produce lots of mucus and become swollen and inflamed. The result is a runny, itchy nose, and a violent sneezing. You may also get watery eyes and a sore throat.1
THE LUNGS AND CHEST
Asthma can sometimes be triggered during an allergic reaction. When you breathe in an allergen, the lining of the passages in your lungs may swell and make breathing difficult.1
THE STOMACH AND BOWEL
Most stomach upsets are caused by richness or spiciness in the food itself, rather than an actual allergy. However, certain foods are commonly associated with allergy. These include peanuts, seafood, dairy products and eggs. Cow’s milk allergy is common in infants and can cause stomach upset. Lactose intolerance may also cause stomach upsets, but it must not be confused with allergy.1
THE SKIN
Skin problems such as eczema (dry, red, itchy skin) and urticaria (also known as hives) often occur. Hives are white itchy bumps which look and feel like insect bites. Food may be a factor in some cases of hives and eczema. 1
What is allergic rhinitis
Commonly known as hay fever. Allergic rhinitis is caused by the exposure of the nose or eyes to allergens.4
Some of the most common indoor and outdoor allergens in the GCC countries 5,6,7
Dust mites
Dust
Pet dander
Pollen
Grass
Allergic rhinitis may have significant effects on daily activities and quality of life. 2
It may be seasonal, occurring in spring, summer and early fall, or may come as perennial allergic rhinitis, with symptoms experienced throughout the year. 8
Allergic rhinitis symptoms
Symptoms of allergic rhinitis include2:
Runny nose
Itchy nose
Nasal congestion
Sneezing
Watery eyes
Itchy throat
What is urticaria?
The life-time occurrence of urticaria in the general population ranges from 1% to 5%.9
Urticaria can be triggered by many substances or situations and usually starts as an itchy patch of skin that turns into swollen red wheals10
The itching may be mild to severe, scratching, alcoholic beverages, exercise, emotional stress may worsen the itching.10
There are two types of hives, short lived (acute) and long-term (chronic)10
Common causes of urticaria10
Certain food: such as eggs, nuts and shellfish
Medicines: such as antibiotics, aspirin and ibuprofen
Physical stimuli: such as cold or heat exercise and sun exposure
Pet dander
Pollen
Bacterial infections
Latex
Some plants: such as poison oak
Viral infections
Urticaria symptoms and characteristics10
Symptoms can last anywhere from minutes to months, or even years!
While they may be mistaken for bug bites, hives (also known as urticaria)
are different in several ways:
Hives can appear on any area of the body; they may change shape, move around, disappear and reappear over short periods of time.10
The bumps - red or skin-colored “wheals” with clear edges - usually appear suddenly and go away just as quickly.10
Pressing the center of a red hive makes it turn white - a process called “blanching”. 10
Chronic hives occur almost daily for more than six weeks and are typically itchy. Each hive lasts less than 24 hours.10
