An allergy is the body’s way of reacting to certain substances or foods. It affects one in every four people in the EU and can hit people at any time of their lives.
Allergy symptoms range from mild to severe reactions depending on the person experiencing it. Some substances are generally known to cause allergies in large groups of people, including pollen, grass, dust, and specific foods.
Children often suffer from allergies more than adults do. But once you get an allergy in childhood, that’s likely to stick with you for the rest of your life. Some allergies may disappear as a child gets older. Still, some adults with previous allergic histories may develop allergies to new substances later in life.
Avoidance of allergic reactions is typically grounded on proper communication between the allergy sufferer and the people around him. You must inform people of your allergy to avoid exposure to the allergen as much as possible.
Allergies often have mild symptoms and are easily treatable. However, there are many exemptions to this, as allergic reactions can also become full-blown severe and could cause life-threatening situations if not promptly attended to.
When a person comes into contact with an allergen, the immune system activates and produces antibodies to target the substance it deems as harmful. This reaction can cause varying degrees of inflammation on the skin, airways, sinuses, and digestive system. Such inflammation presents as irritation and minor rashes to some people. However, others may also get full-fledged anaphylaxis which is a medical emergency.
The following substances are the most common and prevalent allergens in the EU:
Allergies are heightened immune responses to typically harmless substances. Intolerance, on the other hand, is a condition that produces symptoms without involving the immune system. They may share similar symptoms, but in essence, they are not the same.
Allergies and intolerances are both different from sensitivity. Sensitivities are conditions where a provoking substance elicits exaggerated, albeit not extreme, effects on the body. For example, caffeine sensitivity could lead to heart palpitations or trembling when you drink coffee or eat chocolates.
There are three things a doctor may do to diagnose an allergy:
For suspected food allergies, the doctor may also check the patient’s weekly food log. He may also identify a suspected food allergen together with the patient, then instruct the allergy sufferer to stop eating it for some time, then report back to the clinic to check if the allergy symptoms subsided.
Other diagnostic routes may include:
Research still cannot pinpoint why allergies happen to people. However, medical evidence points out to people having family histories of asthma, eczema, and allergies as those who are more prone to becoming allergic to something.
The number of reported allergy cases keeps on increasing every year. Why this happens is also not that clear, but many believe in the so-called “Hygiene Hypothesis” theory. Its premise is that people nowadays are more predisposed to developing inappropriate immune responses to harmless substances simply because we live in a cleaner environment and have the tools to become extremely clean at our disposal.
We’ve been protecting ourselves from infections by being extremely clean. This results in reduced exposure to both harmful and harmless substances. This can send the immune system into overdrive. Now, when the body encounters a harmless substance, the immune system immediately reacts inappropriately, paving the way for an allergy.
Here is a list of the most common allergic reactions prevalent in the EU today.
Allergy symptoms greatly vary depending on the general triggering factor that caused it:
Pollens:
Food:
Insect stings or bites:
Medicine:
The initial treatment for mild allergies is simply to avoid the triggering substance. It involves precisely identifying your triggers and adjusting your environment and diet to allow for as much avoidance of the trigger as possible. Good communication between you and the people around you will make allergy avoidance easier.
The best allergy prevention measure is to avoid the triggering substance as much as you possibly can. People who are at risk for severe allergic reactions such as anaphylaxis must carry at least two adrenaline auto-injectors with them at all times. Let your family members and friends know about your allergic reactions so that they can administer the shots to you in an emergency situation.
