الحساسية Allergy

What is an allergy?

An allergy is a reaction of the immune system to something that does not bother most people. People with allergies are often sensitive to more than one thing. Allergies occur when the immune system reacts to a foreign substance or food that does not usually cause a reaction in most people. Some of the substances that commonly provoke reactions are: pollen, dust mites, mould spores, some foods, insect bites, medicines…

Normally, the immune system fights germs. It is the body’s defence mechanism. However, in most allergic reactions it responds to a false alarm. It is possible that genetics and environment play a role in the development of allergies.

Causes of allergy

Allergies begin when the immune system mistakes a harmless substance for a dangerous invader. The immune system produces antibodies that stay awake to this allergen. When re-exposed to an allergen, these antibodies can release a number of immune system chemicals, such as histamine, that cause allergy symptoms. Some of the most common causes of allergies are:

  • Airborne allergens, such as pollen, pet dander, dust mites and moulds.
  • Certain foods, especially peanuts, tree nuts, wheat, soy, fish, shellfish, eggs and milk.
  • Insect stings, such as bee or wasp stings.
  • Medicines, especially penicillin or penicillin-based antibiotics.
  • Latex or other materials that are touched, which can cause allergic skin reactions.
  • If you have a family history of asthma or allergies, such as allergic rhinitis (hay fever), hives or eczema.

Types of allergies

There are many types of allergies that a person can have during their lifetime, and these are the most important ones, depending on the nature of the allergens:

  • Medication. A drug allergy is a rare type of allergy, as most drug reactions are not allergic and can be side effects of the drug. It can cause: hives, itchy skin, rash, facial swelling, wheezing, anaphylaxis…
  • Food. There are many types of allergies associated with different foods, but here we must differentiate some types of eating disorders, such as: lactose intolerance and sensitivity to certain types of food. It can cause: tingling sensation in the mouth, swelling of the lips, tongue, face or throat, urticaria, anaphylaxis…
  • Pets. Allergies to pets, especially those with fur or dander, are a common type of allergy. Especially to animals, such as cats and dogs.
  • Insects. Certain types of insects are more likely to cause an allergic reaction to stingers than others, including bees, wasps and fire ants. They can cause: large-area swelling (oedema) at the site of the sting, itching or hives all over the body, coughing or tightness in the chest, wheezing or difficulty breathing…

How can allergies be prevented?

Prevention of allergic reactions depends on the type of allergy you have. Some general measures are as follows:

  • Avoid known triggers. Even if you are treating your allergy symptoms, try to avoid triggers. For example, if you are allergic to pollen, during peak pollen times, stay indoors with doors and windows closed. If you are allergic to dust mites, dust, vacuum and wash sheets often.
  • Keep a diary. When trying to identify what causes or worsens your allergy symptoms, record your activities, what you eat, when symptoms occur and what seems to help. This can help you and your doctor identify triggers.
  • Wear a medical alert bracelet. If you have had a severe allergic reaction, a medical alert bracelet (or necklace) can be used to warn others that you have a severe allergy, in case you have a reaction that prevents you from communicating.
