You wake up most mornings with a blocked nose, your eyes itch by mid morning, and by the time the rainy season arrives you have given up trying to work out why. Most people simply live with it, blaming dust, the weather or bad luck.

An allergy is not bad luck. It is a specific, identifiable reaction, and in many cases the trigger can be found and managed once you stop guessing.

The useful idea in this article. An allergy is your immune system treating something harmless as a threat. The symptoms are real, the trigger is usually findable, and the difference between a nuisance and an emergency comes down to a few warning signs worth knowing.

What an allergy actually is

Your immune system is built to attack genuine threats such as bacteria and viruses. An allergy is what happens when it mistakes a harmless substance, such as pollen or a certain food, for one of those threats and mounts a full defence against it.

That defence releases a chemical called histamine, which is what produces the sneezing, itching, swelling and runny nose. The substance that sets it all off is called an allergen.

Our warm, humid climate suits several of the most common allergens all year round. Dust mites thrive in bedding and soft furnishings. Mould grows quickly in damp corners, especially through the wet season.

Grass and tree pollen affect many people, and pet fur is a frequent culprit at home. Food allergies, particularly to shellfish, peanuts, tree nuts, eggs and cow milk, are common too, and so are reactions to insect stings and to certain medicines.

The symptoms to recognise

Allergic reactions show up in a few predictable places. In the nose and eyes you get sneezing, congestion, a clear runny nose and itchy, watering eyes, often called allergic rhinitis when it keeps coming back.

On the skin they appear as raised, itchy welts known as hives, or as the dry, inflamed, itchy patches of eczema. In the chest, allergens can trigger wheezing and breathlessness, which overlaps closely with asthma.

Go to Accident and Emergency straight away if a reaction involves swelling of the lips, tongue or throat, difficulty breathing or swallowing, a tight chest, dizziness or fainting, or a widespread rash that comes on fast. This is anaphylaxis, a severe whole body allergic reaction that can be life threatening within minutes. If someone has an adrenaline auto injector, use it and still come in at once.

When to get it looked at

You do not have to live with year round symptoms. See a doctor if your symptoms interfere with sleep, work or school, if over the counter remedies are not controlling them, or if you have ever had a sudden strong reaction to a food, a sting or a medicine.

Finding the trigger matters most when reactions have been severe, because avoiding that one allergen becomes a safety issue rather than a comfort one.

How allergy testing works

Testing turns guesswork into a plan. A consultation comes first, where the doctor maps out your symptoms, their timing and your home and work surroundings, which on its own often points to the likely culprit.

Laboratory allergy blood testing can then measure your immune response to specific allergens, and this is available in our on site laboratory. If a skin prick test is the better next step for your situation, we will arrange a referral to the appropriate specialist.

Managing allergies day to day

The most powerful treatment is avoidance, once you know what to avoid. Practical steps help a great deal: washing bedding in hot water, reducing damp and mould at home, keeping pets out of the bedroom and closing windows on high pollen days.

For symptom relief, doctors commonly use antihistamines, a class of medicine that blocks the histamine reaction, along with steroid nasal sprays for a persistently blocked nose. Anyone at risk of a severe reaction should carry an adrenaline auto injector and know exactly how to use it. Your doctor will advise what is right for you.

The bottom line

Allergies are common and they are manageable, but only once you know what you are reacting to. If you have spent years assuming this is just how your body is, a single consultation is often enough to start changing that.

Book an appointment, describe your symptoms honestly, and let testing do the detective work. And if a reaction ever affects your breathing or your throat, do not wait, come straight in.
