Is it allergies or something else?
Spring has arrived, and with it comes a familiar set of symptoms for millions of people across the UK: a runny nose, itchy eyes, persistent sneezing, and that vague, foggy feeling that makes it hard to get through the day.
Most of us put it down to hay fever and reach for an antihistamine. But how confident are you that what you are experiencing is actually an allergy – and not something else entirely?
This week is Allergy Awareness Week, and this year’s campaign, ‘I Wish I Knew’, focuses on a message that resonates deeply in general practice: diagnosis matters. Many people spend years managing symptoms they have never properly investigated, missing out on treatments that could genuinely change their quality of life.
Why allergy is so often missed or misunderstood
Allergy is far more prevalent than many people realise. It is estimated that by 2026, one in two people across Europe will be living with some form of allergic condition. Yet despite this, allergies frequently go undiagnosed – or are misidentified as something else altogether.
Part of the reason is that allergic symptoms overlap with a wide range of other conditions. Sneezing and a blocked nose in spring could be hay fever, but they could equally point to a perennial non-allergic rhinitis, which is not driven by pollen at all. Itchy, watery eyes might suggest an allergic response, but could also be due to blepharitis or dry eye disease. Skin reactions that look like eczema may have entirely different triggers. And recurrent respiratory symptoms can sometimes reflect undiagnosed asthma – a condition strongly associated with allergy – rather than a series of coincidental colds.
Allergies can develop at any stage of life
One of the most important things to understand about allergic conditions is that they are not fixed in childhood. Allergies can develop at any point; during adolescence, pregnancy, or well into adulthood. Adults who have managed perfectly well through spring for decades can suddenly find that pollen season brings misery. New food intolerances can emerge after illness or hormonal change. Drug reactions can appear in people with no previous history of allergy.
This is why dismissing symptoms with ‘it’s never bothered me before’ is not always a reliable guide. The immune system changes throughout life, and an allergy that was not present at thirty may be very present at fifty.
When symptoms could be telling you more
There are situations in which what appears to be a seasonal allergy warrants closer attention. If your symptoms are year-round rather than seasonal, or seem to flare indoors as much as outside, dust mite allergy, mould sensitivity, or pet dander may be playing a role.
If you are using antihistamines regularly but still feel unwell, or if your symptoms are affecting your sleep, concentration, or ability to exercise, this is a signal that better investigation and management are needed.
Crucially, allergic conditions rarely exist in isolation. Research shows that people with hay fever are four times more likely to develop other allergy-related conditions, such as asthma and eczema, often termed the ‘atopic triad’.
Uncontrolled allergic disease can also significantly worsen existing respiratory conditions. A thorough diagnosis is not just about naming the allergy – it is about understanding the full picture of your health.
What a proper allergy assessment involves
A comprehensive allergy assessment starts with a detailed clinical history: understanding your symptoms, when they occur, what makes them better or worse, and whether there are any patterns linked to environment, food, exercise, or medication. This is often the most informative part of the process.
From there, we can arrange specific IgE blood tests to identify sensitisation to a wide range of allergens, including tree and grass pollens, house dust mite, animal dander, moulds, and common food triggers. Where appropriate, we can refer for formal allergy specialist testing, including skin prick tests or supervised oral food challenges. The goal is not simply to confirm a suspicion, but to arrive at a diagnosis that is accurate enough to guide effective management.
Getting the right diagnosis changes everything
The message at the heart of this year’s Allergy Awareness Week is one we fully support: the right knowledge at the right time can change the course of an allergy journey. With an accurate diagnosis, antihistamines can be used more strategically, allergen avoidance becomes practical rather than guesswork, and for many patients, immunotherapy – which can meaningfully desensitise the immune system to specific triggers – becomes an option worth exploring.
If you have been dealing with Spring symptoms year after year or are unsure whether what you are experiencing is an allergy, we encourage you to book a consultation. A thorough GP assessment is the first and most important step, and it may well be the one you wish you had taken sooner.
