Could you be developing a new allergy? Here's what to look out for
Allergies can develop at any stage of life, even if you have never had symptoms before. Whether it’s triggered by something you eat, breathe in, or come into contact with, an allergy happens when your immune system reacts to a substance it sees as a threat, even though it’s usually harmless to others.
Recognising the signs early can help you take steps to manage symptoms and avoid future flare-ups. Here's what to watch for:
Common signs of a new allergy
1. Respiratory Issues
Sneezing, coughing, wheezing, or shortness of breath may point to allergies like hay fever, dust mites, or reactions to pets.
2. Skin Reactions
Itchy skin, rashes, redness, hives, or swelling can indicate an allergy to food, skincare products, insect bites, or environmental factors such as pollen or mould.
3. Digestive Symptoms
Nausea, bloating, abdominal cramps, or diarrhoea may be linked to food allergies or intolerances. These symptoms can be mistaken for other digestive issues, so it's worth keeping track of what you have eaten.
4. Eye and Nose Irritation
Watery, itchy eyes and a runny or blocked nose are classic allergy symptoms, often related to airborne allergens like pollen or pet dander.
5. More severe reactions
In rare cases, allergies can trigger a serious reaction known as anaphylaxis. This is a medical emergency and can include symptoms like difficulty breathing, rapid heartbeat, dizziness, or swelling of the face, lips, or throat. If you or someone around you experiences these, seek immediate medical help.
What to do if you suspect an allergy
If you think you might be developing a new allergy, don’t ignore the signs. Here are some practical steps to help you get to the root of the problem:
- Keep a symptom diary
Write down when your symptoms occur, what you have eaten, where you have been, or any new products you have used. This can help identify patterns and assist your doctor in pinpointing the cause. - Avoid suspected triggers
If you have a hunch about what is causing your symptoms -whether it’s a certain food, a pet, or a cleaning product - try avoiding it for a while to see if your symptoms improve. - Use over-the-counter remedies
Antihistamines, nasal sprays, or eye drops can offer relief for mild symptoms. Ask a pharmacist for advice if you're not sure which product is right for you. - Consult your GP
If your symptoms persist, worsen, or are interfering with your daily life, speak to your doctor. They may recommend allergy testing or refer you to a specialist to help identify your triggers and discuss treatment options.
Final thoughts
Allergies can be frustrating, especially when they seem to appear out of nowhere. However, with the right approach, they can usually be managed effectively. By learning to spot the signs and knowing when to seek help, you can take control of your symptoms and feel more confident in your everyday life.
