Could It Be an Allergy? Common Signs and How to Find Answers

Allergies are extremely common and affect people of all ages. They occur when the immune system reacts to something that is usually harmless, such as certain foods, pollen, pet hair or dust. Instead of ignoring these substances, the immune system treats them as a threat and releases chemicals like histamine, which are responsible for the symptoms people experience. For some, these symptoms are mild and occasional, while for others they can be persistent, uncomfortable and disruptive to daily life. 

There are many different types of allergies, and they can show up in different ways depending on the trigger. Food allergies are among the most well-known and occur when the immune system reacts to proteins in foods such as nuts, milk, eggs, wheat or shellfish. Reactions can range from bloating or stomach pain after eating, to skin rashes, swelling or breathing difficulties. Environmental allergies are also very common and are often referred to as hay fever or allergic rhinitis. These are triggered by substances in the air, including pollen from trees and grasses, dust mites, mould spores or animal dander (skin cell proteins, hair and fur), and typically cause sneezing, nasal congestion, itchy eyes and fatigue. 

Some people are specifically allergic to animals, particularly cats and dogs. These reactions are caused by proteins found in an animal’s skin flakes, saliva or urine rather than the fur itself. Others may experience allergic reactions to moulds and fungi, which tend to thrive in damp environments and can trigger respiratory symptoms, headaches or skin irritation.

Insect allergies, such as reactions to bee or wasp stings, are less common but can be serious in some individuals. Certain medications and chemicals can also cause allergic responses, leading to rashes, swelling or breathing problems. 

The signs of an allergy are not always obvious and can sometimes be mistaken for other conditions. Common symptoms include sneezing, a runny or blocked nose, itchy or watery eyes, coughing, wheezing, skin rashes, hives or flare-ups of eczema. Digestive symptoms such as nausea, abdominal pain, diarrhoea or vomiting can also occur, particularly with food-related allergies. In more severe cases, swelling of the lips, face or throat may develop and require urgent medical attention. If symptoms are recurring, unexplained or affecting quality of life, identifying the cause is an important step towards managing them effectively. 

Allergy testing can help remove the guesswork. One of the most reliable ways to investigate allergies is through a blood test that measures allergen-specific IgE antibodies. These antibodies are produced by the immune system in response to substances to which it is sensitised to. By measuring IgE levels to a wide range of allergens, blood testing can identify exactly what your body is reacting to. This can be particularly helpful if you have multiple symptoms, are unsure what is triggering them, or want clarity before making long-term lifestyle or dietary changes.
