Symptoms, Treatment & Advice

What is an Allergy?

An allergy is a disorder of the immune system which, causes an exaggerated response within the body when you come into contact with a foreign substance, that would be harmless in most people. The contact can be with your skin, mouth, gullet (oesophagus), stomach, intestine or with the lining of your lungs. Substances in the environment that cause the response are known as allergens and someone who suffers a response to a particular allergen is said to be allergic to it. If you are allergic to a particular allergen you may suffer from a mild cough or a sneeze attack, but for others the symptoms can be much more severe, and can even lead to death. Almost any substance can be an allergen for someone.

Allergies are generally the body’s way of eliminating something it considers unsuitable. Allergies are responsible for many illnesses, especially in young children. If you think you have an allergy, you must contact your doctor who will help you to control the symptoms.

What causes allergies?

An allergy occurs when the allergen in question e.g. pollen, triggers a reaction in the body of the individual. When the allergen comes into contact with the body, the immune system believes that the specific allergen is harmful and so produces an antibody called IgE (E-class Immunoglobin) to fight it. This antibody then triggers chemicals, including one called histamine to be released from cells (called mast cells) in our skin, lungs, nose or intestine, causing the various symptoms of an allergic reaction.

The most common allergens are as follows:

• The house dust mite is one of the most common causes of allergies and no matter how clean your house every household will have them. The warmth and humidity in most homes is an ideal breeding environment for them, therefore our beds are a haven for them and a single mattress can contain up to 2 million mites. Mite allergy is caused by the mite faeces, which when inhaled cause breathing problems (asthma) or can irritate the skin on contact.
• Pollen from grass, trees and weeds is the second most common cause of allergies. Pollen allergies are usually seasonal. This type of allergy is called hay fever.
• The family pet is also a common cause of an allergy. The majority of U.K. households have a pet with 40% of asthmatic children being allergic to cats and/or dogs. It is usually the skin/fur (animal dander) which causes the problem. For more details on animal allergies click here.
• Insects bites such as those from bees or wasps.
• Foods and drinks, such as milk, eggs, fish, wheat, soy, citrus fruits, seafood and peanuts. Colourings and preservatives can also trigger attacks. For more information on food allergies click here.
• Cosmetics, toiletries, jewellery and washing powders all contain common allergens. Symptoms are typically identified by an itchy, red rash.
• Mould and mould fungus. Mould grows in damp conditions and is obvious in houses that have damp patches on the walls or black mould around window seals or bathrooms. Mould spores can also be found in the soil of house plants.
• Latex and rubber.
• Certain medicines and drugs, such as antibiotics and anaesthetics.

What symptoms are linked with an allergy?

There are many different types of allergies and the symptoms can vary according to what the allergen is, how severe the reactions and what part of the body is involved.

Common symptoms of an allergy may include:

• Attacks of sneezing or a runny nose (usually key symptoms of an allergy).
• Blocked nose and sinus pain.
• Watery, itchy eyes.
• Itchy, red rashes or inflamed skin (eczema or dermatitis).
• Number of raised bumps or weals surrounded by red skin, which can be itchy. This is known as urticaria, hives or nettle rash. Urticaria can be caused by allergies to animals, foods, bee stings or medicines.
• Coughing
• Swelling of the lips and tongue.
• Diarrhoea
• Sickness and vomiting.
• Itchy, sore throat.
• Wheezing and shortness of breath (asthma attacks).
• Anaphylaxis, the most extreme of allergic reactions.

Treatment

How are allergies treated?

Prevention is the key in allergy sufferers, so if you know you have an allergy to something you should make the effort to avoid or reduce contact with the specific allergen. To control allergy symptoms you should try the following tips:

• Remove all carpets and switch to wooden floors, tiles or vinyl to reduce the presence of the house dust mite.
• Vacuum soft furnishings frequently or switch to leather or vinyl sofas and chairs.
• Keep your house well ventilated (open windows when cooking and bathing) to reduce humidity levels and prevent mould from forming.
• Wash bedding weekly at a temperature of 60°c or above to kill off any allergens.
• Buy special mattresses and pillow coverings that are resistant to the dust mite.
• Regularly dust and vacuum your house to reduce the population of house dust mites. Ensure your vacuum cleaner has the British Allergy Foundation seal of approval to remove dust mites and cat and dog allergens.
• Put your child’s soft toys in a bag in a freezer for at least 12 hours every month or wash them frequently at high temperatures to kill off dust mites.
• Don’t buy pets but if you do have them, keep them outside and never allow them in a bedroom.
• Use non-scented and hypoallergenic products.
• Use gloves when handling chemicals, solvents and detergents.

There are also drugs available which can ease an allergic reaction. The most common drugs used for allergy symptoms are antihistamines and steroids, which come in the form of nasal sprays, creams or tablets. The exact treatment depends on the area of the body involved.
