Allergic Conditions We Diagnose and Manage

Allergic conditions occur when the immune system overreacts to substances that are normally harmless, such as certain foods, medications or environmental allergens. Depending on the condition, symptoms may affect the skin, airways, digestive system or other parts of the body, causing symptoms ranging from mild irritation to severe allergic reactions.

Drug Allergy

An adverse reaction to a medication triggered by the immune system. These reactions can range from mild to severe and, in some cases, can be life-threatening.

Food Allergy

Food allergies are immune system responses that occur when the body mistakenly identifies certain proteins in food as harmful. Reactions can range from mild to life-threatening.

Allergic Rhinitis

Allergic rhinitis, commonly known as hay fever, occurs when the immune system overreacts to allergens in the air, such as pollen, dust mites, animal dander, or mould spores.

Asthma

Asthma is a chronic inflammatory condition of the airways that can be triggered by allergens, respiratory infections, exercise or environmental irritants. It causes episodes of wheezing, coughing, chest tightness and shortness of breath, which may vary in severity over time.

Atopic Dermatitis/Eczema

Atopic dermatitis, commonly known as eczema, is a chronic skin condition characterised by inflamed, itchy, and red skin. It is one of the most prevalent skin disorders, particularly among children.

Urticaria

Commonly known as hives, it is a condition characterised by the sudden appearance of red, itchy welts on the skin. These welts can often appear and disappear within hours.

Angioedema

Angioedema

Angioedema is characterised by sudden swelling beneath the skin, most commonly affecting the face, lips, tongue, throat or limbs. It may occur alongside urticaria (hives) or develop on its own, and can sometimes interfere with breathing when the airways are involved.

Anaphylaxis

Anaphylaxis

Anaphylaxis is a severe, rapidly developing allergic reaction that can affect multiple body systems at the same time. It is a medical emergency that requires immediate treatment and is most commonly triggered by foods, medications or insect stings.

Immunodeficiencies in Adults

Immunodeficiencies in adults are conditions in which the immune system cannot respond effectively to infections. As a result, affected individuals may experience recurrent, severe or unusual infections that require specialist assessment and ongoing management.

Immune Dysregulation Disorders

Immune dysregulation disorders occur when the immune system fails to regulate itself properly, causing excessive or inappropriate immune responses. Depending on the underlying condition, this may increase the risk of autoimmune disease, recurrent infections, chronic inflammation or allergic disorders.
