Immune & Allergy

See how the immune system defends you — and how it can over-react, attack the body, or be too weak — in interactive 3D, then find care.

Conditions in this section

• Allergic Rhinitis (Hay Fever) — When the immune system over-reacts to harmless things like pollen or dust — very common and very manageable.
• Food Allergy & Anaphylaxis — When the immune system reacts to a food — usually mild, but sometimes a life-threatening emergency (anaphylaxis).
• Autoimmune Disease — When the immune system mistakenly attacks the body’s own tissues — many forms, and increasingly treatable.
• Lupus (SLE) — A whole-body autoimmune disease where the immune system attacks many tissues — manageable well with modern care.
• HIV — A virus that weakens the immune system — now a manageable long-term condition, and untransmittable when treated.
• Weak Immunity (Immunodeficiency) — When the immune system is too weak to fight infections properly — recognisable, and increasingly treatable.
