Introduction[edit | edit source]

Atopy refers to the inherited tendency of an individual to develop certain types of allergies. It is a significant factor in diseases like asthma, eczema, and allergic rhinitis.

Genetic Basis[edit | edit source]

Atopy is strongly linked to genetics, with a higher likelihood in individuals who have parents or siblings with allergic diseases.

Common Atopic Conditions[edit | edit source]

Atopic individuals are more prone to develop:

Asthma - A respiratory condition marked by spasms in the bronchi of the lungs
Eczema (Atopic Dermatitis) - A skin condition causing itchy and inflamed skin
Allergic Rhinitis - Allergies characterized by sneezing, congestion, and a runny nose

Pathophysiology[edit | edit source]

Atopy involves an abnormal immune response, where the body overreacts to harmless substances such as pollen, dust mites, or certain foods. This reaction is mediated by Immunoglobulin E (IgE) antibodies.

Diagnosis[edit | edit source]

Diagnosis of atopy can involve:

Family and personal medical history
Skin prick tests
Blood tests to measure IgE levels

Management and Treatment[edit | edit source]

While there is no cure for atopy, its symptoms can be managed through:

Avoidance of known allergens
Use of antihistamines and corticosteroids
Immunotherapy in some cases

Epidemiology[edit | edit source]

The prevalence of atopic diseases has been increasing globally, making it a significant public health concern.
