Questions about Allergic Rhinitis

Do hormonal changes during menopause make allergic rhinitis symptoms worse?

Yes, hormonal changes during menopause may worsen allergic rhinitis symptoms by affecting immune and nasal tissue responses, though evidence is limited.

Full answer →
How do environmental exposures and microbiome changes affect allergic rhinitis?

Environmental exposures like air pollution and climate change disrupt the nasal microbiome and epithelial barrier, increasing allergic rhinitis risk, while microbial changes (dysbiosis) promote inflammation.
