Runny Nose Causes
When dealing with a constantly dripping nose, understanding the runny nose causes, the various conditions and factors that trigger excess nasal discharge, also known as rhinorrhea, can save you time and frustration. A runny nose isn’t just a nuisance; it often signals an underlying issue that your body is trying to clear.
Key Triggers to Watch
One of the biggest culprits is Allergies, an immune response to pollen, dust, pet dander, or mold that inflames nasal passages. When allergens hit, histamine floods the tissue, pulling fluid into the nose and causing that watery stream. Another frequent source is the Common Cold, a viral infection that thickens mucus and stimulates the nasal lining. Even though a cold usually clears in a week, the congestion can linger and keep the nose running.
We also see Sinus Infection, bacterial or viral inflammation of the sinus cavities that blocks drainage and forces mucus out the nose. When the sinuses swell, pressure builds and the body pushes fluid out to relieve it. Environmental irritants such as smoke, strong scents, or sudden temperature changes act as non‑allergic triggers; they irritate the lining and provoke a reflexive runny nose.
Beyond these, certain medicines can be a hidden cause. Decongestant overuse, blood pressure pills, or even hormonal shifts during pregnancy can tip the balance and produce a drip. Recognizing whether a drug is behind your symptoms often means checking the medication’s side‑effect list and consulting a pharmacist.
Below you’ll find a curated set of articles that dive deeper into specific treatments, medication comparisons, and practical tips for managing nasal discharge. Whether you’re battling allergies, a stubborn cold, or a sinus infection, the collection offers clear guidance to help you decide the best next step.
