What can persistent postnasal drip lead to?

• A. Improved breathing patterns
• B. Coughing and throat irritation
• C. Decreased risk of sinus infections
• D. Reduced mucus production

Answer: (B)

Persistent postnasal drip means mucus from the nasal passages drains down the back of the throat. That drainage irritates the throat and stimulates the cough reflex, so you commonly see a chronic cough, throat irritation, frequent throat clearing, and sometimes hoarseness or a sore throat—especially when lying down or after exposure to triggers like allergies or a cold. This is why coughing and throat irritation is the best match. It doesn’t improve breathing patterns; in fact, nasal drainage can reflect nasal obstruction. It’s not about a decreased risk of sinus infections—postnasal drip is often associated with sinus or nasal inflammation, and it typically involves ongoing mucus production rather than reduced mucus.
