Drainage in Throat (Post-Nasal Drip)

Post-nasal drip is the uncomfortable sensation of mucus accumulating or dripping down the back of your throat. While your nose and sinuses normally produce 1-2 quarts of mucus daily to keep nasal passages moist and trap particles, problems arise when production increases or mucus becomes thick and noticeable. This common condition affects millions and can result from allergies, infections, environmental irritants, or structural issues. The constant need to clear your throat, chronic cough, and sensation of something stuck in your throat can significantly impact quality of life. Understanding the underlying cause is key to finding relief, as treatment varies from simple home remedies to addressing chronic conditions like GERD or chronic sinusitis.
