Why does sinusitis cause postnasal drip?

Postnasal Drip is a common presentation of Sinusitis. The drainage may feel thin and clear, or thicker when mucus has become harder to move.

The sinuses normally make mucus that is carried into the nose and throat without much notice. During sinusitis, inflammation narrows the drainage passages and can make mucus linger. It may then collect and travel along the back of the nose rather than draining freely forward.

This can lead to throat clearing, a cough that is more noticeable when lying down, a hoarse feeling, or an unpleasant taste. These symptoms can also occur with allergies, a cold, irritants, or reflux, so postnasal drip alone does not identify the cause.

Drink fluids regularly and avoid smoke or strong scents that can further irritate the nose and throat. Gentle saline nasal rinsing or spray may help loosen mucus; use sterile, distilled, or previously boiled and cooled water for any rinse device.

Sleeping with your head slightly raised can reduce the sensation of drainage pooling in the throat. A pharmacist or clinician can help you choose suitable treatment if symptoms are persistent, especially if you have other medical conditions or use regular medicines.

Arrange a medical assessment if facial pain, nasal blockage, fever, or drainage is not settling, keeps returning, or is disrupting sleep and daily activity. Seek urgent care for swelling or redness around an eye, changes in vision, severe headache, confusion, a stiff neck, or trouble breathing.

Ask whether your pattern fits sinusitis or whether allergy, reflux, or another nasal condition should be considered. You can also ask how to use saline rinses safely, whether a nasal medicine is appropriate for you, and which changes should prompt follow-up.
