Where Does Postnasal Drip Come From?

Have you ever felt that annoying drip at the back of your throat that just won’t go away? That’s what we call postnasal drip, and it’s something many people deal with from time to time. But where does the drip actually come from? Let’s talk about what causes postnasal drip, why it happens, and what you can do about it.

What Is Postnasal Drip?

Postnasal drip happens when extra mucus from your nose or sinuses drips down the back of your throat. Normally, your nose produces mucus to keep things moist, trap dust, and fight germs. On average, adults produce about 1 to 1.5 liters of mucus every day — most of it goes unnoticed. But sometimes, your body makes more mucus than usual, or it becomes thicker, causing that uncomfortable drip.

Common Causes of Postnasal Drip

There are various factors that can lead to postnasal drip:

1. Colds and Flu
       When you catch a cold or the flu, your body produces extra mucus to fight off the infection. This can lead to postnasal drip.
2. Allergies
       Allergies affect about 30% of adults in the US, according to the American College of Allergy, Asthma, & Immunology. Allergens like pollen or dust trigger your body to make more mucus, which can cause postnasal drip.
3. Environmental Irritants
       Pollution, smoke, and strong smells can irritate your nose and cause more mucus to build up.
4. Weather Changes
       Cold or dry air can dry out or irritate your nasal passages, making your body produce more mucus.
5. Gastroesophageal Reflux Disease (GERD)
       Sometimes acid from the stomach can irritate your throat, leading to more mucus production and postnasal drip.

How Does Postnasal Drip Feel?

People with postnasal drip often describe a tickle or irritation in the back of their throat. You might find yourself coughing a lot, clearing your throat often, or feeling like you have a sore throat. It can also cause bad breath or make swallowing uncomfortable.

Simple Tips to Manage Postnasal Drip

·       Drink plenty of water to keep mucus thin.

·       Use saline nasal sprays to keep your nose moist.

·       Avoid irritants like smoke or strong perfumes.

·       Use a humidifier if the air in your home is dry.

·       Over-the-counter antihistamines might help if allergies are causing the problem.

Most postnasal drip cases clear up on their own or with simple treatments. But if your symptoms last longer than 10days, or if you have a fever, severe headaches, or thick green/yellow mucus, it’s a good idea to see a nose doctor.

Can Postnasal Drip Cause Sleep Apnea?

Postnasal drip doesn’t directly cause sleep apnea, but it can make things worse if you already have breathing problems duringsleep. Here’s how:

• Airway Obstruction: Mucus can build up in your throat and partially block your airway, which may interrupt breathing during sleep.
• Inflammation: Constant postnasal drip can cause swelling in your throat and nose, narrowing the airways.
• Sleep Position: People with postnasal drip might sleep on their backs, a position that can make airway blockage worse.
• Poor Sleep Quality: Coughing and throat irritation from postnasal drip can disturb your sleep and may worsen sleep apnea symptoms over time.

If you experience loud snoring, interruptions in your breathing during sleep, or persistent daytime fatigue, it's advisable to consult an ear, nose, and throat specialist.
