Got rhinitis but why are you coughing too? A stuffy nose alone is bad enough, but when your throat gets scratchy and you start coughing, it's absolutely maddening. I suffered from rhinitis for years, and when the coughing kicked in, I couldn't sleep at night—I thought I was losing my mind. But did you know it's not just your nose causing this? Here's the fact: coughing from rhinitis is caused by a mix of factors. Let's break it down one by one.
Cause 1: Postnasal Drip – Mucus Dripping Down Your Throat Triggers Cough?
With rhinitis, your nose constantly produces secretions. The problem is that not all of it comes out of your nose—some drips down the back of your throat. This is called 'postnasal drip,' and it irritates the pharyngeal mucosa, triggering the cough reflex. It gets worse when you lie down, so your cough explodes at night. In my case, when I woke up in the morning, I felt something stuck in my throat and kept coughing to get it out. That was all due to postnasal drip.
Cause 2: Allergens Attack Your Throat Mucosa Too?
One of the main causes of rhinitis is allergens (dust mites, pollen, pet dander, etc.), and these allergens don't just irritate your nasal mucosa. Research shows that allergen-induced nasal irritation can increase the sensitivity of the pharyngeal mucosa, leading to coughing. In other words, the allergic reaction that starts in your nose affects your throat too. I have a dust mite allergy, and just cleaning would stuff up my nose and make my throat itchy, causing coughs. It wasn't just my nose—it was my sensitized throat mucosa.
Cause 3: Airway Hyperresponsiveness – Could Be Pre-Asthma?
This is the scariest part: rhinitis can cause airway hyperresponsiveness, which can lead to asthma or airway hyperreactivity. In fact, many rhinitis patients complain of coughing, and it's not from the nose but from the airways themselves becoming sensitive. If you cough when exposed to cold air or get short of breath and cough after exercise, you should suspect airway hyperresponsiveness. I initially thought it was just rhinitis, but after a lung function test, I was diagnosed with airway hyperresponsiveness. I was shocked to hear that leaving it untreated could develop into asthma.
So What Should You Do? Find the Cause First!
The conclusion is simple. If you have a cough after rhinitis, you need to accurately investigate whether the cause is your nose or airway hyperresponsiveness. If it's your nose, focus on treating rhinitis; if it's airway hyperresponsiveness, you might need asthma medication. Like me, just taking rhinitis pills could waste time. The fastest way is to visit both an ENT and a pulmonologist to comprehensively test for postnasal drip, allergies, and airway hyperresponsiveness.
One more personal experience: when I only took rhinitis medication, my cough didn't improve at all. But after finding the cause and treating both postnasal drip and airway hyperresponsiveness, my cough decreased significantly. Don't just endure it—find the cause and get proper treatment. Let's end those sleepless nights from coughing for good.
