Can Acid Reflux Cause Coughing? A Detailed Explanation by mr.hotsia
For more than 30 years I have traveled throughout Thailand, Laos, Cambodia, Vietnam, Myanmar, India, and many other parts of Asia 🌏. I am mr.hotsia, and during my long journeys I have tasted spicy dishes, sour soups, oily curries, fermented foods, and late night snacks from countless local markets. Along the way, I have met many travelers and locals who experience coughing that is not caused by a cold or infection but by acid reflux.
A common question they ask is:
“Can acid reflux cause coughing?”
The answer is yes. Acid reflux can definitely cause coughing. In fact, it is one of the most common symptoms of silent or nighttime reflux. This article explains how acid reflux causes coughing, what the cough feels like, and how to reduce it, based on both medical knowledge and my personal experience across Asia.
How Acid Reflux Causes Coughing
Acid reflux happens when stomach acid flows upward into the esophagus. Sometimes the acid travels even higher into the throat or airways. When this happens, the acid irritates the sensitive tissue and triggers a cough reflex.
Here are the main ways reflux leads to coughing.
1. Acid Irritates the Throat
When acid reaches the throat, it causes:
-
Irritation
-
Inflammation
-
Burning sensation
-
Scratchy feeling
This irritation often causes a dry cough that gets worse when lying down.
I experienced this many times when I ate late night food in Thailand or Laos.
2. Acid Reaches the Voice Box (Larynx)
This condition is called laryngopharyngeal reflux (LPR).
When acid touches the voice box:
🗣️ The voice becomes hoarse
😮💨 Breathing feels uncomfortable
😵 A cough appears suddenly
During my travel in Myanmar, after eating spicy noodles at night, I woke up coughing because acid reached my throat and larynx.
3. Acid Enters the Airway
Sometimes small amounts of acid can reach the airway. The body reacts by coughing to protect the lungs. Even tiny droplets of acid can trigger coughing easily.
This type of cough often happens:
🌙 At night
🛌 When lying down
🤢 After regurgitation
🧪 After spicy or acidic meals
4. Post Acid Mucus Production
When the throat gets irritated by acid, the body produces extra mucus to protect the tissue. This leads to:
-
Throat clearing
-
Wet cough
-
Feeling of mucus stuck in the throat
Many people confuse this with allergies, but it often comes from reflux.
What a Reflux Cough Feels Like
People describe their reflux cough differently, but the symptoms are usually similar:
😮💨 Dry, tickling cough
🔥 Burning in the throat
🪵 Scratchy feeling
🗣️ Hoarse voice
🤢 Coughing after eating
🌙 Coughing at night or early morning
📌 Feeling like something is stuck in the throat
I personally experienced this after drinking strong Vietnamese coffee in the evening. The acid triggered throat irritation that caused coughing for hours.
Why Reflux Coughing Happens More at Night
Nighttime reflux is a major cause of chronic coughing. When lying down:
-
Gravity no longer holds acid down
-
Acid moves into the throat easily
-
Swallowing decreases
-
Saliva production drops
-
Acid stays longer in the throat
These natural changes allow more irritation to occur.
During long travel days when I ate dinner late and went to bed immediately, I always experienced nighttime coughing caused by reflux.
Common Triggers of Reflux Coughing
Based on my experiences traveling through Asia, these foods and habits cause the most reflux coughing:
🌶️ Chili heavy foods
🍛 Indian masala curries
🍜 Late night noodles
🥤 Carbonated drinks
☕ Strong coffee
🍺 Alcohol
🍟 Fried foods
🍅 Tomato based dishes
🍋 Acidic fruits
🛌 Lying down too soon after eating
All these can irritate the esophagus and throat.
How to Reduce Coughing From Acid Reflux
Here are the methods that helped me during my travels:
🍵 Drink warm ginger tea
Soothes the throat and reduces irritation.
🚶 Walk 10 to 20 minutes after eating
Prevents acid from rising.
🌙 Avoid eating 2 to 3 hours before bedtime
One of the best ways to stop nighttime reflux.
🛌 Sleep with your upper body elevated
Helps acid stay in the stomach.
🍽️ Eat smaller meals
Reduces stomach pressure.
💧 Drink water slowly
Washes acid out of the throat.
🍌 Eat soothing foods
Bananas, cucumbers, rice, boiled vegetables.
☕ Avoid evening caffeine
Especially strong Vietnamese coffee.
🍺 Reduce alcohol
Alcohol relaxes the esophageal muscle.
When Reflux Coughing Should Be Taken Seriously
Consider medical evaluation if you have:
-
Persistent cough for weeks
-
Hoarse voice for long periods
-
Difficulty swallowing
-
Chest pain
-
Coughing every night
-
Regurgitation with coughing
These symptoms may indicate GERD or silent reflux (LPR).
