Understanding Acid Reflux: Symptoms, Causes, and Nighttime GERD

If you’ve ever experienced a burning sensation in your chest after a meal, you’re not alone. Acid reflux affects millions of people worldwide, and it can be more than just an occasional inconvenience. For many, symptoms worsen at night and impact sleep quality. Let’s explore what acid reflux is, how to recognize acid reflux symptoms, and why GERD symptoms at night can be particularly troublesome.

What Is Acid Reflux?

Acid reflux occurs when stomach acid flows back into the esophagus—the tube connecting your mouth and stomach. This backwash of acid irritates the lining of the esophagus and causes discomfort. When acid reflux becomes chronic, it can develop into GERD (gastroesophageal reflux disease).

Common Acid Reflux Symptoms

Recognizing acid reflux symptoms can help you address the problem before it becomes chronic. Symptoms often include:

A burning sensation in the chest (heartburn)
Regurgitation of food or sour liquid
Difficulty swallowing
Chronic cough or sore throat
A sensation of a lump in the throat

If you frequently experience these symptoms, especially after meals or when lying down, it could indicate GERD.

GERD Symptoms at Night

GERD symptoms at night can be especially disruptive. When you lie flat, stomach acid can more easily travel back into the esophagus. Nighttime GERD may cause:

Severe heartburn that wakes you up
Chronic cough or asthma-like symptoms
Sore throat or hoarseness in the morning
Disrupted, poor-quality sleep

Certain sleeping positions can worsen reflux. For example, stomach sleeping may negatively impact digestion and breathing.

Additionally, research shows that obesity can increase the risk of acid reflux and sleep disorders. You can learn more here: Obesity and Sleep.

Tips to Reduce Nighttime Acid Reflux

If you’re struggling with acid reflux symptoms at night, here are some practical steps you can take:

✅ Avoid eating large meals late in the evening

✅ Sleep with your upper body elevated

✅ Maintain a healthy weight

✅ Avoid alcohol, caffeine, and spicy foods before bed

✅ Sleep on your left side instead of your stomach

When to See a Doctor

Occasional acid reflux is common, but if you experience symptoms more than twice a week or they interfere with your daily life, consult a healthcare professional. Untreated GERD can lead to complications over time, including esophageal damage.
