Jennifer Bergeron, MD, is a fellowship-trained laryngologist with specific interests in voice, swallowing, airway, and laryngeal cancer. She works closely with patients managing reflux alongside GLP-1 medications. As a contributing expert for RefluxRaft, she helps translate what she sees in clinic into practical, evidence-based guidance for patients navigating new or worsening nighttime symptoms.
In this post, Dr. Bergeron shares the routine she recommends to her GLP-1 patients dealing with reflux at night, why it happens, and the small, layered changes that tend to make the biggest difference.
Why does reflux get worse at night on a GLP-1?
GLP-1 medications work in part by slowing gastric emptying, which means food sits in the stomach longer. That extra pressure can make the lower esophageal sphincter more likely to relax at the wrong moment, letting stomach contents travel upward. Lying flat removes gravity's usual assist, which is why symptoms often show up or worsen after dark. Read more about why GLP-1s and acid reflux tend to go together →
"It's one of the most common concerns I hear from patients starting a GLP-1. The medication is doing exactly what it's supposed to do for their metabolic health, but it can also change how their body handles reflux, especially at night."
What routine does Dr. Bergeron recommend?
She recommends a layered approach rather than a single fix, built around four habits she walks through with nearly every GLP-1 patient managing reflux.
1. Watch food choices. Acidic and fibrous foods can be harder on a stomach that's already emptying more slowly.
2. Give your body time before bed. She recommends stopping food intake about 4 hours before lying down, giving the stomach a real head start on emptying before you're horizontal.
3. Elevate the head of the bed. A simple positional change that helps keep stomach contents where they belong through the night. Here's how much elevation actually helps →
4. Add an alginate after meals and at bedtime. As part of this broader routine, Dr. Bergeron has found that alginate therapy fits naturally into the plans she builds with patients managing reflux on GLP-1s. Learn how alginate therapy works →
"None of these steps are a magic fix on their own. But timing meals, positioning, and adding a physical barrier like RefluxRaft together, that's when patients tell me they're finally sleeping through the night again."
Why alginate, specifically?
Unlike antacids, which neutralize acid that's already present, alginates react with stomach acid to form a gel-like barrier, often called a "raft," that floats on top of stomach contents and helps physically block reflux from reaching the esophagus. It works locally in the stomach rather than systemically, which is part of why Dr. Bergeron recommends it as an add-on rather than a replacement for the routine changes above.

Does this protocol matter if you're not on a GLP-1?
Absolutely. GLP-1 use is simply one common trigger Dr. Bergeron sees for new or worsening nighttime reflux, but the same four-part routine, food timing, elevation, and an alginate after meals and before bed applies broadly to anyone whose reflux tends to flare once they lie down.

Where does Midnight Berry PM fit in?
For patients specifically looking for nighttime support, RefluxRaft's Midnight Berry PM pairs our alginate-based barrier with 1mg of melatonin, formulated for bedtime use as part of a routine like the one Dr. Bergeron describes. Read more about melatonin and reflux at night →.
Melatonin not your thing? RefluxRaft Lemon Ginger and Berry Burst formulas are also effective for nighttime symptom management.
Final Thoughts from Dr. Bergeron
"Reflux on a GLP-1 isn't a sign that something's wrong with the medication or with you, it's a known side effect that responds really well to a few consistent habits. I'd rather my patients build a routine that fits their evening than reach for one thing and hope it solves everything."
Frequently Asked Questions
Does taking a GLP-1 medication cause acid reflux?
GLP-1 medications can contribute to reflux by slowing gastric emptying, which increases pressure on the lower esophageal sphincter and makes reflux more likely, especially when lying down at night.
When should I take an alginate for nighttime reflux?
Dr. Bergeron recommends alginate therapy after meals and again at bedtime, timed alongside stopping food intake about 4 hours before lying down.
How much should I elevate the head of my bed for reflux?
Even a modest incline can help keep stomach contents from traveling upward overnight; RefluxRaft's guide on head elevation covers specific setups and how much of a difference each makes.
What foods should I avoid at night if I'm managing reflux on a GLP-1?
Acidic and fibrous foods tend to be harder to tolerate when gastric emptying is already slower, so Dr. Bergeron generally recommends limiting them, especially in the hours before bed.
Is Midnight Berry PM different from RefluxRaft's other formulas?
Yes, Midnight Berry PM combines the same alginate-based barrier with 1mg of melatonin, designed specifically to help to control the lower esophageal sphincter (LES) by increasing gastrin release and reducing stomach acid + supporting the natural sleep cycle.*
