Key points

Why it happens

When your stomach empties more slowly, it stays fuller for longer, which puts pressure on the valve at the top of the stomach.

What helps

TryWhy
Smaller mealsLess pressure on the stomach
Eat 3 hours before bedLess in your stomach when you lie down
Raise the head of your bedGravity keeps acid down
Go easy on trigger foodsFatty food, spicy food, chocolate, coffee, alcohol, citrus
Don’t lie down after eatingStay upright for a while
Loose waistbandsLess pressure on your stomach

Medicines

Antacids and other over-the-counter reflux medicines are widely used. Ask your pharmacist which is right for you, and whether any affect your other medicines — it matters more than usual on a GLP-1, because slowed stomach emptying already affects how other things you swallow are absorbed.

When to call a doctor

A real-life example

Paula, 53, woke with heartburn most nights on Wegovy. She moved dinner to 6 pm, added a wedge pillow, and cut back on late-night wine. Within two weeks, most nights were heartburn-free.

Common questions

Is heartburn on Ozempic normal?

It’s a known side effect for some people. Tell your prescriber if it’s frequent.

Can I take Tums on a GLP-1?

Many people do. Check with your pharmacist about timing with other medicines.

Does reflux mean I should lower my dose?

Only your prescriber can decide. Mention it at your next check-in.
