Does a GLP-1 cause burping?

Yes. Wegovy and Zepbound list eructation, the medical term for burping, in their reaction tables. Those rows do not describe the smell of the burps.

What the product trials found

These are separate trials, so their rates cannot rank the medicines.

How these findings apply

The compound summaries below omit some reactions found in full product labels. That is why an empty summary row should not be read as a label finding.

The FDA snapshot also includes reports filed under eructation. Those reports do not establish what caused the symptom in one person.

Product labels and FDA report summaries answer different questions. Keep each finding tied to its product; a report share is not a rate among everyone taking the medicine.

These tables summarize selected reaction entries. A missing entry does not mean the full label or all published studies omit it. A summary does not replace the full prescribing information. A pharmacist or clinician can review the complete label alongside the rest of a person’s medicines.

What people reported to the FDA

The first table summarizes labels and published trials. This table shows reports filed with the FDA after the medicines went on sale. Each percentage is the share of reports for that product that mention this symptom—not the share of patients who experienced it.

Each GLP-1 brand in the FDA snapshot, and what share of its reports names this symptom.
ProductShare of its own reportsAll reports
Ozempicsemaglutidebelow 2.3% of Ozempic reports66,161 reports
Trulicitydulaglutidebelow 2.1% of Trulicity reports88,332 reports
Rybelsussemaglutidebelow 2.1% of Rybelsus reports7,379 reports
Wegovysemaglutidebelow 2.0% of Wegovy reports21,044 reports

Mounjarotirzepatide1.7% of Mounjaro reports93,975 reports
Victozaliraglutidebelow 1.7% of Victoza reports44,086 reports

A row reading “below” is not a zero. The snapshot keeps each product’s 25 most-reported terms, so a term missing from that list was either never reported or reported outside the stored list. The cutoff provides an upper bound, not an exact count. Read from FDA on 2026-08-17.

Reports are not rates and a report is not proof the drug did it. How to read this data, and the questions it answers on its own.

3Read deeperWhy it happens, when it appears, and what the evidence shows

Does eructation mean sulfur burps?

Eructation means burping or belching. The label row does not identify an odor, and the FDA term shown here does not separate sulfur burps from other belching.

A finding about burping should not be presented as a measurement of sulfur-smelling burps. That more specific description is not what these rows record.

What the tables say about timing

The reaction tables checked here do not give a timetable for burping to begin or stop. Their percentages describe study groups, not how long one person will have symptoms.

The FDA snapshot counts reports mentioning a term. It does not provide a recovery timeline.

What this page does and does not establish

Read the label findings and the report snapshot separately.

What this page does and does not establish
The claimWhat the evidence shows
No label lists burping.Incorrect. Wegovy and Zepbound list eructation. A short compound summary can omit a row that appears in the full label.
Tirzepatide causes more burping than semaglutide.The report shares cannot establish that. They do not count everyone who used each medicine.
A dashed report row means no cases occurred.It means the term was not in that product’s stored top terms. The count may be below the cutoff rather than zero.
The reports confirm sulfur-smelling burps.The general eructation term does not distinguish odor, so that claim is not supported.

When to discuss burping with a clinician

Report persistent or troubling symptoms, including any pain, vomiting or trouble keeping fluids down. Those details matter more than the label term alone.

ClinicianSevere or lasting abdominal pain needs medical attention. A clinician can assess the symptoms and decide whether treatment needs to change.

Common questions

Are sulfur burps a listed side effect of Zepbound or Mounjaro?

Zepbound lists eructation, meaning burping. That entry does not describe a sulfur smell.

Mounjaro has its own label. Zepbound’s trial figures should not be presented as Mounjaro results. The FDA snapshot uses a general belching term for reports about both products.

Why do the two measured rows matter if the numbers are small?

The stored snapshot includes eructation among the top terms for two products. That describes which reports are visible in this extract; it does not rank the medicines by risk.

Is this the same as the gastroparesis question?

No. Belching and delayed stomach emptying are different report terms. A report containing one does not establish the other, and a report alone does not prove a diagnosis.

What would actually answer this?

The product-label tables already answer whether burping was reported during those trials. They keep the placebo results beside the treatment results.

They do not establish a cause for one person or answer the more specific question about sulfur odor.
