Ozempic (GLP-1) Lawsuit — Free Case Review

Your Stomach Symptoms Were Real

If you took brand-name Ozempic, Wegovy, or Rybelsus and were diagnosed with a tested, documented stomach injury with an ER or hospital visit, you may qualify.

No Ozempic or other GLP-1 lawsuit has been settled, and no court or jury has found that these medications caused anyone's injury — the litigation is ongoing, with major expert-evidence rulings still ahead. Whether any individual has a claim depends on their own medical records and the law of their state.

Ileus and bowel obstruction are what happens when the intestine stops moving contents through — often ending in an emergency room, a nasogastric tube, and sometimes surgery. Unlike gastroparesis, these injuries are usually documented by imaging or an operative report at the time they happen, which means the proof is often already in your records. Federal GLP-1 stomach-injury cases are consolidated as MDL 3094 in the Eastern District of Pennsylvania, where 4,025 cases were pending as of October 2026. FDA added ileus to the Ozempic label in September 2023.

Reports submitted to FDA are not verified and do not establish causation.

What ileus and obstruction actually are

Both words describe the same lived experience from two different causes: nothing is moving through.

Ileus is when the intestine stops propelling contents forward even though nothing is physically blocking it — the muscle activity that normally pushes food along quiets down. Bowel obstruction is when something physically blocks the passage. A third term you may see in your chart is pseudo-obstruction: it looks exactly like a blockage on the scan and behaves like one, but no mechanical blockage is found.

What people describe is fairly consistent. Belly swelling that comes on over a day or two. Pain that goes from crampy to constant. Vomiting that will not stop, sometimes of material that clearly should have moved on long ago. No gas, no bowel movement, for a stretch of time that finally becomes frightening enough to go in. Then a CT scan, a nasogastric tube to decompress the stomach, nothing by mouth, and a few days of waiting to see whether it resolves on its own or needs an operation.

It is a genuinely dangerous condition. If this is happening to you right now, this page is not the priority — the emergency room is.

The drug worked. That’s what makes this hard.

Most people who end up here did not have a bad experience with these medications overall. It worked. The number on the scale moved, or the blood sugar did, and then this happened, and the two things have to somehow live in the same story.

You did what your doctor and the label told you was safe. Nothing about this is a consequence of why you took it. Whatever your reason was — diabetes, weight, both, or something you would rather not go into — it has no bearing on whether you were warned properly about this risk. That is the only question the litigation is actually about.

What makes these claims different from gastroparesis claims

This distinction is worth understanding, because it works in your favor.

On August 15, 2025, the court overseeing MDL 3094 ruled that gastroparesis claims must be supported by a properly performed gastric emptying study. That requirement, by its terms, is directed at gastroparesis diagnoses. Obstruction and ileus are diagnosed differently in the first place — by abdominal CT, by X-ray, by what a surgeon found in the operating room, by the hospital admission record itself. If you were admitted for an obstruction or an ileus, the objective documentation the court cares about was almost certainly generated at the time, without anyone needing to think about a lawsuit.

That is why the intake criteria for this track ask for gastric obstruction “confirmed with objective testing” rather than a specific named study. If you had a scan and a hospital stay, you likely already have what a review needs. Here is more on the testing question, including what happens if your diagnosis was gastroparesis instead.

The label history, stated plainly

In September 2023, FDA required ileus to be added to the Ozempic label as a post-marketing adverse reaction, and comparable intestinal-obstruction language followed across this class of drugs. That date matters in both directions, and honest coverage should say so.

For people injured before that change, the argument is that the warning was not there to read. For people injured after it, the manufacturers will argue the risk was disclosed — and they will also argue preemption, meaning that FDA reviewed this labeling repeatedly and made its own decisions about what it should say. Those arguments are pending and undecided. A hearing on the expert evidence behind warning adequacy, preemption, and whether these drugs are capable of causing ileus and obstruction is set for September 14–18, 2026 before Judge Karen S. Marston. We are not going to predict how it comes out.

Who may qualify today

• Brand-name Ozempic, Wegovy, or Rybelsus. Compounded or generic semaglutide, and Mounjaro, Zepbound or Trulicity, don’t fit today’s stomach-injury criteria — tell us anyway; criteria differ by track.
• Gastric or bowel obstruction confirmed by objective testing — imaging, endoscopy, or surgical findings — or gastroparesis confirmed by a gastric emptying study.
• Diagnosed while taking the medication, or within about 30 days of stopping.
• Diagnosed before December 31, 2024.
• An emergency room visit or hospital admission connected to the injury — for obstruction and ileus this is usually automatic.
• Age 75 or under at intake, and not already represented by another lawyer for this issue.
• Unsure which term is in your chart? Obstruction, ileus, and pseudo-obstruction are recorded inconsistently. Tell us what happened in your own words.

You are not suing your doctor

These claims are against the drug manufacturers — Novo Nordisk and Eli Lilly — not against your prescriber, the emergency physicians who treated you, the surgeon, or your pharmacy. The clinicians who documented your obstruction are, in practical terms, the people whose records help a claim most.
