Ozempic Side Effects
& Symptoms That
Qualify for a Lawsuit

Reviewed by: ClaimCheckUSA Medical Review TeamLast updated: March 26, 2026

Not all Ozempic side effects qualify for a lawsuit. Common side effects like mild nausea are expected and disclosed. The lawsuits focus on serious, undisclosed gastrointestinal complications — particularly gastroparesis and intestinal obstruction — that Novo Nordisk and Eli Lilly allegedly failed to adequately warn patients about.

Serious Side Effects That May Qualify

Gastroparesis (Stomach Paralysis)

Severe
  • Chronic nausea and vomiting
  • Feeling full after eating a small amount
  • Bloating and abdominal pain
  • Blood sugar fluctuations
  • Malnutrition and weight loss

This is the primary qualifying condition for the Ozempic lawsuit.

Intestinal Obstruction (Ileus)

Severe
  • Inability to pass gas or have bowel movements
  • Severe abdominal cramping
  • Vomiting of fecal matter
  • Abdominal distension
  • Requires emergency surgery in many cases

FDA added ileus warning to Ozempic label in 2023.

Pancreatitis

Severe
  • Severe upper abdominal pain radiating to the back
  • Nausea and vomiting
  • Fever and rapid pulse
  • Tenderness when touching the abdomen

Acute pancreatitis has been reported in GLP-1 users.

Aspiration Pneumonia

Serious
  • Coughing up food or stomach contents
  • Chest pain
  • Difficulty breathing
  • Fever and chills

Caused by vomiting stomach contents into the lungs.

Acute Kidney Injury

Serious
  • Decreased urination
  • Swelling in legs and ankles
  • Fatigue and confusion
  • Shortness of breath

Caused by severe dehydration from prolonged vomiting.

Common Side Effects (Usually Do Not Qualify)

The following are common, expected side effects of Ozempic and similar GLP-1 drugs. These are disclosed in the drug's labelling and generally do not qualify for a lawsuit on their own:

Nausea (very common, especially when starting)
Vomiting
Diarrhoea
Constipation
Stomach pain
Decreased appetite
Heartburn / acid reflux
Burping
Fatigue
Headache

Frequently Asked Questions

Which Ozempic side effects qualify for a lawsuit?
The primary qualifying conditions are gastroparesis (stomach paralysis), intestinal obstruction/ileus, severe pancreatitis, and aspiration pneumonia. Common side effects like nausea and diarrhoea alone typically do not qualify unless they led to hospitalisation or a more serious diagnosis.
How do I know if I have gastroparesis from Ozempic?
Gastroparesis is typically diagnosed through a gastric emptying study. Symptoms include chronic nausea, vomiting, feeling full quickly, bloating, and abdominal pain. If you experienced these symptoms while taking Ozempic and were hospitalised or diagnosed, you may qualify for a lawsuit.
Can I still file a lawsuit if I only had nausea?
Nausea alone is unlikely to qualify unless it was severe enough to cause hospitalisation, significant weight loss, or led to a more serious diagnosis like gastroparesis or kidney injury. Contact an attorney to review your specific situation.
What medical records do I need for an Ozempic lawsuit?
You'll need prescription records showing you took Ozempic, Wegovy, or a similar GLP-1 drug, plus medical records documenting your diagnosis (e.g., gastroparesis diagnosis, hospital admission records, gastric emptying study results). Your attorney will help gather these.
