Weight Loss & Diabetes Drug Lawsuits Guide

What are the Claims Against Diabetes and Weight Loss Drugs?

Weight loss and diabetes drug lawsuits - victims of stomach paralysis, pancreatitis, pancreatic cancer and other conditions may qualify.

Recent claims have brought attention to potential health risks associated with popular weight loss and diabetes drugs like Ozempic (semaglutide), Wegovy (semaglutide), Mounjaro, and others. The primary allegation in these lawsuits is that these drugs, which belong to a class called GLP-1 agonists, may cause severe gastrointestinal issues like gastroparesis (stomach paralysis), ileus (intestinal blockage), and other serious health problems.

However, many other serious conditions may be linked to drugs like Ozempic, Mounjaro, and Wegovy, including:

  • Stomach paralysis (gastroparesis)
  • Pancreatitis
  • Pancreatic cancer
  • Persistent vomiting
  • Persistent nausea and diarrhea
  • Stomach not working

What Drugs May Cause These Problems?

Weight loss drugs and diabetes drugs are increasingly popular — and some of the drugs potentially linked to these serious health problems are "household names." Drugs involved in recent claims include:

  • Ozempic
  • Wegovy 
  • Mounjaro
  • Saxenda
  • Trulicity
  • Rybelsus

Ozempic, Wegovy, and Rybelsus are brand names of semaglutide.

IMPORTANT: As of January 2024, it is alleged, and not yet proven, that the drugs listed above may cause serious health problems like gastroparesis, pancreatitis, pancreatic cancer, and others. These drug manufacturers have strongly denied any potential liability or wrongdoing, and there have been no settlements in these cases. Riddle & Brantley is actively investigating these claims and we will continue to monitor scientific developments as research continues. Please stay tuned to our website for the latest details.

Health Problems Potentially Linked to Diabetes and Weight Loss Drugs

Several potentially serious health problems may be linked to popular weight loss and diabetes drugs like Wegovy, Ozempic, Mounjaro, and others. These conditions include, but are not limited to:

Gastroparesis (Stomach Paralysis)

Many of these claims and lawsuits allege that these drugs cause stomach paralysis, a condition that is scientifically known as "gastroparesis."

Gastroparesis is a condition, sometimes called "stomach paralysis," where the stomach's ability to empty its contents is impaired. In severe cases, it can lead to malnutrition, severe dehydration, and other complications. This condition has been a central point in the Ozempic, Wegovy, and other lawsuits, where plaintiffs claim that after using drugs like Ozempic and Mounjaro, they suffered from severe vomiting, stomach pain, and other symptoms indicative of gastroparesis.

Symptoms of Gastroparesis

According to the Mayo Clinic, symptoms of gastroparesis (stomach paralysis) may include:

  • Vomiting
  • Nausea
  • Abdominal bloating
  • Abdominal pain
  • A feeling of fullness, even after eating just a few bites
  • Vomiting undigested food even just hours earlier
  • Acid reflux
  • Blood sugar (glucose) level changes
  • Lack of appetite
  • Weight loss and malnutrition

IMPORTANT: If you have experienced any of the symptoms above or believe you may be suffering from stomach paralysis (gastroparesis), seek immediate medical attention.


Another health problem potentially linked to popular weight loss and diabetes medications is pancreatitis. Pancreatitis is an inflammation of the pancreas, an organ located behind the stomach that plays a crucial role in digestion and blood sugar regulation. This condition can be acute, presenting suddenly with severe symptoms, or chronic, developing over time and leading to persistent problems. Causes of pancreatitis may include gallstones, heavy alcohol consumption, and, potentially, use of certain prescription drugs like Ozempic and Wegovy, among others.

Symptoms of Pancreatitis

According to the Cleveland Clinic, symptoms of acute pancreatitis may include:

  • Abdominal pain (primary symptom)
  • Nausea and vomiting
  • Fast heart rate
  • Fast, shallow breathing
  • Fever

Chronic pancreatitis may include additional symptoms, including:

  • Indigestion and pain or discomfort after eating
  • Loss of appetite or unintended weight loss
  • Fatty bowel movements that leave oily residue in the toilet
  • Lightheadedness (from low blood pressure)

IMPORTANT: If you have experienced any of these symptoms or believe you may be suffering from acute or chronic pancreatitis, seek immediate medical attention.

Pancreatic Cancer

One of the more frightening conditions potentially linked to popular weight loss and diabetes drugs is pancreatic cancer. Pancreatic cancer is a serious form of cancer that begins in the pancreas, an organ that lies behind the stomach and plays a crucial role in digestion and blood sugar regulation. This type of cancer is particularly dangerous because it often goes undetected until it's at an advanced stage, making treatment more challenging.

Factors that may increase the risk of developing pancreatic cancer include smoking, having chronic pancreatitis, a family history of the disease, certain genetic conditions, and, potentially, use of certain prescription drugs like Ozempic, Wegovy, Rybelsus, Trulicity, and others.

Symptoms of Pancreatic Cancer

According to the Mayo Clinic, symptoms of pancreatic cancer may include:

  • Belly pain that spreads to the sides or back
  • Loss of appetite
  • Weight loss
  • Jaundice, a yellowing of the skin and/or whites of the eyes
  • Light-colored or floating stools
  • Dark-colored urine
  • Itching
  • Newly diagnosed diabetes, or diabetes that's getting harder to control
  • Pain and swelling in an arm or leg, potentially caused by a blood clot
  • Tiredness, weakness, and fatigue

IMPORTANT: If you have experienced any of these symptoms, or are concerned you may have pancreatic cancer, seek immediate medical attention.

These lawsuits allege that the manufacturers of these diabetes and weight loss drugs failed to provide adequate warnings about the severity of these side effects. For instance, in one of the lawsuits, a plaintiff claimed that after being prescribed Mounjaro, they developed a painful "paralyzed" stomach (gastroparesis), leading to severe vomiting, diarrhea, dehydration, and even kidney failure. The complaint suggests that the drug makers were aware of these risks but did not sufficiently warn the users or the medical community.

In legal terms, this is known as "failure to warn." 

FDA Warnings and Concerns

In response to these concerns, the FDA updated the warning labels for drugs like Ozempic in September 2023 to include risks of intestinal blockage and ileus. Research conducted by experts, including a study by the Mayo Clinic on a similar drug, found that these medications significantly slowed down digestion. These findings are crucial as they provide scientific backing to the claims made in the lawsuits.

Manufacturers' Response to Allegations

Manufacturers like Novo Nordisk and Eli Lilly, alleged to have failed to warn consumers about the potential risks of drugs like Ozempic and Wegovy, have strongly denied any liability or wrongdoing. In a recent statement by Novo Nordisk, manufacturer of Ozempic and Wegovy, the company said that “Gastrointestinal (GI) events are well-known side effects of the GLP-1 class. For semaglutide, the majority of GI side effects are mild to moderate in severity and of short duration. GLP-1’s are known to cause a delay in gastric emptying, as noted in the label of each of our GLP-1 RA medications. Symptoms of delayed gastric emptying, nausea and vomiting are listed as side effects."

Nevertheless, claims continue to grow, with many consumers taking legal action.

Current Status of Lawsuits

As of early 2024, numerous lawsuits have been filed, with plaintiffs seeking compensation for their suffering and medical expenses due to the alleged side effects of these drugs. A motion to centralize all Ozempic and Mounjaro gastroparesis lawsuits in the U.S. District Court for the Western District of Louisiana for coordinated pretrial proceedings is under consideration.
