Active case

Many people have turned to the increasingly popular semaglutide drug Ozempic® as a way to lose weight. This drug mimics hormones that reduce appetite and moderate insulin release. However, many expected and unexpected risks are associated with using Ozempic, and these risks can vary in severity. Learn about gastrointestinal issues and other alleged Ozempic side effects.

Wegovy Updates


There have been several recent updates in Wegovy and Ozempic litigation. As of March 1, 2024, Judge Gene E.K. Pratter in the Eastern District of Pennsylvania presides over 58 personal injury lawsuits regarding obstruction, intestinal blockages and gastroparesis in MDL 3094 . Motley Rice was the first law firm in the country to file a Wegovy lawsuit, with attorney Jonathan Orent arguing for the assignment of an MDL in the Eastern District of Pennsylvania.

Unexpected Ozempic weight loss side effects

Ozempic is a GLP-1 agonist prescription medication manufactured by Novo Nordisk. It was approved by the U.S. Food and Drug Administration (FDA) in 2017. Also known by its generic name, semaglutide, this Type 2 diabetes drug, which at times is prescribed off-label for weight loss, works by reducing appetite, sugar levels and glucose production, similar to its sister drug, Wegovy®.

Ozempic manufacturers disclosed some side effects on the medication guide and prescribing information. However, some reports of severe gastrointestinal events and other health problems were not included on the warning label. People are filing Ozempic lawsuits that claim Novo Nordisk knew or should have known about the risk of severe side effects like gastroparesis, gastroenteritis, intestinal blockage, blood clots and other severe health problems but failed to warn users.

Stomach paralysis aka gastroparesis (not on warning label)

Also known as stomach paralysis, gastroparesis slows down the movement of stomach muscles, preventing the stomach from emptying properly. This can lead to many debilitating symptoms and alleged Ozempic side effects, including:

  • Abdominal bloating
  • Abdominal pain
  • Acid reflux
  • Decreased quality of life
  • Lack of appetite
  • Nausea
  • Severe dehydrationa
  • Vomiting

Gastroparesis can be a very serious medical condition for which there is no cure. Motley Rice is currently representing a woman who developed severe gastroparesis after taking semaglutide medication. This ultimately led to painful cramping, nausea, and vomiting that required hospitalization.

Gastroenteritis (not on warning label)

Gastroenteritis occurs when the intestines and stomach become inflamed . Gastroenteritis, when viral, is also commonly referred to as the stomach flu. However, gastroenteritis may also be caused by certain types of medication . Some of the most common symptoms associated with gastroenteritis allegedly caused by Ozempic include:

  • Dehydration
  • Diarrhea
  • Fever
  • Headaches
  • Muscle aches
  • Nausea
  • Stomach cramps
  • Vomiting

Gastroenteritis can be far more severe than mild nausea and vomiting. The side effects of dehydration may require hospitalization, and continued symptoms can make it difficult to complete daily tasks.

Ileus (intestinal blockages)(added to warning label in September 2023)

Ozempic consumers have also reported obstructions and intestinal blockages that began after starting the medication for diabetes or weight loss . Potential signs and symptoms associated with intestinal blockages allegedly linked to Ozempic include:

  • Blood in the stool
  • Constipation
  • Dark color urine
  • Diarrhea
  • Difficulty having bowel movements
  • Lack of appetite
  • Lethargy
  • Malaise (a feeling of illness or discomfort)
  • Rapid heartbeat
  • Swelling
  • Vomiting

Intestinal blockages may initially manifest with mild symptoms. However, without treatment, blockages can quickly become serious medical events. Intestinal obstructions and blockages are considered medical emergencies that must be taken seriously. Failure to treat an intestinal blockage quickly enough could result in infection, intestinal perforation, or even death.

Muscle loss

Many consumers are unaware that taking Ozempic could lead to extreme muscle loss . This can occur when people lose weight quickly without maintaining exercise habits and a balanced diet. Also known as sarcopenia, severe muscle loss can lead to death . Some common symptoms of muscle loss could include:

  • Decrease in muscle mass
  • Difficulty performing daily activities
  • Falls
  • Loss of stamina
  • Poor balance
  • Trouble climbing stairs
  • Walking slowly

Sarcopenia can also lead to other severe side effects and conditions, including insulin resistance, reduced bone density and lowered metabolism.

Other potential off-label side effects of Ozempic

Consumers have reported many other label side effects after starting Ozempic or Wegovy, including:

  • Malnutrition: You can become malnourished when your body is deprived of nutrients, minerals and vitamins. Symptoms of malnutrition include skin pigmentation changes, soft bones, bleeding gums, pale skin, rashes, thinning hair, achy joints and easy bruising.
  • Blood clots and deep vein thrombosis: Blood clots are coagulated clumps of blood. A 2021 study reported that Ozempic use increased the risk of deep vein thrombosis, a condition caused by blood clotting deep in the body. DVT can be a very serious condition and can lead to pulmonary embolism.

Anyone taking Ozempic or any semaglutide drug should not hesitate to contact their physician if they experience new or worsening side effects. It may also be in your best interests to connect with an Ozempic lawyer to explore your legal options.

Unexpected Ozempic side effects lead to lawsuits

The side effects not included on the Ozempic warning label are alarming. Thousands of people have allegedly been harmed, and records indicate manufacturer Novo Nordisk knew about these risks.Ozempic’s predecessor, Saxenda, caused similar side effects and was approved in 2014.

As of March 2024, tens of thousands of reports of health problems after taking Ozempic have been filed with the FDA Adverse Event Reporting System . Some noteworthy lawsuits include the following people affected by Ozempic:

  • A 52-year-old woman taking weekly semaglutide injections experienced gastroparesis symptoms within one month of starting Ozempic.
  • A 57-year-old woman taking dulaglutide injections every week for over a year began experiencing nausea, vomiting and bloating associated with delayed gastric emptying within three months of starting the prescription medication. These side effects improved when the patient stopped taking the dulaglutide. 
  • A 39-year-old woman needed to be hospitalized with significant gastrointestinal issues that have continued to affect her life even after she stopped taking Ozempic.

Patients suffering extreme side effects associated with Ozempic use have said the symptoms made it difficult or impossible to complete daily tasks or live life as they did before beginning Ozempic.

Legal action against Novo Nordisk may offer justice and compensation for affected people. Compensation can help people cover financial losses, medical expenses and other relevant economic and non-economic damages.

There are several types of gallbladder disease. Common symptoms associated with gallbladder disease include yellowing of the skin (jaundice), abdominal pain, fever, nausea and vomiting. (Added to warning label in March 2022)
  • Hypoglycemia: This condition means your blood sugar levels are lower than the standard range. Symptoms might include irritability, shakiness, illness, nausea or hunger, rapid heartbeat, sweating, lightheadedness and headache. Worsening symptoms can include slurred speech, blurred vision and seizures.
