Ozempic is a type of prescription drug in the category of glucagon-like peptide-1 (GLP-1) agonists used to treat type 2 diabetes. Additionally, it has become popular for its off-label use for weight loss.

Additional research into its uses, effectiveness, and side effects is ongoing.

If you’re also being treated for inflammatory bowel disease (IBD), which includes ulcerative colitis (UC), you might be wondering whether Ozempic is safe for you.

There are several connections between type 2 diabetes (T2D), obesity, and UC. People with type 2 diabetes are at an increased risk of developing UC.

So far, the evidence suggests that it’s safe for people with UC to take Ozempic and other similar medications.

Gastrointestinal side effects of Ozempic and other medications with the active ingredient semaglutide include:

  • abdominal pain
  • diarrhea
  • nausea and vomiting
  • constipation
  • heartburn
  • increased gas (released via flatulence or burping)

GLP-1 agonists have also been identified as increasing the risk for bowel obstruction, pancreatitis, and gastroparesis.

Other side effects have been identified, some of which can be serious.

There’s currently no research suggesting that taking Ozempic or other semaglutides can worsen existing symptoms of UC.

However, it can cause several gastrointestinal symptoms that are also seen in UC, such as:

  • constipation or diarrhea
  • abdominal pain
  • constipation

In fact, there’s some evidence that it can improve symptoms of UC. This is because people with UC who are overweight may experience more severe symptoms. Theoretically, losing weight if you’re overweight may improve UC symptoms.

According to the researchers of a 2021 study involving 3,751 participants with type 2 diabetes, those with T2D and IBD who took GLP-1 medications were noted to have fewer IBD symptoms and complications than those who received other treatments.

While further research is needed, there is also some evidence that medications like Ozempic may have anti-inflammatory properties that could decrease the symptoms or side effects of IBD and other conditions, according to a 2024 study.

No current evidence asserts that taking Ozempic is unsafe for people with UC. However, research on the drug is ongoing.

If you’re interested in taking Ozempic and have UC, ask your doctor whether it’s safe for you.
