From the Guidelines

Yes, Ozempic (semaglutide) can cause diarrhea as a common side effect. According to the most recent study from 2023 1, diarrhea is listed as one of the common side effects of semaglutide, along with nausea, vomiting, and constipation. The study highlights the importance of titrating the dose every 4 weeks as tolerated by the patient to minimize side effects.

Some key points to consider when taking Ozempic and experiencing diarrhea include:

  • Staying well-hydrated to prevent dehydration
  • Eating smaller, more frequent meals
  • Avoiding high-fat foods
  • Limiting caffeine and alcohol consumption
  • Contacting your healthcare provider if diarrhea is severe, persistent, or accompanied by signs of dehydration

The mechanism of action of Ozempic as a GLP-1 receptor agonist can alter digestive processes, leading to diarrhea in some patients 1.

If you experience diarrhea while taking Ozempic, it is crucial to discuss your symptoms with your healthcare provider to determine the best course of action.

From the Research

Ozempic and Diarrhea

  • Ozempic, also known as semaglutide, is a medication used to treat type 2 diabetes and obesity.
  • The provided studies do not directly address the relationship between Ozempic and diarrhea.
  • However, studies on drug-induced diarrhea suggest that many drugs can cause diarrhea by disrupting mechanisms controlling mucosal permeability, transport, motility, and gut metabolism 4.
  • Treatment for drug-induced diarrhea may include withdrawal of the offending drug or use of nonspecific agents such as loperamide 4.

Loperamide and Diarrhea

  • Loperamide is an effective and safe antidiarrheal agent that has been used to treat chronic diarrhea 5, 6, 7.
  • Studies have shown that loperamide can reduce stool frequency, improve stool consistency, and relieve urgency and incontinence in patients with chronic diarrhea 5, 6, 7.
  • However, the use of loperamide is not recommended in the treatment of infants and young children with acute diarrhea due to potential side effects 8.

Conclusion Not Available

No direct evidence is available to confirm whether Ozempic causes diarrhea. However, it is known that some medications can cause diarrhea as a side effect 4.
