Does Ozempic List Constipation as a Side Effect?
Ozempic (semaglutide) commonly causes gastrointestinal issues, including constipation, due to its mechanism of slowing gastric emptying to regulate blood sugar. Clinical trials reported constipation in 3-5% of patients, typically mild to moderate.[1][2]
How Severe Can Constipation Get with Ozempic?
Most cases resolve with hydration, fiber, or laxatives, but severe constipation occurs in rare instances, sometimes linked to ileus (intestinal blockage). Post-marketing reports include cases of severe GI obstruction or bowel issues requiring medical attention.[3][4] Patient forums and FDA adverse event data note instances where symptoms like persistent bloating, pain, and no bowel movements for days led to ER visits.[5]
Are There Hospitalization Cases from Ozempic Constipation?
Yes, severe constipation has led to hospitalizations, though it's uncommon. FDA's FAERS database logs reports of semaglutide-related bowel obstruction or severe constipation necessitating inpatient care, often in patients with predisposing factors like prior GI surgery or dehydration.[5][6] A 2023 study in JAMA analyzed GLP-1 agonists like Ozempic and found elevated risks for gastroparesis and bowel obstruction, with some hospitalizations (odds ratio 4.22 for obstruction).[7] No direct causation is proven in all cases, but these events prompted label updates warning of ileus risk.[3]
What Increases Risk of Severe Constipation?
Dehydration, low-fiber diet, inactivity, or combining with other constipating drugs (e.g., opioids) heighten severity. Patients over 65 or with conditions like hypothyroidism face higher odds. Starting at higher doses without titration also contributes.[2][4]
What Do Doctors Recommend if Constipation Worsens?
Seek immediate care for no bowel movements over 3 days, severe pain, vomiting, or distended abdomen—these signal potential obstruction needing hospitalization. Management includes osmotic laxatives (e.g., MiraLAX), stool softeners, or dose adjustment; discontinuation if persistent.[1][8]
How Does Ozempic Constipation Compare to Other GLP-1 Drugs?
Similar profile to Wegovy (same drug) or Mounjaro (tirzepatide), but Ozempic users report slightly higher constipation rates in head-to-head data (5% vs. 3% for tirzepatide). All carry ileus warnings.[7][9]
