Important: Vomiting is a possible early side effect of Semaglutide, especially during dose escalation.

Why Does Semaglutide Cause Vomiting?

Semaglutide slows gastric emptying and changes appetite regulation in the brain, which can lead to nausea and vomiting in sensitive patients.

Key mechanisms:
  • Delayed stomach emptying
  • Strong satiety signaling
  • Gastrointestinal sensitivity during dose increase

How Long Does Vomiting Last?

  • Usually occurs during early treatment phase
  • More common after dose increases
  • Often improves within days to weeks
  • Less common once stable dose is reached

How to Manage Vomiting

Recommended strategies:
  • Eat small, frequent meals
  • Avoid fatty or heavy foods
  • Stay hydrated with small sips of water
  • Avoid lying down immediately after eating
  • Do not skip dose changes without medical advice

When Vomiting Becomes Concerning

  • Persistent vomiting preventing hydration
  • Signs of dehydration (dizziness, dry mouth)
  • Severe abdominal pain
  • Rapid or excessive weight loss
