Important: Diarrhea is a common gastrointestinal side effect during early Semaglutide treatment or dose increases.

Why Does Semaglutide Cause Diarrhea?

Semaglutide affects gastrointestinal motility and slows digestion, which can disrupt normal bowel patterns in some patients.

Main mechanisms:
  • Changes in gut motility
  • Altered digestion speed
  • Dietary sensitivity during treatment

How Long Does Diarrhea Last?

  • Most common during first 2–6 weeks
  • May reappear after dose increases
  • Usually improves as body adapts
  • Becomes less frequent at stable dose

How to Manage Diarrhea

Practical strategies:
  • Stay hydrated (water + electrolytes)
  • Avoid fatty and spicy foods
  • Eat low-fiber, bland meals temporarily
  • Do not overeat during dose escalation
  • Monitor symptoms during titration phases

When to Seek Medical Help

  • Severe or persistent diarrhea
  • Signs of dehydration
  • Blood in stool
  • Severe abdominal pain
  • Rapid weight loss or weakness
