Constipation on GLP-1s: Prevention and Solutions

The other common GI issue - let’s address constipation directly.

Why It Happens

GLP-1 medications slow your entire GI system, not just your stomach. This means:

  • Slower transit time
  • More water absorption
  • Reduced appetite (less fiber intake)
  • Less overall food volume

Prevention is Key

Stay Hydrated

  • Minimum 64oz water daily
  • More if active or in heat
  • Spread throughout day
  • Caffeine doesn’t count

Fiber Intake

Even with reduced appetite, prioritize fiber:

  • Vegetables with every meal
  • Fruits (especially berries)
  • Whole grains when eating carbs
  • Consider supplement if needed

Movement

Activity helps gut motility:

  • Daily walking
  • Any movement helps
  • Don’t become sedentary
  • Even 10 minutes helps

Timing

  • Try to maintain regular bathroom schedule
  • Don’t ignore urges
  • Morning routine can help

When Prevention Isn’t Enough

Gentle Options First

  • Increase water significantly
  • Add magnesium (helps many people)
  • Prunes or prune juice
  • Chia seeds in water

OTC Solutions

  • Miralax (polyethylene glycol)
  • Fiber supplements (Metamucil, Benefiber)
  • Docusate sodium (stool softener)
  • Senna (stimulant - use sparingly)

What to Avoid

  • Don’t rely on stimulant laxatives regularly
  • Don’t ignore the problem for weeks
  • Don’t assume it will just resolve

When to See Provider

  • No bowel movement for 5+ days
  • Severe abdominal pain
  • Blood in stool
  • Persistent issue despite interventions
