Common questions

What causes constipation on GLP-1 medications?

GLP-1 receptor agonists slow stomach emptying and act on appetite centers in the brain. That mechanism is part of why they work, and it's also behind most of the day-to-day side effects people notice. What you eat can dial the effect up or down.

Which foods tend to help with constipation?

In general, smaller meals, enough protein, steady fluids, and foods that aren't overly greasy, sugary, or heavy tend to sit better. The leaf pages below get specific.

When should I call my prescriber about constipation?

If symptoms are severe, persistent, stop you from staying hydrated, or come with pain, vomiting, or other warning signs, contact your prescriber or seek care. Don't change your medication dose on your own.
