Frequently Asked Questions
Why do GLP-1 medications cause constipation?
GLP-1 medications slow down gastric emptying (how fast food moves through your digestive system). This is part of how they help you feel full longer, but it can also lead to constipation.
What is the best over-the-counter remedy for GLP-1 constipation?
Fiber supplements like psyllium husk or methylcellulose are often recommended. Stool softeners like docusate sodium can also help. Always check with your doctor.
