Should I start a GLP-1 if I am already constipated?
No. Fix the plumbing first.
No. Adding a slow-down drug to an already backed-up system is a recipe for disaster.
Your gut health is the foundation for everything else here. If you are not pooping regularly, do not start this medication yet.
Stock up on soluble fiber, find a probiotic you like, and start drinking more water today. The target is comfortable every day, or at minimum every third day. We want a slow flow, not a no flow.
None of this is medical advice. It is educational material drawn from FAT BITCH: Killing the Willpower Myth by Cat Clark, and it does not replace your prescriber, your pharmacist, or your actual doctor. If something here does not match what your care team told you, go with your care team and bring this along to the conversation.
