What helps, step by step
- Drink water throughout the day to keep your stools soft.
- Take a brief walk. Moving around helps your gut move.
- Place your feet on a small stool while you sit on the toilet.
- Ask about a stool softener or laxative from a drugstore.
- Eat smaller meals and stop when you feel full. These medicines cause the stomach to empty more slowly.
- Eat slowly. Your brain needs time to recognize when you feel full.
- Tell your prescriber if it does not ease. They might reduce the pace of dose increases or suggest another GLP-1.
Before taking anything from the drugstore, check it with the GLP-1 interaction tool.
