Side effects are a leading reason people stop GLP-1 medications too early. Logging them well helps you and your prescriber make informed decisions.
What to log
Record nausea, vomiting, reflux, constipation, fatigue, and appetite changes — each tied to your current dose and the date.
Spotting patterns
A timeline reveals whether symptoms are improving with adaptation or worsening, which is far more useful than memory alone.
When to contact your prescriber
Severe, persistent, or worsening symptoms warrant a conversation with your prescriber. Always seek medical advice for anything that concerns you.
