See when a symptom usually peaks and fades

Opens the full symptom index with the intensity timeline — pick a symptom and see the typical peak-and-fade pattern reported by GLP-1 users.

What the result means

The timeline is a directional pattern, not a personal prediction. It helps you tell whether what you're feeling is on the expected curve or is something that has been going on longer than usual.

Limitations

The intensity curves are educational patterns. They cannot predict what you personally will experience, and they do not replace a call to your prescriber if a symptom is severe or getting worse.
