Could this pattern fit CHS?

Tap through one question at a time and leave with a practical next step. This tool cannot diagnose CHS, and your answers never leave this browser.

Cannabis exposureHave you used cannabis regularly for months or years?

This establishes context; it does not diagnose CHS.

Episode patternDo nausea or vomiting episodes return in cycles?

Think about distinct episodes separated by periods of improvement.

Between episodesDo you notice morning nausea or stomach discomfort between intense episodes?

Some people report an earlier, less intense phase before recurrent vomiting begins.

Heat behaviorDo hot showers or baths temporarily reduce discomfort?

This is a reported clue, but it is not required and is not diagnostic by itself.

Cannabis pauseDid symptoms improve during a sustained period without cannabis?

If you have not stopped long enough to compare, choose “No or not tried.”

RecurrenceHave symptoms returned after resuming cannabis?

If you have never stopped or are unsure, choose “No or unsure.”

Safety checkAre you unable to keep fluids down or showing severe dehydration signs?

Fainting, confusion, very little urine, or severe weakness requires urgent care.
