Another Case of Cannabinoid Hyperemesis Syndrome Mistaken for Hyperemesis Gravidarum
A pregnant woman with chronic marijuana use had severe nausea and vomiting diagnosed as CHS after initial evaluation for hyperemesis gravidarum, reinforcing the importance of marijuana history in pregnancy nausea.
Quick Facts
What This Study Found
This case report documents a pregnant woman with chronic marijuana use who presented with severe nausea, vomiting, and compulsive bathing, meeting criteria for cannabinoid hyperemesis syndrome. The presentation was initially evaluated as hyperemesis gravidarum due to the shared symptoms.
The authors emphasize that with marijuana legalization increasing, CHS incidence among pregnant women may rise. Recognition of CHS in this population is important because it avoids extensive unnecessary workups, reduces healthcare costs, and directs treatment toward the effective intervention: marijuana cessation.
The case illustrates the value of obtaining a complete substance use history, including marijuana, in all pregnant patients presenting with severe nausea and vomiting.
Key Numbers
Single case report. Chronic marijuana use history. Nausea, vomiting, compulsive bathing during pregnancy. Diagnosis: CHS.
How They Did This
Single case report with clinical description and literature review of CHS in pregnancy.
Why This Research Matters
This is another case demonstrating the diagnostic overlap between CHS and hyperemesis gravidarum. As marijuana becomes more socially acceptable, healthcare providers need to routinely screen for cannabis use in pregnant patients with severe nausea.
The Bigger Picture
The accumulation of CHS case reports in pregnant women is building the case for routine cannabis screening as part of the hyperemesis gravidarum workup. This relatively simple addition to clinical practice could prevent unnecessary invasive testing and hospitalizations.
What This Study Doesn't Tell Us
Single case report. Limited clinical detail in the abstract. Cannot establish how common CHS misdiagnosis is in pregnancy.
Questions This Raises
- ?Should cannabis screening be standard in the hyperemesis gravidarum workup?
- ?Does CHS during pregnancy carry additional risks compared to non-pregnant CHS?
- ?How quickly do CHS symptoms resolve with cannabis cessation during pregnancy?
Trust & Context
- Key Stat:
- CHS and hyperemesis gravidarum share nearly identical presentations in pregnancy
- Evidence Grade:
- Single case report reinforcing a known diagnostic pitfall.
- Study Age:
- Published in 2015. Multiple similar case reports have since further established CHS as a differential for pregnancy vomiting.

What do these levels mean? →Frequently Asked Questions
How common is CHS in pregnant women?
The exact prevalence is unknown. With 2-5% of pregnant women reporting marijuana use and CHS developing in a subset of chronic users, the condition is likely underdiagnosed in pregnancy settings.
Does stopping marijuana immediately resolve CHS in pregnancy?
CHS symptoms typically improve within days to weeks of stopping marijuana. In pregnancy, early cessation is especially important to prevent dehydration and nutritional complications that could affect fetal development.
