Unusual Case of Cannabinoid Hyperemesis with Bradycardia and Cold-Water Relief
A case report described a non-classical presentation of cannabinoid hyperemesis syndrome featuring bradycardia and symptom relief from cold (not hot) water, expanding the known clinical picture.
Quick Facts
What This Study Found
This case report described a patient with cannabinoid hyperemesis syndrome who presented with atypical features. Unlike the classic presentation where hot water relieves symptoms, this patient found relief from cold temperatures.
The patient also developed bradycardia (slow heart rate), which is not part of the classical CHS description. The authors emphasized that non-classical forms of CHS exist and that clinicians should maintain a broad differential when evaluating chronic cannabis users with cyclic vomiting.
Key Numbers
Single case; atypical features: bradycardia, cold-water relief (vs. typical hot-water relief)
How They Did This
Single case report documenting an atypical presentation of cannabinoid hyperemesis syndrome with bradycardia and cold-temperature relief.
Why This Research Matters
Expanding the recognized presentation of CHS beyond the classic triad (cyclic vomiting, chronic cannabis use, hot water relief) could prevent missed diagnoses when patients present with non-classical features.
The Bigger Picture
As CHS becomes more widely recognized, clinical variants are being documented. These non-classical presentations challenge the existing diagnostic criteria and suggest the underlying pathophysiology may be more complex than initially understood.
What This Study Doesn't Tell Us
Single case report represents the lowest level of clinical evidence. Cannot determine how common non-classical presentations are. Bradycardia could have had other causes.
Questions This Raises
- ?How common are non-classical CHS presentations?
- ?Does the response to cold versus hot water indicate different pathophysiological mechanisms?
- ?Should diagnostic criteria for CHS be broadened?

Evidence Hierarchy
Describes what happened to one person or a small group.
What do these levels mean? →Frequently Asked Questions
Is it always hot showers that help with CHS?
Not always. This case report documented a patient whose symptoms were relieved by cold temperatures instead. This suggests that the thermoregulatory mechanism underlying CHS may be more variable than initially thought.
Can CHS affect your heart rate?
This case included bradycardia (slow heart rate). While not part of the classical CHS description, it suggests that the autonomic nervous system disruption in CHS may extend beyond the gastrointestinal system.
