What This Study Found

A 34-year-old woman at 11 weeks gestation with intractable abdominal pain and nausea unresponsive to extensive gastrointestinal workup and multimodal antiemetic treatment was ultimately diagnosed with CHS. Topical capsaicin cream provided significant symptom improvement when oral pain management options were limited by pregnancy.

Key Numbers

Patient was 34 years old at 11 weeks gestation. Symptoms were refractory to multimodal antiemetic treatment before capsaicin was trialed.

How They Did This

Single case report from a clinical setting.

Why This Research Matters

CHS diagnosis is particularly challenging in pregnancy because nausea is expected, and treatment options are limited by fetal safety concerns. Topical capsaicin avoids systemic drug exposure, making it an attractive option.

The Bigger Picture

CHS is likely underdiagnosed in pregnant patients because symptoms overlap with hyperemesis gravidarum. As cannabis use during pregnancy remains common despite medical advice against it, clinicians need to consider CHS in the differential.

What This Study Doesn't Tell Us

Single case report provides the lowest level of clinical evidence. Cannot rule out spontaneous improvement or placebo effect. No long-term follow-up on pregnancy outcomes reported.

Questions This Raises

  • ?How often is CHS misdiagnosed as hyperemesis gravidarum?
  • ?Is topical capsaicin safe throughout pregnancy for CHS management?
