Is acupuncture for morning sickness safe during pregnancy?

What does the evidence say about acupuncture for morning sickness during pregnancy?

1. A 2024 systematic review and meta-analysis of 21 randomized controlled trials covering 2,392 pregnant women found acupuncture and moxibustion reduced ineffective cases compared with controls (RR 0.28, 95 percent CI 0.21 to 0.37), with no significant difference between acupuncture and sham acupuncture. 1
2. Safety in the same meta-analysis was reassuring on the serious end and less so on the minor end: there were no significant differences in severe adverse events between acupuncture and control, while needling-related events such as itching, bruising and pain were more frequent with real than sham acupuncture (RR 15.47, 95 percent CI 5.30 to 45.16). 1
3. A 2016 systematic review of Western and Chinese literature reported acupuncture roughly twice as effective as control (RR 2.09, 95 percent CI 1.42 to 3.06) and acupressure at PC6 a 41 percent symptom reduction against sham (RR 1.41, 95 percent CI 1.06 to 1.87), while continuous outcome measures such as the Rhodes Index and visual analogue scales showed no evidence of symptom relief. 2
4. Acupuncture is competing against a symptom that usually resolves on its own: about 8 out of 10 pregnant people have nausea and vomiting, it peaks between 7 and 12 weeks, and most find relief between 12 and 16 weeks, which is roughly the length of a full course of sessions. 3
5. NCCIH notes that relatively few complications from acupuncture have been reported, but that when it is not delivered properly it can cause serious adverse effects including infections, punctured organs and injury to the central nervous system. 4

Is acupuncture for morning sickness safe in each trimester?

• First trimester. The window where the trials sit and where nausea peaks, between 7 and 12 weeks. Acupuncture sessions in the reviewed studies typically ran 15 to 20 minutes, once or twice daily, over 4 to 10 days, which is a bigger commitment than most people expect.
• Second trimester. If symptoms persist here, the wristband version of the same idea is easier to sustain. Acupressure at PC6 showed a 41 percent symptom reduction against sham, using finger pressure or wristbands applied continuously for 4 to 14 days.
• Third trimester. Rarely the right tool this late, and persistent third-trimester nausea deserves a look for other causes. If you do continue, the safety caveat stands: acupuncture delivered improperly can cause serious adverse effects, so practitioner training matters more than technique.
