Acupuncture may reduce frequency of nausea and vomiting during pregnancy when combined with medicationAcupuncture may reduce nausea and vomiting during pregnancy

AI-generated summary of the cited source, checked by automated accuracy review. How we work

Key Takeaway
Note that acupuncture may reduce nausea frequency in pregnancy, but evidence quality is currently low.

This overview of systematic reviews synthesized data from 9 meta-analyses to evaluate the efficacy and safety of acupuncture for nausea and vomiting during pregnancy (NVP). The analysis focused on outcomes including frequency of symptoms, ketonuria-negative rates, and serum electrolyte balance.

Findings indicate that adding acupuncture to medication reduces the frequency of nausea and vomiting compared to medication alone. Additionally, patients receiving acupuncture plus medication showed accelerated ketonuria-negative rates and maintained stable serum electrolyte balances. However, these results are based on a body of evidence characterized by low reliability.

Several limitations impact the certainty of these findings, including methodological flaws in included studies, publication bias, inaccurate data, and a limited number of high-quality randomized controlled trials. GRADE assessments categorized 20 outcomes as low quality and 30 as very low quality.

Clinical practice relevance is constrained by the low quality of evidence. While acupuncture appears to alleviate NVP symptoms to some extent, its definitive efficacy and safety profile remain unclear due to significant study limitations.

Morning sickness can be a grueling part of pregnancy, making it hard for some women to keep down food or feel comfortable in their own skin. New research looked at whether acupuncture could help manage these symptoms when used alongside standard medications.

The analysis found that adding acupuncture to medication helped reduce how often nausea and vomiting occurred. It also showed faster rates of staying free from ketonuria, which is a condition where the body burns fat for energy because it lacks enough carbohydrates. Additionally, patients who received both treatments maintained their electrolyte balance.

While these results are encouraging, we have to look at the data carefully. The evidence is currently considered low quality due to flaws in the original studies and a lack of high-quality trials. Because of these limitations, doctors cannot yet say for certain how effective acupuncture is as a standard treatment.

What this means for you:
Acupuncture may reduce vomiting during pregnancy, but more high-quality research is needed to confirm its effectiveness.

Common questions

Can acupuncture help with morning sickness?

The research suggests that acupuncture can reduce the frequency of nausea and vomiting when used alongside medication. It also showed an improved rate for staying ketonuria-negative, which helps ensure the body is getting enough nutrients during pregnancy.

Is it safe to use acupuncture while pregnant?

The study did not report any specific adverse events or serious safety issues regarding acupuncture in pregnancy. However, because of low-quality data and methodological flaws in the source studies, its exact safety profile is not fully established.

How reliable are these findings for pregnant women?

The evidence is currently considered to have low reliability. Many of the included studies had significant flaws or inaccurate data, meaning while acupuncture shows promise in reducing symptoms, more high-quality trials are needed to confirm its effectiveness.

BackgroundNausea and vomiting during pregnancy (NVP) are common symptoms in early pregnancy. NVP can further affect the physical and mental health of pregnant women. Acupuncture has shown potential clinical value in treating NVP and can be considered a beneficial supplemental therapy for NVP. However, existing systematic reviews (SRs) and meta-analyses (MAs) on the efficacy and safety of acupuncture for NVP have yielded inconsistent conclusions, and their methodological and reporting quality has not yet been systematically and comprehensively evaluated.ObjectiveTo synthesize the existing evidence on the efficacy and safety of acupuncture for the treatment of NVP and to assess the quality and risk of bias of the available SRs/MAs.MethodsTwo researchers independently searched nine databases for relevant literature, screened studies according to predefined inclusion and exclusion criteria, and extracted data from the eligible SRs and MAs. The methodological quality, reporting completeness, risk of bias, and strength of evidence were rigorously evaluated using AMSTAR 2, PRISMA-A, ROBIS, and GRADE, respectively. In addition, the GROOVE tool was used to assess the degree of overlap among the original studies by calculating the corrected covered area (CCA).ResultsWe retrieved a total of 288 studies, and 9 SRs/MAs were ultimately included in this review. The methodological quality of one study was moderate, while two studies were rated as low and the remaining six as critically low. According to the PRISMA-A statement, the reporting items of the included SRs/MAs were relatively complete. Furthermore, it revealed a slight overlap among the original studies, with a CCA of 3.64%. The results based on GRADE showed that of the 52 outcomes, 2 were rated as moderate quality, 20 as low quality, and 30 as very low quality. Descriptive analysis showed that acupuncture combined with medication could reduce the frequency of nausea and vomiting, accelerate the ketonuria-negative rates, and maintain serum electrolyte balance. Acupuncture also appeared to reduce the frequency of nausea and vomiting compared with medication alone.ConclusionsAcupuncture appears to relieve the symptoms of NVP to a certain extent. However, the current evidence is limited by low reliability, methodological flaws, publication bias, and inaccurate data. Therefore, the true efficacy remains unclear. Although acupuncture shows preliminary clinical potential, high-quality randomized controlled trials with standardized outcome indicators are still needed to draw definite conclusions.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD420261326889.
