Pregnant women could benefit from simple, cheap, “self-help” remedies for mild nausea and vomiting. Ginger, vitamin B6 and possibly acupressure wrist-bands might relieve symptoms for some women, according to a recent overview of research in this area. The review has identified some promising areas for future research. For sickness that doesn’t respond to “self-help” remedies, prescribed medication like antihistamines or anti-sickness tablets may help. Hospital treatment, including combinations of drugs and intravenous fluids, may be indicated if this doesn’t work. The review assessed 73 studies that measured how well 33 types of treatment worked for pregnant women experiencing nausea and vomiting. Severity of symptoms could range from simple “morning sickness” to the more severe condition of hyperemesis gravidarum. The review gives some evidence on treating pregnant women, but it is limited, especially for more severe symptoms. The authors highlight the need for more robust research to compare treatments with costs and clarify the safety of some drugs.
