Treatments for morning sickness, the nausea and vomiting experienced by up to 80 percent of pregnant women, are plentiful, from using acupuncture or eating ginger to taking vitamin B6.
But the evidence that any of these treatments work is limited, according to a new review.
”There’s no strong evidence about any treatment for morning sickness,” researcher Anne Matthews, RN, PHD, a registered midwife at Dublin City University in Dublin, Ireland, told WebMD.
She and her colleagues looked at the results of 27 trials involving 4,041 women taking a range of treatments.
The bright spot about morning sickness?
“It usually improves over time,” Matthews said.
The review was published in the Cochrane Database of Systematic Reviews. The Cochrane Reviews bring together research on health care and are viewed as the ”gold standard” for determining how effective different treatments are.
But Matthews and other doctors who reviewed the study said it can’t hurt to try treatments that are safe, and that they may help some women.
Morning sickness is a misnomer, Matthews said, as it can occur any time of the day or night. It typically occurs mainly in the first trimester, from the 6th to the 12th week of pregnancy, but can last longer.
