Sorry mum, there's no morning sickness cure

No reliable treatments exist for curing morning sickness, experts said today.

A range of medicines and remedies such as acupuncture, B vitamins and ginger appear to have little or no effect, a review of existing studies found.

In fact, some treatments lead to side-effects. For example, ginger can cause heartburn among some women.

Between 70pc and 85pc of women will experience nausea during pregnancy, with about half suffering vomiting. For the latest study, researchers looked at 27 trials on more than 4,000 women up to the 20th week of pregnancy.

They found the data in many of the trials was limited and some results were inconsistent, meaning it was difficult to draw solid conclusions.



STIMULATION



Women concerned about the effect of drugs on their unborn child have increasingly been turning to alternative treatments, the experts said.

However, they argued there is scant evidence these therapies worked and they tend to be less well regulated than pharmacological interventions.

Six studies on the role of acupressure and two on acupuncture resulted in no significant benefits for the women treated, the review found. However, one study of acu-stimulation (where acupuncture points are subjected to mild electrical stimulation) led to some improvement over three weeks.

The experts found limited evidence of ginger relieving nausea or sickness, and very limited evidence for vitamin B6, antihistamines and antiemetic (anti-vomiting) drugs.

Dr Anne Matthews, of the school of nursing at Dublin City University, said: "A number of the studies we looked at appeared to show benefits, but in general the results were inconsistent and it was difficult to draw firm conclusions about any one treatment in particular."
