[Leg cramps in pregnancy--how common are they?].

Leg cramps in pregnancy, defined as painful spasms of the calf, were investigated among women giving birth at the maternity ward at Baerum Hospital from 1 October to 20 October 1997. A questionnaire distributed to 120 women three days after parturition revealed that 45% had suffered from leg cramps during pregnancy. Among 54% of them the cramps appeared after the 25th week of pregnancy. 76% of the women had experienced the symptoms twice per week or less often; 81% of them suffered from painful cramps only during night-time. We conclude that leg cramps are still a common symptom in pregnancy and may compromize sleep and hence the ability to work.
