Too Much Caffeine May Increase Miscarriage Risk
Too much caffeine during pregnancy may increase the risk of miscarriage, a new study says, and the authors suggest that pregnant women may want to reduce their intake or cut it out entirely.
Many obstetricians already advise women to limit caffeine, though the subject has long been contentious, with conflicting studies, fuzzy data and various recommendations given over the years.
The new study, being published Monday in the Journal of Obstetrics and Gynecology, finds that pregnant women who consume 200 milligrams or more of caffeine a day -- the amount in 10 ounces of coffee or 25 ounces of tea -- may double their risk of miscarriage.
Pregnant women should try to give up caffeine for at least the first three or four months, said the lead author of the study, Dr. De-Kun Li, a reproductive and perinatal epidemiologist at the Kaiser Permanente Division of Research in Oakland, Calif.
