Pregnant women should consider avoiding caffeine, say researchers who found even moderate consumption in early pregnancy raises the miscarriage risk.
According to BBC News Online, the U.K.’s Food Standards Agency currently sets an upper limit during pregnancy of 300 mg, or four cups of coffee per day.
But an American Journal Of Obstetrics And Gynaecology study found more than 200 mg of caffeine per day doubled the risk compared to abstainers.
Experts said they would review the data to see if advice needed changing. Pat O’Brien, consultant obstetrician and spokesman for the Royal College Of Obstetricians And Gynaecologists, said based on the findings he would now be advising women in their first 12 weeks of pregnancy to abstain from caffeine altogether.
“The first 12 weeks is a very vulnerable time for the baby. It’s when most miscarriages occur,” he explained.
There are a number of well-established risk factors, such as increased maternal age, a previous history of miscarriage, and infertility.
But the causes of the majority of miscarriages are not fully understood.
