2-cup coffee habit may double miscarriage risk

Drinking a couple of cups of coffee a day has long been considered safe during pregnancy, but a new study finds that even this modest amount of caffeine could double a womanÂ’s risk of miscarriage.

Doctors are split on what this means for pregnant women, with some advising avoiding caffeine altogether and others saying buzz-inducing beverages are still safe in moderation.

Previous studies have linked caffeine to an increased risk of miscarriage, but they have focused on higher doses and the connection has been controversial, with some experts arguing that the research didn't account for morning sickness. The nausea and vomiting of morning sickness, caused by elevated hormones, is generally a sign of a reduced risk of miscarriage — and also can lead women to stop drinking their usual coffee or other caffeinated drinks. The concern was that the cutback in caffeine among these women could make it appear caffeine was associated with miscarriage
