Miscarriage risk increases each week alcohol is used in early pregnancy
Impact of alcohol use rises through the ninth week of pregnancy, and risk accrues regardless of whether a woman reported having fewer than one drink or more than four drinks each week. Risk is also independent of the type of alcohol consumed and whether the woman had episodes of binge drinking.
Biologically, little is known about how alcohol causes harm during early pregnancy, but it may increase miscarriage risk by modifying hormone patterns, altering the quality of implantation, increasing oxidative stress or impairing key pathways.
To avoid increased risk of miscarriage, the researchers emphasize the importance of using home pregnancy tests, which can reliably detect pregnancy before a missed period, and ceasing alcohol use when planning a pregnancy or when pregnancy is possible.
