How does caffeine affect the fetus in the second trimester?
It increases fetal breathing and heart rates but can lead to reduced growth and a lower birth weight. Although it does not affect gestational length or cause hypertension, caffeine increases uterine contractions, potentially resulting in spontaneous abortion. A) In humans, caffeine intake during pregnancy may give rise to pregnancy complications, such as miscarriage [4,17], fetal growth restriction [5,12], and low birth weight [21–24], which would also increase the risk of overweight and impaired cognitive development in childhood [25–27].Caffeine passes the placental barrier freely; the fetus does not express the main enzymes that inactivate it [4,5], and caffeine metabolites have been found to accumulate in the fetal brain [6,7]. In 2005, a Scandinavian expert committee concluded that high caffeine intake may harm the fetus [5].Of the 1,063 pregnant women interviewed, 172 experienced a miscarriage during their pregnancies. The investigators found an increased risk of miscarriage with higher levels of caffeine consumption, with an adjusted hazard ratio of 2. CI] 1.Caffeine is rapidly absorbed and crosses the placenta freely. After ingestion of 200 mg caffeine, intervillous blood flow in the placenta was found to be reduced by 25%.
Can coffee affect my baby in the first trimester?
They found that women who drink even a moderate amount of coffee and soda a day during early pregnancy have a slightly higher risk of miscarriage, but that caffeine consumption prior to conception does not appear to elevate risk. Research suggests that moderate caffeine consumption (less than 200 milligrams per day) does not cause miscarriage or preterm birth. That’s the amount in one 12-ounce cup of coffee.Moreover, in pregnancy, caffeine reaches the fetus through the placenta (9). Therefore, high caffeine consumption while pregnant can increase fetal catecholamine levels, which can result in increased fetal heart rate and placental vasoconstriction, leading to impairment of fetal oxygenation (11).Caffeine can also over-stimulate the production of stomach acid, which can cause cramps and pains or diarrhoea.

Not all babies exposed to caffeine will have these symptoms. Of the 1,063 pregnant women interviewed, 172 experienced a miscarriage during their pregnancies. The investigators found an increased risk of miscarriage with higher levels of caffeine consumption, with an adjusted hazard ratio of 2. CI] 1.Furthermore, caffeine metabolites such as theophylline and paraxanthine can easily cross the placenta into the fetus, and because the caffeine metabolizing enzymes are underdeveloped in the fetus, the accumulation of caffeine and its metabolites can impact brain development in the fetus.Researchers have not reported an association between low (under 200 mg) levels of caffeine and an increased chance of miscarriage. Some studies suggest that the chance of miscarriage might be increased when people consume moderate (200-300 mg) or high (more than 300 mg) levels of caffeine.
