Is coffee allowed during pregnancy second trimester?
The current NHS guidelines recommend that you should have less than 200mg a day if you’re pregnant. This is about 2 cups of instant coffee. However, our Tommy’s research centres show that the risk goes up the more you have. So, it’s a good idea to reduce the amount you have as much as possible, to protect your baby. Compromised maternal caffeine metabolism, disrupted placenta development, and an abnormal uterine environment may affect fetal development as well as the offspring’s health (F1), which may also influence the primordial germ cells (PGCs) of the developing fetus and transfer diseases, such as cardiomyopathy, to the F2 .Findings from this large population-based prospective cohort study suggest that caffeine intake of ≥6 units/d during pregnancy is associated with impaired fetal length growth. Length- or skeletal-related fetal growth characteristics seemed to be consistently affected from the first trimester onward.The researchers noted that caffeine is believed to cause blood vessels in the uterus and placenta to constrict, which could reduce the blood supply to the fetus and inhibit growth.Consuming caffeine not only interferes with regular development (acquisition of skills, emotional and social health, and more), it also instigates side effects that may have long-term health consequences if a child also has underlying health conditions, such as high blood pressure, chronic kidney disease, or anxiety .
Is one coffee a day ok when pregnant?

Even small amounts of caffeine in so-called decaf products can add up if you’re having multiple servings.Conclusion. Drinking coffee during pregnancy is associated with an increased risk of stillbirth but not with infant death.While there are caffeine-free sodas, it’s also best to limit them, since many are high in calories, which can lead to unnecessary weight gain.

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. Remember that caffeine also is found in tea, chocolate, energy drinks, and soft drinks.Current guidelines from the American College of Obstetricians and Gynecologists (ACOG) and other experts say that it’s safe for pregnant women to consume up to 200 milligrams (mg) of caffeine a day (the equivalent of one 12-ounce cup of coffee).Caffeine crosses the placenta to your baby. Any amount of caffeine can also cause changes in your baby’s sleep pattern or normal movement pattern in the later stages of pregnancy. Remember, caffeine is a stimulant and can keep both you and your baby awake.According to a study published in Fertility and Sterility, women who consume 500 milligrams of caffeine daily (the equivalent of four to five cups of coffee) produce 70% more estrogen in the follicular phase of their menstrual cycle than women who consumed less than one cup of coffee per day.Moderate caffeine consumption (less than 200 mg per day) does not appear to be a major contributing factor in miscarriage or preterm birth.
What happens if you drink too much caffeine while pregnant?
In particular, high caffeine consumption while pregnant can cause increased fetal catecholamine levels, which could lead to increased fetal heart rate and placental vasoconstriction and impair fetal oxygenation. Therefore, caffeine intoxication in pregnant women should be treated immediately. Current studies show that maternal caffeine exposure not only severely disrupts embryo implantation but also disrupts ongoing midterm fetal growth and development, resulting in pregnancy loss, low birth weight, and impaired brain development in offspring on postnatal day 6 (P6) [35–38,55].Common side effects include subfertility, intrauterine growth retardation, low birth weight, and spontaneous abortion [13]. The process of caffeine absorption takes place at a rapid pace in the small intestine.Effects of too much caffeine. If you drink too much caffeine, you may find that your baby becomes unsettled, jittery and/or sleeps poorly. Too much caffeine is different for every mum and depends on various things such as how well your body processes caffeine.Though maternal caffeine and paraxanthine concentrations were generally not associated with risk of overweight or obesity, our findings indicate that maternal caffeine consumption is associated with long-term decreases in child height.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. As there can be many causes of miscarriage, it is hard to know if an exposure or other factors are the cause of a miscarriage.

Does caffeine cross the placenta?
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%. 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].Any amount of caffeine can also cause changes in your baby’s sleep pattern or normal movement pattern in the later stages of pregnancy. Remember, caffeine is a stimulant and can keep both you and your baby awake.Too much caffeine during pregnancy may increase your risk of complications including miscarriage, stillbirth and low birth weight.
