One of the first things you want when you get out of bed is coffee. But on a hot summer day, you might want to gulp down an entire bottle of cola. Others may settle for an energy drink or a cup of tea. Regardless of what you drink, what your body craves for is a dose of caffeine, which affects people in different ways.

The craving doesn’t go, and you’d want that cup of coffee or tea, or cola anyway. But what about consuming caffeine during pregnancy? How much coffee or tea should you have? Or should you skip it altogether?

Here, MomJunction tells you all about caffeine and whether or not it is good for you when pregnant.

How Much Caffeine Can A Pregnant Woman Have In A Day?

Pregnant women can consume up to 200mg of caffeine a day, which is less than a full cup of coffee (1). In other words, you can take one-and-a-half mugs of filtered coffee or two mugs of instant coffee every day to satiate the caffeine cravings (2).

Though it is best to stay away from caffeine in pregnancy, experts suggest that it is okay even if you drink as long as it is within the limit.

What Happens When You Drink Too Much Of Caffeine When Pregnant?

Your body can tolerate small to moderate amount of caffeine every day. Excess consumption, however, can have adverse side effects for you and the baby.

Effects of caffeine on pregnant women:

  • Caffeine is a stimulant, and too much of it can increase the blood pressure and heart rate, causing anxiety, insomnia and sleep problems (3).
  • It is a diuretic that increases your frequency of urination, and removes water from the body, making you dehydrated (4).
  • Regular consumption of caffeine can make you addicted to it (5). When you stop it abruptly, you are most likely to experience withdrawal symptoms such as irritability, fatigue, and headache.

Effects of caffeine on the fetus:

Caffeine can also cross the placenta and affect the developing organs in the fetus, which cannot handle the caffeine. Also, caffeine:

  • Stimulates the baby, keeping it active for a long time.
  • Stimulates the heart rate of the fetus, which could lead to sleep disturbances, and irregular heartbeat (6).

Continuous intake of excess caffeine can build up caffeine reserves in the fetal body, and after birth, the baby may show withdrawal symptoms such as vomiting, jitteriness, and irritability (7).

Effects of caffeine on pregnancy:

Caffeine could also lead to the following pregnancy complications:

  1. Birth defects: Although excess intake of caffeine can create irregular heartbeat, there is no scientific evidence saying it could lead to disability or deformity (8).
  1. Miscarriage: Some studies have concluded that there is a link between caffeine and miscarriage or early stillbirth. In one analysis of 26 studies, the findings showed that caffeine would increase the risk of pregnancy loss (9). Another study concludes that the chance of miscarriage is greater when pregnant women consume over 200mg of caffeine every day (10). In a different study, findings say that caffeine can only increase the risk of miscarriage when combined with smoking, alcohol, and drugs (11).
  1. Preterm labor: Though some people believe that caffeine can increase the possibilities of premature labor, studies find no association between caffeine and preterm delivery (12).
  1. Low birth weight babies: Caffeine intake of more than the recommended amount can lead to fetal growth restriction and low birth weight in babies (13).

Medications also contain caffeine!

Some pain-relieving medications, especially those meant for cold and flu, contain caffeine to counter their sedative effects (15). Learn to read the composition of medications before you take them, and try to avoid over-the-counter medications. Always seek your practitioner’s approval before taking any medicines.

Are There Any Safe Alternatives To Coffee During Pregnancy?

Moderate consumption will not do any harm. But if you want to reduce your consumption or give up coffee, there are other safer, less-caffeinated alternatives you can choose from.

  1. Green tea: Green or herbal teas are low in caffeine. They are barely brewed and are your safest bet.
  1. Instant coffee: Choose instant coffee rather than filter coffee. Half a teaspoon of coffee with milk will be a better option than filtered coffee.
  1. Decaf: The caffeine content is markedly reduced in decaf coffee. You can safely opt for this when you are pregnant.

You can also try the following caffeine-free alternatives. But if you are not able to avoid caffeine completely, take them just before your regular coffee or tea time. This helps curb the caffeine habit.

7. Is it okay to drink coffee in the third trimester?

It is okay to drink coffee in the third trimester unless you consume beyond the recommended limit. Excessive intake is likely to increase the chances of growth retardation in the fetus (17).

If you are not a habitual coffee or tea drinker, try to avoid them completely. But if coffee is your go-to beverage in the morning, noon and night, you may have to cut down the intake. Try to enjoy your favorite brews in moderation to avoid any side-effects and to promote healthy growth of the fetus.
