Birth defects were associated with caffeine consumption in some animal studies. However, they’re inconclusive in humans.

Some animal studies concluded that mothers who consumed caffeine had an increased risk of giving birth to offspring with birth defects. However, human studies haven’t yielded conclusive data.

A 2011 study analyzed the association of caffeine consumption during pregnancy with birth defects such as esophageal and intestinal atresia, microtia/anotia, craniosynostosis, diaphragmatic hernia, omphalocele, and gastroschisis.

Although they detected small risk increases in women who consumed caffeine during pregnancy, they didn’t find any convincing evidence. Thus, further research into the association of caffeine with birth defects is necessary.

2. If you drink caffeine during pregnancy, your baby may have a low birth weight

In 2014, researchers analyzed 13 existing studies in depth to determine if there’s a relationship between caffeine consumption during pregnancy and low birth weight (less than 5.5 pounds).

The result showed that high caffeine consumption was associated with an increased risk of low birth weight. For this reason, they recommend minimizing caffeine intake.

3. Caffeine may cause miscarriages

Excessive caffeine consumption is associated with an increased risk of miscarriage.

Researchers analyzed 28 studies to determine if there’s an association between caffeine consumption and miscarriage. The results suggested a relationship between both factors. Thus, for each 150 mg increase in caffeine intake, the risk of miscarriage increased by 19%.

4. Caffeine passes through the placenta and could affect the baby

Different studies support this myth. If the mother consumes caffeine, the baby also does through the placenta. As you surely know, caffeine is a stimulant that can cause insomnia and other side effects.

When you drink caffeine, your baby also ingests it. Thus, they may enter a phase of hyperactivity that also doesn’t allow them or you to sleep! For this reason, it’s usually advisable to minimize its intake.

5. If you drink too much coffee, you could become dehydrated

Coffee is stimulating and diuretic.

The caffeine in coffee, teas, and other drinks and foods is diuretic. Therefore, it increases the frequency of urination. People who drink a lot of caffeine may be at an increased risk of dehydration, which is one of the worst pregnancy complications.

6. Regular caffeine consumption could cause premature delivery

If you’ve ever heard this claim, you should know that there’s some truth behind it. However, only regarding high caffeine intake. The American College of Obstetricians and Gynecologists (ACOG) published that a high intake (more than 200 mg/day of caffeine) could increase the risk of preterm labor.


Check with your doctor regarding your caffeine consumption during pregnancy.
Currently, there’s no conclusive data on how much caffeine is safe for the baby during pregnancy. However, doctors generally consider that a moderate intake, meaning less than 300 mg a day, shouldn’t cause complications during pregnancy.

The medical recommendations on safe caffeine intake for a pregnant woman vary between 150 and 300 mg/day.

If the mother can’t avoid caffeine consumption during pregnancy, either because she’s used to consuming a lot of it or due to her cravings, the World Health Organization recommends moderating it. Either way, check with your doctor to receive their advice on this.
