A cup of coffee contains about 100 to 150 milligrams of caffeine. Foreign data show that caffeine has the risk of causing fetal cleft palate and other malformations. Even with a daily intake of less than 150 milligrams of caffeine, the risk of giving birth to low birth weight babies is 1.5 times higher.

The caffeine ingredients it contains can stimulate pregnant women, accelerate their heartbeat and raise their blood pressure. For pregnant women with hypertensive disorder complicating pregnancy, the risk is greater, which can lead to coronary heart disease and increase the possibility of myocardial infarction. Research from Boston University in the United States shows that women who drink more than five cups of coffee a day have a 70% increased risk of heart attack, and the risk increases with drinking.

An Australian bioscience research team recently found that excessive caffeine is one of the leading causes of miscarriage in pregnant women. Many previous studies have shown that caffeine may affect human conception. The team's findings show that caffeine can affect the conversion of estrogen to progesterone, thereby preventing fertilized eggs from successfully implanting in the womb. If caffeine acts together with alcohol and nicotine, the side effects will be doubled. So women who drink coffee and drink too much are more likely to have a spontaneous miscarriage. In addition to coffee, cocoa, chocolate and many medicines such as painkillers and stimulants are also high in caffeine.

Caffeine ingredients make people in a state of excitement, inhibit sleep, it is easy to disturb the normal rest of pregnant women. Tea also contains a large amount of tannic acid that can combine with iron in food to form a compound that cannot be absorbed by the body. If pregnant women drink too much strong tea, it is possible to cause pregnancy anemia, and it will also leave the fetus with the legacy of congenital iron deficiency anemia.
