Does drinking milk tea in the late stages of pregnancy affect the fetus?

In the late stages of pregnancy, if blood sugar levels and digestive function are normal, drinking milk tea is generally acceptable and will not have a significant impact on the fetus. However, if blood sugar is high or nausea and vomiting are present, milk tea should usually be avoided, as it may increase the risk of premature birth or excessive fetal growth.

1. No adverse effects

Milk tea is made from milk, tea, and sugar, containing carbohydrates and trace elements. In late pregnancy, if blood glucose levels are normal and digestive function is healthy—without gastrointestinal discomfort such as nausea, vomiting, or acid reflux—drinking milk tea in moderation is generally safe and unlikely to affect the fetus. However, milk tea often contains preservatives and additives, so excessive consumption should be avoided.

2. Potential adverse effects

If a pregnant woman has elevated blood glucose levels during pregnancy or experiences persistent nausea and vomiting throughout gestation, milk tea is typically not recommended. Due to its high sugar content, milk tea can further raise blood glucose levels, increasing the risks of difficult labor and fetal macrosomia (excessive fetal size). Additionally, tea polyphenols and caffeine in milk tea may irritate the gastrointestinal tract, worsen morning sickness, trigger frequent uterine contractions, and thereby increase the risk of preterm delivery.

It is recommended that diet in late pregnancy be light and balanced. Pregnant women should consume nutritious foods, especially those rich in high-quality protein, and avoid strong stimulants such as concentrated tea and coffee. Fetal movements should be closely monitored, and any concerns or discomfort should prompt immediate medical consultation at a hospital.
