Can pregnant women eat watermelon, and will it affect the fetus?

Generally, pregnant women can consume watermelon in moderation, which typically has no adverse effects on the fetus. The detailed analysis is as follows:

Watermelon is rich in vitamin C, B-complex vitamins, potassium, and various other vitamins and minerals. These nutrients contribute to the health of both the pregnant woman and the fetus. Vitamin C helps enhance the pregnant woman's immunity and promotes the development of the fetus's bones and teeth; potassium benefits the maintenance of normal heart rhythm and muscle function in pregnant women and supports the development of the fetal nervous system.

Watermelon has a high water content, and moderate consumption by pregnant women helps replenish bodily fluids, increase urine production, and promote urination, thereby alleviating possible edema symptoms during pregnancy. Additionally, it can help pregnant women prevent and relieve constipation. During pregnancy, women may experience changes in taste preferences. Watermelon, being sweet and juicy with good flavor, can stimulate appetite to some extent, helping pregnant women consume more nutrients.

However, it should be consumed in moderation. Watermelon has a relatively high glycemic index. If a pregnant woman has gestational diabetes or unstable blood sugar control, excessive consumption of watermelon may lead to a rapid increase in blood sugar levels. This could not only affect the woman's own health but also potentially harm the fetus—for example, causing fetal macrosomia, increasing the risk of difficult labor, and even possibly affecting fetal lung development. Pregnant women with conditions such as gestational diabetes or weak gastrointestinal function should consume watermelon cautiously under a doctor's guidance.
