Why should pregnant women avoid eating bitter melon?
Generally speaking, the reasons why pregnant women should avoid eating bitter melon include triggering diarrhea, stimulating uterine contractions, affecting nutrient absorption, allergy risks, and individual physical differences. A detailed analysis is as follows:

1. Triggering Diarrhea
Bitter melon has a cold nature and can easily irritate the gastrointestinal tract after consumption, especially for pregnant women with weak spleen and stomach function, making them more prone to diarrhea. Diarrhea not only affects the health of the pregnant woman but may also trigger uterine contractions, increasing the risk of miscarriage or premature birth.
2. Stimulating Uterine Contractions
Bitter melon contains an alkaloid called quinine, which can stimulate uterine activity. Excessive consumption of bitter melon by pregnant women may stimulate uterine contractions, leading to miscarriage or premature birth. Although the quinine content in bitter melon is relatively low, pregnant women should still avoid consuming large amounts as a precaution.
3. Affecting Nutrient Absorption
Certain components in bitter melon may interfere with the absorption of nutrients such as calcium in pregnant women. In the late stages of pregnancy, women are particularly prone to calcium deficiency; therefore, bitter melon intake should be minimized to avoid negatively affecting fetal bone development.
4. Allergy Risk
Some pregnant women may be allergic to bitter melon, and symptoms such as rashes or difficulty breathing may occur after consumption. Allergic reactions not only affect the health of the pregnant woman but may also have adverse effects on the fetus.
5. Individual Physical Differences
Pregnant women vary in physical constitution, and some may inherently be unsuitable for consuming cold-natured foods. Pregnant women with cold-deficient constitutions may experience increased internal coldness after consuming bitter melon, which could affect their overall health.
Pregnant women should consume bitter melon cautiously during pregnancy to avoid adverse effects on the health of both the fetus and themselves.
