Why are twins more likely to be born prematurely?

Twins are prone to premature birth, generally due to factors such as premature rupture of membranes or the onset of uterine contractions. In twin pregnancies, the intrauterine pressure is relatively high, which may lead to preterm labor. Since twins require more nutrients, it's important during pregnancy to consume more nutritious foods, such as nuts and vitamin-rich fruits, to prevent the mother from becoming too weak and ensure adequate nutrient supply to the fetuses, thereby reducing the risk of premature birth.
