Pregnancy can alter a woman's constitution, potentially leading to a weakening of her physical state. During pregnancy, the body's immune mechanisms are suppressed, resulting in a decrease in immune function. Additionally, the severity of nausea and vomiting during pregnancy varies, which may cause a temporary decline in physical condition for pregnant women in the short term. However, these changes are physiological and temporary. As nausea and vomiting during pregnancy significantly improve or disappear, the constitution gradually returns to normal. Women preparing for pregnancy or already pregnant should appropriately focus on physical exercise and rest adequately to avoid overexertion. They should consume more fresh fruits and vegetables in their diet, along with foods rich in coarse fiber, which aids gastrointestinal digestion and prevents constipation. Meanwhile, it is essential to supplement with appropriate amounts of folic acid and calcium tablets to prevent neural tube defects in the fetus and promote fetal bone development. Regular prenatal check-ups should be conducted during pregnancy. Excessive sexual activity should be avoided in the second trimester, and sexual activity should be abstained from in the first and third trimesters to prevent abdominal pain, bleeding, miscarriage, or preterm delivery.
