Gestational diabetes is one of the more common complications during pregnancy. Poor blood sugar control can affect both the mother's and the baby's health. If a mother has a history of gestational diabetes, the risk of developing it again during a second pregnancy is significantly higher. Therefore, experts recommend that expectant mothers with a history of gestational diabetes get their blood sugar checked before conceiving a second child.
1. Increased Risk of Recurrence with Second Pregnancy
Research indicates women with a history of gestational diabetes are more susceptible to developing it again in subsequent pregnancies. Studies show that while gestational diabetes occurs in 1%-5% of pregnancies in China, recurrence rates soar to 33%-69% in repeat pregnancies.Experts advise mothers with gestational diabetes to undergo an OGTT follow-up test 42 days postpartum. If planning a second pregnancy, it is best to visit a hospital beforehand to check for hyperglycemia. Pregnancy should only occur once blood sugar is under control to reduce the risk of recurrence.
2. Strict Dietary Control is Key to Preventing Gestational Diabetes
Given the high recurrence rate of gestational diabetes, women who experienced it during their first pregnancy should prioritize blood sugar management from the outset when preparing for a second pregnancy. This involves avoiding blood sugar spikes, particularly through sensible dietary control.During the first trimester, to alleviate morning sickness, eat light meals in smaller, more frequent portions. Ensure adequate high-quality protein through meat, eggs, dairy, and soy products, and consume plenty of vegetables to guarantee sufficient vitamin and mineral intake.
Gestational diabetes primarily occurs during the second and third trimesters. Elevated blood sugar during this period can lead to excessive fetal growth in the womb, resulting in macrosomia or increased cesarean section rates. Therefore, expectant mothers must strictly control their diet during the second and third trimesters and avoid overeating.It is recommended that pregnant women supplement their three main meals with 2-3 additional light meals daily. When selecting foods, prioritize those with a low glycemic index, such as buckwheat noodles or pasta. Overall, daily meals should aim to include all eight major food groups: grains, meat/fish/eggs, dairy, beans, vegetables, fruits, oils, and nuts.
3. Combine Dietary Control with Moderate Exercise
Alongside dietary management, expectant mothers should incorporate appropriate physical activity. Engage in gentle exercises like walking or light calisthenics one hour after meals. Avoid strenuous workouts, and limit exercise sessions to 20-30 minutes. Monitor for uterine contractions during activity; cease immediately if fatigue or contractions occur.
