2 can prevent cesarean section incisions from splitting by taking a longer time between pregnancies, eating well and taking regular checkups. 1. Longer interval between pregnancies: it usually takes 3-6 months after the operation for the uterine incision scar to mature, and the scar usually has the best elasticity in 2-3 years, so it is generally recommended to carry a second child more than 2 years after the cesarean section. 2. Reasonable diet: You can eat a light diet and take appropriate vitamin and calcium supplements to prevent excessive weight gain within a short period of time, which may lead to excessive growth of the uterus, thus causing rupture of the cesarean incision. 3. Timely labor inspection: Labor inspection should be conducted on time to detect the existence of abnormalities and take timely treatment. If you have 2 babies after cesarean section, it is recommended that you have regular checkups.
