Saddle-shaped uterus is an abnormal development of the uterus, mainly manifested as a saddle-shaped or curved concave uterine fundus, which is a kind of malformed uterus and belongs to congenital developmental abnormalities. Generally, the specific situation is determined by ultrasound examination, which causes different results depending on the severity of the condition. In the case of simple abnormal uterine morphology, there is still a chance of pregnancy, and no special treatment is usually necessary, but attention needs to be paid to the treatment of the settled fetus after pregnancy. If there are also abnormalities in the uterine cavity, it can affect the fertilized egg’s implantation and cause miscarriage or infertility, thus affecting normal pregnancy. Pregnant women need to be admitted to the hospital for examination as soon as symptoms of preterm abortion appear. If the symptoms do not improve after 2 weeks, it indicates that the embryo may be developing abnormally and the pregnancy should be terminated if necessary. Therefore, pregnant women with saddle-shaped uterus must intensify fetal preservation after pregnancy. At the same time, we should pay attention to the following aspects in our daily life: 1. we should take more bed rest, avoid sex, and avoid strenuous activities and long hours of exertion; 2. we should pay attention to eating less and more meals, mainly light and high protein, and avoid spicy and stimulating food; 3. we should do ultrasound and other maternity examinations regularly, and pay close attention to fetal heartbeat and fetal movement; 4. we should keep regular work and rest time, and avoid emotional fluctuations.
