IBS in pregnant women is a thrombotic disorder that necessitates hospitalization during the onset of the disease. It has a significant impact on the health of pregnant women and can affect the development of the embryo, causing fetal retardation, stillbirths, and habitual miscarriages. Therefore, when a pregnant woman is diagnosed with IBS, it is necessary to be hospitalized for observation and monitoring under the supervision of a doctor to understand the development of the embryo. When pregnant women are diagnosed with thrombophilia, they need to be treated with anticoagulants, such as low molecular heparin, as soon as possible, with the aim of preventing thromboembolism. If there is a combination of gestational hypertension and gestational diabetes mellitus, anticoagulant therapy is needed along with management of the primary disease. If a pregnant woman is found to have thrombophilia and needs to use medication, it should be carried out under the guidance of a professional physician, so as not to take medication without authorization to affect the development of the embryo, and to be discontinued in a timely manner after the condition has recovered.
