The hardening of the pregnant woman’s stomach on her due date may be caused by factors such as premonitory labor, labor onset, and placental abruption.
1. Pre-eclampsia: Before labor is initiated, there will be some symptoms that indicate impending labor, such as irregular contractions, the feeling of the fetus descending, redness and other symptoms, which is called pre-eclampsia. Because of the irregular contractions, it can lead to hardening of the stomach, usually the frequency of contractions is not consistent, the duration is short, the interval is long, the intensity of contractions does not gradually increase, often appearing at night and disappearing in the early morning.
2. Prolonged labor: the mother enters the labor process, which can be manifested by regular contractions, dilatation of the mouth of the uterus, the descent of the prenatal dew, and rupture of fetal membranes, etc. The contractions can also lead to a hard stomach. It can also lead to hardening of the stomach. Usually, the frequency of contractions is regular, the duration is prolonged, the interval is shortened, and the intensity of contractions gradually increases with the progress of labor.
3. Placental abruption: It refers to the partial or total detachment of the normally positioned placenta from the uterine wall after 20 weeks of gestation before delivery of the fetus. It can also cause uterine contractions, which are usually high in frequency and low in amplitude, and do not relax completely between contractions, resulting in a hardened stomach, usually accompanied by abdominal pain, vaginal bleeding and other symptoms.
There are many other causes of hardening of the stomach of pregnant women at the expected date of labor, which should be taken seriously, and timely consultation should be made to identify the cause of the disease, and further treatment or therapy as prescribed by the doctor.
