What causes a hard belly in the late stages of pregnancy?
Hardening of the abdomen in late pregnancy may be caused by physiological factors or pathological factors, such as false labor contractions or intrauterine infection. Specific details are as follows:
I. Physiological Factors
Prior to delivery, women commonly experience uterine contractions. As the uterus contracts, intra-amniotic pressure increases, leading to hardening of the abdomen during late pregnancy. This is generally considered a normal physiological phenomenon and typically requires proceeding to a qualified medical facility for childbirth.
II. Pathological Factors
1. False Labor Contractions (Braxton Hicks Contractions)
In late pregnancy, the uterine muscles become more sensitive, which may lead to abnormal contractions causing the aforementioned symptom. However, if the cervix remains closed and the frequency of contractions does not meet the criteria for true labor, this is classified as false labor. If false contractions occur frequently, breathing techniques may help alleviate symptoms.
2. Intrauterine Infection
If a pregnant woman becomes infected with pathogens such as cytomegalovirus or rubella virus during pregnancy, it may result in intrauterine infection. The uterine cavity may then exhibit this symptom due to stimulation by inflammatory factors. Treatment should follow medical advice and may include medications such as Moxifloxacin Hydrochloride Injection or Clindamycin Phosphate for Injection.
It is recommended that any discomfort during late pregnancy be promptly evaluated by a healthcare provider.
