Introduction

In late pregnancy, a hard and slightly painful abdomen may be caused by fetal movement, false labor contractions (Braxton Hicks contractions), or preterm labor, which requires targeted treatment. Irregular and infrequent uterine contractions are considered false labor contractions. At this time, the increase in progesterone leads to an increased number of oxytocin receptors in the uterus, making the uterus more sensitive and resulting in this phenomenon. It is recommended that pregnant women change their body position.

During the late stages of pregnancy, a hard and slightly painful abdomen may be caused by fetal movement, false labor contractions in late pregnancy, or preterm labor. Targeted treatments are required depending on the cause, with specific details as follows:

1. Fetal Movement

In the late stages of pregnancy, the fetus is usually relatively large and its movements within the uterus can cause the uterine smooth muscles to stretch, resulting in a hard feeling in the abdomen. This is a normal physiological phenomenon and generally does not require excessive concern, as it will resolve on its own after a period of time.

2. False Labor Contractions in Late Pregnancy

Irregular and infrequent uterine contractions are considered false labor contractions. At this stage, increased levels of progesterone lead to a rise in oxytocin receptors in the uterus, making it more sensitive and causing this phenomenon. Pregnant women are advised to change their posture regularly, avoid prolonged standing or sitting, and may apply a warm water bottle to the lower abdomen for relief when appropriate.

3. Preterm Labor

If the fetus in utero is affected by external forces, it may trigger preterm labor. Preterm labor causes uterine contractions, leading to this symptom. In such cases, prompt medical attention is recommended to prevent adverse effects on the health of both mother and baby.

In addition to the above, an impending delivery can also cause abdominal tightness during late pregnancy. When this occurs, pregnant women should pay close attention and seek hospital evaluation to determine the underlying cause and receive appropriate treatment.

Is it a sign that labor is near when the belly feels hard at full term?

At full term, a hardening of the abdomen may be a sign of impending labor, or it could be caused by false labor contractions (Braxton Hicks contractions). If the hardening lasts longer, occurs at shorter intervals, or is accompanied by vaginal discharge of bloody secretions, these are definite signs of true labor onset. In late pregnancy, as uterine sensitivity increases, the abdomen may easily feel tight or hard when stimulated by external factors—this is a normal physiological phenomenon.

Patients with atrophic gastritis experience abdominal bloating and a hard-feeling abdomen.

The term "belly" refers to the abdomen. Atrophic gastritis is a chronic inflammation of the gastric mucosa that leads to a reduction and atrophy of mucosal cells. In general, symptoms such as bloating and abdominal rigidity in patients with atrophic gastritis may be caused by factors including gas accumulation in the stomach, food intolerance, acid reflux, heartburn, severe inflammation and ulcers, or gastric muscle dysfunction. These can be treated with medications or surgery.
