Why does the pubic bone hurt at seven months of pregnancy?

Generally speaking, "yin bone" refers to the pubic bone, and pregnancy means gestation. Pubic pain occurring at seven months of pregnancy may be caused by hormonal changes during pregnancy, pelvic pressure, osteoporosis, pubic symphysis separation, pelvic arthritis, and other reasons. If discomfort occurs, timely medical attention is recommended. Detailed explanations are as follows:

1. Hormonal Changes During Pregnancy

Hormonal changes during pregnancy cause the ligaments and joints in the pelvic area to become softer and looser, possibly leading to pelvic instability and resulting in pubic pain. Engaging in mild to moderate exercise, such as prenatal yoga or water aerobics, can help strengthen the pelvic floor muscles and provide additional support.

2. Pelvic Pressure

As pregnancy progresses, fetal growth increases pressure on the pelvic area, causing pain in the pubic region. Using a pregnancy pillow to support the abdomen and legs can help relieve pressure on the pelvic area.

3. Osteoporosis

Inadequate calcium intake during pregnancy may lead to osteoporosis, decreased bone density, and an increased risk of fractures, which can cause pain in the pubic area. Symptoms may include height loss, kyphosis (hunchback), and increased susceptibility to fractures. Treatment may involve medications such as calcium carbonate D3 chewable tablets, calcium gluconate tablets, or calcium lactate tablets under a doctor's guidance.

4. Pubic Symphysis Separation

Some pregnant women may experience pubic symphysis separation due to trauma, multiple pregnancies, or polyhydramnios (excessive amniotic fluid), leading to more pronounced pain. Pregnant women should follow medical advice to use a pelvic correction belt to realign the pelvis, promote recovery of the pubic symphysis, and alleviate pain.

5. Pelvic Arthritis

Ligament laxity and weight gain during pregnancy may increase stress on the pelvic joints, triggering pelvic arthritis. Symptoms may include swelling, stiffness, and limited mobility in the pelvic area. Under medical guidance, medications such as ibuprofen sustained-release capsules, acetaminophen tablets, or diclofenac sodium sustained-release capsules can be used for treatment.

In daily life, pregnant women should maintain healthy lifestyle and dietary habits, engage in appropriate physical activity, avoid fatigue, and attend regular prenatal checkups.
