Causes of pelvic pain in late pregnancy

Many women in late pregnancy suffer from pelvic pain. Pelvic pain is a particular worry for many women in late pregnancy, who are worried that they may have a disease, so they want to fully understand the causes of pelvic pain in late pregnancy. The following content provides a detailed introduction, so women who experience pelvic pain in late pregnancy can have a comprehensive understanding.

reason

This kind of back pain is caused by the enlargement and bulging of the abdomen, which causes the body's center of gravity to shift backward and causes tension in the lower back muscles. It is a common symptom during pregnancy and is not a disease.

The human pelvis is composed of the sacrum, coccyx and left and right hip bones. The bones of the pelvis are connected by the pubic symphysis in the front of the pelvis and the sacroiliac joints, sacrococcygeal joints and two pairs of sacrotuberous ligaments and sacrospinous ligaments in the back. The pelvis, which is tightly surrounded by several bones, acts like a single bone. For women who are not yet pregnant, the pelvic joints are inactive and therefore pain does not occur. Once a woman is around 10 weeks pregnant, her ovaries secrete a substance called relaxin, which makes the fibrous cartilage and ligaments of the sacroiliac joint and pubic symphysis become loose and soft, and the sacroiliac joint and pubic symphysis become wider and more mobile. By the late stages of pregnancy, the pubic symphysis widens by an average of 0.3-0.4 cm, and the sacrococcygeal joint moves posteriorly by up to 2 cm, to facilitate the fetus's passage through the bony birth canal during delivery. However, if the ligaments are too relaxed, the pubic symphysis will separate, the sacrum will not be able to fix the left and right iliac bones, and the pelvis will lack stability. When pregnant women walk, sit, go up and down stairs, or turn over, the bones of the pelvis will move separately, pulling on the fibrous cartilage and ligaments between the pubic bones, causing pain in the pubic and sacroiliac joints. In severe cases, the pain will radiate to the groin or perineum, and even make it difficult for pregnant women to move.

Solution:

1. When standing, tilt your pelvis slightly, lift your upper body, and drop your shoulders slightly backward to avoid standing for long periods of time.

2. When sitting, your lower back should be comfortably against the chair back, your upper body should be straight, and you should not sit on a bench without support for a long time.

3. Relax your whole body when walking and do not wear high heels.

4. You can sleep in a curled-up side-lying position, and place a pillow under your knees when lying on your back.

Pelvic pain in the late pregnancy must be taken seriously by pregnant women, because this situation may cause miscarriage and affect their lives. Therefore, many women with such symptoms should go to the hospital as soon as possible for a comprehensive examination after understanding the cause of the symptoms, and receive treatment as soon as possible after finding out the cause.
