When the pelvic bones begin to diverge pregnancy

When do the pelvic bones begin to split during pregnancy?

Why the pelvis hurts during pregnancy

All the pelvic organs of a pregnant woman in the third trimester experience pressure from the growing uterus. Therefore, the pelvic bones ache. But such pain can appear in women and in early terms. In this case, the cause is the stretching of the round uterine ligaments. After all, the uterus in the pelvis is fixed by a set of ligaments. They do not allow the main body of the reproductive system to deviate forward. These ligaments are formed from connective tissue, and it is stretched very poorly. But so it is already inherent in nature that the uterus of the future mother increases, and the connective tissue should stretch. And in the woman's blood there is a special hormone relaxin, which increases the extensibility of tissues.

And yet, the pain of stretching is worried more or less by a woman throughout her pregnancy. Sometimes they can be very sharp, and when you change the position of the body disappear. Most women are already getting used to such pains in the last weeks of bearing a child.

About a divergence of pelvic bones

Note that from 17-20 weeks of pregnancy changes in the pelvis are reflected in the gait of a woman. And it happens because the pelvic bones diverge. They become mobile. This gradual preparation of the female body for childbirth. The woman begins to tilt the body back slightly when walking. It turns out that her tummy seems to bulge forward, and the gait becomes similar to the duck. It is during this period of gestation that future mothers, who still walked in shoes with heels, refuse it. After all, movement on his heels becomes very uncomfortable.

The pelvic bones themselves do not change. That's just the amount of calcium in them can decrease. And this is due to the fact that calcium is being intensively taken away by the developing baby. If the mother consumes a little calcium-containing foods, then the pain in the pelvis can be felt more. The discrepancy of the pelvic bones during the bearing of the child occurs due to a change in the structures of the soft tissues, that is, the symphysis-of the dense cartilage that connects the pelvic bones in the front. The mobility of the symphysis just allows the head of the child to pass through the birth canal of the mother.

It is the divergence of the bones that causes pain in the pubic region and symphysis. If the female body is deficient in calcium, then symphysitis develops.

The widening of the pelvic bones also affects the coccyx. A small bone with a sacrum has an inactive joint. As a rule, it is rejected inside the pelvis. The coccyx during delivery could prevent, for example, dislocating, if not relaxation of the sacrococcygeal joint. In future mothers, this small bone deviates posteriorly. Therefore, it does not hinder the advancement of the baby by generic pathways. The pain caused by the mobility of the coccyx right before delivery increases in sitting position, especially on a soft surface.

The discrepancy of the pelvis also concerns the lumbosacral articulation. In this area of ??the musculoskeletal system, mobility increases. This is already at the beginning of the third trimester. The pelvis generates a single plane in the process of delivery with the spine, and the above articulation acquires greater mobility.

If a woman gives birth herself, without the help of midwives, she intuitively accepts those postures in which the advancement of the child is not difficult, that is, squats, leaning forward, leaning on something. In the maternity home, with the purpose of straightening the axis of the birth canal, special pillows (polishers) are placed under the buttocks. However, even before the woman gets to the hospital, the mobility of the lumbosacral joint becomes a cause of pain. They are more felt by those women, whose back muscles are weak. It's not for nothing that they say that it's easier for the athletes to give birth. Also, pains in the pelvis before birth can be strongly felt by those women who had problems with the spine before pregnancy: their pelvic bones disperse more heavily and more slowly.

After the birth, pain in the pelvis disappears for a period of two to six months.
