Sacroiliac Joint During Pregnancy

One of the most common complaints during pregnancy is lower back pain. Most expectant mothers assume that the pain is caused by the lopsidedness of the body’s posture as a result of the growing uterus. Many put it down to sciatica related pain. However, this is not always the case. Lower back pain, especially towards the latter half of the pregnancy could be caused by sacroiliac joint dysfunction. The sacroiliac joint is the joint that lies in between the sacrum (which supports the spine) and the ileum (which in turn support the sacrum), in the pelvic region.

The sacroiliac joints – on the left and the right of the spine are L-shaped and are held in place by strong ligaments that provide a limited range of movement.

During pregnancy, a number of hormonal changes take place in a woman’s body. The production of estrogen, progesterone and relaxin increases manifold and this alters the bony pelvis to cope with pregnancy and the widening of the sacroiliac joints to facilitate childbirth is the main intention. Relaxin relaxes the joints, allowing greater movement of the sacroiliac joints. When the movement of these load bearing joints becomes too much, it results in instability in its normal functioning. Affected functioning of the sacroiliac joint during pregnancy causes a strain on the lower back thus leading to sacroiliac joint back pain during pregnancy. Pain related to the sacroiliac joint during pregnancy magnifies when the body posture is altered due to the weight of the expanding uterus.

The symptoms of sacroiliitis during pregnancy include a shooting or stabbing pain in the lower back, buttocks as well as the thighs, similar to that experienced in the case of sciatica. The pain experienced tends to increase when walking and climbing as the hips move and this may result in limping. At times, the pain is unbearable thus restricting movement. Some women find it difficult to lie down for a long time and this increases the discomfort. Self medication is not recommended at all as it could worsen the condition as well as affect the pregnancy. Consulting a doctor with regard to any pain is highly advisable. Sacroiliitis during pregnancy should not be ignored as it could lead to more serious complications, if left untreated.
