Sacroiliac Joint Dysfunction in Pregnancy

The sacroiliac joints sit at the back of the pelvis and transfer load between the trunk and legs. Pregnancy can change posture, walking mechanics and the way the pelvic joints share movement. This may produce one-sided or central buttock pain, discomfort when turning in bed, climbing stairs, standing on one leg, or getting in and out of a car. These symptoms do not by themselves identify the cause, and pelvic, hip, back, or pregnancy-related conditions can feel similar.

Tell your maternity clinician and ask for a physiotherapy assessment if pain affects daily activities. A pregnancy-informed plan may include pacing, comfortable position changes, gentle strengthening, support for getting dressed, and advice about sleep positions. Keep loads close to your body, avoid sudden twisting, and take smaller steps on stairs. Do not start medication, a brace, or vigorous exercises without checking that it suits your pregnancy and medical history.

Contact your maternity team promptly for bleeding, fluid leakage, regular contractions, fever, severe abdominal pain, or reduced fetal movement according to your maternity advice. Seek urgent assessment for new leg weakness, numbness around the saddle area, or loss of bladder or bowel control. For musculoskeletal pain, arrange review when walking, sleep, or basic tasks remain difficult despite activity changes.

Could this pain be coming from the sacroiliac joints or another pelvic structure? Which exercises and positions are suitable at my stage of pregnancy? Would a support belt help me? Which pain-relief options are appropriate for me?
