What should you know about osteoporosis in pregnancy?

Pregnancy-related osteoporosis may involve sudden back pain, hip or groin pain, reduced mobility or a fracture after a modest strain. Back discomfort is common in pregnancy, so persistent, severe or changing pain needs a clinical assessment. Symptoms do not establish the diagnosis; clinicians also consider other causes such as muscle strain, joint problems or a stress fracture.

Evaluation is tailored to pregnancy and may include an examination, selected imaging and blood tests. A bone density scan is usually considered only when the expected benefit outweighs concerns about timing and exposure. The obstetric and musculoskeletal teams can coordinate the safest approach for parent and baby.

Tell your maternity clinician promptly about new severe back, hip or groin pain, difficulty walking, or pain after lifting or a small fall. Until assessed, avoid heavy lifting and high-impact activity that increases pain, but follow advice on gentle movement to prevent stiffness. Use support when walking and ask for help with tasks that feel unsafe.

Nutrition, vitamin D status and calcium intake may be reviewed. Any supplement or medicine should be chosen with the pregnancy team because some osteoporosis medicines are not suitable during pregnancy or breastfeeding. A plan may change after delivery as recovery, feeding and future pregnancy goals are considered.

Seek urgent assessment for inability to bear weight, severe hip or back pain, a fall with ongoing pain, a visible deformity, new weakness or numbness, or loss of bladder or bowel control. Contact your maternity team for pain that is persistent, worsening or stopping sleep or normal movement. Do not wait for a routine visit if a fracture is suspected.

What could be causing this pain, and do I need imaging now? How can my activity be modified safely? Should calcium or vitamin D be checked? Which pain medicines and supplements are suitable in pregnancy or breastfeeding? Who will coordinate follow-up after delivery?
