What should you know about pediatric osteoporosis?

Children normally build bone while growing, so low bone strength can affect movement, activity, and fracture risk. Some children have an underlying disorder, limited mobility, nutritional difficulty, hormonal problem, or prolonged medicine exposure; sometimes no single cause is found. Repeated fractures after minor forces, bone pain, back pain, or reluctance to walk can prompt evaluation, but these signs also have other explanations.

Assessment may include growth and puberty history, medicines, nutrition, physical examination, blood tests, and a [Bone Density Scan](/treatments/diagnostics-and-screening/bone-density-scan/). A scan is interpreted with the child’s age, body size, and development rather than adult labels alone.

Keep specialist appointments and tell the team about fractures, pain, falls, diet, activity, and medicines. Do not stop prescribed treatment suddenly or start supplements without advice. The plan may address the underlying condition, safe weight-bearing activity, fall prevention, and nutrition. Depending on the findings, clinicians may consider [Vitamin D Supplementation](/treatments/medical-management/vitamin-d-supplementation/), [Calcium Supplementation](/treatments/non-surgical-orthopedics/calcium-supplementation/), or [Bisphosphonate Therapy](/treatments/non-surgical-orthopedics/bisphosphonate-therapy/).

Activity should be adapted to fracture history and bone strength. A physiotherapist can help maintain mobility and strength while avoiding high-impact loads during vulnerable periods.

Seek urgent care after a fall or injury causing severe pain, deformity, inability to bear weight, new weakness, or loss of bladder or bowel control. Arrange prompt review for persistent back pain, repeated fractures, new limping, or pain that wakes the child. A [Stress Fracture](/conditions/stress-fracture/) or [Vertebral Compression Fracture](/conditions/vertebral-compression-fracture/) requires clinical assessment, not home diagnosis.

What could be affecting my child’s bone strength? Which tests are needed? What activity, nutrition, and medicines are appropriate? How should we respond to pain or a suspected fracture?
