osteoporosis in children

Overview

Osteoporosis in children is a rare condition in which bones become thin and weak and are more likely to break. It is sometimes called 'juvenile osteoporosis' when it affects growing children.

No. Osteoporosis in children is rare. Most children have healthy bones even if they break a bone from a fall.

It mostly affects children with other health problems, such as juvenile arthritis, kidney disease, inflammatory bowel disease, or eating problems, and children who take steroid medicines for a long time. In some cases, it is passed down in families.

Symptoms

Common symptoms

• Often no symptoms at all until a bone breaks
• Bones that break with little force or during normal movement
• Dull bone pain, often in the back
• Fractures that seem to heal slowly

Symptoms in children

• A fall from standing height that causes a fracture
• Pain in the back, hips, or legs when active
• Limping or not wanting to put weight on a leg
• Trouble keeping up with usual play or sports

Causes

Main causes

• Another medical condition such as juvenile arthritis, inflammatory bowel disease, kidney disease, cystic fibrosis, or hormone problems
• Long-term use of steroid medicines
• A genetic condition that affects bones, such as osteogenesis imperfecta
• Poor bone growth due to limited movement, poor nutrition, or low vitamin D and calcium

Risk factors

• Chronic illness or disability that limits weight-bearing activity
• Long-term steroid therapy
• Delayed puberty or low hormone levels
• Low calcium or vitamin D intake
• Family history of fragile bones

When to see a doctor

See a doctor urgently if:

• If your child has a broken bone from a fall or minor knock and the doctor hasn't already assessed their bone health
• If your child is limping or refusing to move a limb for more than two days
• If your child has back pain that doesn't improve with rest

Book a routine appointment if:

• If your child has a chronic condition or takes steroid medicines, ask at regular check-ups about bone health
• If you have family history of osteoporosis or repeated fractures, mention it to your doctor
• If you are concerned about your child's diet, activity, or growth, talk with your pediatrician

Diagnosis

Doctors diagnose childhood osteoporosis by looking at the child's full health picture: medical history, family history, diet, activity, previous fractures, and imaging. A formal diagnosis usually requires a low bone density result and a history of fractures.

Tests that may be done

• DXA (dual-energy x-ray absorptiometry) scan to measure bone density, using special child-friendly reference standards
• X-rays to check for past breaks and bone health
• Blood and urine tests to check calcium, vitamin D, hormones, and other markers

What to expect at your appointment

Tests are painless and usually done at a hospital clinic. A bone scan takes about 10–20 minutes while the child lies still. The doctor will explain results and may refer your child to a bone or pediatric specialist.

Treatment

Treatment for childhood osteoporosis is as individual as your child. It usually starts by treating the underlying condition, improving nutrition and activity, and preventing falls. In some cases, a specialist may discuss bone-strengthening medicines with you.

Self-care at home

• Eat a balanced diet with calcium-rich foods and enough vitamin D.
• Include safe, weight-bearing activities like walking, dancing, or climbing stairs, if your child's team agrees.
• Make the home safer: clear walkways, add mats in the bathroom, improve lighting, and avoid clutter.
• Encourage good posture and safe lifting techniques for older children.
• Work with teachers and care teams to allow pain-free breaks during the school day.

Medical treatments

A specialist may treat the medical condition causing bone weakness, adjust medicines that harm bones (only if appropriate), or use a type of bone-strengthening treatment for severe cases. Children with osteoporosis need care from a specialist bone team. Never give adult bone medicines to a child.

When is surgery considered?

Surgery is rarely needed. A surgeon might be involved if a break doesn't heal well or if there is a deformity that affects movement, but most children with osteoporosis do not need surgery.

Living with this condition

A child with fragile bones can still enjoy school, friendships, and hobbies. The goal is to keep them safe while letting them move, learn, and have fun. Small changes can make a big difference.

Lifestyle tips

• Use fall-prevention rugs, handrails, and sturdy shoes.
• Choose activities with low impact, like swimming, cycling, or yoga, if the doctor agrees.
• Plan rest breaks during long school days and sports trips.
• Keep a daily routine with enough sleep, sunlight, and healthy snacks.
• Let the child be part of decisions about activity and school accommodations.

Diet and exercise

Every day aim for a varied diet with calcium-rich foods (milk, yogurt, cheese, tofu, leafy greens, almonds, and fortified drinks) and vitamin D (sunlight, oily fish, eggs, and fortified foods). If your child is restricted in range or cannot eat certain foods, ask a dietitian for help.

Mental health and emotional wellbeing

Living with a bone condition can bring worry, frustration, or feelings of being different. It's okay to ask for help. Encourage conversations, keep teachers informed, and involve a counselor if your child seems withdrawn or anxious about safe activities.

Prevention

Not always, especially if a child has a genetic condition or another illness. But making bones as strong as possible through good nutrition and activity may help reduce break risk.

Vaccines

Routine childhood vaccines protect against illnesses that can affect general health and movement. They do not prevent osteoporosis, but they help keep children well enough to stay active.

Screening programmes

Bone density screening is not recommended for all children. A doctor may consider it if a child has repeated fractures, uses long-term steroid medicines, or has a chronic disease linked to weak bones.

Complications

If left untreated

• More frequent or repeated fractures from everyday activities
• Chronic bone pain and difficulty walking or standing
• Bone deformities or curving of the spine
• Missed school, low confidence, and emotional stress

Long-term outlook

Many children with osteoporosis can stabilize and improve with proper treatment and support. The bone-building years are a real opportunity for gain, and a specialist team can help families make the most of them.
