Osteoporosis
No vaccine availableDisease
A chronic bone disease in which bone mass, density, or structure declines, increasing the risk of fractures.
Symptoms
It is often silent until a bone breaks. Spine fractures may cause sudden back pain, loss of height, or a stooped posture; hip, spine, and wrist fractures are common sites.
Typical duration
Osteoporosis is a long-term condition. Bone density and fracture risk can be monitored and managed over years, but a prior fracture can have lasting effects.
How serious is it?
Fragility fractures can cause pain, disability, loss of independence, and serious complications, particularly after a hip fracture. Sudden severe back or hip pain after a minor fall needs prompt assessment.
Treatment & management
Management can include adequate calcium and vitamin D, weight-bearing and resistance exercise, fall prevention, stopping smoking, limiting alcohol, treating contributing conditions, and prescription medicines chosen according to fracture risk.
Vaccine: who and when?
Osteoporosis is not an infection, and there is no vaccine. Prescription osteoporosis medicines reduce bone loss or help build bone but are not vaccines.
