Osteoporosis : Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses like bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue, which is constantly being absorbed and replaced. Osteoporosis occurs when the creation of new bone doesn't keep up with the removal of old bone.
Symptoms
Signs and symptoms include:
• Back pain, caused by a fractured or collapsed vertebra
• Loss of height over time
• A stooped posture
• A bone fracture that occurs much more easily than expected
Treatments
For both men and women, the most widely prescribed osteoporosis medications are bisphosphonates. Examples include:
• Alendronate (Fosamax, Binosto)
• Risedronate (Actonel, Atelvia)
• Ibandronate (Boniva)
• Zoledronic acid (Reclast, Zometa)
