What diseases cause weak bones?

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced.

What are the common bone diseases?

Common Bone Disorders

• Osteoporosis. This common disease occurs when bones become weak due to changes in bone mineral density and mass, causing a higher risk for fractures.

• Rheumatoid arthritis.
• Gout.
• Bursitis.
