What is osteoporosis?

Osteoporosis is a disease of bone in which bone mineral density (BMD) is reduced and bone microarchitecture is disrupted. Osteoporotic bones are susceptible to fracture. Osteoporosis is defined as either a bone mineral density 2.5 standard deviations below peak bone mass (20-year-old person standard) as measured by DEXA or any fragility fracture. While treatment modalities are becoming available, prevention is still the most important way to reduce fracture. Due to its hormonal component, more women suffer from osteoporosis than men.

Osteoporosis is a disease in which bones become fragile and more likely to break.

a bone decease.. uhm, its common to older people.
In old age, bones can start to crack, break and become more brittle but if you don't take calcium in your younger years, you'll become immobile.
