Osteoporosis - Causes. Osteoporosis causes bones to become less dense and more fragile. Some people are more at risk than others. Bones are at their thickest and strongest in your early adult life and their density increases until your late 20s. You gradually start losing bone density from around the age of 35.
The course of osteoporosis can be divided into four stages: 1  Stage 1 - Begins at about age 35 before osteoporosis is detectable. 2  Stage 2 - Occurs between ages 35 and 55 when osteoporosis becomes detectable with special tests. 3  Stage 3 - Can begin as early as age 45 and is characterized by bone fractures.
