Bone mass, both in women and men, continues to increase till the late twenties, which is when it reaches its peak. However, women accumulate less skeletal mass than men do during their growth period. This makes them susceptible to bone degeneration as soon as they enter their 30s. The rate of bone loss varies from individual to individual, but is broadly similar in men and women. Mention other factors as well which contributes to bone loss.
If women fail to ensure intake of the recommended micronutrients after they reach their 30s, chances are their bones may start becoming porous and fragile. While the short-term consequences of this include bone fractures, in the long term it could lead to osteoporosis and other bone-related complications.
