Type 2 Primary Osteoporosis is primarily caused by which factor?

• A. Genetic predisposition
• B. Ovarian dysfunction
• C. Normal aging process
• D. Excessive physical activity

Answer: (C)

The primary cause of Type 2 Primary Osteoporosis is indeed the normal aging process. As individuals age, especially post-menopausal women and older men, there is a natural decline in bone density and strength due to several physiological changes.

With advancing age, bone remodeling becomes imbalanced; bone resorption (the process by which bone is broken down) begins to outpace bone formation. The body may also absorb less calcium from the diet due to changes in gastrointestinal function, and the production of hormones that are important for bone health, such as estrogen and testosterone, declines. This makes older individuals particularly susceptible to osteoporosis, highlighting the significant role that aging plays in the onset of this condition.

Genetic predisposition can contribute to bone health, but it's not the primary factor for Type 2 Primary Osteoporosis. Ovarian dysfunction primarily relates to Type 1 Osteoporosis, which is more associated with post-menopausal women rather than aging in both sexes. While excessive physical activity can affect bone health, it is generally not a causative factor of Type 2 Osteoporosis and can actually promote stronger bone density when done appropriately.
