Question

Osteoporosis is caused by

• A. Fe${}^{2+}$ defeciency
• B. Na${}^{+}$ deficiency
• C. Parathormone hyposecretion
• D. Parathormone hypersecretion

Answer 1

The correct option is D Parathormone hypersecretion

Osteoporosis is a condition in which bone density decreases and bones become weak and brittle. It occurs due to hypersecretion of parathormone. Parathormone is secreted from the parathyroid hormone and increases blood calcium level by increasing the reabsorption of calcium from the bones. Over secretion of parathormone causes more calcium dissolution from the bones leading to decreased bone density.

So, the correct answer is 'Parathormone hypersecretion'.
