MCQ 32 All of the following can cause osteoporosis, except:

A.Hyperparathyroidism
B.Steroid use
C.Fluorosis
D.Thyrotoxicosis

The correct answer is C.Fluorosis


Note: Osteoporosis is defined as ‘a disease characterized by low bone mass and micro-architectural deterioration of bone tissue, leading to enhanced bone fragility and an increase in fracture risk’.

Osteoporosis results from increased bone breakdown by osteoclasts and decreased bone formation by osteoblasts leading to loss of bone mass.

• Hyperparathyroidism leads to increased bone resorption so leading to the osteoporosis. 
• Glucocorticoids are a common cause of medication-induced osteoporosis.
• Excessive thyroid hormone can accelerate bone remodeling and result in bone loss and leads to osteoporosis.
• Fluorosis leads to increased bone density so how it can lead to the osteoporosis.
