Osteoporosis is seen in all the following except –
**Core Concept**
Osteoporosis is a chronic bone disorder characterized by decreased bone mass and density, leading to increased risk of fractures. It results from an imbalance between bone resorption and bone formation, often due to hormonal, nutritional, or genetic factors.
**Why the Correct Answer is Right**
The correct option is not provided, so we will analyze the typical conditions associated with osteoporosis. Osteoporosis is commonly seen in conditions that involve excessive bone resorption, such as hyperparathyroidism, where an overactive parathyroid gland releases excessive parathyroid hormone (PTH), leading to increased osteoclast activity and bone breakdown. Other conditions like postmenopausal osteoporosis are also associated with decreased estrogen levels, which can accelerate bone resorption.
**Why Each Wrong Option is Incorrect**
**Option A:** Hyperparathyroidism is a known cause of osteoporosis due to excessive PTH release. Incorrect option.
**Option B:** Postmenopausal osteoporosis is a common condition where decreased estrogen levels lead to increased bone resorption. Incorrect option.
**Option C:** Steroid-induced osteoporosis occurs due to glucocorticoid-induced suppression of bone formation and increased bone resorption. Incorrect option.
**Clinical Pearl / High-Yield Fact**
To remember the causes of osteoporosis, recall that "HARM" stands for the conditions that can lead to osteoporosis: Hyperparathyroidism, Aging (postmenopausal), Rheumatoid arthritis, and Malnutrition.
**Correct Answer: None. Osteoporosis is seen in all the provided options.
