What Results When the Rate of Bone Loss Exceeds Bone

Question

What results when the rate of bone loss exceeds bone formation?  
A) Graves' disease
B) Osteoporosis
C) Hashimoto's disease
D) Osteoarthritis
E) Polio

Accepted Answer

Osteoporosis is a condition where there is a decrease in bone density due to an imbalance between bone resorption (loss) and bone formation. If the rate of bone loss exceeds bone formation, it can lead to osteoporosis. Graves' disease and Hashimoto's disease are autoimmune disorders that affect the thyroid gland. Osteoarthritis is a joint disease that results from the breakdown of joint cartilage and underlying bone. Polio is a viral infection that can lead to paralysis. None of these conditions are directly related to an imbalance between bone resorption and bone formation.
