Final answer:
Osteoporosis is a condition characterized by a decrease in bone mass and an imbalance between bone resorption and bone formation. One of the main causes is an imbalance where bone resorption out-paces bone deposit. Other factors such as poor diet and lack of exercise can also contribute to osteoporosis.
Step-by-step explanation:
Osteoporosis is a condition where there is a decrease in bone mass and an imbalance between bone resorption and bone formation. One of the main causes of osteoporosis is when bone resorption out-paces bone deposit, meaning that more bone is being broken down than is being rebuilt. Other factors that can contribute to osteoporosis include genetic and environmental factors, such as poor diet, smoking, alcohol consumption, lack of exercise, and vitamin D deficiency.
