Of the following, which is an early sign (indication) that you may have osteoporosis?

The correct indication that you may have osteoporosis is the option mentioning that usually there are no signs. Osteoporosis is often referred to as a "silent disease" because many people may not experience noticeable symptoms in the early stages. This means they may not realize they have the condition until they suffer a fracture or bone injury.

Unexplained pain, weight loss, and frequent fractures are not typically acknowledged as early signs of osteoporosis. Instead, these could point to other health issues or occur as a result of advanced osteoporosis when the bones have already weakened significantly. The absence of early warning signs highlights the importance of preventive measures, such as regular bone density screenings, especially for individuals at higher risk for osteoporosis.
