Secondary osteoporosis is a bone disease caused by other health conditions, medications, and lifestyle factors. Osteoporosis is a condition that makes bones weak and brittle. We often think of bones as solid, but they actually have small, honeycomb-like spaces inside. In people with osteoporosis, these spaces become larger, reducing bone strength and density. Secondary osteoporosis is usually due to health issues such as cancer and endocrine disorders. For most people, a fracture is the first sign or symptom of osteoporosis because the loss of bone mass and strength tends to happen gradually. Fractures most commonly occur in the spine, hips, and wrists. The primary method to diagnose osteoporosis is a bone density test, but doctors may also perform blood tests to check hormone levels and other indicators. Treatment first addresses any reversible health issues and typically includes medications and lifestyle changes. The most common medications are bisphosphonates. Additionally, lifestyle changes such as increasing calcium and vitamin D intake and engaging in appropriate exercise are crucial.
