Osteoporosis is a bone disease. Its name comes from Latin for “porous bones.”
The inside of a healthy bone has small spaces, like a honeycomb. Osteoporosis increases the size of these spaces, causing the bone to lose strength and density. In addition, the outside of the bone grows weaker and thinner.
Osteoporosis can occur in people of any age, but it’s more common in older adults, especially women. More than 53 million people in the United States either have osteoporosis or are at high risk of developing it.
People with osteoporosis are at a high risk of fractures, or bone breaks, while doing routine activities such as standing or walking. The most commonly affected bones are the ribs, hips, and the bones in the wrists and spine.
