Osteoporosis is a condition that makes bones weak and brittle. In severe cases, it is indeed possible to suffer fractures from mild actions like coughing. Osteoporosis is more common in older adults, especially women, as bone density decreases with age. To prevent and manage osteoporosis, it's important to get enough calcium and vitamin D, exercise regularly, and avoid smoking and excessive drinking. If you're at risk for osteoporosis, it's best to consult a doctor for evaluation and treatment.
