Osteoporosis is more likely to occur in the following groups: firstly, the elderly, as bone density naturally decreases with age. Secondly, women, especially postmenopausal women, because their estrogen levels drop, accelerating bone loss. Additionally, people with a family history of osteoporosis, those who are underweight, those with diets low in calcium and vitamin D, those who lack physical activity, and those who smoke or drink heavily are also more susceptible to developing osteoporosis.
