The following are risk factors for developing osteoporosis (Select all that apply) Multiple options may be correct

A. High caffeine intake: Excessive caffeine consumption can decrease calcium absorption in the intestines and increase calcium excretion through the kidneys. Over time, this contributes to reduced bone mineral density and increases the risk of osteoporosis, especially if calcium intake is inadequate. B. Skinny: Low body weight is a significant risk factor for osteoporosis because there is less mechanical stress on bones to stimulate bone formation. Additionally, individuals with low body fat may have reduced estrogen levels, which plays a protective role in maintaining bone density. C. Vitamin D deficiency: Vitamin D is essential for calcium absorption in the gastrointestinal tract. Deficiency leads to decreased calcium availability for bone mineralization, resulting in weakened bones and an increased risk of osteoporosis and fractures. D. Overweight: Higher body weight generally provides increased mechanical loading on bones, which can help maintain or even increase bone density. While obesity has other health risks, it is not typically associated with increased risk of osteoporosis. E. Menstruating: Regular menstruation indicates normal estrogen levels, which help protect bone mass. Estrogen plays a key role in inhibiting bone resorption, so individuals who are menstruating are at lower risk compared to those with amenorrhea or postmenopausal status.
