In boys, the process occurs about a year or two later, so the most important period is about 12 to 16 years. The first descriptions of bone problems in people with CF were usually related to bone fractures that occurred after lung transplantation in patients with severe lung disease and other symptoms. These patients had low bone mineral content and low bone density. The physical rehabilitation and medications required after transplantation caused bone fractures in some patients. Since then, we have learned that many people, from children to adults, with mild to severe lung disease, also have low bone mineral density and are at risk for fracture.
Dietary calcium is important for all people to develop strong, healthy bones.
Most calcium comes from dairy products, so the intake of milk, cheese, yogurt, and other dairy products are important to ensure enough calcium is included in the diet. We know that people who take in higher levels of calcium over their lifetime generally have stronger bones and less osteoporosis and bone fractures. Likewise, people who have a diet deficient in calcium are more likely to develop osteoporosis. A healthy diet now can prevent osteoporosis later. Additional sources of calcium, such as Tums , are fairly well absorbed, and are commonly used for supplements to increase the calcium intake.
