Osteoporosis as a Multi-System Aging Disease
Osteoporosis is a skeletal disease characterized by diminished bone mass and
microarchitectural deterioration, which renders the skeleton friable and predisposes a person to
fracture (Smit et al., 2024). It is a substantial public health issue in all aging populations, with
millions of older adults worldwide affected. With more and more people living longer, the
number of people who have osteoporosis is growing, and those with osteoporosis have less
mobility, chronic pain, and a greater risk of disability.
Although osteoporosis is well known as a problem of the skeleton system, it is affected
by aging-related changes in other body systems. Hormonal shifts — especially the dropping of
estrogen and testosterone—associated with aging- help speed bone loss (Chandra & Rajawat,
2021). Like the decline in digestive efficiency related to aging, calcium and D are also returned,
not to mention vitamin D, absorption, and the integumentary system’s decreasing ability to make
the vitamin all compound bone decline.
Developing effective interventions requires understanding osteoporosis's contribution as
a multi-system aging disease. The paper will be the suggestion of a therapeutic approach that
combines weight-bearing exercise and targeted supplementation to mitigate bone loss and
enhance overall skeletal health.
Background on the Skeletal System and Bone Aging
The skeletal system supports the body structure and helps the body move, and it also acts
as the mineral reservoir containing essential minerals such as calcium and phosphorus. Bone is a
dynamic tissue where changes occur constantly and is controlled by the balance between bone-
resorbing osteoclasts and builder osteoblasts (Chandra & Rajawat, 2021). This balance is
essential to ensure the bones stay intense and density high.
Remodeling the bone becomes less and less efficient as people age. The osteoblast
activity diminishes, and osteoclast bone resorption becomes severed, causing bone mass loss. It
also contributes to weakening the skeletal structure; bones become more fragile and subject to
fracturing, most notably in weight-bearing areas such as the hip or spine (Smit et al., 2024).
Other causes are aging-related, such as hormonal shifts and decreased nutrient absorption,
promoting bone loss. Calcium and vitamin D intake are crucial for too much mineralization and,
among other things, stimulate bone formation and reduce the risk of osteoporosis. It is necessary
to develop effective osteoporosis prevention and treatment strategies by knowing these changes
with age in bone physiology.
The Multi-System Contributions to Osteoporosis
Endocrine System: Hormonal Changes and Bone Loss
Antibody regulation is crucial to achieving and maintaining bone density; estrogen and
testosterone inhibit bone resorption. Specifically, estrogen suppresses osteoclast activity, and
testosterone increases bone formation (Alabadi et al., 2024). As people get older, hormone levels
start to drop, especially during menopause, and there is faster bone loss and an increased risk of
fracture.
In addition to sex hormones, the parathyroid hormone (PTH) and cortisol influence bone
metabolism. PTH stimulates bone resorption when calcium is low to maintain calcium
homeostasis. With age-related calcium deficiencies comes chronic elevation of PTH, which,
when excessive, can result in too much bone loss.
Digestive System: Nutrient Absorption and Bone Health
Bone health relies on the digestive system, allowing absorption of calcium and vitamin
D. Unfortunately, such inactivity negatively correlates with gastric acid production, making it
3
more difficult for calcium to dissolve and absorb. Furthermore, the change in the gut microbiome
can further disrupt nutrient uptake (Fuentes, 2022). Osteoporosis is made worse by certain
digestive disorders, such as celiac disease and Crohn’s disease, which contribute to chronic
calcium and vitamin D malabsorption; because they cause poor mineralization of bone, they
render the bone weak and susceptible to fractures.
Integumentary System: Vitamin D Synthesis and Aging
Vitamin D synthesis depends on the skin and the integumentary system as a whole, but
mainly on the skin. However, the skin cannot then make vitamin D, and aging reduces the skin’s
ability to do this, meaning there are widespread deficiencies in older adults. Since vitamin D is
necessary for calcium absorption, its decline will result in poor bone mineralization and a higher
fracture risk (Alabadi et al., 2024). Additional limits to vitamin D production include reduced
outdoor activity and the use of sunscreen.
Feasible Therapeutic Intervention: Exercise and Supplementation
Exercise as an Intervention
Weight-bearing and resistance exercises are among the best nonpharmacological
strategies to preserve bone density and prevent osteoporosis. Weight-bearing exercises, including
walking, jogging, and dancing, make the bones bear weight and push the osteoblast activity and
shrinking bones. Mechanical stress, applied (increasing) by resistance training, including lifting
weights or resistance bands, further strengthens bone through bone formation and density
improvement.
Research has supported exercise as part of the prevention and management of
osteoporosis. Consistent weight-bearing and resistance training studies have also demonstrated
that with prospective older adults, they increase bone mineral density (BMD), reduce fracture
risk, and improve overall musculoskeletal function (Fuentes, 2022). Exercise also improves
balance and coordination, decreasing the risk of falls and leading causes of fractures in people
with osteoporosis.
Calcium and Vitamin D Supplementation
Bones require calcium and vitamin D for proper remodeling and bone fracture
prevention. Bones are the structural component of calcium, while vitamins are the component
that absorbs calcium in the intestines (Ye et al., 2022). As the body does not get sufficient intake,
it will withdraw from the bones and begin destroying the structure over time.
The recommended daily calcium intake for older adults is 1,000–1,200 mg, and vitamin
D is 600–800 IU, depending on age and individual risk factors (Ye et al., 2022). These are
dietary sources found in dairy products, leafy greens, and fortified foods, but supplementation
may be needed for people depleted.
The risks of excessive calcium supplementation include kidney stones and vascular
calcification. Proper vitamin D supplementation should be targeted according to the individual
needs and accordingly optimized vitamin D intake for efficient calcium absorption (Fuentes,
2022).
Experimental Design to Test the Intervention
A randomized control trial (RCT) with three groups will be used for the experimental
design: an exercise (weight-bearing and resistance training) group, a supplementation group
(calcium and vitamin D) group, and a third group that receives both. Through dual-energy X-ray
absorptiometry (DEXA) scans for bone mineral density (BMD), blood tests for absorption of
nutrients calcium and vitamin D, and blood markers for vitamin D synthesis, the primary
variables to be measured will include hormonal levels (estrogen, parathyroid hormone).

Statistical analysis of pre-and post-intervention measurements will assess how all groups have
improved effectiveness.
Conclusion
Osteoporosis is a multi-system aging disease that includes skeletal, endocrine, digestive,
and integumentary systems. Hormonal changes, nutrient absorption, and vitamin D synthesis are
crucial in bone health. However, the proposed intervention, involving exercise and
supplementation, effectively dealt with these systems. Future research should focus on the long-
term effects of combined interventions and optimize the strategies according to personal needs
and variations in age, health status, and lifestyle.
