It is important for the skeletal system to maintain homeostasis so that the system does not weaken and deteriorate, causing other systems to weaken or fail. The skeletal system maintains homeostasis by ensuring that calcium levels in the bones are where they should be to be considered healthy. If the balance is disrupted, there are risks of bone deterioration and injuries such as fractures or calcium deficiency. If this happens, different treatments may be given. The first is physiotherapy such as exercise to strengthen bones. Another form of treatment involves taking medications such as vitamin D supplements or hormones such as parathyroid hormone (PTH) to help the extracellular fluid stay balanced. “Drugs that are easy to apply and have a low frequency of administration are associated with greater compliance. Increasing medication adherence in real-world medicine is an important clinical goal, especially in the treatment of osteoporosis” (Tomková, Telepková, Vaňuga, Killinger, Šulková, Celec & Payer, 2014). It is very important to maintain calcium intake at the recommended level in order to maintain a balance. “Calcium in the diet is necessary to maintain bone density. Its absorption is affected by vitamin D, phytates present in the diet, as well as other nutrients (phosphorus, sodium and protein). Dietary interventions primarily focus on increasing dietary calcium”
