In the early years after the discovery of<unk> , the prevalence of the disease among people treated with Sippy's treatment varied from 2% to 18%. The wide range was attributed to the differing amounts of<unk>  absorbed among people. In the 1900s, the mortality rate of people with<unk>  was found to be 4.4%. The use of<unk>  and<unk>  to treat gastric ulcers greatly contributed to the development of<unk>  in people but the incidence of<unk>  greatly diminished when the true cause of most gastric ulcers was identified and drugs other than antacids were developed to treat heartburn, such as acid-reducing drugs like H2-receptor antagonists or proton pump inhibitors. These new drugs replaced Sippy's diet treatment for peptic ulcers. However, the incidence of<unk>  has increased again since the 1990s due to increased osteoporosis awareness and the preventative routine use of calcium supplements. The consumption of calcium supplementation in today's society that has aided in the resurgence of<unk>  has sparked conversation about changing the name of<unk>  to calcium<unk>  syndrome as it more accurately reflects the cause of this syndrome. Currently,<unk>  is the third most common cause of people hospitalized with high blood calcium, after hyperparathyroidism and cancer. In regards to populations at risk, there has been a shift in the condition's demographic over time. Previously,<unk>  was predominantly seen amongst males with ulcers. As new treatments for peptic ulcers arose, there was change in the causation of hypercalcemia. Presently, individuals who are at a higher risk of developing<unk>  are pregnant or postmenopausal individuals and the elderly.
