Caution With Calcium for Kidney Patients
People with kidney disease may take calcium-based medication to lower their phosphorus levels, but doing so can be dangerous. Researchers analyzed data from 11 studies on more than 4,600 people with kidney disease and determined their risk of death. Those who took calcium-rich medication were 22 percent more likely to die than peers who used non-calcium treatments. Participants on calcium-based medication also had greater hardening of the arteries, which the researchers say may be one cause of their increased risk of death. The researchers say the findings are significant enough to warrant the use of non-calcium-based medications, even though calcium-based drugs are inexpensive. If you are taking a calcium-based medication, discuss the pros and cons with your doctor.
