Carbonated beverages induced hypercalciuria in young males.
J Liaquat Uni Med Health Sci Jan ;5(1):14-7.

OBJECTIVE: To assess the short-term effects of carbonated beverages on urinary calcium exertion in normal young males. SETTING: Department of Biochemistry, Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre, Karachi, from July 2003 to June 2004. METHOD: Twenty-five normal male subjects of 20-40 years age and habitual users of carbonated beverages were selected for the study. Their fasting and post-beverage urine samples were collected and analyzed for calcium excretion levels. RESULTS: Significant increase in urinary calcium levels was observed in subjects consuming both caffeinated (P<0.001) and non-caffeinated (P<0.01) beverages. CONCLUSION: The excess calciuria is confined to males who are habitual consumers of both caffeinated and non-caffeinated beverages. It is suggested that habitual use of beverages must be discouraged in order to prevent bone resorption and hence, an early osteoporosis.
