Response of Gastrointestinal Hormones and Intestinal Calcium Absorption During an Oral Carbohydrate Meal
Little is known about changes of gastrointestinal (GI) hormones in patients with calcium lithiasis. In a preliminary study1 we reported altered responses of GI hormones to a test meal in not rigidly classified calcium stone patients. It might be possible, that these observed changes modify the intestinal calcium absorption (CaA), which is one main cause for hypercalciuria in calcium stone formers. Therefore, we studied the influence of a synthetic test meal on the CaA and the secretion of gastrin, insulin, C-peptide, glucagon and glucose in healthy volunteers and patients with recurrent calcium lithiasis.
