Effect of a mineral water on gastric emptying of patients with idiopathic dyspepsia.

The antidyspeptic property of mineral waters has for many years been based on empirical data. In the present paper we evaluated the effects of one type of mineral water, Tettuccio water from Montecatini, on gastric emptying in patients with idiopathic dyspepsia. Fourteen subjects, eight patients with idiopathic dyspepsia and delayed gastric emptying at scintigraphy and six healthy subjects with normal gastric emptying were studied. The gastric emptying of mineral water was studied with a scintigraphic method and compared with that of tap water. In patients with idiopathic dyspepsia, gastric emptying of both waters was slower than in controls but the gastric emptying of mineral water was significantly faster than that of tap water, both in dyspeptic patients and in healthy subjects. In conclusion, this mineral water stimulates gastric emptying. Further studies are needed on the possible role of this water in the management of chronic idiopathic dyspepsia.
