<P> In hypochlorhydria and achlorhydria, there is low or no gastric acid in the stomach, potentially leading to problems as the disinfectant properties of the gastric lumen are decreased . In such conditions, there is greater risk of infections of the digestive tract (such as infection with Vibrio or Helicobacter bacteria). </P> <P> In Zollinger--Ellison syndrome and hypercalcemia, there are increased gastrin levels, leading to excess gastric acid production, which can cause gastric ulcers . </P> <P> In diseases featuring excess vomiting, patients develop hypochloremic metabolic alkalosis (decreased blood acidity by H and chlorine depletion). </P> <P> The proton pump enzyme is the target of proton pump inhibitors, used to increase gastric pH (and hence decrease stomach acidity) in diseases that feature excess acid . H antagonists indirectly decrease gastric acid production . Antacids neutralize existing acid . </P>
