What is health effects can result from abnormal values of pH in stomach?
Gastric acid which is produced in the stomach gets neutralised
by the food we eat and by the bile and the pancreatic juices. High
levels of acidity can give rise to reflux oesophagitis, gastritis,
gastric erosion, gastric and duodenal ulcers and this can lead to
perforation and bleeding if the ulcers are not treated.
Low acidity for prolonged periods can be a cause for stomach
cancer.
