Contrary to popular belief, the stomach does not play a major role in producing bad breath.
Bad breath is greatly misunderstood.
It is usually perceived as related to food, age, sex, habits, and medical and dental conditions. Contrary to popular belief, the stomach does not play a major role in producing bad breath. Bad breath arising from the stomach is very unlikely due to the physiological relationship of the pyloric valve between the esophagus and the stomach. Unless you have a hiatal hernia, esophagial reflux, or gastric ulcers, your stomach probably isn't producing your bad breath. Millions of Americans consider bad breath a major social concern , and are more willing to seek advice from their dentist than their physician.
