Researchers determined that bad breath may also relate to certain ulcers caused by bacteria, such as Helicobacter pylori, informs Colgate. Treating the ulcer with antibiotics effectively eliminates the issue of bad breath. Bad breath as a result of stomach issues is not a common occurrence amongst the general population.

Acid reflux occurs when undigested food, bile and stomach acids flow backwards out of the stomach and into the esophagus, usually as a result of a weak or malfunctioning lower esophageal sphincter, according to Healthline. This not only results in bad breath but a sour or bitter taste in the mouth. Treating the acid reflux also helps eliminate the bad breath it causes. Treating acid reflux requires eliminating certain foods from the diet, such as coffee, alcohol, citrus fruits, tomato products and garlic. Increasing ingestion of fiber-rich foods, beans, whole grains and vegetables may also help eliminate bad breath as a result of acid reflux. Histamine blockers, proton pump inhibitors and antacids are also common medicines that treat acid reflux.
