3Gastroesophageal Reflux Disease (GERD)
GERD can be the source of breath that smells like poop. Acid from your stomach is called up into your esophagus and mouth, hence irritating the esophageal lining. Many people with gastroesophageal reflux disease aren’t aware of it. If you have gastroesophageal reflux disease, you might experience symptoms like mild or severe reflux (perhaps twice a week), regurgitating acidic or sour fluid, and difficulty swallowing.
