When bad breath originates from the stomach, it is often linked to digestive issues such as excess stomach acid or acid reflux.
One of the most common causes is gastroesophageal reflux disease (GERD), where stomach acid flows back into the esophagus, leading to a foul taste and odor in the mouth. Another potential cause is infection with
Helicobacter pylori, a bacterium that causes gastritis and stomach ulcers and can also contribute to halitosis.
Irregular eating habits and skipping meals can worsen these symptoms, as they stimulate increased acid production, which may intensify bad breath. Eating at regular intervals and choosing foods wisely - avoiding acidic or fatty meals, alcohol, and caffeine - can help reduce stomach-related halitosis.
People facing this type of issue should consider seeing a gastroenterologist for evaluation and treatment of possible underlying stomach conditions, which can greatly improve symptoms of bad breath.
Additionally, not drinking enough water can lead to reduced saliva production. Since saliva naturally cleans and refreshes the mouth, a lack of it may result in halitosis. Aim to drink at least 2 liters of fluids daily to support oral freshness and hydration.
