Causes of bad breath from the stomach

Below are common causes of bad breath from the stomach:

Bad breath due to gastroesophageal reflux disease (GERD)

When experiencing gastric reflux, stomach acid is pushed up into the esophagus, causing damage to the esophageal mucosa. This creates an environment for bacteria to thrive in the acidic environment, resulting in bad breath. You can identify bad breath from the stomach if you frequently experience sour or acid regurgitation.

Bad breath due to gastric ulcers caused by Helicobacter Pylori (HP) bacteria

Bad breath in cases of gastric ulcers is often attributed to the bacteria Helicobacter pylori (HP). HP bacteria usually reside beneath the gastric mucosa and cause gastric ulcers. When the stomach is inflamed due to HP bacteria, it produces gases such as dimethyl sulfide, sulfur, and methyl mercaptan, causing an unpleasant odor.

Bad breath due to gastric valve incompetence

In normal individuals, the gastric valve remains tightly closed and only opens during eating and drinking. However, when patients suffer from gastric valve incompetence, this valve remains open, causing the regurgitation of gastric fluids and food odor into the esophagus and throat, resulting in bad breath.

How to treat bad breath from stomach ?Treating bad breath from the stomach involves addressing the underlying stomach issues. For conditions such as stomach ulcers, gastric reflux, and a weakened lower esophageal sphincter, it is important to seek medical attention for diagnosis and treatment. Depending on the specific condition, a doctor may prescribe appropriate medications. Here are some commonly used medications for treating bad breath from the stomach:

  • Proton pump inhibitors: These medications reduce stomach acid levels by inhibiting the activity of acid-producing receptors in the gastric mucosa. Examples of medications in this group include Omeprazole, Lansoprazole, Esomeprazole, Pantoprazole, and Rabeprazole.
  • H2 histamine receptor antagonists: These medications inhibit histamine at the H2 receptors in the gastric lining, thereby reducing acid secretion and gastric fluid. Examples of H2 histamine receptor antagonists include Cimetidine, Ranitidine, Famotidine, and Nizatidine.
  • Antacid medications: These medications neutralize stomach acid and include absorbable antacids such as Sodium bicarbonate and Calcium carbonate, as well as non-absorbable antacids such as Aluminum or Magnesium hydroxide.
  • Prostaglandins: These medications inhibit acid secretion by reducing the formation of cyclic AMP and enhancing the protective ability of the gastric mucosa.
  • Sucralfate: This is a sucrose-aluminum complex that forms a protective layer in the inflamed areas of the stomach, protecting them from acid, pepsin, and bile salts.

Note: Before using any medication, it is important to consult with a doctor to avoid any potential side effects on your health.

Treating stomach-related bad breath with home remedies

For mild cases of bad breath from the stomach, there are some home remedies that can help improve the condition:

  • Using mint leaves: Mint leaves contain essential oils that can freshen breath. Simply chew a few fresh mint leaves and rinse your mouth to improve bad breath.
  • Using fresh lemon: Lemon contains vitamin C and citric acid, which have antibacterial properties and can effectively reduce bad breath. You can rinse your mouth with lemon juice or drink lemon water 4-5 times a week.
  • Chewing sugar-free gum: Chewing gum stimulates saliva production, helping to remove bacteria and excess food in the mouth.
