Daily Belching: Causes and Further Testing Options - Gastroenterology and Hepatology

Daily belching can be a frustrating and uncomfortable issue, especially when it persists despite treatment. Your situation, which began in July of last year, involves frequent belching and has been associated with findings of excess stomach acid and bile reflux from your endoscopies. You have been prescribed medications such as pantoprazole (often referred to as "耐恩適") and other gastric medications, but the relief has been limited.
Belching, or the act of expelling air from the stomach through the mouth, can be caused by various factors. In your case, the diagnosis of increased gastric acid and bile reflux suggests that your gastrointestinal (GI) tract may be sensitive or reactive. The mention of "gastric autonomic nervous sensitivity" by your doctor indicates that your stomach may be responding excessively to stimuli, which can lead to increased air swallowing or gas production.

Here are some potential causes of your daily belching:
1. Aerophagia: This is the act of swallowing air, which can happen unconsciously while eating, drinking, or even talking. Stress and anxiety can exacerbate this condition, leading to increased air swallowing.

2. Dietary Factors: Certain foods and beverages can contribute to gas production. Carbonated drinks, high-fiber foods, and certain sugars (like lactose or fructose) can lead to increased belching. Keeping a food diary may help identify any dietary triggers.

3. Gastroesophageal Reflux Disease (GERD): This condition can cause symptoms like belching, heartburn, and regurgitation. If you have been diagnosed with bile reflux, it may be worth discussing whether GERD is also a factor.

4. Functional Dyspepsia: This is a common disorder characterized by chronic or recurrent pain in the upper abdomen, which can include symptoms like belching, bloating, and nausea. It may not have a clear organic cause, but it can be distressing.

5. H. pylori Infection: This bacterial infection can lead to gastritis and peptic ulcers, which may contribute to symptoms like belching. Testing for H. pylori may be worthwhile if it hasn't been done already.

6. Other Gastrointestinal Disorders: Conditions such as irritable bowel syndrome (IBS) or gastroparesis can also lead to increased gas and belching. If your symptoms include changes in bowel habits or abdominal pain, further evaluation may be necessary.

Given that your symptoms have persisted despite medication, it may be beneficial to consider further testing. Here are some options:
- Hydrogen Breath Test: This test can help diagnose conditions like lactose intolerance or small intestinal bacterial overgrowth (SIBO), both of which can lead to increased gas production.

- Upper GI Series: This imaging test can provide a view of your esophagus, stomach, and the first part of your small intestine to identify any structural abnormalities.

- Esophageal Manometry: This test measures the rhythmic muscle contractions in your esophagus when you swallow and can help assess esophageal motility issues.

- Gastric Emptying Study: If you suspect gastroparesis, this test can evaluate how quickly food leaves your stomach.

- Consultation with a Gastroenterologist: If you haven't already, seeking a second opinion from a gastroenterologist may provide additional insights or alternative treatment options.

In conclusion, while your current diagnosis of gastric autonomic nervous sensitivity is valid, it is essential to explore other potential causes and consider further testing to ensure that no underlying conditions are contributing to your symptoms. Keeping a detailed record of your symptoms, dietary habits, and any other relevant factors can be helpful for your healthcare provider in determining the best course of action.
