Gastroesophageal Reflux Cough (GERC) occurs when stomach acid flows back into the esophagus, leading to irritation and triggering coughing. This article aims to provide a comprehensive yet accessible overview of GERC, covering types, causes, symptoms, diagnostic tests, treatments, medications, and potential surgical options.

Types of Gastroesophageal Reflux Cough:

1. Acidic Reflux Cough: The most common type, characterized by stomach acid irritating the esophagus, leading to persistent coughing.
2. Non-Acidic Reflux Cough: Caused by non-acidic stomach contents irritating the esophagus, resulting in chronic coughing.

Causes of Gastroesophageal Reflux Cough:

1. Hiatal Hernia: A condition where part of the stomach protrudes into the diaphragm, increasing the risk of acid reflux.
2. Obesity: Excess weight can put pressure on the stomach, promoting acid reflux.
3. Smoking: Tobacco use weakens the lower esophageal sphincter, allowing stomach acid to flow back.
4. Pregnancy: Hormonal changes during pregnancy can lead to relaxation of the esophageal sphincter, causing reflux.
5. Certain Foods: Spicy, acidic, and fatty foods can trigger reflux.
6. Alcohol: Excessive alcohol consumption can relax the esophageal sphincter, promoting reflux.
7. Medications: Some drugs, like antihypertensives or sedatives, may contribute to GERC.
8. Delayed Stomach Emptying: Conditions that slow down stomach emptying can increase the risk of reflux.
9. Connective Tissue Disorders: Conditions affecting connective tissues may weaken the esophageal sphincter.
10. Asthma: GERC and asthma often coexist, and one can exacerbate the other.
11. Snacking Before Bed: Eating late at night can trigger reflux.
12. Tight Clothing: Wearing tight clothing around the abdomen can increase pressure on the stomach.
13. Lying Down After Meals: Immediate horizontal position after eating can facilitate reflux.
14. Carbonated Beverages: These can increase the pressure on the stomach, leading to reflux.
15. Caffeine: Found in coffee, tea, and chocolate, caffeine can relax the esophageal sphincter.
16. Peppermint: This herb may relax the muscles of the esophagus.
17. Overeating: Large meals can overwhelm the stomach, causing reflux.
18. Spicy Foods: These can irritate the esophagus, triggering cough.
19. Citrus Fruits: Oranges, lemons, and tomatoes can increase acid production.
20. Certain Postures: Bending over or lying down after eating may contribute to reflux.
