Common Causes and Risk Factors for Acid Reflux
How Acid Reflux Develops
Acid reflux occurs when the lower oesophageal sphincter (LES), a ring of muscle between the stomach and oesophagus, becomes weakened or relaxes inappropriately. This allows stomach acid to escape upwards into the oesophagus, causing the burning sensation known as heartburn. The oesophagus lacks the protective lining found in the stomach, making it vulnerable to acid damage.
Dietary Triggers
Certain foods and drinks commonly trigger acid reflux symptoms. Spicy foods, tomatoes, citrus fruits, chocolate, caffeine, alcohol, and fatty or fried foods may increase acid production or relax the LES. Carbonated beverages can increase stomach pressure, whilst acidic foods may directly irritate the oesophageal lining. Individual triggers vary, so keeping a food diary may help identify personal problem foods.
Lifestyle Factors
Several lifestyle factors contribute to acid reflux development. Obesity increases abdominal pressure, pushing stomach contents upward. Smoking weakens the LES and reduces saliva production, which normally helps neutralise acid. Eating large meals stretches the stomach and increases pressure. Lying down soon after eating allows gravity to work against you, making reflux more likely. Tight clothing around the waist can also increase abdominal pressure.
Medical Conditions
Certain medical conditions increase acid reflux risk. Hiatus hernia occurs when part of the stomach pushes through the diaphragm, affecting the LES function. Pregnancy increases reflux risk due to hormonal changes and increased abdominal pressure from the growing baby. Gastroparesis, where stomach emptying is delayed, can lead to increased reflux. Some medications, including certain blood pressure drugs and anti-inflammatory medicines, may also contribute to symptoms.
Treatment Options Available
When acid reflux becomes frequent or severe, treatment may be necessary. Proton pump inhibitors (PPIs) like omeprazole 20mg capsules are commonly prescribed to reduce stomach acid production. EverydayMeds offers several acid reflux treatments, including omeprazole, lansoprazole, and pantoprazole tablets. These medications work by blocking the pumps that produce stomach acid, allowing the oesophagus to heal and preventing further damage. H2 blockers like famotidine provide an alternative approach by reducing acid production through a different mechanism.
