Primary Causes and Risk Factors for Acid Reflux
How the Lower Oesophageal Sphincter Works
The lower oesophageal sphincter (LOS) acts as a valve between your oesophagus and stomach. When functioning properly, it opens to allow food into the stomach and closes to prevent acid from flowing back up. Acid reflux occurs when this muscle weakens or relaxes inappropriately, allowing stomach acid to escape into the oesophagus. This can happen due to various factors including certain foods, medications, or underlying medical conditions.
Common Dietary Triggers
Certain foods and beverages are known to trigger acid reflux symptoms by either relaxing the LOS or increasing stomach acid production. Common culprits include spicy foods, tomatoes and citrus fruits, chocolate, mint, coffee, and alcohol. Fatty or fried foods can slow digestion and increase pressure on the LOS. Carbonated beverages may cause bloating and pressure that forces acid upward. Identifying and avoiding your personal triggers can significantly reduce symptom frequency.
Lifestyle and Behavioural Factors
Several lifestyle choices can contribute to acid reflux development. Obesity increases abdominal pressure, pushing stomach contents upward. Smoking weakens the LOS and reduces saliva production, which normally helps neutralise acid. Eating large meals or lying down shortly after eating can trigger symptoms. Tight clothing around the waist may increase pressure on the stomach. Stress doesn't directly cause acid reflux but can worsen symptoms by affecting digestion and increasing acid production.
Medical Conditions and Medications
Certain medical conditions increase acid reflux risk. Hiatal hernia occurs when part of the stomach pushes through the diaphragm, affecting LOS function. Gastroparesis slows stomach emptying, increasing pressure and reflux risk. Pregnancy can cause reflux due to hormonal changes and increased abdominal pressure. Some medications including NSAIDs, certain antibiotics, and calcium channel blockers may worsen symptoms by relaxing the LOS or irritating the oesophageal lining.
When to Seek Treatment
While occasional heartburn is normal, frequent acid reflux may indicate gastro-oesophageal reflux disease (GORD) requiring medical treatment. Symptoms occurring more than twice weekly or interfering with daily activities warrant professional evaluation. EverydayMeds offers effective prescription treatments including omeprazole 20mg capsules, the most commonly prescribed proton pump inhibitor. Alternative options include lansoprazole, pantoprazole, and esomeprazole tablets. For those requiring different mechanisms, famotidine tablets provide H2 blocker therapy. These medications work by reducing stomach acid production, allowing the oesophagus to heal and preventing further damage.
