What Causes Acid Reflux and How Can It Be Treated?
Understanding the Mechanism of Acid Reflux
Acid reflux occurs when stomach acid escapes into the oesophagus due to a weakened lower oesophageal sphincter (LES). This muscular ring normally acts as a barrier between the stomach and oesophagus. When it relaxes inappropriately or becomes weakened, acidic stomach contents can flow backward, causing the burning sensation known as heartburn.
Common Dietary Triggers
Certain foods and beverages are known to trigger acid reflux symptoms. Spicy foods, citrus fruits, tomatoes, chocolate, caffeine, and alcohol can all relax the LES or increase acid production. Fatty and fried foods delay gastric emptying, allowing more time for reflux to occur. Identifying and avoiding personal triggers is often the first step in managing symptoms.
Lifestyle Risk 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 or lying down shortly after eating can also trigger symptoms. Wearing tight clothing around the waist may increase abdominal pressure.
Medical Conditions Associated with Acid Reflux
Hiatus hernia is a common cause of acid reflux, where part of the stomach pushes through the diaphragm. Pregnancy often causes reflux due to hormonal changes and increased abdominal pressure from the growing baby. Other conditions including diabetes, scleroderma, and certain medications can affect gastric motility or LES function.
Comparing Esomeprazole vs Omeprazole for Treatment
Both esomeprazole and omeprazole belong to the proton pump inhibitor (PPI) class of medications, which work by blocking acid production in the stomach. Omeprazole, available as 20mg capsules, is typically the first-choice PPI due to its proven effectiveness and favourable side effect profile. Esomeprazole is the S-isomer of omeprazole and may provide slightly more consistent acid suppression in some patients. The choice between these medications often depends on individual response and tolerability.
Available Treatment Options
EverydayMeds offers several acid reflux treatments to suit different needs. Omeprazole 20mg capsules remain the most commonly prescribed PPI, whilst Losec MUPS provides a branded alternative. For patients requiring different PPI options, lansoprazole 15mg capsules and pantoprazole 20mg tablets are available. Famotidine tablets offer an H2 receptor antagonist alternative for those who cannot take PPIs.
When to Seek Professional Advice
Whilst occasional heartburn is common, persistent symptoms warrant medical evaluation. Warning signs include difficulty swallowing, unintentional weight loss, persistent vomiting, or chest pain. These may indicate complications such as oesophagitis, Barrett's oesophagus, or other serious conditions requiring specialist assessment and treatment.
