What Causes Acid Reflux?
Acid reflux occurs when stomach acid flows backward into the oesophagus, the tube connecting your mouth to your stomach. The primary cause involves the lower oesophageal sphincter (LES), a ring of muscle that normally acts as a valve between the oesophagus and stomach. When this muscle weakens or relaxes inappropriately, stomach contents can escape upward, causing the burning sensation known as heartburn.
Several factors can contribute to LES dysfunction. Certain foods like chocolate, caffeine, citrus fruits, and spicy dishes can trigger acid production or relax the sphincter muscle. Lifestyle factors including smoking, excessive alcohol consumption, and eating large meals close to bedtime also increase the risk of acid reflux episodes.
Medical Conditions That Worsen Acid Reflux
Hiatus hernia represents a common anatomical cause of acid reflux. This condition occurs when part of the stomach pushes through the diaphragm into the chest cavity, disrupting the normal function of the LES. Obesity also increases pressure on the stomach, potentially forcing acid upward into the oesophagus.
Pregnancy can temporarily worsen acid reflux due to hormonal changes and increased abdominal pressure from the growing baby. Certain medications, including some painkillers, blood pressure medications, and sedatives, may also contribute to acid reflux symptoms by affecting the LES function.
Effective Treatment Options for Acid Reflux
Treatment for acid reflux typically begins with lifestyle modifications. These include eating smaller, more frequent meals, avoiding trigger foods, maintaining a healthy weight, and elevating the head of your bed. However, when lifestyle changes prove insufficient, medications can provide effective relief.
Proton pump inhibitors (PPIs) represent the most effective medication class for treating acid reflux. EverydayMeds offers several PPI options, with omeprazole 20mg capsules being the most commonly prescribed treatment. Omeprazole works by blocking the enzyme responsible for acid production in the stomach, significantly reducing the amount of acid available to cause reflux symptoms.
How Proton Pump Inhibitors Work
PPIs like omeprazole target the hydrogen-potassium pump in stomach cells, effectively shutting down acid production for up to 24 hours with a single dose. This mechanism differs from antacids, which only neutralise existing acid, or H2 blockers like famotidine, which partially reduce acid production.
EverydayMeds provides various PPI options including omeprazole, lansoprazole 15mg capsules, pantoprazole 20mg tablets, and esomeprazole tablets. The branded version Losec MUPS 20mg offers the same active ingredient as omeprazole in a different formulation that may suit some patients better.
Choosing the Right Treatment Approach
Most patients with mild to moderate acid reflux symptoms respond well to once-daily PPI therapy. Treatment typically begins with a standard dose, such as omeprazole 20mg taken in the morning before breakfast. Symptoms usually improve within 2-4 days, with maximum benefits achieved after 4-8 weeks of consistent use.
For patients who cannot tolerate PPIs or prefer alternative options, EverydayMeds also offers famotidine tablets, an H2 receptor antagonist that reduces acid production through a different mechanism. This medication may be suitable for those experiencing side effects from PPIs or requiring only mild acid suppression.
The duration of treatment varies depending on symptom severity and underlying causes. Some patients require only short-term therapy during symptom flares, while others with gastro-oesophageal reflux disease (GORD) may benefit from long-term maintenance therapy to prevent complications and maintain symptom control.
