Common Causes and Risk Factors for Acid Reflux
How Acid Reflux Develops
Acid reflux occurs when stomach acid escapes upward into the oesophagus, causing irritation and discomfort. The lower oesophageal sphincter (LES), a ring of muscle that acts as a valve between the stomach and oesophagus, normally prevents this backflow. When the LES weakens or relaxes inappropriately, stomach contents can reflux upward, leading to the burning sensation known as heartburn.
Dietary Triggers and Eating Habits
Certain foods are well-known triggers for acid reflux symptoms. Spicy foods, citrus fruits, tomatoes, chocolate, caffeine, and fatty meals can all stimulate acid production or relax the LES. Carbonated drinks may increase pressure in the stomach, whilst alcohol can irritate the oesophageal lining and affect LES function. Large meals eaten quickly or lying down shortly after eating can also contribute to reflux episodes.
Lifestyle and Physical Factors
Excess weight, particularly around the abdomen, increases pressure on the stomach and can push acid upward. Smoking weakens the LES and increases acid production, whilst tight-fitting clothing around the waist may compress the stomach. Sleep position matters too - lying flat can make it easier for acid to travel up the oesophagus.
Medical Conditions and Medications
Hiatus hernia, where part of the stomach protrudes through the diaphragm, is commonly associated with acid reflux. Pregnancy increases reflux risk due to hormonal changes and pressure from the growing baby. Certain medications, including some painkillers, blood pressure medications, and sedatives, may contribute to symptoms by affecting LES function or increasing stomach acid production.
When to Consider Medical Treatment
If lifestyle modifications don't provide adequate relief, medical treatments may be beneficial. Proton pump inhibitors like omeprazole work by reducing stomach acid production at the source. EverydayMeds offers several effective options including omeprazole 20mg capsules, which are among the most commonly prescribed acid reflux treatments. Alternative PPIs such as lansoprazole, pantoprazole, and esomeprazole may be suitable for those who don't respond well to omeprazole. For some patients, H2 blockers like famotidine provide an alternative approach to reducing acid production.
