Acid Reflux and Heartburn: Causes, Symptoms, and Treatments
What Are Acid Reflux and Heartburn?
Acid reflux occurs when stomach acid flows back into the oesophagus, causing discomfort and a burning sensation in the chest or throat. If the condition becomes severe or frequent, it is known as gastro-oesophageal reflux disease (GORD).
Heartburn is a symptom of acid reflux, presenting as a burning or tightening sensation in the chest, typically just behind the breastbone. While the name might suggest otherwise, heartburn is unrelated to the heart and occurs within the digestive system.
Occasional heartburn is common and usually harmless. However, persistent symptoms may signal a more serious condition requiring medical attention.
What Causes Acid Reflux and Heartburn?
Acid reflux is triggered when the lower oesophageal sphincter (a muscle at the bottom of the oesophagus) weakens or relaxes improperly. This allows stomach acid to travel up the oesophagus, leading to irritation and discomfort.
Key Risk Factors Include:
- Consuming trigger foods such as coffee, alcohol, onions, citrus, tomatoes, and spicy or fatty dishes.
- Smoking and excessive alcohol consumption.
- Being overweight or pregnant.
- Stress, anxiety, and certain medications like anti-inflammatories.
- Medical conditions such as hiatus hernia.
Pregnant women and young children are particularly prone to acid reflux due to physiological factors such as hormonal changes and smaller stomach capacities.
Symptoms of Acid Reflux and Heartburn
Common Symptoms Include:
- Burning sensation in the chest or throat.
- Sour or bitter taste in the mouth.
- Persistent cough or hiccups.
- Hoarseness or sore throat.
- Bloated stomach or nausea.
Severe or Chronic Symptoms May Include:
- Difficulty swallowing or oesophageal spasms.
- Regurgitation of food or stomach contents.
- Tooth enamel damage due to acid exposure.
- Increased risk of oesophagitis, ulcers, or oesophageal cancer.
Symptoms often worsen after meals, when lying down, or during the night.
How to Manage and Treat Acid Reflux and Heartburn
Lifestyle Changes
- Eat smaller, more frequent meals.
- Avoid lying down immediately after eating.
- Elevate the head of your bed or use extra pillows while sleeping.
- Avoid tight clothing around the waist.
- Reduce consumption of trigger foods and beverages.
- Quit smoking and manage stress levels effectively.
Over-the-Counter Remedies
- Antacids: Provide quick relief by neutralising stomach acid.
- H2 Receptor Antagonists (H2RAs): Reduce stomach acid production for prolonged relief.
- Proton Pump Inhibitors (PPIs): Help heal the oesophagus and reduce acid production over a longer duration.
When to Consult a Healthcare Professionals
Seek medical advice if symptoms persist despite lifestyle changes and over-the-counter treatments. Symptoms such as unexplained weight loss, frequent nausea, or chest pain lasting more than three weeks may indicate an underlying condition requiring further investigation.
Available Acid Reflux Treatments
Proton pump inhibitors are commonly prescribed for managing chronic acid reflux. Popular options include:
- Esomeprazole
- Lansoprazole
- Omeprazole
- Pantoprazole
- Rabeprazole
These medications are available online through secure consultations with healthcare providers.
FAQs About Acid Reflux and Heartburn

No. Acid reflux is the condition, while heartburn is a symptom of it.
What Foods Should I Avoid with Acid Reflux?
Avoid acidic, fatty, and spicy foods and beverages like coffee, alcohol, and carbonated drinks.
Can Heartburn Lead to Complications?
Yes, if untreated, chronic heartburn (GORD) can damage the oesophagus and increase the risk of serious conditions.
