Acid Reflux

Acid Reflux


Acid reflux is a common digestive condition that affects millions of people across the UK, causing discomfort that can disrupt daily life. It occurs when stomach acid travels back up into the oesophagus, leading to symptoms such as heartburn, an unpleasant bitter taste, and a burning sensation in the chest. Whether you experience occasional flare-ups after meals or more frequent episodes, a range of effective over-the-counter and prescription treatments are available to help manage your symptoms. From fast-acting antacids to longer-term acid suppressants, finding the right solution can make a significant difference to your comfort and wellbeing.

What Is Acid Reflux?

Acid reflux, also known as gastro-oesophageal reflux (GOR), is a condition in which stomach acid flows back up into the oesophagus — the tube connecting your mouth to your stomach. This backwash of acid can irritate the lining of the oesophagus, causing a range of uncomfortable symptoms. When acid reflux occurs frequently or severely, it may be diagnosed as gastro-oesophageal reflux disease (GORD). Effective acid reflux treatment in the UK is widely available, ranging from lifestyle adjustments to over-the-counter medicines and prescription therapies.

Occasional Acid Reflux

Many people experience acid reflux occasionally, particularly after eating rich, fatty, or spicy foods, or after drinking alcohol. For most people, this is a temporary nuisance that resolves quickly with simple remedies such as antacids or lifestyle changes.

Chronic Acid Reflux (GORD)

When acid reflux becomes a persistent, recurring problem — occurring two or more times per week — it is classified as GORD. Chronic GORD can damage the oesophageal lining over time and may require ongoing management with prescription-strength medicines such as proton pump inhibitors (PPIs).

What Causes Acid Reflux?

Acid reflux occurs when the lower oesophageal sphincter — a muscular ring that acts as a valve between the oesophagus and stomach — becomes weakened or relaxes inappropriately, allowing stomach acid to escape upwards. Several lifestyle, dietary, and physiological factors can contribute to this. Understanding the causes is an important step in choosing the right acid reflux remedies for your situation.

  • Diet: Spicy foods, fatty meals, chocolate, caffeine, citrus fruits, and tomato-based products are common triggers.
  • Alcohol and smoking: Both can weaken the lower oesophageal sphincter and increase stomach acid production.
  • Excess weight: Being overweight or obese increases pressure on the abdomen, pushing acid upwards.
  • Pregnancy: Hormonal changes and the growing uterus can cause acid reflux, particularly in the third trimester.
  • Hiatus hernia: When part of the stomach pushes through the diaphragm, it can impair the valve mechanism.
  • Certain medications: Ibuprofen, aspirin, and some blood pressure medicines can aggravate reflux symptoms.

How Do Acid Reflux Treatments Work?

Acid reflux treatments work through different mechanisms depending on their type. The goal of each is to either neutralise existing stomach acid, reduce the amount of acid produced, or protect the oesophageal lining from further damage. Choosing the most appropriate treatment depends on the frequency and severity of your symptoms, and it is always advisable to speak to a pharmacist or GP if you are unsure which option is best suited to you.

Antacids

Antacids such as calcium carbonate, magnesium hydroxide, and sodium alginate work by neutralising stomach acid quickly. They provide fast, short-term relief and are ideal for mild, occasional heartburn. Alginate-based products such as Gaviscon also form a protective raft on top of stomach contents, helping to prevent acid from rising into the oesophagus.

H2 Blockers

H2 receptor antagonists, such as famotidine, reduce the amount of acid produced by the stomach by blocking histamine receptors. They act more slowly than antacids but provide longer-lasting relief, making them suitable for more regular symptoms. They are available over the counter for short-term use.

Proton Pump Inhibitors (PPIs)

PPIs such as omeprazole and lansoprazole are among the most commonly used medicines for acid reflux treatment in the UK. They work by blocking the proton pumps in the stomach lining that produce acid, significantly reducing acid output. Omeprazole for acid reflux in the UK is available both over the counter and on prescription, depending on the dose and duration of treatment required.

Are There Any Side Effects?

Most acid reflux medicines are well tolerated when used as directed, but side effects can occur. Common side effects of antacids include constipation or diarrhoea, depending on the active ingredient. PPIs such as omeprazole may occasionally cause headaches, nausea, or stomach discomfort, particularly when used long term. If you experience persistent or unusual side effects, stop use and consult your pharmacist or GP for further guidance. For related digestive discomfort, our indigestion range includes effective over-the-counter options.

Who Can Use Acid Reflux Treatments?

Most over-the-counter acid reflux remedies in the UK are suitable for adults aged 18 and over. Some antacids, such as certain alginate preparations, may be used in younger age groups under pharmacist guidance. Pregnant or breastfeeding women should seek advice from a pharmacist or GP before starting any new treatment, as not all products are suitable during pregnancy. Individuals taking regular prescribed medications should also check for potential interactions before purchasing heartburn relief tablets or other acid reflux medicines.
