Acidity and Gastro-oesophageal Reflux

Seek Prompt Medical Assessment If

• Swallowing is becoming difficult, painful or progressively worse.
• Food repeatedly feels stuck, or choking and regurgitation occur during meals.
• There is unexplained weight loss, loss of appetite, persistent vomiting or early fullness.
• Anaemia, bleeding, black stool or recurrent vomiting is suspected.
• Symptoms are new later in life, persistent despite supervised care, or changing in character.
• There is a strong family history of upper digestive cancer or a known Barrett’s oesophagus diagnosis.

These findings do not automatically mean cancer, but they change the urgency and may require endoscopy or specialist assessment rather than repeated symptom treatment.

Four Terms That Are Often Mixed Together

Common Reflux Symptoms

• Burning behind the breastbone, especially after eating, bending or lying down.
• Sour, bitter or food-tasting material rising into the throat or mouth.
• Upper-abdominal or lower-chest discomfort associated with meals.
• Night-time symptoms, disturbed sleep or symptoms on waking.
• Excess saliva, an unpleasant taste or repeated throat clearing.

Cough, hoarseness, throat discomfort, wheeze and dental erosion can occur alongside reflux, but none proves that reflux is the cause. Lung, heart, ENT, allergy and other explanations may need separate assessment.

What Can Contribute?

• A lower oesophageal valve that relaxes at inappropriate times or does not prevent backflow effectively.
• A hiatus hernia, in which part of the stomach moves through the diaphragm opening.
• Pregnancy or increased abdominal pressure.
• Central adiposity, tobacco use or an individual pattern of alcohol intake.
• Large or late meals and personally reproducible food triggers.
• Delayed stomach emptying or an oesophageal movement disorder.
• Selected prescriptions that affect the valve, the oesophagus or stomach emptying.

A food that triggers one person may not affect another. Very broad exclusion diets can be difficult to sustain and may create nutritional problems without clarifying the diagnosis.

Reflux Is Not the Same as Gastritis, Ulcer or “Gas”

Gallbladder, pancreatic, cardiac and medication-related problems can also resemble “acidity.” The site, timing and quality of pain help, but they do not replace assessment.

How Is Reflux Diagnosed?

Typical heartburn and regurgitation without warning features can often be assessed from a careful history and examination. The clinician will review timing, food and position, swallowing, bleeding, weight change, prescriptions, pregnancy, tobacco and alcohol, heart risk and previous treatment response.

Testing is considered when warning features are present, the diagnosis is uncertain, symptoms persist despite an appropriate supervised plan, complications are suspected, or an invasive treatment is being considered.

What Tests May Be Used?

Helicobacter pylori and Reflux Answer Different Questions

Helicobacter pylori is a stomach bacterium associated with gastritis and peptic ulcer disease. A positive test does not prove that reflux caused the symptoms, and a negative test does not exclude GORD. Testing should be chosen for the clinical question and performed under instructions, because recent acid-suppressing treatment can affect some test results.

If infection is confirmed, eradication and later confirmation of clearance should follow a clinician-directed plan. Do not reuse an old prescription or combine treatments independently.

Treatment Principles

• Match meal size, timing and personally confirmed triggers to the individual symptom pattern.
• For night-time symptoms, the clinician may discuss avoiding meals close to lying down and positioning strategies.
• Address tobacco, alcohol and weight-related factors respectfully when they are relevant.
• Use clinician-directed acid-suppressing treatment for an appropriate duration, then review response and ongoing need.
• Check timing, adherence, diagnosis and alternative causes before escalating long-term treatment.
• Consider procedural or surgical options only for selected people with objective reflux and an appropriate specialist assessment.

Do not start, stop, double or continue treatment indefinitely from internet advice alone. Persistent symptoms do not always mean that more acid suppression is the correct answer.

Possible Complications

• Oesophagitis, erosion or bleeding.
• Scar-related narrowing that causes progressive swallowing difficulty.
• Barrett’s oesophagus, in which the lining changes after long-term exposure in some people.
• Less commonly, respiratory, throat or dental complications in a compatible clinical pattern.

Barrett’s oesophagus is not cancer, but it can increase future risk and may require an individual surveillance plan. Most people with reflux do not develop Barrett’s or cancer.

Pregnancy, Children and Older Adults

• Pregnancy: reflux is common, but chest pain, bleeding, dehydration, persistent vomiting, severe abdominal pain or swallowing difficulty still needs assessment. Treatment choices should be pregnancy-specific.
• Children: feeding difficulty, poor growth, recurrent choking, breathing symptoms, blood, persistent vomiting or swallowing problems require a child-specific pathway.
• Older adults: new symptoms, anaemia, weight loss or swallowing difficulty should not be repeatedly labelled as acidity without investigation.

When Is Specialist Care Appropriate?

• There is dysphagia, painful swallowing, food impaction, bleeding, anaemia, persistent vomiting or unexplained weight loss.
• Symptoms remain troublesome or unexplained after an appropriate supervised assessment and treatment trial.
• Endoscopy shows severe inflammation, narrowing, Barrett’s change, ulceration or another abnormality needing follow-up.
• The diagnosis is uncertain and reflux monitoring or oesophageal function testing may change care.
• A hiatus hernia is large or complicated, or a procedure is being considered.
• Symptoms are atypical, recurrent after stopping treatment or associated with repeated respiratory or throat complaints.
