GERD and heartburn: relief without overusing medicines

# GERD and heartburn: relief without overusing medicines

Heartburn is a burning feeling behind the breastbone caused when stomach contents move into the oesophagus. Occasional reflux is common; gastro-oesophageal reflux disease, or GERD, means symptoms are troublesome, recurrent, or have caused injury. Chest discomfort should never be self-diagnosed when a heart cause is possible.

Why reflux happens

The lower oesophageal sphincter and diaphragm normally limit backward flow. Large or late meals, excess abdominal weight, pregnancy, a hiatus hernia, smoking, and some medicines can weaken that barrier or increase pressure. Food triggers differ: fat, chocolate, peppermint, coffee, tomato, or spice may matter to one person and not another, so broad permanent restrictions are rarely necessary.

Lifestyle changes that work

Avoid lying down for two to three hours after eating and make the evening meal smaller if night symptoms dominate. Raising the head end of the bed—not simply adding pillows—can reduce nocturnal reflux. Weight loss helps when excess weight is present. Stop smoking, moderate alcohol, and identify personal triggers with a brief diary rather than eliminating many nutritious foods at once.

PPIs: useful, but use them correctly

Proton-pump inhibitors are the most effective medicines for healing reflux oesophagitis. They usually work best 30–60 minutes before breakfast; twice-daily treatment, if prescribed, is taken before breakfast and dinner. A clinician should review the indication, lowest effective dose, and duration. Fear-driven abrupt stopping can cause rebound acid, while indefinite unreviewed use can expose patients to unnecessary cost and interactions.

When endoscopy is needed

Upper endoscopy is important for difficulty or pain with swallowing, bleeding, anaemia, persistent vomiting, weight loss, or symptoms that do not respond to a correctly taken treatment trial. It may also be advised according to Barrett’s oesophagus risk. Many people with typical uncomplicated reflux do not need immediate endoscopy; a normal scope also does not exclude reflux, and selected patients may need pH monitoring.

Throat, cough, and voice symptoms

Reflux may contribute to chronic cough, throat clearing, hoarseness, a lump sensation, or asthma-like symptoms, but these complaints have many other causes. Dental disease, allergy, post-nasal drip, smoking, asthma, and voice strain may be more likely. A response to acid suppression does not by itself prove reflux, because symptoms naturally vary and placebo effects occur. When typical heartburn is absent, clinicians often coordinate ear, nose and throat or respiratory assessment and may use reflux monitoring before committing someone to long-term high-dose treatment.

Barrett’s oesophagus and cancer risk

Repeated acid exposure can replace the normal lower-oesophageal lining with Barrett’s tissue. Barrett’s is not cancer, and most people with it never develop cancer, but it modestly increases risk and may require surveillance when confirmed by biopsy. Screening endoscopy is not offered to everyone with reflux. It is considered when several risk factors cluster, such as long-standing symptoms, older age, male sex, central obesity, smoking, or a first-degree family history of Barrett’s or oesophageal adenocarcinoma. The decision should reflect the person’s overall health and preferences.

Reflux during pregnancy

Heartburn is common in pregnancy because hormones relax the reflux barrier and the growing uterus raises abdominal pressure. Smaller meals, avoiding food close to bedtime, and remaining upright after eating are useful first steps. Medicine choices should be discussed with the obstetric or medical team; selected antacids, alginate preparations, H2 blockers, or PPIs may be used when benefits outweigh risks. New severe chest or upper-abdominal pain, vomiting blood, difficulty swallowing, headache with high blood pressure, or pain accompanied by breathlessness should not be attributed to ordinary pregnancy reflux.

When pH monitoring or surgery enters the discussion

Ambulatory reflux monitoring measures acid exposure and the relationship between episodes and symptoms. It is useful when the diagnosis remains uncertain, before anti-reflux surgery, or when troublesome symptoms persist despite correctly used medication and endoscopy has not supplied the answer. Manometry assesses oesophageal movement and locates the sphincter before some procedures; it does not diagnose reflux on its own. Surgery or endoscopic anti-reflux treatment may suit carefully selected patients with objectively proven reflux, troublesome regurgitation, or a large hiatus hernia, but it carries side effects and is not a shortcut around proper testing.

Myths and facts

Acid is always the result of spicy food

The barrier mechanism, meal timing, and weight often matter more.

PPIs are addictive

They are not addictive, though rebound acid can occur after abrupt withdrawal.

Everyone with heartburn needs a scope

Typical uncomplicated symptoms can often be treated first without endoscopy.

When to see a doctor

Review reflux soon if it occurs several times weekly, requires frequent over-the-counter medicine, disturbs sleep, or returns whenever treatment stops. Difficulty or pain with swallowing, food impaction, bleeding, anaemia, persistent vomiting, or unplanned weight loss requires earlier investigation. Call emergency services for new pressure-like chest pain, especially with sweating, nausea, breathlessness, exertion, or pain spreading to the arm, back, neck, or jaw; heart symptoms can mimic indigestion and should not wait for an acid remedy to work.

Practical checklist

• Record meals, timing, symptoms, and night waking for two weeks.
• Take prescribed PPI before food at the instructed time.
• Avoid late meals and raise the bed head for night reflux.
• Seek urgent help for chest pressure with sweating, breathlessness, or pain spreading to arm or jaw.
