THE ESSENTIALS

  • Night-time symptoms may improve with an earlier final meal.
  • Identify your own triggers instead of using a universal ban list.
  • Chest symptoms are not automatically reflux.

Know what reflux means

Reflux happens when stomach contents move back into the oesophagus, the tube leading from your mouth to your stomach. Heartburn and a sour taste are common clues. Repeated symptoms or complications may be described as GERD, also called GORD. A cough or hoarse voice can have many causes, so these symptoms alone do not establish reflux.

The word acidity is often used broadly. It can hide important differences between occasional heartburn, persistent reflux, an ulcer and chest symptoms from the heart. Do not use improvement after an antacid as a reliable way to rule out a heart problem.

Change timing before banning everything

For symptoms at night, leaving at least three hours between your meal and lying down may help. Consider whether the evening meal is very large, whether you recline straight afterwards and whether particular drinks reliably coincide with symptoms. Keep the experiment realistic enough to repeat on a working day.

Coffee, alcohol, chocolate, mint, fatty meals, spicy foods and some acidic foods can trigger symptoms in some people. That is not a reason to prohibit every item for everyone. Record what actually happens and discuss persistent symptoms with a clinician. If weight loss is appropriate for you, a gradual, supported approach may help; crash diets are not required.

Adapt your exercise setup

Reflux is often worse after food, while bending or while lying down. As a practical adaptation, schedule strenuous or floor-based exercise away from a large meal. If a particular position brings on symptoms, stop and choose a more comfortable upright activity rather than forcing repetitions.

A relaxed walk may be easier to tolerate than jumping or repeated deep bending immediately after eating. These are comfort adjustments, not treatments for damage to the oesophagus. Recurring symptoms that limit activity still deserve assessment, even if you can work around them temporarily.

Know when self-care is not enough

A pharmacist or clinician can discuss suitable medicines and check interactions. Do not keep increasing over-the-counter products to cover symptoms that occur most days. Difficulty swallowing, food sticking, frequent vomiting or unintentional weight loss needs medical attention.

Bring a list of medicines and supplements to your appointment, along with symptom timing and the changes you have tried. Ask whether you need further investigation, how to take any prescribed treatment and when to review it. A useful plan explains both what to try now and what would mean the diagnosis should be reconsidered.

KNOW WHEN TO GET HELP

When self-care isn’t enough

  • Get emergency help for new chest pressure or tightness, especially with breathlessness, sweating or pain spreading to the jaw or arm.
  • Seek prompt medical care for swallowing difficulty, food sticking, vomiting blood, black stools or unexplained weight loss.

For a medical emergency, contact local emergency services immediately. Do not wait for an online response.
