01 · Know
What is Heartburn and Acid Reflux?
Heartburn and acid reflux happen when stomach acid flows back up into the oesophagus, causing a burning sensation in the chest or throat, often alongside a sour taste in the mouth. It's common and can be triggered by certain foods, eating large meals, lying down soon after eating, being overweight, or pregnancy.
Occasional heartburn is usually easily managed with simple lifestyle changes and over-the-counter treatments, while frequent or severe symptoms may need further investigation and stronger treatment to protect the oesophagus from ongoing acid exposure.
02 · Understand
Clinical context
Frequent symptoms deserve proper assessment, not just repeated antacid use
If you're using antacids regularly, several times a week, it's worth seeing a doctor rather than just continuing to self-treat, since frequent reflux can sometimes need stronger treatment or further investigation.
03 · Act
When to See a Doctor
- 1Heartburn occurs frequently, several times a week
- 2You have difficulty swallowing, or pain when swallowing
- 3You notice unexplained weight loss alongside reflux symptoms
- 4Symptoms aren't improving with over-the-counter treatments
04 · Prevent & manage
Practical steps
Difficulty Swallowing Always Needs Assessment
While heartburn itself is usually not serious, difficulty or pain when swallowing alongside reflux symptoms should always be assessed by a doctor rather than managed with self-care alone.
- 1Eat smaller, more frequent meals.This puts less pressure on the stomach than large meals.
- 2Avoid eating close to bedtime.Leave a few hours between your last meal and lying down.
- 3Elevate the head of your bed slightly.This can reduce nighttime symptoms by using gravity to help keep acid down.
- 4Identify and avoid your specific trigger foods.Common triggers include spicy, fatty, or acidic foods, along with caffeine and alcohol.
- 5Try an over-the-counter antacid.These provide quick relief for occasional symptoms — see a doctor if you need them frequently.
