Heartburn is the burning discomfort caused when stomach contents move back towards the oesophagus. Large meals, eating close to bed, alcohol and some fatty or spicy foods are common triggers, but the pattern is personal. Coffee may be troublesome for one person and entirely manageable for another.
A simple two-week diary can be more useful than a universal avoidance list. Note what you ate, the portion, the time and when symptoms appeared. Change one likely factor at a time, such as making the evening meal smaller or staying upright after eating, so you can tell what actually helps.
A pharmacist or GP can advise about treatment when lifestyle changes are not enough. Seek medical advice if symptoms are frequent, swallowing is difficult, food sticks, you are losing weight without trying, you vomit blood or your stool is black. Chest pain that could be cardiac needs urgent assessment rather than being assumed to be indigestion.
This article offers general information and does not replace advice from someone who knows your medical history. If you are pregnant, take regular medicine or live with a long-term condition, speak to your GP, nurse, pharmacist or a registered dietitian before making a major change to the way you eat.
What heartburn is (briefly)
Heartburn occurs when stomach contents move back into the oesophagus. Meal size, timing, pregnancy, body position, some medicines and a hiatus hernia can all contribute, so food is only one part of the picture.
Keep a short record before removing many foods. Difficulty swallowing, food sticking, unexplained weight loss, anaemia, vomiting blood or black stools needs prompt medical assessment.
Common food and drink triggers
Fatty meals, chocolate, peppermint, coffee, alcohol and fizzy drinks are common triggers, while spicy food, onion, garlic or acidic ingredients affect some people and not others. Portion and timing may matter as much as the ingredient itself.
Change one likely factor at a time. A smaller earlier supper is a more useful experiment than buying a collection of products labelled reflux-friendly.
Try to leave two or three hours between a substantial meal and lying down. Shift workers can apply the same principle relative to their own sleep time.
If genuine hunger appears later, choose a small snack such as yoghurt, fruit or toast. Raising the head of the bed may help some people when advised, while extra pillows alone often bend the body without preventing reflux.
A moderate plate with vegetables, protein and a suitable amount of starch may feel easier than a very large rich meal. Eat sitting down and pause midway so fullness has time to register.
Plan two lighter dinners for the evenings symptoms are most likely. Lentil soup, a vegetable tray bake or a smaller mince dish stretched with pulses can still be satisfying.
Mediterranean pattern without a lecture
A Mediterranean-style pattern offers vegetables, pulses, fish, yoghurt, grains and unsaturated oils without relying on frequent deep-fried meals. It is not automatically reflux-free, but its balance and portion flexibility may be helpful.
Use familiar supermarket foods and test your own tolerance. Do not force yourself to finish a large amount of cheese or another rich food simply to avoid waste; refrigerate or freeze it safely instead.
Plan meals before the reflux week
Compare meal size and richness across the week, and keep one freezer portion for evenings when nausea or fatigue makes cooking difficult. A planned option reduces late heavy takeaways.
Frequent symptoms still need clinical review. A pharmacist can advise about short-term relief, while persistent reflux may require investigation and a longer-term treatment plan.
