Reflux: the complete guide

Heartburn and acid reflux are common, and many people notice that meal size, timing and lying down after eating make a difference to how they feel. This page gathers our free reflux articles in one place. Start with the main article on everyday approaches to acid reflux, then read by topic: reflux at night, food and drink, meal timing, and the daily habits people often ask about. The articles explain what the NIH, the NHS, Mayo Clinic and clinical guidelines from gastroenterology organizations say, and each one links to its sources so you can check them yourself. Everything here is general information to use alongside advice from your doctor or pharmacist. Frequent heartburn, or reflux that keeps coming back, is worth discussing with a professional, and some symptoms, such as trouble swallowing, vomiting blood or unexplained weight loss, need prompt medical attention.

Frequently asked questions

What foods cause acid reflux?

Some people notice heartburn around particular foods or drinks, but there is no universal food list that explains everyone's symptoms. Public guidance describes commonly reported associations, not a personal diagnosis. Note what you actually notice and discuss repeated symptoms with your doctor rather than excluding large groups of foods automatically.

What can you eat with acid reflux?

There is no single menu that is appropriate for everyone who experiences reflux. Start with your usual foods, preferences and any professional dietary advice, and note what you personally notice. Broad food bans can make meals unnecessarily restrictive. Ask your doctor or dietitian about persistent symptoms or difficulties finding suitable meals.

What time should I stop eating before bed?

There is no universal clock time because bedtimes and circumstances differ. For nighttime reflux, NIDDK guidance discusses allowing time between eating and lying down. That is general information, not an individual schedule. Discuss how it fits your routine with your healthcare provider, especially if symptoms persist or you have existing dietary instructions.

How to sleep with acid reflux at night?

Nighttime reflux is worth discussing with your doctor, especially when it repeatedly interrupts sleep. Public guidance mentions meal timing and raising the head of the bed, but these are topics to discuss, not a personalized plan. Do not assume chest discomfort is reflux; urgent or worrying symptoms need prompt medical attention.

When should I see a doctor for acid reflux?

Arrange medical advice if reflux is frequent, persistent, worsening or worrying, or if eating and swallowing become difficult. A checklist cannot assess the cause. Chest pain, trouble breathing, vomiting blood or other urgent symptoms should not be assumed to be reflux; seek urgent medical help using your local emergency service.
