Health Reference LibraryHow do you get rid of acid reflux? What helps

Summary
Reflux eases when pressure comes off the valve and acid stays out of the oesophagus. NICE advises losing weight where overweight, stopping smoking, and avoiding the triggers a person notices, typically alcohol, coffee, chocolate and fatty foods. The main meal is eaten at least three hours before bed, portions stay smaller, and the head of the bed is raised where symptoms come at night, with left-side sleeping. An alginate or antacid from a pharmacy settles an episode, and for a run of episodes a short course of acid suppression from a pharmacist or GP. No supplement has guideline-level evidence for reflux. Difficulty swallowing, or being over 55 with weight loss, food sticking, vomiting or black stools, needs a GP urgently.
How it works
The lower oesophageal sphincter is a ring of muscle that should stay closed except when swallowing. Anything that raises pressure in the abdomen, a large meal, excess weight around the middle, lying flat soon after eating, forces stomach contents against it, and anything that relaxes the ring, alcohol, smoking, fatty meals, chocolate, some prescriptions, lets them through. Acid touching the oesophageal lining causes the burning, and at night, when swallowing and saliva fall, acid sits longer, which is why raising the bed head and a three-hour gap before lying down matter. Alginates form a raft on top of stomach contents so what refluxes is not acid; acid suppression lowers the acid produced. None of the supplements marketed for reflux acts on the sphincter.
Timing
Meal timing and bed head changes work from the first night. Alginates work within minutes and last a few hours. Weight loss effects build over weeks. A pharmacy or GP acid suppression course runs four to eight weeks. Symptoms that persist beyond that, or come back repeatedly after stopping, need a GP review.
Safety profile
Difficulty swallowing, food sticking, unexplained weight loss, persistent vomiting, vomiting blood, black tarry stools, or new reflux over 55 need a GP within days and usually a two-week endoscopy referral. Chest pain that is crushing, spreads to the arm or jaw, or comes with sweating and breathlessness is a heart attack until proven otherwise, and the response is a 999 call. Long-term acid suppression has trade-offs that a GP reviews, including B12 and magnesium absorption, covered on the [B12 results hub](/apps/learn/b12-blood-test-results-explained-uk-what-your-number-means). Anti-inflammatory painkillers worsen reflux and dyspepsia. Bicarbonate of soda as a home antacid adds sodium and is not for regular use.
Special populations
Pregnancy reflux is common and managed with meal timing, alginates and GP-advised options. People with asthma or a chronic cough may have reflux driving it. Anyone on blood thinners, clopidogrel or thyroid replacement should check interactions with acid suppression through a pharmacist. Older adults with new reflux are the group where the two-week referral rule matters most.
Guideline positions
NICE CG184 on gastro-oesophageal reflux disease and dyspepsia in adults: offer simple lifestyle advice including healthy eating, weight reduction and smoking cessation; advise avoiding known precipitants the person associates with symptoms, which include smoking, alcohol, coffee, chocolate, fatty foods and being overweight; raising the head of the bed and having the main meal well before going to bed may help some people. Community pharmacists are the first line for advice, over-the-counter options and knowing when to see a GP. The NICE quality standard adds a main meal at least three hours before bed. Urgent endoscopy within two weeks is for dysphagia, or age 55 and over with weight loss alongside reflux or dyspepsia. Helicobacter pylori test-and-eradicate is offered for dyspepsia, with a two-week washout after acid suppression before testing.
Practical framework
Two weeks of habits come before any capsule. Meals become smaller and slower, with the main meal at lunchtime or early evening, nothing in the three hours before bed, and a food-and-symptom note to find the personal triggers rather than cutting everything, with coffee, alcohol, chocolate, fatty and very spicy food the common ones. Where the waist is over 94 cm in men or 80 cm in women, even modest weight loss reduces reflux, with the approach on [how to lower blood sugar](/apps/learn/how-to-lower-blood-sugar-what-the-evidence-supports) because the levers overlap. At night the bed head is raised 10 to 15 cm on blocks rather than extra pillows, with left-side sleeping. Smoking stops and tight waistbands loosen. Episodes take an alginate after meals and at bedtime. Where a fortnight of this has not settled it, a pharmacist or GP provides a short acid suppression course and a Helicobacter test. Bloating that comes with it is covered on [how to stop bloating](/apps/learn/how-to-stop-bloating-causes-and-what-actually-works). Nutri365 reads whether reflux tracks meal timing, weight, alcohol or stress across those weeks, checks for interactions and contraindications against anything prescribed, and refers questions outside scope to a health specialist.
Common misconceptions
Reflux is not usually caused by too little stomach acid, and the evidence for acid-increasing supplements in reflux is not at guideline level; what is known is that acid reaching the oesophagus causes the damage. Apple cider vinegar has no trial evidence for reflux and is acidic. Milk settles briefly and then stimulates acid. Extra pillows bend the neck rather than raise the torso and do not help. And supplements sold for reflux act, if at all, on symptoms rather than the valve.
