Acid reflux is treated in three layers, and most people get relief in the first one: change when and how you eat, drink and sleep; add an acid-lowering medicine chosen by a doctor if that is not enough; and investigate further only if symptoms continue despite both. The order matters — people who start with a tablet and change nothing else usually find the burning returns the moment the tablet stops.
Before anything else: heartburn is common, but some chest symptoms are not reflux. Severe or crushing chest pain, pain spreading to the jaw, arm or back, chest pain with sweating, breathlessness or sudden weakness, vomiting blood, black stools, difficulty swallowing or unexplained weight loss all need emergency assessment straight away, not self-treatment.
The three layers, in order
- Timing and habits. The seven steps below, given a fair trial of two to four weeks rather than two or three days.
- Medicines. Antacids and alginates for fast, short relief; acid-reducing and acid-suppressing classes for a defined course decided by a doctor.
- Assessment. For symptoms that persist, come straight back when the medicine stops, or arrive with any warning sign.
Step 1: Leave three hours between your last meal and lying down
Reflux is mechanical before it is chemical. A full stomach pressing against the valve at the top of the stomach, plus a horizontal body, is the single most reliable way to push acid upward. Late dinners are the most common reason a person with otherwise mild reflux is woken at two in the morning by burning behind the breastbone or a sour taste at the back of the throat. Eat earlier, and keep the last meal of the day the smallest one.
Step 2: Raise the head of the bed, not your head on the pillow
Stacking pillows bends the body at the waist and increases pressure on the stomach, which makes reflux worse rather than better. Instead, lift the head end of the whole bed by roughly the height of a brick, or slide a firm wedge under the mattress, so the whole upper body sits on a gentle slope and gravity works along the length of the food pipe all night. Sleeping on the left side helps as well, because of where the stomach sits in relation to its own outlet.
Step 3: Take pressure off the stomach
Anything that squeezes the abdomen pushes its contents toward the chest: a tight belt or waistband, heavy lifting, straining, constipation, and weight carried around the middle. Losing a modest amount of weight — not a dramatic amount — is one of the few measures with genuinely good evidence behind it for people who are overweight. Smoking is the other big lever, because it weakens the valve that is supposed to stay shut, and reflux often improves noticeably in people who stop.
Step 4: Eat smaller and slower
Two moderate meals cause less reflux than one large one of the same total size. Eating quickly swallows air, distends the stomach and delays the point at which it empties. Loosen the belt at the table, put the fork down between mouthfuls, and stay upright for a while after eating — a short walk is fine, lying on the sofa is not.
Step 5: Find your own triggers instead of banning every food
Long lists of forbidden foods circulate online and most of them are useless for most people, because triggers are individual. The usual suspects are large fatty or fried meals, coffee, chocolate, peppermint, citrus, tomato-based sauces, very spicy food, fizzy drinks and alcohol — but you may react to two of those and none of the rest. Keep a simple diary for two weeks: what you ate, when, and whether symptoms followed within a couple of hours. Remove what your own diary convicts, and keep eating the rest.
Step 6: Use the right medicine for the right job
Medicines for reflux are not interchangeable. Each class works differently, and knowing which is which stops people from taking a fast-acting product for a problem that needs a proper course, or a long-term product for occasional heartburn.
- Antacids neutralise acid that is already in the stomach. They work within minutes and wear off within an hour or two — useful for an occasional episode, not a treatment plan.
- Alginates form a raft that floats on the stomach contents and acts as a physical barrier. They are often helpful after meals and at bedtime, and they can be used alongside other treatment.
- Acid-reducing medicines (H2 receptor blockers) lower how much acid the stomach makes. They act more slowly than an antacid but last longer, and are sometimes used for night-time symptoms.
- Acid-suppressing medicines (proton pump inhibitors) produce the strongest reduction in acid. They build up over several days rather than working instantly, are usually taken before food, and are prescribed as a defined course with a review at the end.
Choice, strength and length of course are medical decisions, which is why this article names classes and not products. Mention every medicine you already take, because some common ones — certain painkillers and anti-inflammatories, some blood pressure medicines, some bone and iron preparations — aggravate reflux or irritate the food pipe directly. Changing one of those sometimes does more than adding another tablet.
How long should treatment last?
Most courses are measured in weeks, followed by a review rather than an open-ended repeat. Stopping a strong acid-suppressing medicine abruptly after months of use can cause a temporary surge of symptoms, which people misread as proof they need it forever; stepping down gradually, under supervision, avoids that trap. If symptoms return immediately every time treatment stops, that is information your doctor needs, not a reason to quietly continue indefinitely.
Step 7: Stop doing the things that do not help
- Milk. It soothes for a few minutes, then stimulates more acid.
- Bicarbonate of soda from the kitchen. It neutralises acid, but it is a large salt load and is not something to repeat day after day.
- Peppermint tea. Widely assumed to settle the stomach; it relaxes the very valve you are trying to keep shut.
- Waiting it out for years. Reflux that is left untreated for a long time can inflame and scar the lining of the food pipe, and that is worth preventing.
When reflux should be assessed rather than self-treated
Arrange a medical review if symptoms occur more than twice a week for several weeks, if they wake you at night, if they come straight back at the end of every course of treatment, or if they started for the first time in middle age or later. The same applies to the less obvious faces of reflux: a chronic dry cough, hoarseness, a persistent lump-in-the-throat sensation, recurrent sore throat or dental erosion. Depending on the picture, your doctor may refer you for tests such as a camera examination of the food pipe and stomach or acid monitoring — decided case by case, not routinely for everyone.
Warning signs that need emergency care now
Go straight to a 24-hour emergency department, immediately, and do not wait for an appointment, if you have severe or crushing chest pain, chest pain spreading to the jaw, arm or back, pain with sweating or breathlessness, sudden weakness, vomiting of blood or of material that looks like coffee grounds, black tarry stools, or food that is stuck so that you cannot swallow your own saliva. Heart pain and reflux pain can feel identical, and heart pain has to be excluded first — that decision is made in an emergency department, not at home.
Other symptoms are not emergencies but should be assessed without delay: swallowing that is becoming progressively harder, weight loss you did not intend, repeated vomiting, or unexplained anaemia.
Reflux during pregnancy
Heartburn in pregnancy is extremely common, caused by hormonal relaxation of the valve combined with upward pressure from the growing uterus. The measures that apply in pregnancy are timing of the last meal, raising the head of the bed, smaller and more frequent meals, loose waistbands, and staying upright after eating. Weight loss is not part of the plan during pregnancy. Any medicine during pregnancy must be chosen by the doctor following the pregnancy, including products sold without a prescription.
How to tell whether the treatment is working
Track three simple numbers for a month: how many nights you were woken, how many daytime episodes you had in a week, and how often you reached for a fast-acting antacid. If those numbers are falling, the plan is working and the next question is how far the medicine can be stepped down. If they are unchanged after a fair trial, the assumption that acid is the whole problem deserves to be re-examined — a persistent burning chest is not always reflux, and treating the wrong thing costs time. The realistic goal is fewer episodes, undisturbed sleep and the smallest amount of medicine that keeps things quiet.
Frequently Asked Questions
What is the best acid reflux treatment to start with?
The most effective acid reflux treatment to start with is timing rather than tablets: leave about three hours between your last meal and lying down, raise the head end of the bed, eat smaller meals and take pressure off the abdomen. If symptoms persist after two to four weeks of doing that consistently, a doctor may add a medicine — antacids or alginates for short relief, or an acid-reducing or acid-suppressing class for a defined course. The choice, strength and duration are medical decisions and should be reviewed at the end of the course rather than repeated indefinitely.
How do I know that what I have is acid reflux?
Acid reflux typically causes burning behind the breastbone that is worse after meals and when lying down, a sour or bitter taste at the back of the throat, and sometimes a dry cough, hoarseness or a lump-in-the-throat feeling. Symptoms that appear at night or after a late heavy meal point strongly in that direction. Chest pain can also come from the heart, so severe or crushing pain, or pain with sweating, breathlessness or sudden weakness, must be assessed in an emergency department immediately rather than assumed to be reflux.
What is acid reflux, exactly?
Acid reflux is the backward flow of stomach contents into the food pipe, which happens when the muscular valve between the two does not stay closed as it should. The stomach lining is built to handle acid and the food pipe is not, which is why the result is felt as burning. Occasional episodes are normal; when reflux happens frequently or causes ongoing symptoms and inflammation, it is called gastro-oesophageal reflux disease and is managed with habit changes, medication, and assessment when it does not settle.
