The fastest way to get rid of acid reflux is to neutralize the acid that’s already in your esophagus. An over-the-counter antacid can do this within minutes, but if you don’t have one on hand, simple changes to your body position, what you drink, and how you breathe can all bring noticeable relief within 15 to 30 minutes.
Antacids Work Within Minutes
If you have access to a drugstore or medicine cabinet, chewable antacids containing calcium carbonate are the single fastest option. They neutralize stomach acid on contact, and most people feel relief within 5 to 10 minutes. These are purely reactive, though. They stop the burn you’re feeling right now but don’t prevent the next episode.
H2 blockers (like famotidine) take 30 to 60 minutes to kick in but suppress acid production for up to 12 hours. Proton pump inhibitors, or PPIs, are not useful for immediate relief. They need one to four days of consistent use to reach full effect, so they’re better suited for recurring reflux rather than a flare-up happening right now.
Change Your Position Immediately
If you’re lying flat or slouched on the couch, sit up or stand. Gravity is your simplest tool. When you’re upright, acid has to fight its way uphill to reach your esophagus, which dramatically reduces the burning sensation.
If you need to lie down, roll onto your left side. Your stomach sits slightly to the left of your esophagus, so in this position the junction between the two sits above the pool of acid rather than below it. Research from Amsterdam UMC confirmed that left-side sleeping reduces the amount of acid that travels back into the esophagus. Lying on your right side or flat on your back does the opposite, letting acid pool right at the opening. Elevating the head of your bed by 6 to 8 inches (using a wedge pillow or blocks under the bedframe legs) adds another layer of gravity-assisted protection if nighttime reflux is a recurring problem.
Baking Soda as a Quick Home Remedy
Baking soda (sodium bicarbonate) is a base that neutralizes stomach acid almost instantly. According to Mayo Clinic dosing guidance, dissolve half a teaspoon in a full glass of cold water and drink it. You can repeat this every two hours if needed, but don’t exceed five teaspoons total in a day. The relief is fast, often within five minutes, but temporary.
This is a reasonable occasional fix, not a daily habit. Baking soda is high in sodium, and regular use can disrupt electrolyte balance or cause bloating and gas from the carbon dioxide it produces when it reacts with acid.
What to Drink (and What to Skip)
Plain water helps by diluting stomach acid and washing any acid in your esophagus back down. Sip it slowly rather than gulping, since a large volume of liquid all at once can stretch the stomach and make things worse.
There’s some evidence that alkaline water with a pH of 8.8 goes a step further. A study published in the Annals of Otology, Rhinology, and Laryngology found that water at this pH permanently inactivated pepsin, a digestive enzyme that damages esophageal tissue when it refluxes up from the stomach. Regular tap water doesn’t do this. Whether this translates to meaningful symptom relief in everyday life is less clear, but it’s unlikely to cause harm.
Avoid anything carbonated, citrus juices, coffee, and alcohol while you’re symptomatic. All of these either relax the muscular valve at the top of your stomach or directly irritate the esophageal lining.
Chew Gum for 30 Minutes
Chewing sugar-free gum after a meal stimulates saliva production, and saliva is mildly alkaline. The swallowing motion repeatedly pushes acid back down into your stomach while the bicarbonate in your saliva helps neutralize what’s left behind. A 2005 study found that chewing gum for 30 minutes after eating reduced reflux symptoms. It won’t stop a severe episode, but for mild post-meal heartburn, it’s a surprisingly effective and free option. Avoid peppermint-flavored gum, since peppermint relaxes the valve between your stomach and esophagus.
Diaphragmatic Breathing
This one sounds unlikely, but there’s solid evidence behind it. The valve that keeps acid in your stomach (the lower esophageal sphincter) is reinforced by the diaphragm, the large muscle you use to breathe. A meta-analysis of randomized controlled trials found that targeted breathing exercises significantly increased the pressure this valve generates, strengthening the body’s natural anti-reflux barrier. The diaphragm is a skeletal muscle, which means it responds to training just like any other muscle.
The technique is simple: sit or lie comfortably, place one hand on your chest and one on your belly, and breathe deeply so that only your belly rises. Your chest should stay relatively still. Inhale slowly through your nose for four seconds, hold briefly, then exhale through pursed lips for six seconds. Doing this for 5 to 10 minutes during an episode can help, and practicing daily builds long-term protection against reflux.
Foods That Trigger Reflux
If your reflux just started, think about what you ate in the last hour or two. Certain foods relax the valve at the top of your stomach and slow digestion, leaving food sitting longer and producing more acid. The worst offenders, per Johns Hopkins Medicine, include fried foods, fast food, fatty meats like bacon and sausage, cheese, pizza, and processed snacks like potato chips. Tomato-based sauces, citrus fruits, chocolate, peppermint, and carbonated drinks cause the same problem.
You can’t undo what you’ve already eaten, but knowing your triggers helps you prevent the next episode. Eating smaller meals, finishing dinner at least three hours before bed, and avoiding tight-fitting clothing around your waist all reduce the mechanical pressure that pushes acid upward.
Ginger for Lingering Symptoms
Ginger speeds up the rate at which your stomach empties into the small intestine, meaning food and acid spend less time sitting in your stomach where they can reflux. Research suggests that roughly 1,500 mg of ginger per day (about a tablespoon of fresh grated ginger) can improve upper digestive symptoms including reflux. Ginger tea or ginger chews are the easiest ways to get this during an active episode. It won’t work as fast as an antacid, but it helps the underlying sluggish digestion that often contributes to reflux.
When Reflux Might Be Something Else
Acid reflux and heart problems can feel remarkably similar. Even experienced physicians sometimes can’t distinguish them based on symptoms alone. Typical reflux causes a burning sensation in the chest, usually after eating or lying down, often with a sour taste in the mouth. It generally improves with antacids.
A heart attack more commonly involves pressure, tightness, or squeezing in the chest that may radiate to the neck, jaw, or arms. It’s often accompanied by shortness of breath, cold sweat, lightheadedness, or sudden fatigue. If your chest discomfort came on during physical exertion, feels like pressure rather than burning, or is accompanied by any of those additional symptoms, call emergency services. This is one situation where it’s better to be wrong than to wait it out.
