When acid reflux hits, your fastest relief comes from neutralizing the acid already in your esophagus and reducing the pressure pushing more acid upward. Most people can calm an attack within minutes by combining a few simple physical adjustments with an over-the-counter antacid. Here’s exactly what to do, step by step.
Loosen Your Clothing First
If you’re wearing anything snug around your midsection, undo it immediately. Tight waistbands, belts, and shapewear squeeze your abdomen and force stomach contents upward. A study published in Gastroenterology found that compression from a waist belt caused an 8-fold increase in acid reflux after a meal. The belt also tripled the time it took for acid to clear from the esophagus, from about 23 seconds without compression to over 81 seconds with it. Loosening or removing that pressure is one of the simplest things you can do, and it makes every other step more effective.
Stand Up or Elevate Your Upper Body
Gravity is your ally during a reflux attack. If you’re lying down, sit up or stand. If you need to stay in bed, prop your upper body at least 6 to 8 inches higher than your stomach using a wedge pillow or stacked pillows. Simply propping your head isn’t enough; you need your entire torso angled upward so gravity can pull acid back down into your stomach.
If you’re going to lie on your side, choose the left side. Research from Harvard Health found that while sleeping position didn’t change how often acid entered the esophagus, acid cleared significantly faster when people lay on their left side compared to their right side or back. The anatomy works in your favor: your stomach curves in a way that keeps acid pooled away from the opening to your esophagus when you’re on your left.
Take an Antacid for the Fastest Relief
Chewable antacids (the calcium carbonate tablets you find at any pharmacy) work within minutes by directly neutralizing stomach acid. They’re the fastest-acting option for an acute attack, though the relief tends to be short-lived, usually lasting 30 to 60 minutes.
If you want longer-lasting relief, an H2 blocker takes about an hour to kick in but suppresses acid production for several hours. You can take an antacid and an H2 blocker together: the antacid handles the immediate burn while the H2 blocker prevents the next wave.
Proton pump inhibitors (PPIs) are not helpful during an active attack. They take one to four days to reach full effectiveness and are designed for ongoing prevention, not acute relief.
Sip Water to Wash Acid Down
A few slow sips of water can help rinse acid out of your esophagus and dilute what’s sitting in your stomach. You don’t need to chug a full glass, as too much liquid at once can increase stomach volume and make things worse. Small, deliberate sips work best.
Alkaline water with a pH of 8.8 may offer a slight additional benefit. One of the enzymes your stomach produces, pepsin, can lodge in the tissues of your esophagus during reflux episodes and continue causing irritation. Alkaline water helps neutralize that enzyme. Regular water still helps, though, so don’t skip this step just because you don’t have alkaline water on hand.
Chew Sugar-Free Gum
This one sounds oddly simple, but chewing gum stimulates saliva production, and saliva naturally contains bicarbonate, a compound that neutralizes acid. The extra saliva you swallow during 20 to 30 minutes of chewing helps wash acid out of the esophagus and buffer what remains. Bicarbonate gum, if you can find it, amplifies this effect. Avoid mint-flavored gum, since peppermint can relax the valve between your stomach and esophagus and potentially make reflux worse.
Try Baking Soda as a Last Resort
If you don’t have antacids available, dissolving half a teaspoon of baking soda (sodium bicarbonate) in a full glass of water creates a basic antacid. It neutralizes stomach acid quickly and can provide temporary relief. Don’t exceed half a teaspoon per dose or use it more than a few times in a day.
This isn’t a good option for everyone. Baking soda is high in sodium and can cause your body to retain water. If you have high blood pressure or are on a sodium-restricted diet, skip it entirely. It’s also not meant for regular use; it’s a one-time fix when you have nothing else available.
Avoid These Common Mistakes
During an attack, your instincts can work against you. Don’t lie flat, even if you feel like resting. Don’t drink milk, which may feel soothing initially but stimulates more acid production as your stomach digests the fat and protein. Don’t eat anything to “absorb” the acid. Your stomach is already struggling to manage what’s in it, and adding food gives it more reason to produce acid.
Bending over or doing any physical activity that compresses your abdomen will make things worse. If you need to pick something up, bend at the knees instead of the waist. Avoid carbonated drinks, which introduce gas into your stomach and increase internal pressure.
What to Do After the Attack Passes
Once the burning subsides, wait at least two to three hours before lying down. If the attack happened after a meal, that waiting period lets your stomach empty enough to reduce the chance of a second episode. Ginger tea or a small amount of fresh ginger may help speed gastric emptying, moving food out of your stomach and into the small intestine faster so your stomach can stop producing as much acid.
Keep a mental note of what triggered the attack. Common culprits include large meals, fatty or fried foods, tomato-based sauces, citrus, chocolate, alcohol, and coffee. Eating late at night is one of the most reliable triggers because lying down shortly after a meal gives acid easy access to your esophagus.
When Attacks Become a Pattern
Occasional reflux is normal. Most adults experience it a few times a month without any lasting harm. But if you’re reaching for antacids more than twice a week, or if attacks are waking you up at night regularly, that pattern typically indicates gastroesophageal reflux disease (GERD). The distinction matters because repeated acid exposure damages the lining of your esophagus over time, and GERD responds better to daily preventive treatment than to treating each attack individually.
Certain symptoms during an attack also warrant prompt medical attention: difficulty swallowing, a feeling that food is stuck in your chest, vomiting blood, or unexplained weight loss. Chest pain from reflux can also mimic a heart attack, so if you have any doubt about whether the pain is cardiac or digestive, treat it as cardiac until proven otherwise.
