The fastest way to get rid of bad heartburn is to take a liquid or chewable antacid, which neutralizes stomach acid on contact and typically brings relief within minutes. But if heartburn keeps coming back, you’ll need a combination of the right medication timing, eating habits, and body positioning to keep it from flaring up. Here’s what actually works, from immediate fixes to longer-term strategies.
Quick Relief Options That Work Right Now
Over-the-counter antacids (the chewable tablets or liquid forms you’ll find at any pharmacy) are your fastest option. They work by directly neutralizing the acid already sitting in your esophagus and stomach, so relief comes within minutes. The tradeoff is that they wear off relatively quickly, usually within an hour or two.
H2 blockers take a different approach. Instead of neutralizing existing acid, they reduce how much acid your stomach produces. They have a quick onset compared to stronger acid-suppressing medications and can be taken on an as-needed basis. You’ll feel the effect within 30 to 60 minutes, and relief lasts several hours.
Proton pump inhibitors (PPIs) are the most powerful option, but they’re not designed for instant relief. They need to be taken 30 to 60 minutes before your first meal of the day, and they require 4 to 8 weeks of daily use to fully suppress acid production. Taking a PPI when heartburn strikes and expecting it to help immediately won’t work. If your heartburn is frequent enough that you’re considering a PPI, that’s a sign you’re dealing with something more than occasional discomfort.
The Baking Soda Fix
Plain baking soda (sodium bicarbonate) is a legitimate antacid you probably already have at home. The recommended dose is half a level teaspoon dissolved completely in 4 ounces of water. You can repeat this every 2 hours if needed, but don’t exceed six half-teaspoon doses in 24 hours. If you’re over 60, the limit drops to three doses per day.
Two important safety notes: never take baking soda until the powder is fully dissolved, and don’t take it when you’re very full from food or drink. Both of these can cause serious injury from rapid gas production in the stomach. If you’re on a sodium-restricted diet, skip this remedy entirely, as baking soda is pure sodium. It also interacts with certain prescription medications, so check with a pharmacist if you take anything regularly.
Chewing Gum After Meals
This one sounds too simple, but chewing sugar-free gum for 30 minutes after eating can reduce heartburn symptoms. The mechanism is straightforward: chewing stimulates saliva production, and saliva naturally contains bicarbonate, which helps neutralize acid that has crept into the esophagus. The repeated swallowing also physically pushes acid back down into the stomach. It’s not a substitute for medication during a severe episode, but as a post-meal habit it can prevent heartburn from building in the first place.
Eating Habits That Prevent Flare-Ups
Stop eating at least three hours before you lie down. There’s a straightforward physical reason: when your stomach is full and you go horizontal, gravity can no longer help keep acid where it belongs. This single change eliminates nighttime heartburn for many people.
Smaller, more frequent meals also help. A large meal stretches the stomach and puts pressure on the valve between your stomach and esophagus, making it easier for acid to escape upward. Fatty meals are particularly problematic because they slow stomach emptying, keeping that pressure elevated for longer. You don’t need to eliminate any food category entirely, but paying attention to portion size at dinner makes a noticeable difference.
How You Sleep Matters
Two adjustments at bedtime can dramatically reduce nighttime heartburn. First, elevate the head of your bed by 6 to 8 inches using blocks under the bed frame or a foam wedge under the mattress. Stacking pillows doesn’t achieve the same effect because it bends your body at the waist rather than creating a gradual incline, which can actually increase abdominal pressure.
Second, sleep on your left side. The American Gastroenterological Association specifically recommends this position because of the way your stomach connects to your esophagus. When you lie on your left side, gravity and the natural anatomy of your digestive tract work together to keep acid pooled away from the opening to the esophagus. Sleeping on your right side does the opposite, making reflux worse.
Weight Loss and Long-Term Improvement
Carrying extra weight, especially around the midsection, increases pressure on the stomach and pushes acid upward. The good news is that even moderate weight loss makes a measurable difference. A 5 to 10 percent reduction in body weight in women has been shown to significantly reduce overall reflux symptom scores. In one large study, a BMI decrease of about 3.5 points over time cut the risk of frequent heartburn symptoms by nearly 40 percent.
This doesn’t mean you need to reach an ideal weight before you see improvement. The relationship between weight and reflux is dose-dependent: every pound lost reduces some of the mechanical pressure driving acid into your esophagus.
When Heartburn Isn’t Just Heartburn
Severe heartburn can feel alarmingly similar to a heart attack, and the overlap in symptoms is real. Heart attacks can present as nausea, indigestion, or a burning sensation in the chest. The distinguishing features of a cardiac event include pressure or squeezing pain that spreads to your neck, jaw, back, or arms, along with shortness of breath, cold sweat, sudden dizziness, or unusual fatigue.
If you have persistent chest pain and you’re not sure whether it’s heartburn, treat it as an emergency. Gallbladder problems can also mimic heartburn, typically showing up as intense, steady pain in the upper middle or right abdomen after a fatty meal, sometimes radiating to the shoulders or neck.
Heartburn that occurs more than twice a week, doesn’t respond to over-the-counter medications, or comes with difficulty swallowing or unintended weight loss is worth investigating further. At that frequency, occasional heartburn has likely crossed into gastroesophageal reflux disease, which benefits from a more structured treatment approach and sometimes requires evaluation of the esophagus itself.
