Most heartburn and acid reflux improves with a combination of timed lifestyle changes and, when needed, the right type of over-the-counter medication. The burning sensation happens when stomach acid flows backward into your esophagus, irritating its lining. Fixing it usually means addressing why acid is escaping in the first place.
Why Acid Escapes Your Stomach
A ring of muscle where your esophagus meets your stomach, called the lower esophageal sphincter, normally stays contracted at a pressure of 15 to 30 mmHg to keep stomach contents where they belong. It relaxes when you swallow to let food through, then tightens again. The problem starts when this sphincter relaxes at the wrong time, a process called transient lower esophageal sphincter relaxation. These unscheduled relaxations are triggered by stomach distention (from large meals or gas) and are the primary mechanism behind reflux in most people.
Contrary to what you might assume, most people with mild to moderate reflux have normal sphincter pressure. The sphincter itself isn’t weak. It just opens when it shouldn’t. That’s why strategies that reduce stomach distention and pressure tend to work so well. A hiatal hernia, where part of the stomach pushes up through the diaphragm, can prevent the sphincter from closing completely and makes reflux significantly worse.
Fast-Acting Options for Right Now
If you’re dealing with heartburn at this moment, your fastest relief comes from antacids. These neutralize acid already in your esophagus and stomach within minutes. They wear off relatively quickly, but they handle the immediate burn.
H2 blockers (like famotidine) reduce acid production and keep gastric pH elevated for about four hours. They take 30 to 60 minutes to kick in, so they’re better as a preemptive step before a meal you know will trigger symptoms.
Proton pump inhibitors, or PPIs, are the most potent acid suppressors. They maintain a gastric pH above 4 for 15 to 22 hours daily, compared to just four hours with H2 blockers. But they have a short half-life of 30 minutes to two hours, and they work best when taken 30 minutes before a meal. PPIs are not designed for on-the-spot relief. They build up over days, reaching full effectiveness after consistent use.
A surprisingly simple trick: chew gum after a meal. Chewing stimulates saliva production to roughly 3 milliliters per minute, and saliva is naturally alkaline. It washes acid back down into the stomach and raises the pH in your esophagus. Bicarbonate gum pushes salivary pH up to about 8.0, but even regular gum helps.
Foods That Make Reflux Worse
Certain foods trigger reflux through specific mechanisms, not just because they’re “acidic” or “spicy.”
- High-fat meals directly reduce sphincter pressure and increase the time acid sits in your esophagus. Large, fatty meals are among the most reliably documented triggers.
- Carbonated drinks alter stomach acidity, increase gas (which distends the stomach and triggers sphincter relaxation), and often contain caffeine, sugar, or artificial sweeteners that further lower sphincter pressure.
- Citrus fruits reduce sphincter pressure and slow gastric emptying, keeping food in your stomach longer than usual.
- Spicy foods have more mixed evidence, but they appear to worsen reflux particularly in people who lie down after eating. The combination of spice and reclining is the real problem.
You don’t necessarily need to eliminate all of these permanently. Start by cutting them for two to three weeks, then reintroduce one at a time to identify your personal triggers. Most people find that two or three specific foods are responsible for the majority of their episodes.
Lifestyle Changes That Actually Work
Eat Earlier in the Evening
The interval between your last meal and lying down is one of the most powerful levers you can pull. Eating less than three hours before bed increases the odds of reflux by roughly 7.5 times compared to waiting four hours or more. Three hours is the minimum. Four is better.
Elevate the Head of Your Bed
Propping yourself up with regular pillows doesn’t work well because you tend to slide off or bend at the waist, which can increase abdominal pressure. Instead, raise the head of your bed by about 20 centimeters (8 inches), either with blocks under the bed legs or a wedge-shaped pillow that elevates at roughly a 20-degree angle. Clinical trials testing this approach used elevations of 20 to 28 centimeters and found meaningful symptom improvement over periods as short as two weeks.
Lose Weight Strategically
Excess abdominal weight increases pressure on the stomach, pushing acid upward. A prospective intervention trial found that losing 5 to 10 percent of body weight significantly reduced reflux symptoms in women, while men typically needed to lose 10 percent or more to see meaningful improvement. Waist circumference mattered too: women saw improvement after losing 5 to 10 centimeters around the waist, while men needed a reduction of 10 centimeters or more. Less than 5 percent weight loss produced no significant change for either group, so modest efforts need to be sustained to cross the threshold.
Smaller, More Frequent Meals
Large meals distend the stomach, which is the primary trigger for those unscheduled sphincter relaxations. Eating smaller portions more frequently keeps stomach volume lower and reduces the mechanical pressure that forces acid upward.
Home Remedies: What Works and What Doesn’t
Baking soda (sodium bicarbonate) dissolved in water does neutralize stomach acid and can provide short-term relief. Half a teaspoon in four ounces of water is a common dose. It works, but it’s high in sodium and shouldn’t be used regularly. It’s a stopgap, not a strategy.
Apple cider vinegar is widely promoted online, but the evidence behind it is thin. The few studies that exist are small, produced inconsistent results, and typically tested ACV as part of multi-ingredient formulations, making it impossible to tell whether the vinegar itself did anything. Adding acid to an acid problem also lacks a clear biological rationale. There’s no strong reason to reach for it over an antacid.
When Medication Becomes Necessary
If lifestyle changes and occasional antacids aren’t controlling your symptoms, a daily H2 blocker or PPI may be appropriate. PPIs are the more effective option, suppressing acid production for most of the day. For many people, a four-to-eight-week course resolves the issue, and they can taper off.
Long-term PPI use, however, carries real risks worth knowing about. Chronic use has been associated with reduced iron absorption (potentially leading to anemia), disrupted gut bacteria, increased susceptibility to intestinal infections including C. difficile, and the development of stomach polyps. Higher cumulative doses have been linked to precancerous changes in stomach tissue, with one large study showing a 32 percent increase in odds of gastric metaplasia at the highest dose levels. Some research has also connected prolonged use to increased risk of gastric and pancreatic cancers, though these are relatively rare outcomes.
None of this means you should avoid PPIs if you need them. It means they’re best used at the lowest effective dose for the shortest necessary time, not as a permanent substitute for the lifestyle changes that address the root cause.
Symptoms That Need Medical Attention
Most reflux is uncomfortable but manageable. Certain symptoms, however, signal something more serious. Difficulty swallowing, unintentional weight loss, persistent hoarseness, and heartburn that keeps getting worse despite treatment are all red flags that warrant evaluation. These can overlap with signs of esophageal cancer, Barrett’s esophagus, or strictures. Reflux that doesn’t respond to two weeks of a PPI, or that comes with chest pain or pressure, also deserves a closer look from a gastroenterologist.
