Several approaches reliably reduce heartburn and acid reflux, ranging from simple positioning changes to over-the-counter medications that work within minutes. The best strategy depends on whether you need fast relief right now or a longer-term plan to keep symptoms from returning. Most people benefit from combining a few lifestyle adjustments with the right type of medication for their pattern of symptoms.
Three Types of OTC Medications and How They Differ
Not all heartburn medications work the same way, and picking the right one depends on your timing. Antacids (like Tums or Rolaids) neutralize stomach acid directly and kick in within minutes, but their effects are short-lived. They’re best for occasional, predictable heartburn, like after a heavy meal.
H2 blockers (like famotidine, sold as Pepcid) take about an hour to work but last four to ten hours. They reduce the amount of acid your stomach produces rather than neutralizing what’s already there. If you know a meal is likely to cause trouble, taking one beforehand can prevent symptoms from starting.
Proton pump inhibitors, or PPIs (like omeprazole, sold as Prilosec), are the strongest option. They shut down acid production more completely, but they take one to four days to reach full effect. PPIs are designed for frequent heartburn, not the occasional flare. If you’re reaching for antacids more than twice a week, a short course of a PPI may be more effective. That said, long-term PPI use has been linked to reduced absorption of certain vitamins and minerals, lower bone density, and a higher risk of certain gut infections. If you’ve been on one for more than a few weeks, it’s worth revisiting whether you still need it.
Alginate Products: A Physical Barrier
Alginate-based products (like Gaviscon) work differently from standard antacids. When alginates mix with stomach acid, they form a gel-like raft that floats on top of your stomach contents. This raft acts as a physical barrier between your stomach acid and your esophagus, preventing acid from splashing upward. Standard antacids only neutralize acid that’s already there. Alginates are especially useful for reflux that happens when you lie down or bend over, since the barrier stays in place regardless of position.
Foods That Commonly Trigger Symptoms
Identifying your personal triggers is one of the most effective long-term strategies. While everyone’s tolerance is different, certain foods show up repeatedly as problems. Fatty foods sit in the stomach longer, which increases pressure and gives acid more opportunity to escape upward. Large portions of fried food are a double hit: high fat content plus stomach distension.
High-acid foods like tomatoes, citrus fruits, and vinegar-based dressings can irritate the esophagus directly, especially on an empty stomach. Chocolate contains caffeine and tends to relax the valve between the stomach and esophagus. Spicy foods, garlic, and raw onions are common culprits too. Peppermint, despite its reputation as a digestive soother, can actually relax that same valve and worsen reflux.
On the beverage side, caffeinated drinks (including decaf coffee, which still contains some acid-boosting compounds) increase stomach acid production. Alcohol relaxes the esophageal valve. Carbonated drinks bloat the stomach, pushing acid upward. If you’re trying to figure out your triggers, cutting these categories one at a time for a week or two and tracking symptoms is more useful than eliminating everything at once.
Sleep Position Makes a Measurable Difference
If your reflux is worst at night, how you sleep matters more than you might expect. The American Gastroenterological Association recommends sleeping on your left side. This works because of simple anatomy: when you’re on your left side, gravity and the natural curve of your stomach keep acid pooled away from the junction with your esophagus. Sleeping on your right side does the opposite, promoting acid flow into the esophagus and increasing reflux episodes.
Elevating the head of your bed by about six inches also helps. Propping yourself up with pillows alone doesn’t work as well, since it can bend your body at the waist and actually increase abdominal pressure. Placing blocks or a wedge under the head of the mattress keeps your entire torso on an incline. Avoiding food for two to three hours before bed gives your stomach time to empty, reducing the amount of acid available to reflux while you sleep.
Weight Loss and Reflux
Carrying extra weight around the midsection increases pressure on the stomach, which pushes acid upward. The connection between weight loss and symptom relief is well documented. In one large study, women who lost enough weight to reduce their BMI by about 3.5 points over time saw their risk of frequent reflux symptoms drop by nearly 40%. Other research found that a 5 to 10% reduction in body weight for women, and over 10% for men, led to significant improvements in overall symptom scores. For someone weighing 200 pounds, that’s a loss of 10 to 20 pounds. This isn’t a quick fix, but for people with persistent reflux, it’s one of the most effective long-term interventions.
Baking Soda for Quick Relief
Baking soda (sodium bicarbonate) is the simplest home antacid available. It neutralizes stomach acid on contact. The standard dose is half a teaspoon dissolved in a full glass of cold water, taken after meals, and you can repeat it every two hours if needed. Don’t exceed five teaspoons in a single day.
This is strictly a short-term fix. Don’t use baking soda for more than two weeks, and avoid it if you’re on a sodium-restricted diet, since it contains a large amount of sodium. It can also cause water retention, making it a poor choice for anyone with high blood pressure, kidney disease, or heart problems. Don’t take it within one to two hours of other medications, as it can interfere with absorption.
Ginger and Other Natural Options
Ginger has the most evidence behind it among herbal options for upper digestive symptoms. Its active compounds appear to speed up gastric emptying, meaning food moves out of your stomach faster, leaving less opportunity for acid to reflux. One clinical trial found that about 1,650 mg of ginger per day improved reflux-like symptoms and nausea, with most participants also showing improved stomach muscle activity. That said, research on ginger’s gastric emptying effects has been inconsistent across studies, so results vary from person to person. A cup of ginger tea or a small piece of fresh ginger after meals is a low-risk option worth trying.
Chamomile tea is widely recommended for digestive comfort, but clinical evidence specifically for acid reflux in adults is limited. It may help with general stomach discomfort and relaxation, which can indirectly reduce symptoms triggered by stress, but it’s not a targeted reflux treatment.
Warning Signs That Need Medical Attention
Occasional heartburn is common and manageable. But certain symptoms suggest something more serious is going on. Difficulty swallowing or pain while swallowing, unexplained weight loss, persistent vomiting, and loss of appetite all warrant a visit to your doctor. Vomit that contains blood or looks like coffee grounds, or stool that appears black and tarry, can indicate bleeding in the digestive tract. Chest pain that accompanies reflux symptoms should also be evaluated, since it can be difficult to distinguish heartburn from cardiac problems without testing.
