You can relieve heartburn without Tums through a combination of dietary changes, sleep adjustments, over-the-counter alternatives, and simple habits that reduce acid from reaching your esophagus in the first place. Some of these approaches work within minutes, while others address the root cause so heartburn happens less often.
To understand why these strategies work, it helps to know what’s actually happening. At the bottom of your esophagus sits a ring of muscle that opens to let food into your stomach and closes to keep acid from coming back up. When that muscle relaxes at the wrong time or weakens over time, stomach acid splashes into your esophagus and causes that burning sensation. Everything below targets either strengthening that barrier, reducing the acid itself, or keeping acid away from it through positioning and timing.
Foods and Drinks That Make It Worse
Several common foods directly relax that muscle at the base of your esophagus, making reflux more likely. Coffee (even decaf) and caffeinated drinks are major culprits. Chocolate contains a compound similar to caffeine from the cocoa plant that has the same relaxing effect. Peppermint, garlic, onions, and alcohol all do the same thing in higher doses.
You don’t necessarily need to eliminate all of these permanently. Start by cutting the biggest offenders for two weeks and see if your symptoms improve. Many people find that one or two specific triggers are responsible for most of their episodes. Fatty and fried foods also slow stomach emptying, which increases the window for acid to push upward. Acidic foods like tomatoes and citrus don’t relax the muscle but can irritate an already-inflamed esophagus.
Meal Timing and Portion Size
Large meals increase the volume and pressure inside your stomach, pushing acid toward your esophagus. Eating smaller, more frequent meals reduces that pressure. Equally important is when you eat relative to when you lie down. Gravity helps keep acid in your stomach while you’re upright, so finishing your last meal at least two to three hours before bed gives your stomach time to empty before you’re horizontal.
Sleep Position Changes
Two simple adjustments at night can make a significant difference. First, elevate the head of your bed by about 20 centimeters (roughly 8 inches). A 2020 study found that people who raised their bed’s head by this amount had improved reflux symptoms compared to those who slept flat. You can use a foam wedge pillow or place blocks under the legs at the head of your bed. Stacking regular pillows doesn’t work as well because it bends your body at the waist instead of creating a gradual incline.
Second, sleep on your left side. Because of where your stomach sits in your body, lying on your left side positions the stomach below the esophagus, making it harder for acid to travel upward. Research from Amsterdam UMC confirmed that left-side sleeping reduces acid reflux episodes. Right-side sleeping does the opposite, placing the opening to your esophagus in a lower position relative to the pool of acid.
Chewing Gum After Meals
This one sounds almost too simple, but chewing sugar-free gum for 20 to 30 minutes after eating can help clear acid from your esophagus. Chewing stimulates saliva production, and saliva naturally contains bicarbonate, the same acid-neutralizing compound found in baking soda. The increased swallowing also helps push any refluxed acid back down. Avoid peppermint-flavored gum, though, since peppermint relaxes the esophageal muscle you’re trying to keep closed.
Baking Soda as a Quick Fix
If you need fast relief and don’t have antacids on hand, dissolving half a teaspoon of baking soda (sodium bicarbonate) in a full glass of water can neutralize stomach acid quickly. It works on the same principle as many commercial antacids. Take it one to two hours after meals.
This is strictly a short-term solution. Don’t use it for more than two weeks, and avoid it entirely if you have high blood pressure, heart failure, kidney disease, or are on a sodium-restricted diet. The sodium content is substantial, and regular use can disrupt your body’s acid-base balance. It’s also not appropriate for children under 12 or during pregnancy without medical guidance.
Over-the-Counter Alternatives to Antacids
If you’re looking for something more effective than Tums but still available without a prescription, two categories of medications work differently from antacids.
H2 blockers (like famotidine, sold as Pepcid) reduce the amount of acid your stomach produces. They take about an hour to kick in, which is slower than antacids, but their effects last four to ten hours. That makes them a better choice for preventing heartburn you know is coming, like before a meal that tends to trigger symptoms, or before bed.
Proton pump inhibitors (like omeprazole, sold as Prilosec OTC) are the strongest option. They block acid production more completely and are about 90% effective at healing esophageal irritation, compared to about 70% for H2 blockers. They take a few days of daily use to reach full effect and are designed for 14-day courses. They’re best suited for frequent heartburn rather than occasional episodes.
Weight Loss and Heartburn
Carrying extra weight, especially around your midsection, increases pressure on your stomach in the same way pregnancy does. That pressure pushes against the muscle at the base of your esophagus and makes reflux more likely. Losing even a moderate amount makes a measurable difference. One large study found that women who lost enough weight to lower their BMI by about 3.5 points reduced their risk of frequent reflux symptoms by nearly 40%. Another hospital-based study found that a 5 to 10% weight loss in women, and over 10% in men, led to significant drops in overall symptom scores.
This is obviously a longer-term strategy, but for people with recurring heartburn, it’s one of the most effective interventions available because it addresses a root cause rather than masking symptoms.
Other Habits Worth Changing
Tobacco smoke relaxes the esophageal muscle and triggers coughing, which can open it further. Quitting or reducing smoking often improves reflux on its own. Tight-fitting clothing around your waist and abdomen also increases pressure on your stomach, so looser fits can help.
Certain medications can contribute to reflux by relaxing that same muscle. These include some blood pressure medications (calcium channel blockers), common pain relievers like ibuprofen and aspirin, certain antidepressants, sedatives, and some asthma medications. If you take any of these regularly and have frequent heartburn, it’s worth discussing alternatives with whoever prescribed them. Don’t stop prescribed medications on your own, but knowing this connection exists gives you a useful conversation to have.
When Heartburn Signals Something More
Occasional heartburn is extremely common and usually manageable with the strategies above. But frequent heartburn, meaning two or more times per week for several weeks, may indicate gastroesophageal reflux disease (GERD), which benefits from a more structured treatment plan. Difficulty swallowing, unintentional weight loss, persistent vomiting, or chest pain that feels different from your usual heartburn are signs that something beyond simple reflux may be happening and warrant medical evaluation.
