Several things help with heartburn, ranging from fast-acting antacids that start working within minutes to simple changes in how you eat, sleep, and move. The right approach depends on whether you’re dealing with occasional discomfort or a recurring problem. Here’s what actually works and why.
Fast Relief: Antacids
Antacids are the quickest option for heartburn you’re feeling right now. They work by neutralizing the excess acid in your stomach, which raises the pH and reduces the burning sensation in your esophagus. Effervescent forms (powder dissolved in water) can start neutralizing acid in seconds, while chewable tablets typically take around 5 to 6 minutes to begin raising stomach pH. The trade-off is that relief is short-lived, generally lasting 20 to 60 minutes on an empty stomach and somewhat longer after a meal.
Common active ingredients include calcium carbonate (Tums), magnesium hydroxide (Milk of Magnesia), and aluminum hydroxide. These all do roughly the same thing through slightly different chemistry, but the practical differences are minor for occasional use. If you want the fastest possible relief, effervescent sodium bicarbonate products act almost immediately, though they contain significant sodium and aren’t suitable if you have high blood pressure, kidney disease, or are on a sodium-restricted diet.
Baking Soda as a Home Remedy
Plain baking soda (sodium bicarbonate) dissolved in cold water is an old standby that genuinely works. The typical dose is one to two and a half teaspoons in a glass of cold water after meals, with a maximum of five teaspoons per day. It neutralizes acid the same way commercial antacids do.
The catch is the sodium content. Baking soda is essentially pure sodium, so it can cause water retention and worsen conditions like high blood pressure, heart disease, kidney problems, and swelling in the legs or feet. It’s fine as an occasional fix, but it’s not something to rely on regularly.
Longer-Lasting Medications
If antacids wear off too quickly, two other categories of medication reduce acid production rather than just neutralizing what’s already there.
H2 blockers (famotidine, sold as Pepcid) reduce the amount of acid your stomach produces. They take longer to kick in, roughly 60 to 90 minutes, but the relief lasts for hours instead of minutes. For a mild, short-term problem, an H2 blocker is often the better choice over a stronger medication.
Proton pump inhibitors (omeprazole, lansoprazole, sold as Prilosec and Prevacid) are the most powerful acid-reducing option available without a prescription. They block acid production at the source, but they take several days to reach full effect. That makes them poorly suited for occasional heartburn. They’re designed for people dealing with frequent symptoms, typically two or more episodes per week. Gastroenterology guidelines recommend an 8-week course taken once daily before a meal for people with regular heartburn and regurgitation.
PPIs are effective, but long-term use carries real downsides. Chronic use is associated with deficiencies in magnesium, iron, vitamin B12, and calcium, because your body needs stomach acid to absorb these nutrients properly. There are also links to kidney problems, including chronic kidney disease, likely triggered by the drug accumulating in kidney tissue over time. Low magnesium levels from PPIs can further accelerate kidney damage by stressing blood vessels. None of this means PPIs are dangerous for a short course, but staying on them indefinitely without medical supervision isn’t ideal.
Foods and Drinks That Trigger Heartburn
Heartburn happens when the muscular valve between your esophagus and stomach (the lower esophageal sphincter) relaxes when it shouldn’t, letting acid splash upward. Certain foods directly weaken that valve. Fatty foods are among the worst offenders, because fat causes the valve’s pressure to drop, allowing acid to escape more easily. Chocolate and alcohol do the same thing. Smoking also lowers the valve’s resting pressure.
Other common triggers include citrus, tomato-based foods, spicy dishes, coffee, and carbonated drinks. These don’t necessarily weaken the valve but can irritate an already-sensitive esophagus or increase acid production. Keeping a mental note of which foods consistently cause your symptoms is more useful than following a generic avoidance list, since triggers vary from person to person.
Eating smaller meals helps too. A full stomach puts more pressure on the valve, making reflux more likely. Finishing your last meal at least two to three hours before lying down gives your stomach time to empty.
Sleep Position Matters
Heartburn that worsens at night or wakes you up responds well to two simple adjustments. First, sleep on your left side. The anatomy is straightforward: when you lie on your right side, your esophagus sits below your stomach, so acid flows toward it easily. On your left side, the esophagus sits above the stomach, and gravity works in your favor. A systematic review of the evidence confirmed that left-side sleeping consistently improves reflux symptoms.
Second, elevate the head of your bed. This doesn’t mean stacking pillows, which can bend your body at the waist and actually make things worse. Instead, raise the entire head end of the bed by about 6 to 8 inches using blocks, risers, or a wedge pillow that supports your upper body from the waist up.
Weight Loss and Heartburn
Excess weight, especially around the midsection, pushes up on the stomach and forces acid into the esophagus. Losing weight reliably reduces heartburn, but the amount matters. In a prospective study, losing less than 5% of body weight didn’t significantly change symptoms. Women saw meaningful improvement after losing 5 to 10% of their starting weight, while men needed a loss of 10% or more.
Waist circumference tells a similar story. Women experienced significant relief after losing 5 to 10 centimeters (about 2 to 4 inches) from their waist, while men needed a reduction of 10 centimeters or more. If you carry extra weight and deal with frequent heartburn, this is one of the most durable fixes available, because it addresses the mechanical cause rather than masking the symptom.
Signs That Heartburn Needs Medical Attention
Occasional heartburn after a big meal is normal. But certain symptoms alongside heartburn signal something more serious. Difficulty swallowing, feeling like food is stuck in your throat or chest, unexplained weight loss, vomiting, or signs of bleeding (dark stools, vomiting blood) all warrant prompt evaluation. Gastroenterology guidelines call these alarm symptoms, and they typically lead to an endoscopy to check for damage to the esophagus.
Even without alarm symptoms, heartburn that doesn’t respond to an 8-week trial of a proton pump inhibitor, or that returns every time you stop taking one, is a reason to get checked. Persistent acid exposure can change the cells lining your esophagus over time, and catching that early matters.
