Most indigestion clears up within a few hours using simple changes: eating smaller portions, staying upright after meals, and avoiding foods that triggered the discomfort. If it keeps coming back, the fix depends on whether the cause is something you’re eating, how you’re eating, or an underlying issue like a bacterial infection in your stomach. Here’s what actually works, from immediate relief to longer-term solutions.
Quick Relief for Indigestion Right Now
If you’re dealing with that uncomfortable fullness, bloating, or burning after a meal, a few things can help in the short term. First, stay upright. Lying down lets stomach acid creep toward your esophagus, making things worse. If you’re going to sit, avoid slouching, which compresses your stomach.
Chewing sugar-free gum for about 30 minutes after eating stimulates saliva production. Saliva is naturally slightly alkaline, so swallowing more of it helps neutralize acid in your esophagus and wash it back down into your stomach. It’s a surprisingly effective trick for that burning, acidic type of indigestion.
Loose clothing helps too. A tight belt or waistband puts direct pressure on your stomach and can push its contents upward. Unbuttoning your pants after a big meal isn’t just a comfort move; it reduces physical pressure on your digestive system.
Baking soda (sodium bicarbonate) is one of the oldest home remedies and it does neutralize stomach acid quickly. The typical dose is one to two and a half teaspoons dissolved in a glass of cold water after meals, with a maximum of five teaspoons per day. But it’s high in sodium, so it’s not a good option if you have high blood pressure, heart disease, kidney problems, or any condition where fluid retention is a concern. It’s a one-off fix, not something to rely on regularly.
Breathing Techniques That Settle Your Stomach
This one sounds unlikely, but slow diaphragmatic breathing genuinely helps. Your diaphragm sits directly above your stomach, and when you breathe deeply into your belly rather than shallowly into your chest, it gently massages the upper digestive tract and activates the branch of your nervous system responsible for “rest and digest” mode. Clinical trials on diaphragmatic breathing for digestive disorders use protocols as simple as five minutes of practice per day.
To try it: sit or recline comfortably, place one hand on your chest and one on your belly, and breathe in slowly through your nose so that your belly rises while your chest stays mostly still. Exhale slowly through pursed lips. Even a few minutes of this after a meal can reduce that heavy, uncomfortable feeling, especially if stress or anxiety tends to make your digestion worse.
Eating Habits That Prevent Indigestion
What you eat matters, but how you eat often matters more. Eating too fast is one of the most common indigestion triggers because you swallow air and your stomach fills before it has time to signal fullness. Chewing thoroughly and putting your fork down between bites sounds basic, but it makes a real difference.
Smaller, more frequent meals reduce the workload on your stomach at any given time. A stomach stretched by a large meal produces more acid and takes longer to empty, both of which contribute to that bloated, uncomfortable feeling. If you tend to get indigestion after dinner, try making lunch your larger meal and keeping dinner lighter.
Common trigger foods include fatty or fried foods (which slow stomach emptying), spicy dishes, onions, citrus, tomato-based sauces, chocolate, coffee, and carbonated drinks. Alcohol and smoking both relax the muscular valve between your esophagus and stomach, letting acid escape upward. You don’t necessarily need to eliminate all of these permanently. Pay attention to which specific ones bother you and reduce those.
Timing matters as well. Eating within two to three hours of lying down is a reliable way to trigger symptoms. If nighttime indigestion is your issue, finish eating earlier in the evening.
Sleep Position and Nighttime Symptoms
If indigestion hits when you lie down, two adjustments help. Elevating the head of your bed by about six inches (using blocks under the bed frame, not just extra pillows) keeps gravity working in your favor all night. Pillows alone tend to bend you at the waist, which can actually increase abdominal pressure.
Sleeping on your left side also helps. In this position, your esophagus and its lower valve sit higher than your stomach, so acid drains away from the esophagus more quickly. Sleeping on your right side does the opposite, positioning the stomach above the esophageal opening and making reflux more likely.
Over-the-Counter Options
Antacids (the chewable tablets you find at any pharmacy) neutralize existing stomach acid and work within minutes, but they wear off in one to two hours. They’re fine for occasional use.
A step up from antacids are medications that reduce acid production. One type works within about 30 minutes and lasts around 12 hours, making it useful if you know a meal is likely to cause trouble. The other type takes one to four days to reach full effect but provides longer-lasting relief, which is better for persistent symptoms. Both are widely available without a prescription.
If you’ve been reaching for these regularly for more than two weeks, that’s a signal to look deeper into what’s causing the problem rather than just suppressing acid.
When Indigestion Keeps Coming Back
Chronic indigestion that doesn’t respond to diet changes and occasional antacids often has a treatable underlying cause. One of the most common is an infection with a bacterium called H. pylori, which lives in the stomach lining and causes inflammation. Testing is simple and noninvasive, typically a breath test or stool test, and treatment involves a short course of antibiotics. Current clinical guidelines recommend that anyone with persistent indigestion be tested for H. pylori before moving on to other treatments. If the test is negative, acid-suppressing medication is the standard next step.
Some medications cause indigestion as a side effect, particularly common pain relievers like ibuprofen and aspirin, certain antibiotics, and iron supplements. If your symptoms started around the same time as a new medication, that connection is worth exploring.
Stress plays a larger role than most people realize. The gut and brain communicate constantly, and chronic stress or anxiety can increase stomach acid production, slow digestion, and heighten your sensitivity to normal digestive sensations. For some people, managing stress through regular exercise, adequate sleep, or breathing exercises does more for their indigestion than any medication.
Symptoms That Need Medical Attention
Most indigestion is uncomfortable but harmless. A few specific symptoms, however, signal something more serious:
- Difficulty swallowing or the feeling that food is getting stuck
- Unintentional weight loss alongside digestive symptoms
- Blood in your stool (which can appear dark or tarry)
- Persistent nausea and vomiting
These are considered red-flag symptoms that typically warrant further investigation, such as an endoscopy. Guidelines from the British Society of Gastroenterology recommend urgent endoscopy for anyone 55 or older with dyspepsia and weight loss. For younger people without alarm symptoms, the test-and-treat approach for H. pylori is the recommended first step, with further evaluation reserved for symptoms that don’t respond to treatment.
