Most upset stomachs settle down within a few hours using a combination of simple home remedies, the right over-the-counter option, and a temporary change in what you eat and drink. The trick is matching your approach to what’s actually going on, whether that’s nausea, bloating, cramping, or acid-related burning.
What’s Actually Happening in Your Stomach
An upset stomach usually comes down to one of a few things: your stomach is producing too much acid, it’s not moving food along the way it should, or the nerves lining your gut are overreacting to normal digestive activity. Sometimes the stomach struggles to relax and expand when food arrives, which creates that uncomfortable fullness or pressure even after a small meal.
Your gut and brain are in constant communication, which is why stress, anxiety, and poor sleep can trigger stomach symptoms with no obvious physical cause. When doctors can’t find a structural problem, they often call it functional dyspepsia, a condition driven by miscommunication between your brain and digestive tract. This is worth knowing because it means calming your nervous system is sometimes just as effective as treating the stomach itself.
Ginger: The Best-Studied Natural Remedy
Ginger is one of the few natural remedies with solid clinical evidence behind it. The active compounds in ginger root block the same serotonin receptors that prescription anti-nausea medications target, which is why it works so well for queasiness. Ginger also speeds up the rate your stomach empties food into the small intestine, helping with that heavy, bloated feeling after eating.
You don’t need much. Clinical trials show benefits at doses of 1 gram per day or less, which is roughly half a teaspoon of ground ginger or a thumb-sized piece of fresh root. You can steep sliced fresh ginger in hot water for 5 to 10 minutes to make tea, chew on crystallized ginger, or take a ginger supplement capsule. The key is real ginger, not ginger-flavored products like most commercial ginger ales, which contain little to no actual ginger.
Simple Things You Can Do Right Now
Heat relaxes the smooth muscle in your digestive tract. A heating pad or warm water bottle placed on your upper abdomen for 15 to 20 minutes can noticeably reduce cramping and discomfort. If you don’t have a heating pad, a warm (not hot) towel works fine.
Sip clear fluids slowly rather than gulping water. Small, frequent sips of room-temperature water, diluted broth, or herbal tea keep you hydrated without overwhelming a sensitive stomach. Cold or carbonated drinks can sometimes make nausea worse.
Peppermint tea is another option with some evidence for easing bloating and gas. The menthol in peppermint relaxes the muscles of the digestive tract. Skip it if your main symptom is heartburn or acid reflux, though, since that same muscle relaxation can let acid creep back up into your esophagus.
Acupressure for Nausea
There’s a pressure point on your inner wrist called P-6 that’s been studied for nausea relief, including by major cancer centers like Memorial Sloan Kettering. To find it, hold your hand palm-up and place three fingers across your wrist just below where it bends. The point sits right below your index finger, between the two tendons running down your forearm. Press your thumb into that spot and move it in small circles for two to three minutes, then switch to the other wrist. It won’t cure food poisoning, but for mild nausea it’s free, safe, and worth trying while you wait for other remedies to kick in.
Over-the-Counter Options
If home remedies aren’t cutting it, the right OTC medication depends on your symptoms.
- Antacids (calcium carbonate products like Tums) neutralize stomach acid and work faster than any other option. They’re best for burning, sour stomach, or heartburn. Relief is quick but short-lived.
- H2 blockers (famotidine, sold as Pepcid) reduce acid production rather than just neutralizing what’s already there. They take about an hour to start working but last significantly longer than antacids. Good for acid-related discomfort you expect to linger.
- Bismuth subsalicylate (Pepto-Bismol) coats the stomach lining and is useful for nausea, diarrhea, and general queasiness. One important caution: it contains a compound related to aspirin. If you have a bleeding disorder, gout, or aspirin sensitivity, avoid it. Don’t combine it with other products that contain aspirin or salicylates, as the doses can add up to dangerous levels. It should never be given to children or teenagers who have or are recovering from the flu or chickenpox because of the risk of Reye’s syndrome.
What to Eat (and Avoid) While Recovering
Your stomach recovers faster when you give it less work to do. For the first several hours, stick to bland, low-fat, easy-to-digest foods. Plain rice, toast, bananas, and broth are classics for a reason. They provide calories and some electrolytes without requiring your stomach to churn through fat or fiber.
Avoid greasy, fried, or heavily spiced foods until you’re feeling better. Dairy can be hard to digest when your gut is irritated. Caffeine and alcohol both increase acid production and can worsen nausea. If eating anything sounds terrible, that’s fine. Focus on staying hydrated and eat when your appetite returns naturally. Small portions are easier on your system than a full meal, even once you feel ready to eat again.
Breathing and Body Position
Because your gut and brain are so tightly connected, calming your nervous system has a direct effect on digestive symptoms. Slow, deep breathing activates the branch of your nervous system responsible for “rest and digest” functions. Try breathing in for four counts, holding for four, and exhaling for six. Even two or three minutes of this can reduce the sensation of nausea and ease cramping.
If you’re lying down, prop yourself up at an angle rather than lying flat. A fully reclined position makes it easier for stomach acid to move toward your esophagus, which worsens heartburn and nausea. Lying on your left side can also help, since it keeps the junction between your stomach and esophagus above the level of stomach contents.
When an Upset Stomach Needs Medical Attention
Most stomach discomfort resolves on its own or with the strategies above. But certain symptoms signal something more serious. Get medical attention if you experience any of the following:
- Severe or sudden pain that feels like the worst you’ve ever had, especially if it wakes you from sleep
- Fever over 100.4°F (38°C) combined with abdominal pain
- Vomiting for more than 24 hours, or vomiting that looks green, black, or like coffee grounds
- Blood in your stool or vomit, including black or tar-like stools
- Chest pain, shortness of breath, or pain spreading to your arm, back, or jaw alongside stomach symptoms
- Yellowing of your skin or eyes, dark urine, or pale stools
- Pain that steadily worsens over hours or days rather than improving
Pregnant women with severe abdominal pain, especially with bleeding or dizziness, should seek care immediately. Adults over 60, people with weakened immune systems, and anyone with known liver, kidney, or bowel disease have a lower threshold for when stomach pain becomes concerning, so earlier evaluation is reasonable.
