Most upset stomachs resolve within a few hours using a combination of simple dietary changes, natural remedies, and over-the-counter options. The right approach depends on what’s driving your symptoms, whether that’s nausea, bloating, cramping, or acid-related discomfort. Here’s what actually works and how to use each strategy effectively.
Start With What You Eat (and Don’t Eat)
When your stomach is already irritated, what you put into it matters more than anything else. Large meals, fatty foods, and high-fiber foods all slow down the rate at which your stomach empties, which can make nausea, bloating, and pain worse. Greasy or fried foods, whole grains, raw vegetables, nuts, seeds, and legumes are common culprits. Spicy foods and acidic drinks like coffee or citrus juice can further irritate an already inflamed stomach lining.
Instead, eat small amounts of bland, easy-to-digest foods. You’ve probably heard of the BRAT diet (bananas, rice, applesauce, toast), and it’s fine for a day or two. But as Harvard Health Publishing notes, there’s no research showing it works better than other bland options. Brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereal are equally gentle on your stomach. Once things settle, you can add cooked carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs. These foods are still easy to digest but provide the protein and nutrients your body needs to recover.
Sip water or clear fluids frequently in small amounts. Gulping large volumes of liquid at once can stretch the stomach and trigger more nausea. If you’ve been vomiting or having diarrhea, replacing lost electrolytes with a rehydration drink is more important than eating solid food right away.
Ginger and Peppermint: Two Remedies That Work
Ginger is one of the most reliable natural options for nausea and general stomach discomfort. It speeds up the rate at which food moves through your stomach and has direct anti-nausea effects. Fresh ginger tea (made by steeping sliced ginger root in hot water for 5 to 10 minutes), ginger chews, or ginger ale made with real ginger all deliver the active compounds. Aim for the equivalent of about one gram of ginger per day, roughly a half-inch piece of fresh root.
Peppermint works differently. It relaxes the smooth muscle in your gastrointestinal tract by blocking calcium channels in the gut wall, which reduces cramping and spasms. Peppermint tea is the gentlest way to use it for an upset stomach. Peppermint oil capsules are stronger and well-studied for conditions like irritable bowel syndrome, but they can worsen heartburn by relaxing the valve between your esophagus and stomach. If acid reflux is part of your problem, stick with ginger instead.
Chamomile Tea for Bloating and Spasms
Chamomile contains compounds that reduce inflammation in the digestive tract and act as natural muscle relaxants. Specifically, it inhibits the release of prostaglandins, chemical signals that cause digestive muscles to contract. By dialing down those contractions, chamomile can ease bloating, gas, and crampy abdominal pain. A warm cup of chamomile tea is a reasonable first step if your upset stomach involves a tight, gassy feeling rather than outright nausea.
Over-the-Counter Medications
If home remedies aren’t cutting it, a few pharmacy options target different symptoms:
- Antacids neutralize stomach acid directly and work best for heartburn or that burning feeling in your upper abdomen. They act within minutes but wear off relatively quickly, usually within an hour or two.
- Bismuth subsalicylate (the pink liquid or chewable tablets) is the most versatile option. It coats the esophagus and stomach lining, acting as a barrier against irritation. It helps with indigestion, heartburn, nausea, and diarrhea. For adults, the typical dose is two tablets or two tablespoons every 30 minutes to one hour as needed, but don’t exceed 16 tablets or 16 tablespoons of regular-strength liquid in 24 hours. Avoid it if you’re allergic to aspirin, since it contains a related compound.
- Simethicone breaks up gas bubbles in your digestive tract and is useful when bloating and trapped gas are the main issue. It doesn’t absorb into your body, so side effects are minimal.
Match the medication to your primary symptom. Antacids won’t help diarrhea, and anti-gas products won’t touch heartburn.
Try Acupressure for Nausea
Pressing on a specific point on your inner wrist, known as P6, can reduce mild nausea. To find it, place three fingers flat across the inside of your wrist, starting just below the crease where your hand meets your arm. The point sits in the groove between the two large tendons that run down the center of your wrist, just below where your three fingers end. Press firmly with your thumb for one to two minutes, then switch wrists.
This technique is the same principle behind anti-nausea wristbands sold for motion sickness and morning sickness. It won’t eliminate severe nausea, but it’s free, has no side effects, and can help take the edge off while other remedies kick in.
Other Quick Strategies
Heat can relax tight abdominal muscles and improve blood flow to your digestive organs. A heating pad or warm water bottle placed on your stomach for 15 to 20 minutes often eases cramping. Lying on your left side may also help, since this position uses gravity to assist the natural movement of food through your digestive system. Avoid lying flat on your back if acid reflux is involved; propping yourself up at a slight angle keeps stomach acid where it belongs.
Deep, slow breathing activates your body’s rest-and-digest response and can calm nausea that’s partly driven by stress or anxiety. Breathe in slowly through your nose for four counts, hold briefly, and exhale for six counts. Even two or three minutes of this can noticeably reduce that queasy, unsettled feeling.
When Stomach Pain Needs Medical Attention
Most upset stomachs are harmless and pass on their own. But certain patterns signal something more serious. The American College of Emergency Physicians advises seeking emergency care if abdominal pain is sudden, severe, or doesn’t ease within 30 minutes. Continuous severe pain accompanied by ongoing vomiting may indicate a life-threatening condition.
Pay attention to pain location. Severe pain in your lower right abdomen, especially with loss of appetite, nausea, vomiting, or fever, can indicate appendicitis. Pain in the middle upper abdomen that worsens after eating, lasts for days, or comes with a swollen tender belly and rapid pulse may point to pancreatitis. Bloody vomit, black or bloody stools, high fever, signs of dehydration (dizziness, very dark urine, inability to keep fluids down for more than 12 hours), or stomach symptoms that persist beyond 48 hours all warrant a call to your doctor or a trip to urgent care.
