Most stomach aches respond well to simple remedies you already have at home: heat, ginger, peppermint, gentle hydration, and time. The right fix depends on what’s causing the pain, whether that’s gas, cramping, nausea, or an upset stomach from something you ate. Here’s what actually works and why.
Heat on Your Belly
A heating pad or warm water bottle placed on your abdomen is one of the fastest ways to ease cramping. Heat expands blood vessels in the area, increasing blood flow and helping tight muscles relax and stretch. This works for menstrual cramps, digestive spasms, and general abdominal discomfort. A warm (not hot) pad for 15 to 20 minutes is usually enough to notice relief. A warm bath does essentially the same thing if you don’t have a heating pad handy.
Ginger for Nausea and Slow Digestion
Ginger is genuinely effective, not just a folk remedy. It speeds up the rate at which your stomach empties its contents into the small intestine, which helps when food feels like it’s sitting in your stomach like a brick. In a clinical study, ginger cut gastric emptying time roughly in half compared to placebo (about 13 minutes versus 27 minutes) while also increasing the contractions that push food along.
You can use fresh ginger sliced into hot water as a tea, chew on crystallized ginger, or take ginger capsules. The study that showed measurable effects used 1,200 mg in capsule form, but even a strong ginger tea can help with mild nausea and bloating. Ginger ale from the store typically contains very little real ginger, so it’s not the best option.
Peppermint for Cramps and Spasms
Peppermint works as a natural muscle relaxant for your digestive tract. The active component blocks calcium from entering the smooth muscle cells that line your gut, which prevents them from contracting too hard. This is the same basic mechanism that prescription antispasmodic medications use. Peppermint tea is a good starting point for mild cramping. For more persistent pain, especially if you deal with irritable bowel syndrome, enteric-coated peppermint oil capsules deliver a more concentrated dose directly to the intestines.
One caution: peppermint can make acid reflux worse by relaxing the valve between your esophagus and stomach. If your stomach ache comes with heartburn or a burning sensation in your chest, skip the peppermint.
Staying Hydrated the Right Way
If your stomach ache involves vomiting or diarrhea, dehydration becomes the bigger concern. Plain water helps, but your intestines absorb water more efficiently when sodium and glucose are present together. That’s the science behind oral rehydration solutions like Pedialyte: glucose acts as a carrier that pulls sodium (and water along with it) through the intestinal wall faster than water alone.
Take small, frequent sips rather than gulping large amounts, which can trigger more nausea. If you don’t have a rehydration solution, diluted broth or a small amount of juice mixed with water and a pinch of salt works in a pinch.
What to Eat (and What to Skip)
The old advice to stick strictly to bananas, rice, applesauce, and toast (the BRAT diet) has fallen out of favor with pediatric gastroenterologists. Those foods are fine to include, but the diet is too low in calories, protein, and fat to sustain you for more than a meal or two. Current guidelines recommend returning to a normal, balanced diet as soon as you can tolerate it. Start with bland, easy foods and add variety as your stomach allows. Avoid greasy, spicy, or very sugary foods until you feel more settled.
If eating anything makes the pain worse, it’s okay to stick with clear liquids for a few hours. But don’t force yourself to fast for a full day; your gut actually recovers faster when it has some food to work with.
Over-the-Counter Options by Symptom
Different stomach aches call for different products, and choosing the wrong one won’t help much.
- Gas and bloating: Simethicone (found in Gas-X and similar products) works by lowering the surface tension of gas bubbles in your digestive tract, causing small bubbles to merge into larger ones that are easier to pass as burps or flatulence. It isn’t absorbed into your bloodstream, so side effects are minimal.
- Heartburn or acid-related pain: Antacids neutralize stomach acid quickly for short-term relief. If the pain recurs frequently, acid reducers that lower acid production provide longer-lasting results.
- Cramping and spasms: Antispasmodic products relax the muscles of the digestive tract. These work by blocking the nerve signals or calcium channels that trigger contractions.
- Nausea: Bismuth subsalicylate (Pepto-Bismol) coats the stomach lining and can calm nausea, though it’s not suitable for children or anyone allergic to aspirin.
The Pressure Point That Reduces Nausea
If your stomach ache comes with nausea, there’s a well-studied acupressure technique worth trying. The PC6 point (also called Neiguan) sits on the inside of your wrist, about three finger-widths below the base of your palm, between the two tendons. Press firmly with your thumb for two to three minutes.
A large Cochrane review covering more than 5,000 participants found that stimulating this point reduced nausea by about 32% and vomiting by 40% compared to sham treatment. The effect was comparable to standard anti-nausea medications. This is the same principle behind the anti-nausea wristbands sold in pharmacies, which apply constant pressure to this spot.
Probiotics for Recurring Pain
If stomach aches are a regular occurrence rather than a one-time event, probiotics may help over time. A meta-analysis of children with recurring abdominal pain found that one specific strain, Lactobacillus rhamnosus GG, significantly increased the likelihood of improvement, with a number needed to treat of just 4 for children with IBS. That means for every four children who took it, one experienced meaningful pain reduction who wouldn’t have otherwise. The effect was strongest for pain intensity rather than pain frequency. Probiotics aren’t a quick fix for today’s stomach ache, but they can shift the baseline if belly pain is a pattern.
When a Stomach Ache Needs Attention
Most stomach aches resolve within a few hours with rest and simple remedies. But certain patterns point to something that needs medical evaluation. Pain that’s located away from the belly button area (especially the lower right), pain that wakes you from sleep, unexplained weight loss, fever alongside abdominal pain, or tenderness when you press on the abdomen are all signs that something beyond a simple stomach ache may be going on. Pain that gets steadily worse over several hours, rather than coming and going in waves, also warrants a call to your doctor.
