Most stomach discomfort, whether it’s nausea, bloating, cramping, or acid reflux, can be eased at home with a combination of simple remedies, the right foods, and a few physical adjustments. What works best depends on what’s causing the problem, so this guide covers the most effective strategies for the most common types of upset stomach.
Quick Relief With Heat and Positioning
One of the fastest ways to calm stomach pain is to apply a heating pad or hot water bottle to your abdomen. When heat above 40°C (104°F) reaches the skin near the source of internal pain, it activates heat receptors that block the chemical signals responsible for transmitting pain. Research from University College London found that these heat receptors directly shut down the pain receptors that fire when cells are damaged or distressed, which is why a warm compress works so well for cramps, bloating, and intestinal spasms.
Your body position matters too. If acid reflux or heartburn is part of the problem, stay upright after eating. Gravity alone helps keep stomach acid where it belongs. Lying down within a couple of hours of a meal makes it much easier for acid to creep into your esophagus. If you need to lie down, choose your left side. A study of 57 people with chronic heartburn found that while sleeping position didn’t change how often acid reflux occurred, acid cleared from the esophagus significantly faster when people lay on their left side compared to their back or right side.
What to Eat When Your Stomach Is Off
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a reasonable starting point for a day or two if you’re dealing with a stomach bug, food poisoning, or traveler’s diarrhea. But there’s no need to limit yourself to just those four foods. Brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereals are equally easy to digest.
Once your stomach starts settling, shift toward foods that are still bland but offer more nutrition: cooked squash, carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs. These give your body the protein and nutrients it needs to recover, which the classic BRAT foods largely lack. The key principle is to eat sparingly and slowly. A very full stomach increases the chance of reflux, so smaller, more frequent meals tend to sit better than three large ones.
Skip carbonated drinks. They make you burp, which pushes acid up into the esophagus and can worsen nausea or heartburn.
Staying Hydrated During Stomach Illness
If vomiting or diarrhea is involved, replacing lost fluids and electrolytes is the single most important thing you can do. Dehydration makes everything feel worse and slows recovery. Sip small amounts of clear liquids rather than gulping large quantities, especially if vomiting is a problem. Water, fruit juices, sports drinks, and broths all work for most adults. Even eating saltine crackers helps replace electrolytes.
For children, oral rehydration solutions like Pedialyte are the better choice because they contain a precise balance of glucose and electrolytes designed for smaller bodies. Older adults and anyone with a weakened immune system or severe diarrhea should also use these solutions rather than relying on water alone. Infants should continue breastfeeding or formula feeding as usual.
Ginger, Peppermint, and Chamomile
These three have the strongest track records for settling a stomach, and they each work differently.
Ginger is most effective for nausea. Clinical trials have used doses ranging from 250 mg to 2 g per day, split into three or four portions, and found that 1 g per day works just as well as 2 g. You can get this from ginger tea, ginger chews, or capsules. It’s generally well tolerated with no identified contraindications, though pregnant women should be cautious since data on fetal outcomes is limited.
Peppermint works best for cramping and bloating. The oil relaxes the smooth muscle lining your digestive tract by reducing calcium flow into muscle cells, which is what triggers contractions. Think of it as a natural antispasmodic. Peppermint tea is the gentlest way to try it. One caution: if your problem is acid reflux, peppermint can make it worse by relaxing the valve between your stomach and esophagus.
Chamomile tea is a good all-around option. Its anti-inflammatory properties help with nausea, gas, diarrhea, and general digestive irritation. It may also help lower stomach acid and inhibit the growth of bacteria linked to ulcers. A warm cup of chamomile is particularly useful when your stomach feels unsettled but you can’t pinpoint exactly what’s wrong.
Over-the-Counter Options
If home remedies aren’t enough, three categories of OTC medications target stomach issues in different ways:
- Antacids (Tums, Rolaids, Mylanta) neutralize existing stomach acid and work within minutes. They’re best for occasional, mild heartburn or indigestion that you want to knock out quickly.
- H2 blockers (Pepcid AC, Tagamet HB) reduce the amount of acid your stomach produces. They take longer to kick in but last several hours, making them useful when you expect discomfort to continue, like after a heavy meal.
- Proton pump inhibitors (Prilosec OTC, Nexium 24HR) also reduce acid production but are designed for frequent heartburn that occurs two or more days per week. They’re not meant for immediate relief. They take a day or more to reach full effect.
Choosing the right one comes down to timing. For right-now relief, grab an antacid. For longer-lasting or recurring issues, an H2 blocker or PPI is more appropriate.
Lifestyle Habits That Prevent Stomach Problems
If your stomach bothers you regularly, a few adjustments can reduce how often it happens. Excess body weight spreads the muscular structure supporting the valve at the top of your stomach, weakening the seal that keeps acid from rising. Losing even a modest amount of weight can noticeably improve chronic heartburn. Smoking has a similar effect: nicotine relaxes that same valve, making reflux more likely.
Eating smaller meals, staying upright for two to three hours after eating, and avoiding carbonated drinks are simple changes that compound over time. If nighttime heartburn is an issue, elevating the head of your bed by a few inches (rather than just stacking pillows, which can bend your body at the wrong angle) helps gravity keep acid down while you sleep.
Signs Your Stomach Needs More Than Home Care
Most stomach discomfort resolves on its own, but certain patterns warrant prompt attention. Pain that starts near your belly button and migrates to the lower right side of your abdomen, especially if it worsens over hours and comes with fever, nausea, or an inability to pass gas, follows the classic pattern of appendicitis. Severe, constant abdominal pain accompanied by a rapid pulse, nausea, and fever can signal pancreatitis.
Other red flags include pain so severe it disrupts your ability to function, vomiting that won’t stop and prevents you from keeping liquids down, and abdominal pain that feels similar to something you’ve experienced before but is notably more intense or different in character. If you’ve had prior abdominal surgery, new pain in the same area also warrants a call or visit, since adhesions or complications can develop months or years later.
