An upset stomach usually clears up on its own within a few days. The fastest way to settle it is to eat small amounts of bland, low-fat foods like plain crackers, white rice, bananas, and applesauce, while sipping clear fluids like water or broth. For nausea and vomiting, the BRAT diet—bananas, rice, applesauce, and toast—remains the most widely recommended short-term approach because these foods are gentle on the digestive tract and easy to digest.
What Foods Actually Help an Upset Stomach?
Bland foods work because they are low in fiber and fat. That means your stomach does not have to work as hard to break them down. When your digestive system is irritated, giving it less work is the goal.
Foods that are generally well-tolerated include:
- Plain crackers or pretzels — they absorb stomach acid and settle nausea
- White rice or plain pasta — easy to digest and provides quick energy
- Bananas — they are soft and replace potassium lost through vomiting or diarrhea
- Applesauce — gentler than raw apple because the fiber is already broken down
- Plain toast or bread — no butter, no jam, just dry toast
- Broth or clear soups — replace fluids and sodium without taxing digestion
- Boiled potatoes without skin — starchy and bland
Mashed potatoes made with water or a little milk are also fine for most people. The key is to avoid fats, heavy sauces, and spices until your stomach feels normal again.
What Drinks Help When You Feel Sick?
Staying hydrated is the most important part of managing an upset stomach. When you vomit or have diarrhea, your body loses water and important minerals called electrolytes.
Clear fluids are the safest choice. Water is always fine. Broth, clear sports drinks, and oral rehydration solutions replace both fluids and electrolytes. Ginger tea is one of the few drinks with actual evidence behind it for nausea. Research has consistently shown that ginger can reduce nausea, particularly in pregnancy and after surgery, though the evidence for general stomach upset is less strong.
Peppermint tea is another option. Some studies suggest peppermint oil can help with symptoms of irritable bowel syndrome, and the tea form is generally harmless for most adults. If you have acid reflux, peppermint can sometimes make it worse because it relaxes the muscle between the stomach and esophagus.
Avoid dairy, caffeine, alcohol, and sugary drinks when your stomach is upset. Dairy can be hard to digest when your gut is inflamed. Caffeine and alcohol both irritate the stomach lining. Sugary drinks can pull water into the intestine and make diarrhea worse.
What Is the BRAT Diet and Does It Still Work?
The BRAT diet stands for bananas, rice, applesauce, and toast. It was the standard medical recommendation for decades. Pediatricians and family doctors still suggest it for short-term use, but there has been a shift in thinking.
The concern with the BRAT diet is that it is very low in protein, fat, and fiber. It does not give your body enough nutrition to recover fully if followed for more than a day or two. The current guidance from most medical organizations is to return to a normal, age-appropriate diet as soon as you can tolerate it.
That does not mean the BRAT foods are useless. They are excellent for the first 12 to 24 hours when you cannot keep much down. The problem is only when people stay on it for days and become malnourished.
A better approach is to use BRAT foods for the first day, then slowly add in other gentle foods like scrambled eggs, plain chicken, yogurt, and cooked vegetables. This gives your body the nutrients it needs to actually heal.
What Home Remedies Have Real Evidence Behind Them?
Ginger is the remedy with the strongest evidence. Studies have found that ginger can reduce nausea from motion sickness, pregnancy, and chemotherapy. For general stomach upset, many people find ginger tea or chewed crystallized ginger helps. The typical amount used in studies is about 1 gram of ginger per day, but no strict clinical guideline exists for over-the-counter use.
Chamomile tea is another traditional remedy with some supporting research. It has anti-inflammatory properties, and some studies suggest it can help with digestive discomfort. The evidence is not strong enough to call it a proven treatment, but it is safe for most people.
Heating pads or warm compresses on the abdomen can help with cramping. The heat relaxes the muscles of the intestinal wall, which can reduce pain. This is a physical effect, not a chemical one, and it is safe for most people.
One remedy to skip is activated charcoal. Despite claims on social media, no good evidence shows that activated charcoal helps with general upset stomach or food poisoning. It can interfere with medications and cause constipation.
Another popular claim is that apple cider vinegar settles the stomach. This is not supported by clinical evidence. In fact, drinking undiluted vinegar can irritate the throat and stomach lining further.
What Should You Avoid Eating When Your Stomach Is Upset?
Some foods make an upset stomach worse. Avoiding them can speed up your recovery.
- Fried and fatty foods — they slow stomach emptying and can worsen nausea
- Spicy foods — they irritate an already inflamed stomach lining
- Dairy products — temporary lactose intolerance is common after a stomach bug
- Caffeine — it increases stomach acid and can worsen diarrhea
- Alcohol — it irritates the stomach lining directly
- Raw vegetables and high-fiber foods — hard to digest when your gut is inflamed
- Citrus fruits and tomatoes — their acidity can aggravate an irritated stomach
This is especially important after a viral stomach bug. The infection temporarily damages the cells in your small intestine that produce lactase, the enzyme that digests lactose. That is why many people feel worse after drinking milk for a few days after being sick.
When Should You See a Doctor?
Most upset stomachs resolve on their own within 48 hours. But some symptoms require medical attention.
See a doctor if you experience any of the following:
- Vomiting that lasts more than 48 hours
- Blood in vomit or stool
- Signs of severe dehydration — dark urine, dizziness, dry mouth, or no urination for 8 hours
- Severe abdominal pain that does not ease
- Fever above 101.5°F (38.6°C)
- Stiff neck or severe headache along with vomiting
For children, the threshold is lower. Call a pediatrician if a child has vomited for more than 12 hours, has signs of dehydration, or has a fever above 100.4°F (38°C) if younger than 3 months. Infants under 3 months with any fever need immediate medical evaluation.
If you have an underlying condition like diabetes, kidney disease, or are pregnant, check with your doctor sooner rather than later. These conditions can make dehydration more dangerous.
Does the Cause of the Upset Stomach Change the Remedy?
Yes, it does. An upset stomach is a symptom, not a disease. The cause matters for choosing the right approach.
If you overate or ate something too rich, the best response is to stop eating and let your stomach empty. Small sips of water and a short walk can help. Antacids may help if heartburn is involved.
If you have a viral stomach bug, hydration is the priority. The illness needs to run its course. Bland foods can help, but you will not shorten the infection with any food or remedy.
If you have food poisoning from bacteria, the symptoms usually start within a few hours of eating the contaminated food. The treatment is the same — fluids and rest — but you should monitor more carefully because bacterial infections can cause more severe dehydration.
If you have acid reflux or gastritis, the approach is different. You want to eat small, frequent meals rather than fasting. Foods that are alkaline, like bananas and melons, can help neutralize stomach acid. Avoiding lying down for three hours after eating is also important.
If your stomach pain is from constipation, the opposite approach helps. Warm liquids, prune juice, and gentle movement can stimulate the bowels. High-fiber foods help here, which is why it is important to know what is causing your symptoms before choosing a remedy.
What About Over-the-Counter Medications?
Some medications can help with specific symptoms. But you should not take them all at once, and some can make things worse.
For diarrhea, loperamide (Imodium) can reduce the frequency of bowel movements. It works by slowing down the movement of the intestines. It is safe for most adults, but you should not take it if you have a fever or blood in your stool. Those signs suggest a bacterial infection, and stopping the diarrhea can keep the bacteria in your body longer.
For nausea, bismuth subsalicylate (Pepto-Bismol) is a common choice. It coats the stomach lining and reduces inflammation. It can help with mild nausea and diarrhea. It turns your stool and tongue black temporarily, which is harmless.
For acid-related upset, antacids like Tums or Rolaids neutralize stomach acid quickly. H2 blockers like famotidine (Pepcid) reduce acid production and last longer. These are appropriate if your upset stomach is mainly heartburn or indigestion.
Anti-nausea medications like ondansetron (Zofran) require a prescription. They are highly effective but are generally reserved for severe cases like chemotherapy-related nausea or hyperemesis in pregnancy.
Frequently Asked Questions
How long does an upset stomach usually last?
Most viral stomach bugs and mild food reactions clear up within 24 to 48 hours. If symptoms last longer than 48 hours, or if you cannot keep fluids down for more than 12 hours, seek medical advice.
Is it better to eat or fast when your stomach is upset?
For the first few hours, letting your stomach rest is usually best. After that, small amounts of bland food like crackers or toast are better than fasting because your body needs energy to recover.
Can ginger ale settle an upset stomach?
Real ginger can help with nausea, but most commercial ginger ales contain little to no actual ginger and are high in sugar, which can worsen diarrhea. Ginger tea made from fresh ginger root is a better option.
Does the BRAT diet still work for adults?
Yes, for the first 12 to 24 hours. The BRAT foods are gentle and easy to digest, but they lack protein and nutrients, so you should return to a more balanced diet as soon as you can tolerate it.
