7 Ways To Calm Your Upset Stomach

Overview

An upset stomach is a general term for discomfort in your belly area. It can include feeling queasy, bloated, or having cramps. Most cases are mild and pass within a day or two.

Yes. Upset stomachs are one of the most common reasons people see a GP or go to a pharmacy for advice.

It can affect people of all ages. Some types of tummy trouble are more likely after rich meals or travel. Children and older adults may get dehydrated more easily if they also have vomiting or diarrhea.

Symptoms

Common symptoms

• Aching, cramping, or a feeling of fullness in your belly
• Nausea or feeling like you might vomit
• Bloating or passing gas
• Burping
• Indigestion or a burning feeling in your chest
• Loose motions or needing the toilet more often

Symptoms in children

• Fussiness or crying more than usual
• Clutching their tummy
• Feeling sick or being sick
• Loss of appetite
• Diarrhea or loose stools

Symptoms in older adults

• Loss of appetite or reduced thirst
• Dizziness or confusion, which may point to dehydration
• Less frequent urination or dark urine
• Abdominal pain that may be less typical than in younger adults

Causes

Main causes

• Viral or bacterial infections, often called stomach flu or food poisoning
• Eating too much, too quickly, or eating rich, fatty, or spicy foods
• Food intolerances, such as lactose or gluten sensitivity
• Heartburn or acid reflux
• Stress, anxiety, or tension
• Irritable bowel syndrome (IBS) or other digestive conditions
• Medicines that can irritate the stomach lining

Risk factors

• Eating food that hasn't been prepared or stored safely
• Traveling to areas with different food and water
• High levels of stress or worry
• Regular use of certain painkillers — talk to your doctor about this
• A history of digestive problems like IBS or reflux

When to see a doctor

See a doctor urgently if:

• You have pain that gets worse or wakes you from sleep
• You cannot keep fluids down and start showing signs of dehydration
• You see blood in your vomit or stool
• Your stomach is swollen, stiff, or painful to the touch
• You have recently had abdominal surgery or a hernia

Book a routine appointment if:

• Symptoms last more than 2–3 days
• You keep getting episodes of stomach upset
• You have unintentional weight loss
• You have difficulty swallowing or persistent heartburn
• You need advice because you are pregnant, older, or have a long-term condition

Diagnosis

A doctor or nurse will usually ask about your symptoms, what you have eaten recently, and any medicines you take. Most of the time, the diagnosis is based on this conversation and a brief physical exam.

Tests that may be done

• A simple examination of your abdomen (tummy)
• Blood tests to check for signs of infection or dehydration
• Stool tests if you have severe or long-lasting diarrhea
• Urine tests if the doctor suspects a urinary or metabolic cause

What to expect at your appointment

You will be asked to describe your pain and any other symptoms. The doctor may press gently on your tummy. You do not usually need special tests for a mild, short-lived upset stomach.

Treatment

Treatment depends on what is causing your symptoms. For most mild cases, the focus is on letting your stomach settle, replacing fluids, and slowly returning to normal eating. If an underlying condition is found, your healthcare provider will explain the best options for you.

Self-care at home

• Sip water or an oral rehydration drink little and often — ask your pharmacist which is right for you
• Rest your stomach by avoiding solid food for a few hours, then try bland foods like crackers, toast, rice, or bananas
• Avoid rich, spicy, or very sugary foods until you feel better
• Stay away from alcohol, caffeine, and fizzy drinks
• Apply a warm pad or hot water bottle wrapped in cloth to your belly for gentle relief
• Wash your hands regularly to avoid spreading infection

Medical treatments

Your healthcare provider may suggest medicines to control nausea, reduce acid, or treat an infection — if they think one is needed. Always ask your doctor, pharmacist, or nurse which product is appropriate for you, and never take more than the recommended amount.

When is surgery considered?

Surgery is rarely needed for an upset stomach. It may be necessary only if a more serious condition like appendicitis, a blockage, or a gallbladder problem is found.

Living with this condition

As your stomach recovers, go back to food slowly. Keep meals small and frequent. Keep a simple diary of what makes you feel better or worse — it can help you spot patterns.

Lifestyle tips

• Eat at regular times and don't rush your meals
• Manage stress with breathing exercises, light movement, or rest
• Avoid eating too close to bedtime
• Stay hydrated throughout the day
• Keep moving gently, but avoid intense exercise until symptoms settle

Diet and exercise

A plain, low-fat diet is easiest on the stomach while it settles. Once you feel better, slowly add your usual foods back. Gentle activity, like a short walk, can help get digestion moving, but rest is more important while symptoms are active.

Mental health and emotional wellbeing

Ongoing stomach problems can feel embarrassing, frustrating, and stressful. It is normal. Because the gut and brain are closely linked, anxiety can make symptoms worse, so look after your mental wellbeing too.

Prevention

You can reduce your chances of getting an upset stomach by handling food safely, washing your hands, and eating in moderation. You cannot prevent every episode, but healthy habits make them less likely.

Vaccines

There are vaccines for some infections that can cause stomach upset, such as rotavirus in babies. Your local vaccination schedule will explain what is recommended in your region.

Screening programmes

There is no routine screening test for a simple upset stomach. If you have a health condition that increases your risk, your healthcare provider will tell you about any relevant checks.

Complications

If left untreated

• Dehydration, especially in children, older adults, or people with long-term conditions
• Prolonged or severe diarrhea can lead to salt and mineral imbalances
• Missing a more serious condition, such as appendicitis, because symptoms were put down to an upset stomach

Long-term outlook

Almost all upset stomachs get better within a few days. Even when the cause is a stomach virus, the body usually fights it off with good hydration and rest. If an underlying condition is responsible, most digestive problems can be managed well with the right support and advice.
