Most belly aches are not serious and pass within a few days. A painful belly ache can also be the first sign of something that needs care the same day, and how much it hurts does not reliably tell you which kind you have. Check the warning signs first, then use the rest of this guide to see what may be going on and what to do next.
Get urgent help first if you have any of these signs
Call your local emergency number or go to the nearest emergency department if you have belly pain and any of the following:
- The pain came on suddenly and is sharp or severe.
- Your belly hurts when touched, or feels hard and rigid.
- You are vomiting blood, or your vomit looks like coffee grounds.
- Your stools are bloody, or black, sticky, and foul-smelling.
- You cannot pass stool or gas, especially if you are also vomiting.
- You cannot pass urine.
- You have chest pain, neck or shoulder pain, or trouble breathing.
- You have pain in or between your shoulder blades along with nausea.
- You have diabetes, and you are vomiting.
- You are currently being treated for cancer.
- You recently injured your belly.
- You have fainted, or someone with you has collapsed.
If you are pregnant or could be pregnant, do not wait to see whether the pain settles. Contact a doctor or urgent care service straight away.
Do not drive yourself to the hospital. Ask someone else to drive you or call an ambulance, and bring the medicines you take.
What a painful belly ache can mean?
Your belly runs from your chest to your groin, and pain there can come from many different organs. Where you feel it and how it behaves gives useful clues:
- Pain over more than half of the belly is more typical of a stomach virus, indigestion, or gas.
- Pain in one spot is more likely to come from a specific organ, such as the appendix, gallbladder or stomach.
- Cramping pain is usually not serious. It is often caused by gas and bloating and is often followed by diarrhoea.
- Pain that comes in waves, often severe and starting and stopping suddenly, is a common pattern with kidney stones and gallstones.
This table matches common patterns to common causes:
| What you notice | What may be behind it |
|---|---|
| Bloated, lots of wind | Trapped wind |
| Full and bloated after eating, heartburn, feeling sick | Indigestion |
| Cannot pass stool | Constipation |
| Watery stools, feeling sick, vomiting | Stomach bug or food poisoning |
| Ongoing cramps, bloating, diarrhoea and constipation | Irritable bowel syndrome (IBS) |
| Cramps around your period | Period pain |
| Sudden pain low on the right side | Appendicitis |
| Severe pain lasting hours in the middle of the belly or under the right ribs | Gallstones |
| Bad ongoing pain that can travel to the groin, with nausea and pain when passing urine | Kidney stones |
The table is a guide, not a diagnosis. Some serious conditions, including early appendicitis and colon cancer, can cause only mild pain or none at all. Doctors also consider causes such as ulcers, diverticulitis, pancreatitis, and inflammatory bowel disease, so pain that does not settle deserves a check even when the pattern looks harmless.
What you can do at home for mild pain
These steps are for mild pain when none of the warning signs above apply.
- Sip water or other clear fluids. Sports drinks are fine in small amounts.
- Skip solid food for the first few hours.
- If you have been vomiting, wait about six hours, then try small amounts of bland food such as rice, applesauce, or crackers. Avoid dairy.
- If the pain is high in your belly and comes after meals, an antacid may help, especially with heartburn or indigestion. Avoid citrus, tomato products, fried and fatty food, caffeine, alcohol and fizzy drinks.
- Ask a pharmacist what may be causing the pain and which treatments suit it. Check with a pharmacist or doctor before taking any medicine.
- If you have diabetes, check your blood sugar often. Vomiting with diabetes is an emergency, as listed above.
Home care is for easing mild pain, not for finding its cause, so watch how the pain changes over the next day or two.
When to see a doctor
Contact a doctor or an urgent advice service soon, even if none of the emergency signs apply, if:
- The pain is getting much worse, or has not improved after 24 to 48 hours.
- The pain is becoming more frequent and comes with nausea and vomiting.
- Mild pain lasts a week or longer, or keeps coming back.
- Bloating lasts more than two days.
- Diarrhoea has not cleared up after a few days.
- You have a fever along with the pain.
- It hurts or burns when you pass urine, or you suddenly need to pass urine more or less often.
- You have trouble swallowing food.
- You are losing weight without trying.
- Your appetite has been poor for a long time, or you cannot keep food or drink down.
- You have unusual vaginal bleeding or discharge.
If you are unsure whether your pain counts as mild, treat the warning signs as the line: any one of them means getting help now. Otherwise, ask a pharmacist or doctor rather than waiting, because being unsure and worried is reason enough to ask.
What to tell the doctor
A few details help the doctor find the cause faster:
- Where it hurts, whether it is all over or in one spot, and whether it spreads to your back, groin or legs.
- Whether it is sharp, cramping, constant or comes and goes, and whether it wakes you at night.
- When it started, and whether you have had similar pain before.
- What makes it better or worse, such as eating, a bowel movement, stress or an antacid.
- The medicines you take, any recent injury, and whether you might be pregnant.
- Any other symptoms, even ones that seem unrelated.
The doctor will examine your belly and may order tests such as blood, urine or stool tests, or imaging.
