Abdominal pain

Date Updated: 07/10/2026

Definition

Everyone experiences abdominal pain from time to time. Other terms used to describe abdominal pain are stomachache, tummy ache, gut ache and bellyache. Abdominal pain can be mild or severe. It may be constant or come and go. Abdominal pain can be short-lived, also called acute. It also may happen over weeks, months or years, also known as chronic.

Call a healthcare professional right away if you have abdominal pain so bad that you can’t move without causing more pain. Also call if you can’t sit still or find a comfortable position.

Causes

Abdominal pain can have many causes. The most common causes usually aren’t serious, such as gas pains, indigestion or a pulled muscle. Other conditions may need medical attention right away.

The location and pattern of abdominal pain can provide important clues, but how long it lasts is especially useful when figuring out its cause.

Acute abdominal pain develops and often goes away over a few hours to a few days. Chronic abdominal pain may come and go. This type of pain may be present for weeks to months, or even years. Some chronic conditions cause progressive pain, which steadily gets worse over time.

Acute

Conditions that cause acute abdominal pain usually happen at the same time as other symptoms that develop over hours to days. Causes can range from minor conditions that go away without any treatment to serious medical emergencies, including:

Abdominal aortic aneurysm (when a blood vessel in the heart becomes enlarged)
Appendicitis
Cholangitis (which is inflammation of the bile duct)
Cholecystitis
Cystitis (which is inflammation of the bladder)
Diabetic ketoacidosis
Diverticulitis (which is inflammation of the digestive tract)
Duodenitis (which is inflammation of the top part of the small intestine)
Ectopic pregnancy
Fecal impaction (which is hardened stool that can’t be passed)
Heart attack
Injury
Intestinal obstruction
Intussusception (a condition in which part of the intestine slides into an adjacent part of the intestine)
Kidney infection
Kidney stones
Liver abscess (a pus-filled pocket in the liver)
Mesenteric ischemia (which is decreased blood flow to the intestines)
Mesenteric lymphadenitis (when lymph nodes in the folds of membrane that hold the abdominal organs in place swell)
Mesenteric thrombosis (a blood clot in a vein carrying blood away from your intestines)
Pancreatitis (which is inflammation of the pancreas)
Pericarditis (which is inflammation of the tissue around the heart)
Peritonitis (which is an infection of the abdominal lining)

Chronic (intermittent, or episodic)

The specific cause of chronic abdominal pain is often difficult to determine. Symptoms may range from mild to severe, coming and going but not necessarily getting worse over time. Conditions that may cause chronic abdominal pain include:

Angina (which is reduced blood flow to the heart)
Celiac disease
Endometriosis
Functional dyspepsia (which is recurring symptoms of an upset stomach)
Gallstones
Gastritis (which is inflammation of the stomach lining)

Peptic ulcer (which is an open sore on the lining of the stomach and upper small intestine)
Sickle cell anemia
Strained or pulled abdominal muscle
Ulcerative colitis

Progressive

Abdominal pain that steadily worsens over time is usually serious. This pain often leads to the development of other symptoms. Causes of progressive abdominal pain include:

Cancer
Crohn’s disease
Enlarged spleen (splenomegaly)
Gallbladder cancer
Hepatitis (which is inflammation of the liver)
Kidney cancer
Lead poisoning
Liver cancer
Non-Hodgkin lymphoma
Pancreatic cancer
Stomach cancer
Tubo-ovarian abscess (which is a pus-filled pocket involving a fallopian tube and an ovary)

When to see a doctor

Call 911 or emergency medical assistance

Seek help if your abdominal pain is severe and is associated with:

Trauma, such as an accident or injury.
Pressure or pain in your chest.

Seek immediate medical attention

Have someone drive you to urgent care or the emergency room if you have:

Severe pain.

Schedule a doctor’s visit

Make an appointment with a healthcare professional if your abdominal pain worries you or lasts more than a few days.

In the meantime, find ways to ease your pain. For instance, drink enough fluids and eat smaller meals if your pain is accompanied by indigestion. Avoid taking nonprescription pain relievers or laxatives unless directed by a healthcare professional.
