Abdominal Pain Causes


Did you know abdominal pain was the most common reason for emergency department visits in 2018?1 Abdominal pain, also called stomach ache, is any discomfort felt in the stomach area. The pain can be acute, chronic, or progressive. It may present itself as a dull, sharp, colicky (happens at intervals) or achy pain. It can also be mild or severe. Abdominal pain may be accompanied by nausea, vomiting, diarrhoea, constipation, weight loss, jaundice, fever, indigestion, bloating, and bloody stool.

What is abdominal pain?

Abdominal pain is any discomfort felt in the abdomen. The abdomen is the space between your chest and pelvis. It is home to a number of organs in your body. Pain from the abdomen may come from any of the organs in your abdomen. The organs found in the abdomen are the liver, spleen, gallbladder, stomach, appendix, large intestine, small intestine, and uterus.

Abdominal pain is commonly called stomach ache, tummy ache, and belly ache.

Types of abdominal pain

There are 4 types of abdominal pain based on where you feel the pain.

Upper right abdominal pain 

This is pain that is felt in the upper right corner of your abdomen. Some common causes of upper right abdominal pain are liver diseases and gallstone diseases.

Upper left abdominal pain 

This is pain that is felt in the upper left corner of your abdomen. Some common causes of upper left abdominal pain are pancreatic disease and kidney infections.

Lower right abdominal pain 

This is pain that is felt in the lower right corner of your abdomen. A common cause of lower right abdominal pain is appendicitis.

Lower left abdominal pain

Abdominal pain can happen in 3 patterns. These are known as visceral pain, parietal pain, and referred pain.2

Visceral pain 

Originates from the internal organ. It is usually characterised by dull pain or ache felt in your abdomen. The pain also feels general, rather than from a specific area.

Parietal pain 

Is a sharp and focused kind of pain that happens when something irritates the lining of the walls of your abdomen.

Referred pain 

Is felt in a different part of the body than where the actual problem or injury happens. An example is shoulder pain in the inflammation of the gallbladder.

Abdominal pain can also be mild or severe. Please see a doctor immediately if you have any case of severe abdominal pain.

Causes of abdominal pain

Causes of abdominal pain can be acute, chronic, or progressive.

Acute abdominal pain usually lasts for some hours or days. It may also resolve on its own without the need for any treatment.

Chronic abdominal pain lasts longer, up to weeks, months, and even years. The pain may come and go at intervals or in episodes.

Progressive abdominal pain is the kind of pain that constantly gets worse with time.

Some causes of abdominal pain are also more common in certain age groups and sex. An example is period pain in those assigned females at birth.

Causes of acute abdominal pain

The cause of acute abdominal pain could be minor and resolve on its own, or it could be major which would require visiting A&E. If you feel a sudden excruciating pain in your abdomen, you should see a doctor immediately.

The following are some of the causes of acute abdominal pain:

  • Abdominal aortic aneurysm (AAA) - a condition where the main artery that carries blood from the heart gets weak and bulges
  • Appendicitis - inflammation of the appendix
  • Cholangitis - inflammation and infection of the bile ducts
  • Cholecystitis - inflammation of the gallbladder
  • Cystitis - inflammation of the bladder usually due to an infection
  • Diabetic ketoacidosis - a complication of diabetes characterised by ketones in the blood
  • Diverticulitis - inflammation of small pockets (diverticula) that form in your intestines

Causes of chronic abdominal pain

The causes of chronic abdominal pain can be hard to diagnose. The symptoms may come and go but don't get worse over time. 

The following are some of the causes of chronic abdominal pain:

  • Angina - a condition where your heart receives enough oxygen, often characterised by chest pain
  • Celiac disease - an autoimmune disorder that causes an immune reaction to gluten
  • Endometriosis - a condition where similar tissue lining of the uterus grows outside of the uterus
  • Functional dyspepsia - abdominal pain with no specific cause characterised by bloating and feeling full during and after meals
  • Gallstones
  • Gastritis - inflammation of the stomach’s lining

Causes of progressive abdominal pain

is abdominal pain that gets worse with time. They can develop from causes of chronic abdominal pain and may have symptoms not necessarily associated with typical abdominal pain.

Management and treatment for abdominal pain

Knowing the cause of your abdominal pain would determine the type of management and treatment you will need. Some causes of abdominal pain may resolve on its own with no treatment, but there are others that will require medication and even surgery.

Your doctor would administer the appropriate analgesic agent (pain relievers) by the appropriate route based on your condition. However, conditions like gallstones and appendicitis would require surgery.5

It is important you visit the hospital for proper diagnosis, treatment and management of your abdominal pain.


For an accurate diagnosis of the cause of your abdominal pain, your doctor needs to understand the pain well. They need to know where you feel the pain (its location), how the pain feels (character) when it started (onset), and the severity (intensity) of the abdominal pain.6

To do so, your doctor will check your health history and carry out a physical examination. They may also conduct some laboratory evaluation and imaging studies.7 The imaging studies could include a CT (computed tomography) scan, ultrasonography, and radiography. To further narrow your diagnosis, laboratory tests such as stool tests, urinalysis, urine culture, blood culture, enzyme markers, and liver function tests may be done.
