Acute abdomen refers to sudden, severe abdominal pain. Many times, it’s a sign of a medical emergency that requires immediate surgery. Inflammation, infections, hemorrhaging, blood flow blockages, obstructions and perforations can all cause acute abdomen.

Men and people assigned male at birth (AMAB) may have sudden pain due to testicular torsion.
People with a history of certain medical conditions can also develop acute abdominal pain.

Many different health conditions can cause acute abdomen. These causes may be surgical — meaning they likely require surgery — or nonsurgical.
Surgical acute abdomen causes include blood loss, infections, blood flow blockages, obstructions and perforations.
Hemorrhage is the loss of blood due to damaged blood vessels. Causes of hemorrhage include:
Various infections can cause acute abdomen, including:
Ischemia is when blood flow to a certain part of your body is reduced or restricted. Causes of ischemia include:
An obstruction is something that blocks food and liquid from moving through your digestive system correctly. Examples that cause acute abdomen include:
Perforations are holes that form in the walls of your body’s organs. Examples of perforations that can cause acute abdomen include:
Nonsurgical causes most likely don’t require surgery. Nonsurgical causes of acute abdomen include endocrine and metabolic disorders, hematologic disorders, and toxins or drugs.
These disorders involve the hormones, chemicals and glands of your endocrine system. Causes of acute abdomen may include:
Hematologic disorders are conditions involving your blood, blood cells, lymph nodes, bone marrow and platelets. Conditions that may cause acute abdomen include:

In addition, they’ll ask women and people AFAB whether they are or could be pregnant.
The provider will then perform a physical exam, focusing on your abdomen. They’ll examine the skin of your abdominal region and look for any external abnormalities. They’ll use a stethoscope to listen to your bowel sounds (auscultate). Then, the provider will gently touch (palpate) your entire abdominal area, looking for any tender areas or masses.
The location of your pain can help the provider make the correct diagnosis. For instance, you’ll usually feel acute diverticulitis pain in the lower left quadrant of your abdomen. But you typically feel cholecystitis pain in the upper right quadrant.
For gastrointestinal or prostate issues, the provider will likely perform a digital rectal exam. For gynecological issues, they’ll perform a pelvic exam. For a suspected testicular torsion, they’ll perform a testicular exam.
What your provider learns through the answers to their questions and your physical exam helps them narrow down the list of possible diagnoses. It could also add additional possibilities. Together, these factors will help them determine what, if any, diagnostic tests to order.
If your healthcare provider knows the cause of your acute abdomen symptoms, they may move immediately to surgery and not request any tests. However, if they aren’t sure of the exact cause, they may need tests to help make a diagnosis. Your provider will order different tests based on their findings during your physical exam. They’ll order specific tests based on what they suspect may be causing your acute abdomen.

Acute abdomen has many different possible causes, and most of them aren’t preventable. The best way to prevent acute abdomen is to lead a healthy lifestyle. That includes:

You should see a healthcare provider if you have ongoing (chronic) abdominal pain that lasts for weeks and/or doesn’t seem to be getting any better. Abdominal pain has many causes. A provider can help diagnose your condition and determine the correct treatment.
If you have sudden, severe abdominal pain, you should call 911, your local emergency services number or go to your nearest emergency room immediately. Your condition could be life-threatening if you don’t seek immediate treatment.
