Risk Factors

Having any of the problems listed above will make the chances of pain in your belly higher.



The symptoms you have will depend on the cause. The most common are:

  • Persistent, severe pain, swelling, or tenderness in the upper, middle, or lower part of the belly
  • Guarding—involuntary contraction of the muscles in the belly
  • Rigidity—when muscles in the belly are tense and board-like
  • Fever


You will be asked for details about your pain. You will also be asked about other problems you may be having. A health history will be taken. You will be asked about any medicines you’ve taken. A physical exam will be done. This will involve checking the pelvis and rectum. You may also have:

  • Blood tests
  • Urine tests
  • Ultrasound
  • CT scan
  • X-rays
  • MRI scan
  • Exploratory laparotomy —to look for problems inside the belly



You may be given pain relievers. Talk to your doctor before you eat, drink, or take any medicine.

The cause of belly pain will need to be treated. Sometimes it's an emergency and surgery is needed right away.

Other methods may be with:

  • Medicines
  • Diet or lifestyle changes


Acute abdomen may not be preventable. It has many causes. If you're at high risk for problems, talk to your doctor.
