Sudden, complete blockage of the superior mesenteric artery causes severe abdominal pain, nausea and vomiting and is a medical emergency. Initially, most people with such a blockage vomit and feel an urgent need to have a bowel movement.

This is called ischemia – an inadequate blood supply (circulation) to an organ due to blockage of blood vessels in the area. Symptoms can include severe abdominal pain. If the blockage worsens, tissues in the intestine may start to die due to lack of blood flow.

How do you tell if your intestines are dying?

Signs and symptoms of acute intestinal ischemia typically include:

  1. Sudden abdominal pain that may be mild, moderate or severe.

Why do I feel a pulse in my stomach?

You’re most likely just feeling your pulse in your abdominal aorta. Your aorta is the main artery that carries blood from your heart to the rest of your body.
