Abdominal adhesions (scar tissue inside the belly): the symptoms, a blocked intestine, the tests, and treatment
For anyone with belly pain that keeps coming back after abdominal surgery, even years later; anyone told they have adhesions, or whose scan showed nothing; anyone worried about a blocked intestine; and anyone about to have belly surgery. It passes on, by name, what the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, part of the NIH) says: what adhesions are, how common they are, who gets them, and the causes; the symptoms, a blocked intestine and when to get help right away, and infertility; the tests; treatment; and what surgeons do to lower the chance. It builds the words to say to your doctor, so you do not have to find them, and prints a card.
Right now
- Belly pain, and no gas, stool or fluids passing? Bloated and throwing up? NIDDK says these can be signs of a blocked intestine: seek medical attention right away; it can be life-threatening. NIDDK does not name 911. Ours: if you believe it is an emergency, call 911.
- Is it all too much, or is someone thinking of ending their life? Call or text 988, any hour (ours).

This page and its wording were written with AI (Claude) for Scarlet Beast (our AI policy). No doctor or nurse has reviewed it. The facts were read on October 19, 2026 on NIDDK’s (NIH) page Abdominal Adhesions (last reviewed June 2019) and its Spanish page Adherencias abdominales (last reviewed June 2019), which say the same. The numbers (more than 9 out of every 10 people who have surgery that opens the abdomen; a majority with no symptoms or complications) are NIDDK’s. Ours: when to call 911 (NIDDK says to seek medical attention right away, and does not name 911); 988; the questions to ask; the links to our other pages; and the order of the steps. What we left out: the section on clinical trials, the journal articles NIDDK cites, and NIDDK’s links to other sites. We name no medicine, no dose and no brand of barrier. Nothing you tick or type here is saved or sent.
