Ans: Intra-abdominal adhesions is the most common cause of small intestinal adhesions.

The most common cause is scar tissue from a previous surgery.

Small bowel obstructions can occur due to many reasons and the way to rule it out depends on your past medical and surgical histories. It can be due to prior abdomen surgeries causes adhesion, inflammatory Bowel disease, fecal impact/constipation, and abnormal growth in the bowel.

Most common cause is adhesions which usually develop if you have had abdominal surgery in the past or hernias (basically protrusion of loop of small vowel through a superficial weakening) which could get obstructed.

Constipation

#1 cause is adhesions, usually from prior GI surgery. Other causes include bowel strictures (from ulcers, NSAID use), inflammatory conditions like Crohn's disease, tumors.

Hi,

The most common cause of small bowel obstructions are adhesions. Those are scar tissue that forms usually due to prior surgery or infection. After that it is hernias, Crohn’s disease, malignancy, and volvulus, which is when the downstream part of the small envelopes the section of the bowel upstream of it.

All the best,
