Based on the information you provided, I have to say that this does not sound like a small bowel obstruction. A small bowel obstruction does not result in diarrhea. In fact, it usually results in little, if any, stool output of any kind because the obstruction prevents material from moving on to the colon to be released as stool. I recommend that you schedule an appointment with a gastroenterologist
. The typical symptoms of a small bowel obstruction are nausea and vomiting
and the inability to tolerate anything by mouth whether it be water or food. Small bowel obstructions are particularly common in people that have cancer that has metastasized to the abdomen and are also common in people that have had intra-abdominal surgery in the past. Your symptoms which include diarrhea, abdominal tenderness, and the sense of fullness are all symptoms that can be due to irritable bowel syndrome. While these symptoms are not typical for you, if you present it to a random physician with the symptoms and a previous history of irritable bowel syndrome, they would likely attribute it to this. Again, I would suggest that you schedule an appointment with the gastroenterologist for further workup of the symptoms. You might want to follow with one of these doctors
anyway in order to be treated properly for your IBS.
