What causes cramping & an urgency to have a bowel movement immediately after eating?

Most times these symptoms represent a functional disorder such as ibs.

However other etiologies such as ibd, small intestine bacterial overgrowth, bile salt induced diarrhea (to name a few) can result in similar symptoms and in the right scenario should be further evaluated. So see your doctor. Would you like to video or text chat with me?

Sounds like irritable bowel or spastic colon.

Your doctor can prescribe medication for that like Bentyl (dicyclomine) to be taken before meals and at bedtime. Would you like to video or text chat with me?
