It's not always clear what causes solitary rectal ulcer syndrome. Doctors believe stress or injury to the rectum may cause rectal ulcers to form.
Examples of situations that could injure the rectum include:

- Constipation or impacted stool
- Straining during bowel movements
- Rectal prolapse, which occurs when the rectum protrudes from the anus
- Uncoordinated tightening of the pelvic floor muscles that slows blood flow to the rectum
- Attempts to manually remove impacted stool
- Intussusception, which occurs when part of the intestine slides inside another part
