Ibs grooves in stool

My niece noticed a groove in her stool. She went to her GP, who did a DRE and determined it was an internal hemorrhoid. She had no bleeding, pain, or mucus—just the groove in her stool.

She followed up with her GP since the groove hadn’t gone away. She had a consultation with a GI doctor.

We don’t have a family history of cancer and she’s still seeking answers for her symptoms.
