What could be the cause of persistent blood in stool and low energy levels?

Hello doctor,

I am seeking assistance for my partner's current health condition. She has been experiencing blood in her stool for the past few weeks, accompanied by low energy levels. This is the third occurrence within the past year. She has a history of gastrointestinal (GI) problems, and anemia, and underwent a large intestine removal surgery seven years ago. Despite seeking medical help, including visits to the local hospital's emergency department and urgent care, we have yet to receive any results or a clear prognosis.

We are concerned about the lack of progress and the need for a comprehensive evaluation. We would greatly appreciate any advice on how to proceed in finding effective medical care and establishing a diagnosis.

Kindly help.

Thank you.
