My sister is a 31 year old female. She has had very dark stool along with mucous in it for about a year. She has abdominal pain and has also been feeling very tired and run down.
Her Dr. ran a CBC on her and found that she is severely anemic. She also did a fecal test and found that there is blood in her stool. (She never sees bright red blood though. It is not visible to the eye, just very dark stool)
They did an upper bowel follow through, an endoscopy and a colonoscopy and they still have not found anything. Her Dr. said it didn't show Colitis, Crohns, Polyps, or Celiac's disease.
But she is still feeling very tired, constipated, is losing weight, very anemic, has stomach pain and mucous in her stool. They haven't done a second fecal test to check if there is still blood in her stool, but I am assuming there is because of the anemia.
They put her on prenatal vitamins for the anemia.
They are now going to do a capsule endoscopy to check more of her small intestine.
She had a fibroid removed from her uterus a year ago and that was her only recent surgery.
What should she do next? If she has cancer, do you think one of these tests would have found it by now? Could they have missed it?
What else could this be? Thank you.
