Patient: I just noticed darkish blood when wiping after bowel movement.. What can it be?

Doctor: Hello,Welcome to ATD. Thank you for the query.It can be internal bleed in the gastrointestinal system, bleeding from haemorrhoids or bleeding from fissure.Kindly get a local examination done by a surgeon so as to determine the exact etiology.Do increase your fluid and fiber intake if constipation is also the problem along with it.Hope this helps. Take care.
