Hi i have bowel movements every other day when i use to go three times a day and when i go its dark green and sometimes it floats. ct hida scan normal?

Possible other cause: Have you changed your diet? Changes in consistency of BM can also be due to what we eat. Do you have any abdominal pain? If you got a CT HIDA I am assuming you are seeing a physician, and I would encourage you to advocate for further laboratory tests to make sure your pancreas is also healthy. Drink water, fruits/veggies, and decrease fat intake to see if this makes a difference as well.
