What Causes Black Coloured Bowels Along With Tiredness While On Benefiber?
Hi, The past 2 days I have had pastie black bowel movements. I do have a history of a bleeding ulcer, but do not think I have done anything to upset it. The only thing I have changed is that i have started using Benefiber 3x a day. I am also tiring easily and feel a bit lathargic. My BMI is 40 and I am in an area where the heat is near 100. I work in and out of the heat...not sure if the heat is affecting me?

Hello and thanks for posting. Black bowel movements are abnormal and can indicate active bleeding. Certain medications like iron can also also cause black stools but with the black stools and feeling of fatigue, please be evaluated today by a physician especially with your history of an ulcer. Benefiber is unlikely to be the reason for your symptoms. Lastly, make sure to always stay hydrated especially in the heat
