Hello and welcome to Healthcare Magic. Thanks for your query.
of the "reddish brown liquid" indicates bleeding from the upper gastro-intestinal tract. It could be due to stomach ulcers or due to an esophageal tear. Obviously, this is a serious matter of concern.
I would advise you to see a doctor at the earliest for a detailed examination and evaluation, so that further treatment can be planned. I would also suggest that you take professional help to handle your binge drinking
problem, as it can lead to even more dangerous health consequences, if not controlled.
Wish you all the best.
Dr. Jonas Sundarakumar
