I had severe case of bloody diarrhea (mostly fresh blood without any stool without any pain at all) on 28, 29 and 30 April I had this for 8 to 9 times and then it stopped on third day just like it started, I took antibiotics for 7 days, My haemoglobin dropped from 14.5 to 8.2 in 5 days, for a while I felt dizziness, near fainting and weakness, I got blood transfusion one bag.
Its been over a month it didn't happen again and finally I have started to feel good again now hemoglobin is 10.8 and in recent stool test there is no blood or diarrhea.
I was asked to got colonoscopy done but since I'm too afraid so far I didn't get it done and still there is no sure diagnosis of what caused it.
One doctor said it was accute infection which stopped upon taking antibiotics and that I should monitor weight changes and get blood test done once a month to be sure.
I want to know what can cause this massive bleeding over 3 days with no prior experience of any sort of pain or fever or any other symptom.
5 months taking I was took whey protiens and pre workout supplements in high doseses for about 2 months and it immediately caused loss of appetite could that be linked to this problem?
