The symptoms you have tried to explain can be due to many different reasons ranging from the most serious to the most trivial ones. Hence instead of bothering about the diagnosis and do a lot of net self reading, its always better to proceed with the investigations one by one. The most common reason for the above said complaint could be a problem of piles and associated anemia
. This causes painless bleed and multiple bodily symptoms. One should also consider gastritis
and other acid peptic disease
. One this that you did not mention is whether you are already on some medications. Getting a colonoscopy
done is a good idea and will clarify many doubts for you. Stress
has not much to do with your passing of blood in stools and pain in abdomen.
Hope these things clarifies your doubts. Believe me, many times the problem is not as worse as we generally apprehend. Keep faith!
