Digestion Problems. What should i do?

I am having problem of hyper acidity and I am taking medicines for that... I eat fruits for breakfast and dinner and have food at lunch.. I get burps and if u don't burp i don't feel fine in throat so I am taking medicines for that. Today I face an unusual observation when I went to the toilet i observed that colour of the stool was brownish red... In brown colour stool there where traces of red colour... What does that indicate? I have problems of hyper acidity now but it only burping problem... I don't feel any pain in stomach or other symptopms... I had done endoscopy two years back and it was normal... Today after the observation of stool i ak worried... What does the brownish red stool i.e brown stool with red colour traces indicate? What should I do???
