I have noticed, in the morning, I get bulky stool followed by all soft/mushy stools! And at evening sometimes i get thin stools as showed in the picture... i get itching sometimes in my anal area. Can internal haemorrhoids cause thin stools? I am having bowel problems since the day I was treated for H pylori(last year December). It has been 7 months since then. Please guide me. Other history: no anemia, no blood in stools, no pain.
