sometimes I have dark stools, recently it happened to me because I consumed black seeds but also some time ago it happened to me because I suffer from constipation and when I don't go out in the bathroom for a long time I have dark stools, occurs only once and then returns to normal color , I do not have vomiting or severe abdominal pain, what can it be, nor do I take any medicine, blood tests every time I do them, they turn out very well, once again it happened to me that my stool was half black and the other half was normal color but as far as I can remember I had consumed black seeds, idk
Take care from now....Drink colon cleansers don't ignore...It can be ibs coz it causes constipation and sometimes diarrhea.
I have symptoms of ibs, but for black stool I have no idea, as long as my blood tests have always been good
what did doctor said about it??
Also as you said black food causes black stool.
Sounds like hemorrhoids. You say you strain going to the bathroom. Well that causes them. You are bleeding because of them. Try taking stool softeners so going poo will be less strainful. Don't worry you aren't bleeding anywhere else. Tests that you've had would of shown bleeding from stomach or intestines. See a doctor about this. You will get great results.
