Thank you for the query.
Such strange stools can be called as a constipation
. The reasons of constipation can be medicines (antidepresants, Ca-blockers), thyroid disease
, inflammatory bowels disease, colon cancer
. Your diet should be helpful with constipation and if is not effective, you should rule out other possible reasons.
I suggest you to visit gastroenterologist, have physical examination, blood tests, thyroid tests, abdominal ultrasound. Colonoscopy
should be considered (especially if you are 50 or older).
Hope this will help.
