Hi.
Thanks for your query.
Noted the history and understood the concerns.
Soft sticky stools with history of
amebiasis and history of
ulcerative colitis, cancer in family indicate that you needs thorough investigations.
I would suggest you the following:
Tests of stool for three consecutive days as this can give lots of information.
CT scan of abdomen helps to rule out inflammation of bowel,
diverticulitis, cancer, lymph nodes and many other diseases.
Colonoscopy and biopsy helps a lot for exact diagnosis.
If any disease is found, get it treated properly and you may get cured.
If all the investigations are normal or nonspecific, get treated as IBS that is
irritable bowel syndrome.
Identify the foods and beverages that instigate or enhance your problems and stop them.
Control of stress and anxiety may be the controlling factor.
