Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. This may be r related to IBS andchronic constipation (spasms). That is particularly true when you consume foods like nuts or popcorn that would trigger spasms of the bowel. I suggest to run colonoscopy to exclude organic problems first. With regards to finding blood floating in the toilet after you pass the motion, that would be related to possible: - fissures due to chronic constipation - hemorrhoids. In both cases, you need to take measures to reduce constipation that would trigger such problems: - do more physical activity - increase water consumption - take more foods high in fiber content - fiber supplements can help - can use laxatives once in a while to improve the symptoms. Hope I have answered your query. Let me know if I can assist you further.
