So 2 months back, i had constipation after that when constipation resolved i started getting thin stools. Then i saw once there was pinworms in my stool had medicines, slowly over a period of 2-3 weeks my stools got bulk. But the first bowel of the day has the bulk, then when i go in the evening or afternoon it's thin, why is this happening? I am worried if this is colon cancer :/. I dont smoke or drink, barely eat junk food, prefer home meals only and this year starting in jan/feb i had h pylori treatment 2 times. But its been 8-9 months already since theen. Please help me. Also when i sleep less, i find myself mildly constipated and get thin stools.. Also, can internal haemorrhoids cause thin stools? I don't have any bleeding. However in February i had a fissure. Which resolved on its own. Is this ibs or ibd or cancer symptoms, i am too scared
