 [ Symptoms ] single white 14 seed shape on toilet paper after painful bowel movement what is it  i recently had a very painful bowel movement i have struggled with constipation since birth upon wiping there was a sesame shaped spot on my toilet paper but it was about 14 in length i have been eating sesame stix lately could it just be a bloated seed or could it be a parasite i crushed it between the toilet paper and it was waxygel like i have also been eating organic produce lately in which i found a tiny caterpillar on the celery some grapes had black chunks in them i didnt eat those [ Disease ] based solely on your description and the information in your posting i would guess that this was just an undigested seed many seeds will pass through the gi tract and emerge like this i do not think this was a parasite or have anything to do with that caterpillar on the celery i suspect this may be the list time you see these things unless of course you eat sesame seeds again
