Embarrassing question but what could cause green maybe green blue areas in my normal colored stool. no diet change. 3 days in a row.

See answer: The vast major of green and blue discolorations of one's stool are related to diet and not disease. Green (blue+yellow =green)poop can be seen with excess green leafy vegetables (chlorophyll), excess iron, artificial food dyes (ice cream, cake frosting, liquorice candy, etc). Less often by excess bile. Blue poop most often also related to food dyes (e.g. Blue curaçao, grape soda). Re-evaluate diet.

Something you swallo: Maybe a pill or candy. Maybe food. Relax.
