Re: large,chunky stools
The more you look at and obsess about your stools the longer they will seem peculiar, trust me. As for the little bit of what appears to be blood, you most likely have a hemorrhoid or hemorrhoids.
I agree with the other poster, drink plenty of water, eat right, and my advice is to try NOT looking at your stools for a few days -- just flush and don't look. If you feel well otherwise and are eating right, I wouldn't worry at all.
Stools have a tendency to change from time to time and food, level of activity, and believe it or not, EMOTIONS, make a huge difference.
Try to ignore this for a few days, really. I think you'll see things back to what you perceive as normal when you've truly stopped obsessing.
I actually read in the Merck manual, a medical reference manual used by doctors, that "the best way to cure a stool that is "too thin or too green" is to stop looking at it!"
