From few days i get white cotton type thing attached to my stool. what is that ?my stools are inconsistent , sometime hard and sometime fragmented?

Mucus: These are most likely mucus strands and your symptoms are consistent with irritable bowel syndrome in view of alternating loose and somewhat constipated stools. If you have further concerns, consult a gastroenterologist for evaluation,advice and treatment. In the meantime include adequate fluids and fiber in your diet and this could include daily metamucil.
