these look like ropes but could be a type of parasite....when they detach they leave a gaping hole in the gut that can make you feel very ill for a few days..or even weeks....try vit c and salt every day until they stop coming out....I had them coming out for about 2 years...then I was clear... I was using a 1/4 tspn slat and vit c (ascorbic acid) 3x a day during this time...and also coffee enemas helps to get them out.... good luck...
