I suffer from lupus, thalassemia, two different hyper coagulation issues (both genetic), hoshimoto's, rheynaud syndrome, chronic -- and I do mean chronic constipation! It is not abnormal for me to go 13-17 days apart. I stay distended and live with my heating pad on my tummy! I've had 8 colonoscopies in the past two years. Found three polyps all at different times, were removed. All cytology comes back negative for any pathological abnormality. I take Linzess once a day (fairly new med). Still no improvement. I've had to remove impactions (thank God I went to nursing school), and no one seems concerned. I most recently passed a very large amount of well formed stool: however the stool was obviously dry, cracked, discolored and old. In all my life I've never seen anything look like this. It was almost completely covered in dark brown hair almost 1/3" long. From the beginning to the end! The stool was 17 days old. I can't get answers! That's not normal!! Help?!?!?
