Hello keepers51. It took a week or so for me to have output after my surgery, (Colostomy) in spite of the laxatives. After that I went to the stoma nurse and she poked around a bit. She said I had a blockage and she physically loosened it so that it passed through the stoma. I continued to have problems with hardened stools at the stoma end but, having been shown how to shift them I wasn't too worried. Nowadays, (years later) the output still hardens towards the stoma end and this (I believe) is down to the process of the liquid being absorbed through the colon walls more quickly there. My own problems have been resolved by irrigation (daily) However, it is now obvious that the stools are harder nearer to the stoma because the irrigation process expels the output in an order of hard- soft then liquid everyday.
I don't know if my re[ly is of any use to you in your own situation But I thought I would chip in anyway.
PLease note that I found my original solution via the stoma nurse.
Best wishes
Bill
