Is 7+ litres colostomy output in 24 hours a record. I achieved this figure twice whilst in hospital last Autumn. Only one of the many many consultants had ever come across a larger output than mine. As well as the 7+ litres I also managed many 6l, 5l and 4l days too. Thankfully the output did eventually reduce to what it is now between about 1l and 2l a day - still high but not crazily high like it was!
