Having been on holiday several times with “stammy stoma”, I’m well aware of the effects it can have. Most importantly I always ensure that I drink more water than I would back home. This is important for anyone but for someone with an ileostomy it is essential. Along with sweating more and stoma output, this can put us at serious risk of dehydration. I always know when I am a bit dehydrated as I just don’t feel right. I have in the past felt sick and shaky. I know then I have to take some time out of the sun and drink more water.
