How often does the appliance need changing?
Frequency of changes depends on many things, however, you must always change your ostomy appliance if you feel itching or burning from the skin surrounding your stoma.
Because an ileostomy bypasses the large intestine (where water is drained from the faeces to turn it solid), the output will be liquid. That means the pouch will need to be emptied typically 4-6 times a day (including once at night).
