Discharge from your colostomy can vary from a formed stool, pasty-like consistency or just liquid depending on where the stomas was fashioned in the large color; ascending, transverse, or descending. Some stomas can be controlled through irrigation; some can be managed with a closed-end pouch while others require the use of a drainable-style appliance,

There are no definite diet restrictions for colostomies, however some foods will cause excessive gas, such as broccoli, cabbage, eggs, fish, beans.  Other foods may be constipating and still others may produce odor while emptying.  Experiment with one food at a time so problem foods can be identified easily.
