Fortunately, you can do five proactive things to prevent your stoma bag from leaking by changing your ostomy bag or pouch, checking the fit of the skin barrier, taking extra care of your skin, ensuring the ostomy pouch is secure during exercise, and being extra cautious when removing your ostomy skin barrier. Also, stool consistency and volume can lead to leaks causing problems like pancaking, a condition that causes sticky stool to block a portion of a stoma bag. You can help improve this problem by increasing your diet's fiber and staying hydrated.
