How to change a colostomy bag
Start by emptying your colostomy bag.
If there is urine or feces in your colostomy bag, it is important to empty these prior to changing the bag. The best place to do this is in the bathroom.
Options:
[1]. If you are a child, you might take your bag outside. If you are an adult, you might just clean it.
[2]. By emptying your bag, you will ensure your bag cannot be contaminated. It is important that you carry at least 1 or 3 pads of dry wipes at the bathroom.
[3]. As soon as your bag is emptied, leave the area with flushing water and toilet paper. Repeat this process with soap and water to get rid of a fresh layer of urine and feces.
[4]. Open the bottom of the bag over the toilet. For feces, you can gently squeeze it out of the bag; urine will automatically flow from the bag when it is opened.
