When dealing with an ostomy, it's important to pay attention to your body's signals. If you notice that there has been no output from your ostomy for five days, it's crucial to take action. Here are some steps you can consider:

1. If there has been absolutely no output, not even liquid, for five days, it's important to go to the Emergency Room immediately. This could be a sign of a serious issue that needs urgent attention.

2. Reach out to your doctor as soon as possible and follow their guidance. This can help prevent serious complications, such as an intestinal rupture.

3. Make sure to increase your overall fluid intake. Staying hydrated can sometimes help with ostomy output.

4. You might consider trying something to stimulate output. For example, drinking grape juice has been suggested by some as it acts as a mild small-bowel laxative.
