This topic is about dealing with a situation where you have stoma supplies that are not the right size for your current needs. Specifically, the supplies you have are pre-cut to a size that is smaller than your stoma, and you are wondering if it's safe to use them until you can get the correct size.

Here are some helpful tips and advice:

1. Understand the parts:
- The barrier or O-ring, which is a moldable seal, is elastic and can be gently stretched to fit the size of your stoma.
- The flange or wafer opening in a two-piece system is not elastic, so you will need to enlarge the hole if it is too small.

2. The safest approach is to enlarge the wafer opening using scissors or a stoma template. This ensures that the opening is large enough to fit around the stoma without squeezing it, which could restrict blood flow.

3. If you are using a moldable or stretchable barrier ring, make sure to stretch it to fit your stoma. Do not rely solely on the ring to make up for a wafer hole that is too small.

4. Whenever possible, opt for cut-to-fit wafers instead of pre-cut ones. This allows you to adjust the size as your stoma changes, especially after surgery.

5. While it is normal for a stoma to shrink over time, do not wait for this to happen if your current supplies are too small. Modify your appliance immediately to avoid any risk of injury.
