This topic is about how often people with a colostomy change their ostomy appliances, specifically the wafer or flange, and how this affects the skin around the stoma. The person asking the question is curious about how long others go between changes and is looking for advice on maintaining healthy skin while managing their supplies efficiently.

Here are some insights and advice shared by others:

1. Change Frequency:
- Some people change their appliance daily and report healthy skin.
- Others change every other day, often rinsing the pouch with water and showering without the appliance on change days.
- A common schedule is twice a week, such as Tuesday/Friday or Monday/Thursday.
- Some manage a full week between changes, especially with less physical activity or using a two-piece system.
- A few can go 10-15 days by using specific products like skin prep, barrier rings, and elastic strips.

2. Two-Piece vs. One-Piece Systems:
- Two-piece systems allow changing the pouch without removing the wafer, which can save skin and reduce costs.
- Some find certain brands easier to use than others, with varying ease of snapping the pouch onto the flange.

3. Rinsing and Cleaning:
- Many people rinse their pouch with water at each emptying to keep it clean.
- Showering without the appliance on change days is recommended for skin health and is generally safe a few days after surgery.

4. Barrier Rings vs. Paste:
- Opinions vary: paste can mold well to irregular stomas but may be sticky, while barrier rings are often easier to handle and remove.
- Adhesive remover sprays or wipes can help remove residue with minimal skin irritation.

5. Skin-Friendly Removal and Edge Security:
- Using adhesive remover wipes or spray and waiting a bit before peeling can prevent the sensation of pulling off a scab.
- Elastic barrier strips can help if the wafer edges start lifting early.

6. Cost-Saving Resources:
- Some users have received free samples and supplies from ConvaTec's me+ program by calling their support line.

7. General Tips:
- Watch for changes in wafer color, as discoloration can indicate weakening adhesion.
- Heavy output, certain foods, and increased exercise might require more frequent changes.
- Consistent skin preparation and routine adjustments after heavy output days are important for maintaining healthy skin.
