This topic is about an ostomate who has been managing their ostomy for five years but is now facing sudden and severe leakage issues. This problem is causing skin irritation, a rapid depletion of supplies, and a significant impact on their quality of life. The person is seeking immediate solutions from the community to address these challenges. Here are some helpful suggestions and insights:

1. Identify recent changes and possible causes:
- Consider any recent weight changes, climate differences, increased activity, or alterations in your usual routine.
- Check if there are any defects in the latest batch of supplies that might affect adhesion.
- Ensure that the pouch and flange are completely snapped together, as an incomplete click can lead to leaks.

2. Optimize skin preparation:
- Thoroughly clean and dry the skin, then use Coloplast Ostomy Powder and a skin-barrier wipe like 3M Cavilon to create a protective crust. This can improve adhesion and reduce irritation.
- Allow any reddened skin to heal before expecting the usual wear time.

3. Evaluate equipment and configurations:
- Try a different pouching system, such as switching from a two-piece to a one-piece system, to see if it improves wear time.
- If there is a bulge or parastomal hernia, a flat flange may not fit well anymore. Consider using convex wafers and reinforcing with perimeter tape to better fit the body's contours.

4. Reinforce the seal:
- Use medical "pink tape" or paper surgical tape around the flange edge for added security. Alternate tapes to allow the skin to breathe.

5. Seek professional and manufacturer support:
- Contact the supply company’s product specialist for replacement samples, alternative system suggestions, and help with fit issues.
- Schedule an appointment with a wound-ostomy nurse (WOCN) to evaluate the stoma size, skin condition, and check for any hernias.
