This topic is about dealing with frequent leaks from a Hollister one-piece ostomy appliance, especially when out in the summer heat. The person sharing their experience is from Australia and has an ileostomy due to Crohn’s disease. They notice that their appliance stays secure at home but tends to leak shortly after they leave the house, particularly in hot weather. This issue has affected their social life, and they suspect that body heat, tighter clothing, or sweat might be causing the problem. Here are some helpful tips and insights shared by others:

1. Try different systems and request free samples.
- Many people have found Hollister less reliable and have switched to other brands.
- Suggested alternatives include Coloplast Convexity 2-piece, Coloplast Convex Sensura Cut-to-Fit, Coloplast Shallow Base Plate, ConvaTec SurFit Flexible wafer and pouches, and Genairex Barrier Strips for added security.
- Contact manufacturers like Hollister, Coloplast, ConvaTec, and Genairex for trial kits.

2. Consider using convexity or shallow-base products if your stoma is flush, retracted, or if a skin crease appears when you bend.

3. Replace paste with barrier rings or strip paste.
- Many people report fewer leaks after switching from paste to barrier rings (Hollister or Coloplast) or to Coloplast strip paste.

4. Reinforce the wafer edge.
- Use 3M Transpore tape to tape completely around the wafer and re-tape before activities or showers.
- A stoma belt, like the Hollister belt, can help extend wear time.

5. Improve adhesion in heat and sweat.
- Use a skin-prep or barrier spray before applying the wafer.
- Warm the wafer with a hair-dryer before placing it on the skin, then press firmly for several minutes.

6. Prevent pancaking inside the pouch.
- Add a few drops of vegetable oil or baby oil into the bag to help the output slide down instead of piling up near the seal.

7. Be prepared for emergencies.
- Carry a pre-packed change kit, including a starter pouch, towels, extra clothes, tape, and toilet paper for quick fixes when away from home.

8. Consider additional adhesives and sprays.
- Hollister medical spray adhesive can provide extra grip for the wafer.
- Some users apply an ostomy-safe glue spray directly to the flange.

9. General experience notes.
- Leaking often decreases with practice and finding the right product match.
- Wear time can vary widely; some achieve 5–7 days or even up to 3 weeks with good tape or belt use, while others may need daily changes in hot weather.
- Always consult a stoma nurse to verify the cutting size and product choice.
