If you're looking for a comfortable and wide hernia-prevention belt for a vertical ileostomy, you're not alone. Many people seek a supportive belt that can be worn during active tasks to help prevent parastomal hernias. The ideal belt should fit well with a vertically-worn ileostomy appliance, feel comfortable, and be available for purchase rather than requiring a DIY approach. Here are some helpful suggestions and insights:

1. The Omnigon Ostomy Support Belt from Australia is available for free on prescription there. You can check out their PDF catalogue online for more details.

2. Nu-Hope offers a range of ostomy hernia belts. You can view their full selection on their website. When ordering through supply dealers, make sure to specify the "Nu-Hope" brand.

3. Comfizz Ltd in the UK provides waistbands and unisex boxer garments designed for sports and swimming. These offer good abdominal support and help with hernia prevention. You can visit their website or contact them directly for more information. UK members can get these items on prescription and have even offered to mail extras abroad.

4. Hiline stoma support belts, also from the UK, are available for free on prescription. You can find their catalogue online.

5. The Celebration Ostomy Support Belt comes in 4" or 6" widths and includes a rigid plate that helps flatten existing hernias and supports a vertical bag. It's priced at $140 for the 6" version and can be ordered from their website.

6. OstomySecrets offers an elastic waistband along with men's and women's support underwear suitable for swimming and daily wear. You can explore their options on their website.

7. For those open to DIY solutions, some members suggest buying an elastic back-support belt from a drugstore or Walmart. Make sure it has no metal stays, cut a hole for the flange, and stitch or iron-bond the edges. This option costs under CA $40 and can work similarly to commercial belts.

8. Another DIY idea is to sew a custom band from swimsuit (lycra) fabric. You can make several widths for different activities like swimming, exercise, sleep, and intimacy.
