This topic is about using Hegar dilators for ostomates, focusing on how often to use them and which lubricants are best. Here are some insights and advice shared by others:

- After buying a Hegar set from Amazon, one person used it at every pouch change for about six weeks. Despite this, their stoma opening narrowed from 12 mm to 9 mm over time. Dilation seems to only temporarily delay the narrowing because the abdominal wall naturally tries to close.

- For lubrication, a store-brand KY Jelly was found to work well.

- The narrowing of the stoma is due to the abdominal wall's healing response. Surgical widening can help, but sometimes changing the stoma's location or addressing tissue necrosis might be necessary.

Advice and insights from others include:

1. Instructions and Technique:
- A detailed guide for using anal and similar dilators can be found at Adler Micromed's website.

2. Lubricant Options:
- Aquagel water-based lubricating jelly is hospital-grade and safe for dilation and anal irrigation catheters. It's available on NHS prescription and labeled for professional use.
- Equate Lubricant Gel from Walmart is as effective as more expensive options but costs less.
- Generic or store-brand KY Jelly is also effective for stoma dilation.

3. Frequency and Results:
- Some have found success dilating at each pouch change, but even with this routine, the opening can still contract over time, so the relief may only be temporary.

4. Surgical and Anatomical Considerations:
- Tightening of the abdominal wall is normal, and long-term management might require surgical widening or relocating the stoma.
- Enlarging the fascial opening can increase the risk of a parastomal hernia, so patients may need to avoid strenuous core exercises like sit-ups after such a procedure.
