You can't really. Also, I wouldn't really pay any mind to it. It's not really a sign of anything because it regenerates. I was always told that anyway.. Although it is kinda nice to have a sign that *something* is happening!
I lost parts at week 23 and again at week 28. The docs said it regenerates, so No worries because it didn't lead to anything else. I'll get excited when the water springs a leak
