Hello @mit and welcome to Mayo Connect. Yes, you are doing this right!

I am so glad to hear that your husband will be seen at Mayo later this month. We have a discussion group devoted to insulinoma. Here is the link, https://connect.mayoclinic.org/discussion/insulinoma-1/. You might be interested in reading the posts and having some information prior to your husband's visit.

What type of surgery did your husband have in March? Did your husband's current doctor refer him to Mayo or did you decide to do this on your own?
