Hi, I went to Mayo in Sept. of 2018, for a thyroid nodule. While I was there I told the internist I was having such weight gain because I had to eat or I thought I would pass out. Thank God, he sent me to a specialist in metabolism, she is an Endocrinologist. She listen to my story without judgement and ask all the right questions. She gave me a card for lab work if I started to feel one of my episodes ( thats what I named them ) now remember I have now been fasting for a thyroid biopsy ( our local hospital back home did one and had too much blood in the one they did so they wanted me to see a surgeon ) while I was on the table to get the biopsy one of the nurses told me that when I was done to go back to E 18 …I was a bit confused as I was fasting now for about 18 hours ( hard to do with an insulinoma ) when I walked back into her office …the first thing she ask me was how I felt. She ask me to sit down, then she told me that after our earlier conversation she called a fellow and discussed with him what she thought…he agreed with her that it sounded like insulinoma. But now I needed to either stay at Mayo or come back for the 72 hour test. I told he r I would come back in a couple weeks. When I went back the 72 hour test was to start in the Mayo Clinic through the lab in the endocrinology department….Blood drawn every hour, until noon then I would move to become an in patient at St. Mary’s. I was done just before noon , an never made it to the hospital. From there CT Scan & ESU were done, the tumor unfortunately was at the head about the size of a grape. It was full open surgery, 10 day stay, and some issues post op. All in all I feel I was well taken care of. I never heard the work insulinoma and really wasn’t sure where my pancreas was. I looked it up and knew from alll my symptoms that she was onto something. To me it was all a blessing, a gift from God.
