Hypoglycemia & Pituitary Tumor

Hi All, Anyone develop hypoglycemia after 2 years out? My stoma is stretched and I know it is part of the problem.  My Surgeon's office now has me testing for hypoglycemia.  I know that this has been happening for a while as when I eat a snack or something I feel better. I am waiting for my surgeon to put in for a lap band revision. I also have been diagnosed with a pituitary tumor and was wondering if anyone has had weight gain with this as well? Any suggestions or thoughts would be appreciated. Deanne
