I underwent a subtotal gastrectomy in May 2012 for a 5,5cm GIST in my stomach. The diagnosis was T3 N0 M0. Low mitotic rate. I lost 11kgs and have been able to get only 3kgs back in 4 years. I am anemic and have to get my iron intravenously as no oral iron supplement works for me. I get a vit B12 shot every month and take vit d supplements monthly too as I have osteopenia.
