Had my surgery in 2008. Spent my winters in Arizona, starting the month after my procedure. Couldn't find a local doc to see me for a fill. Went to sanding twice, but my husband became I'll and I couldn't leave him and his oxygen wouldn't last the trip. So my weight loss was sporatic. Then I gained 25 lbs. This last year, I've been very good about my nutrition. Down from 225 to 184, in 9 months. Problem is, three weeks ago, I had a UTI, and became nauseous and started vomiting. It's still happening and I can't pin point the problem. My port is quite prominent recently. Could there be a problem with my band?
