My aunt had gastric byp surgery and lost 96 lbs. a year later there was complications?

and the surgeon is going to remove her small stomach pouch, and do a gastric sleeve surgery. Her stomach that was left in her [but not attached] will be removed by 85% and shaped into a size of a medium banana and will hold about 4 to 5 ounces. My question is this, will she lose any more weight? Also, the part of her stomach that produces Ghrelin, the substance the triggers hunger, will be amputated also be removed. She will be on a full liquid diet for 6 weeks after surgery. Will the absence of Ghrelin help her to avoid eating for 6 weeks after surgery? Will the part of her stomach that produced Ghrelin ever grow back? The second surgery is not for weight loss, she had a severe complication that necessitated this extreme surgery. She has had bleeding ulcers and internal bleeding and if this doesnt work, they will have to completely remove her entire stomach. We just found out you can live without a stomach. Please no lectures or snide remarks as she is devastated and we are trying to get her through this.I might add this will be her 3rd surgery in 14 months and yes she has gotten a 2nd and even a 3rd opinion.
