how long does the surgery take for the gastric sleeve
A non-reversible procedure, gastric sleeve surgery is performed under general anesthesia and takes about one to two hours. Afterward you will probably stay in the hospital for one or two days; recovery from gastric sleeve surgery may last a few weeks. The abdomen is often swollen and sore for several days.
Most gastric sleeve patients lose up to 60% of their excess weight in a year and up to 70% of it in two years. Resolution of comorbidities occurs in just one to two years following weight loss surgery. One Swiss study learned that patients kept off at least 57% of their excess weight five years following their surgery.
