The purpose of this study is to find out whether the current method of calculating stomach volume using ultrasound is accurate in patients who have had a previous gastric sleeve procedure. This will help in determining whether ultrasound can be used to determine whether this population has fasted for long enough before surgery.
For each visit you decide to attend you will be asked to fast for 8 hours from food and 2 hours from fluids before you arrive (visits will likely be scheduled in the morning). At the visit your stomach will be quickly scanned with an ultrasound, you will be asked to drink a small volume of water, and scans will be completed every 30 minutes for 2 hours after the drink.
