Initially, patients are not hungry after gastric bypass surgery. Initially, they have nausea, they lose their appetite, and that’s one of the mechanisms of which the operation works is decreasing the appetite the patient has. With time, the patient may develop an appetite again, but what happens is that the experience of eating is unpleasant and it reminds them again to stop eating, and therefore, they kind of lose their appetite because every time you do something that’s unpleasant, you kind of lose the desire to do it.
