The first day after surgery, you’ll drink clear liquids. By the time you leave the hospital, you can eat pureed foods and protein shakes and will continue to do so for about 4 weeks.
Keep in mind that you have to change the way you eat forever. After that first month, you’ll switch to eating soft solid foods very slowly. Other pointers to keep in mind:
After 2 or 3 months, you can move on to regular meals. But remember, you will not be able to eat as much as you used to. Sleeve weight loss surgery
A gastric sleeve surgery will dramatically reduce your calorie intake. You can eat normally but you will want much smaller portions during a meal. It can lead to dramatic weight loss in a relatively short period. In clinical studies, patients lost an average of 66% of their excess weight.
By weighing less, patients should also find it much easier to move around and carry out normal everyday activities.
As this surgery preserves the pylorus, the valve that regulates emptying of the stomach, it allows food to stay in the stomach for a while, making you feel full while the food trickles out.
There is no rearrangement of the bowel with a gastric sleeve surgery therefore dumping, which may occur to gastric bypass patients when their undigested stomach contents are “dumped” into their small intestine too quickly, should not a problem. Also, sleeve gastrectomy doesn’t affect the absorption of food, so nutritional deficiencies are less likely to occur⁴.
The part of your stomach that contains cells with an appetite prompting hormone, called ghrelin, has been removed during surgery, therefore, your hunger should be reduced in this procedure more than other weight loss surgical procedures such as gastric banding.
