Yes. After your surgery, you can only drink liquids for the first week or so. You can then slowly start to eat solid foods. Work with a nutritionist (a food expert) to learn how your diet should change. If you eat the wrong things, you could hurt your chances of losing weight or you might make yourself sick.
If you have gastric banding, for example, and don't chew your food enough, take large bites, or eat too fast, you could end up vomiting. If you have gastric bypass, and eat sugary foods after surgery, you could have another problem, called "dumping syndrome." Dumping syndrome makes you feel sick to your stomach, light-headed, and makes you shake, sweat, and turn red and feel hot, especially on your face. It can also cause diarrhea.
To avoid these problems and improve your chances of losing weight, you should:
●Eat slowly and chew your food well.
●Stop eating when you feel full. You will feel full much sooner than before the surgery because your stomach is so much smaller.
●Eat healthy foods that are high in protein and low in fat and calories.
●Avoid drinking and eating at the same time. Wait 30 minutes after you finish eating to drink water or other beverages.
●Avoid sugary foods.
●Avoid liquid foods that are high in calories, such as ice cream.
You might find that you dislike foods that you used to like, such as meat. You might also find that you like foods that you used to dislike, such as fruits and vegetables.
