Yes, getting dietary advice is an essential part of care after gastric bypass treatment. A dietician will help you develop a diet plan that suits your needs and will teach you which foods to avoid or limit to prevent complications. In the first weeks after surgery, a liquid diet is usually recommended to allow the stomach to heal and prevent food from getting stuck in the surgical wound. Over time, you can gradually reintroduce solid foods, but it is important to eat small meals and chew slowly to avoid nausea or vomiting.
