Gastric bypass surgery changes the layout of the digestive system, which reduces the amount of food a patient can eat, according to the Mayo Clinic. Surgeons perform this surgery to reduce the risk of obesity related health issues in patients. Pre-op (pre-operation) procedures for gastric bypass surgery are focused on making sure the patient is physically and psychologically ready for this procedure.
Preparing for Surgery
Once your gastric bypass surgery date has been set, a doctor will conduct a chest x-ray and run blood work to ensure you're ready for surgery, according to Baylor College of Medicine. This usually takes place about a week before your surgery date.
When meeting with your surgeon, the surgeon will determine if you need medical approval from a specialist such as a cardiologist if you have other health issues. The doctor will also recommend lifestyle changes, such as starting or increasing physical activity, discontinuing any use of cigarettes and starting a low-fat and low-calorie diet, according to the Mayo Clinic. Making these changes before surgery will make the transition much easier.
Meeting with a Dietitian
Before surgery, you'll need to meet with a dietitian to discuss what to expect after surgery. Diet plays a large role in allowing the staples in your stomach to heal. After surgery, you'll consume clear liquids for the first few days. After those liquids are tolerated well, you can start introducing semi-solids, such as broth, juice without added sugar, milk and sugar free Jell-O.
Once your body tolerates semi-solids, you can introduce pureed foods, such as ground up lean cuts of meat, fish, egg whites, yogurt, soft vegetables and fruits, according to the Mayo Clinic. Soft solid foods (without pureeing) can be introduced a few weeks after surgery (cooked vegetables, soft meats, and fresh fruit).
A couple months after surgery, you can start consuming regular solid foods. However, avoid foods such as popcorn and dried fruits during this time, which are difficult for the stomach to digest because of their crunchy texture.
Meeting with a Psychologist
Before surgery a doctor will refer you to a psychologist for an evaluation. The psychologist will ensure that surgery is the best option and help you prepare for the benefits and risks of gastric bypass surgery. If the psychologist doesn't believe you are psychologically ready for surgery, it may be postponed.
