You will be seen by a dietician before, during and after your operation. You will have a total of 8 consultations before during and after your surgery with the dietician.

The Diet Program is completed in 22 weeks, but can vary amongst individuals depending on each patient’s compliance, progression and availability of appointments. The 22 week program is divided into two major parts: 12 Weeks before the operation and 10 Weeks after the operation. The dietician will also visit you while you are in hospital after you operation. During each of these sessions you will be counselled in detail regarding your diet and the necessary behavioural changes that will be required, before, during and after the operation.

It is of utmost importance to come to each dietary session as outlined in your program as you will be taught and counselled by the dietician on what to expect after surgery, how to change your eating habits and lifestyle before and after surgery to maintain the recommended weight loss and prevent possible nutrient deficiencies. You will also receive important information to prevent dietary complications after surgery. Education sessions will further include individual goal settings to suit your needs as well as the possibility of exercise programs. All these consultations aim to ensure optimal nutritional status at all times before, during and after your surgery with the ultimate goal to change your lifestyle to a healthy way of living.



The first twelve weeks before surgery is divided into two phases:
