Bariatric surgery has recently emerged as a treatment option for obesity due to its effectiveness in managing this condition. Several studies concluded that reducing obesity through bariatric surgery lowers the risk of diabetes and cardiovascular diseases. However, bariatric surgery is not a 'quick-fix' method to treat obesity. It is just a process in the long journey for preventing weight gain.


It is critical to lead a healthy life and strictly follow all the instructions of the doctor to avoid weight gain and recurrence of medical conditions. In addition, patients must follow specific measures in daily life to ensure the best outcome from bariatric surgery.

The patient should make a goal of around 65 to 70 grams protein per day. Some of the eating tips that may be of help are:
