Change starts with the patient, as weight loss surgeries are a major factor for achieving the ideal weight; however, the patient should abide by the diet specified for each surgery type. The functional change in the digestive system requires simple foods at first, allowing the punctures to heal over time.
During the first year, the surgery is enough for weight loss, and the patient does not have to put much effort as long as he/she follows instructions.
Throughout the second year, the patient’s responsibility doubles. By the end of the third year, and after the stomach and intestines’ functions settle, the patient should maintain healthy habits to keep his/her weight from increasing.
Mainly, weight loss depends on the body mass index (BMI) before surgery, as well as committing to a healthy lifestyle. Most patients need to adhere to vitamin and mineral supplementation during the first months, and in some cases, it should last a lifetime.
