Gastric Sleeve Surgery
Gastric Sleeve Surgery is a permanent weight loss surgery that reduces the size of the stomach by as much as 85%. This restriction helps in two ways: first, the smaller stomach capacity contributes to making patients feel fuller faster – therefore reducing caloric intake. Secondly, the hunger hormone is reduced, allowing patients to be free of hunger desires.
Gastric Bypass Surgery
Gastric Bypass Surgery is a very powerful weight loss surgery that uses two surgical methods to achieve big weight loss for patients. Gastric Bypass uses restriction and malabsorption to reduce caloric intake severely. Gastric bypass is intended for patients who are suffering from co-morbidities, along with a very debilitating obesity.
