Surgical Treatment:

Weight-loss surgery has proven to be a successful method for the treatment of morbid obesity. Today, there are multiple options for patients and surgeons to choose from based on their convenience thanks to the evolution of surgical principles. Some of the surgical procedures performed to treat obesity include:

  • Gastric banding
  • Sleeve gastrectomy
  • Roux-en-Y gastric bypass
  • Mini gastric bypass
  • Other novel procedures
  • Cosmetic procedures such as liposuction and tummy tuck

The use of laparoscopy for performing these procedures is the biggest advancement in bariatric surgery. The laparoscopic procedure is a minimally invasive procedure where the surgery is performed through small incisions. Patients experience minimal discomfort and rapid recovery with the process.
