Any operation or surgery performed for the purpose of reducing the weight of a person for medical purpose is called bariatric surgery or weight loss surgery.
Bariatric surgery is typically done only after you’ve tried to lose weight by improving your diet and exercise habits.

Bariatric surgery is done to help you lose excess weight and reduce your risk of potentially life-threatening weight-related health problems, including:

  • Heart disease and stroke
  • High blood pressure
  • Nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH)
  • Sleep apnea
  • Type 2 diabetes
While bariatric surgery can offer many benefits, all forms of weight-loss surgery are major procedures that can pose serious risks and side effects. Also, you must make permanent healthy changes to your diet and get regular exercise to help ensure the long-term success of bariatric surgery.

Surgeons qualified in the performance of the bariatric surgery are called ‘Bariatric Surgeon’, who performs this types of operation on regular basis.

After weight-loss surgery, you generally won’t be permitted to eat for one to two days so that your stomach and digestive system can heal. Then, you’ll follow a definite diet for a few weeks. The diet begins with liquids only, then progresses to pureed, very soft foods, and eventually to systematic foods. You may have many limitations or limits on how much and what you can eat and drink.

Gastric bypass and other bariatric surgeries can provide long-term weight loss. The amount of weight you lose depends on your type of surgery and your change in existence habits. It may be possible to lose half, or even more, of your excess weight within two years.
In addition to weight loss, gastric bypass surgery may progress or resolve conditions often related to being overweight, including:
  • Heart disease
  • High blood pressure
  • Obstructive sleep apnea
  • Type 2 diabetes
  • Nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH)
  • Gastroesophageal reflux disease (GERD)
  • Osteoarthritis (joint pain)
Gastric bypass surgery can also improve your capability to complete routine daily activities, which could help improve your quality of life.
