Gastric Bypass Surgery Pros and Cons

Gastric Bypass, otherwise known as Roux-en-Y Gastric Bypass is one of the treatments of obesity or morbid obesity.

The Gastric Bypass procedure is conducted by creating a small pouch in the upper part of the stomach and stapling it to reduce the size of the organ. Next, malabsortion of nutrients and calories is provoked by connecting the pouch to the second part of the small intestine. The cause of this surgery is to facilitate weight loss. The Gastric Bypass does not cause direct loss of weight. However, it includes life-style alterations, a healthy diet, and regular exercise.


  • Causes 60-80% weight loss
  • It is the most used method of bariatric surgery
  • It has the most success rate
  • Gastric Bypass alters the food course from passing through the small intestine to avoid the absorption of calories and nutrients.
  • It alters the gut hormones that promote satiety, suppresses hunger, and reverse one of the primary mechanisms that cause obesity-related type diabetes.
  • Improvements in overall health, comorbidities, mobility, and increase in energy expenditure and quality of life.


  • It is more complicated than the adjustable gastric band or laparoscopic sleeve gastrectomy, which may result in more complications than others.
  • It may lead to long-term vitamin or mineral deficiencies, particularly vitamin B12, iron, folate, and calcium.
  • Patients are subjected to life-long vitamin/mineral supplements.
