Gastric bypass surgery causes surgical modifications to the stomach and digestive system that restrict the amount of food consumed and the number of nutrients absorbed, resulting in weight loss. As gastric bypass surgery is a metabolic surgery and not a cosmetic surgery, the weight loss is maintained. Gastric bypass surgery can provide new hope to patients who are dealing with morbid obesity and severe obesity-related complications. Gastric bypass surgery ensures about 40-80% excess weight loss and relief from severe co-morbidities.
Gastric bypass surgery is one of the available procedures for morbid obesity that continuously achieves and retains significant weight loss, reduces the incidence and severity of obesity-related co-morbidities and increases the general quality of life. Gastric bypass surgery is the oldest form of bariatric surgery which results in weight loss by modifying the natural process of digestion of the body.
Gastric bypass surgery is only suggested to patients who have been extremely unsuccessful in losing weight after trying all possible diets, exercises and strict changes in lifestyle. Gastric bypass surgery is considered as a last resort to ensure weight loss.
As gastric bypass surgery changes the entire digestive system, it is extremely necessary to be cautious while choosing this surgery. The benefits of gastric bypass are gratifying in the future; however, there are certain side-effects that need to be dealt with. As gastric bypass surgery restricts the intake of food by altering the process of digestion and also limits the nutrients absorbed by the body, therefore it is essential to follow a strict diet plan provided by the nutritionist.

Types of gastric bypass surgery
Gastric bypass surgery is the oldest form of bariatric surgery and is only suggested in cases where there is extreme obesity and severe co-morbidities. Gastric bypass surgery is both restrictive and malabsorptive form of metabolic surgery i.e. if not only reduces the size of the stomach to ensure lesser intake of food, but it also restricts on the quantity of fat absorbed by the body, thus resulting is weight loss.Gastric bypass surgery focuses on the restriction of food intake, selective malabsorption and restricting the patient’s food cravings or inclination for trigger food. The two main types of gastric bypass surgery procedures are as follows:
1. Roux-en-Y Gastric Bypass
This is the most commonly performed gastric bypass procedure and it is irreversible. This method of surgery reduces the amount of food consumed and also the quantity of the nutrients absorbed. A small pouch is created and the rest of the stomach is stapled. The new pouch created is the size of a walnut, and is directly connected to the small intestine. Therefore, the food consumed enters the small pouch and re-routes to the small intestine directly. This method drastically reduces the quantity of food that the patient can eat in a single sitting.
2. Biliopancreatic diversion with duodenal switch
This is another type of gastric bypass procedure which is more complex than the previous procedure and cuts off about 80% of the stomach. The operation bypasses most of the intestine by linking the bottom of the intestine to the near-stomach duodenum, hence the name ‘duodenal switch and biliopancreatic diversion’. This procedure restricts the amount of food intake and nutrients absorbed. This surgery is extremely effective with great results; however, it requires much more precaution and awareness. As this surgery results in severe malabsorption and vitamin deficiency, it is only limited to patients with a BMI greater than 50.
Gastric bypass surgery success rate
Gastric bypass surgery has the highest success rate with patients losing about 50-80% of their excess weight in a span on 12-24 months and being able to maintain the new weight. Undergoing surgery, however, is just one part of the beginning of the weight loss journey. To lose weight and to successfully maintain it requires lifetime commitment and discipline. The surgery does not provide a quick fix but requires utmost dedication to make necessary behavioural modifications, continuous adjustments in your diet, periodic workout, taking vitamins and supplements, and following other suggestions from the medical team.
