Laparoscopic gastric bypass (GBP) surgery is a surgical process that entails the formation of a gastric pocket. This procedure is done for significant and enduring weight loss in patients suffering from severe obesity. The Roux-en-Y gastric bypass (RYGB) is considered a gold standard within the medical fraternity. The procedure is certified by the National Institutes of Health and the American Society for Metabolic and Bariatric Surgery. The laparoscopic gastric bypass in India is a highly sought-after but costly procedure. On average, this procedure costs around INR Rs.2,93,000.
About the surgery
This weight loss process involves reducing the size of the stomach. Due to this reduction, the quantity of food intake at each meal is either limited or decreased. There are four main methods by which this surgery is done. These methods are:
- Gastric bypass
- Laparoscopic adjustable gastric band
- Biliopancreatic diversion with duodenal switch
- Sleeve gastrectomy (gastric sleeve)
Some of the most reputed and best bariatric surgeons in Delhi carry out GBP surgery. Most patients who undergo GBP surgery experience up to 65% weight loss after two years. Patients who undergo sleeve gastrectomy lose 56% of the weight, while nearly 49% of weight loss occurs with gastric banding. In general, the success rate of bariatric surgery ranges from around 50%-70%.
GBP surgery can be conducted as open surgery with a large incision on the abdomen to get to your stomach. It can also be conducted as a laparoscopic RYGB. The procedure of laparoscopic RYGB does not require you to stay in the hospital for long, and recovery happens quickly. In fact, with laparoscopic RYGB, you will experience less pain and suffer minor scars. It also significantly reduces the risk of infection or getting a hernia.
- Some studies suggest that after 10-14 years of surgery, 50%-60% of surplus body-weight loss is sustained by some patients.
- A year after GBP surgery, there is an average weight loss of 77% of surplus body-weight.
- A study conducted in 2000 reflected that 96% of particular physical conditions had improved after surgery. These conditions included:
- back pain,
- high blood pressure,
- sleep apnea,
- depression, and
- There could be a chance of chronic anemia occurring from Vitamin B12 deficiency. The solution to this is Vitamin B12 medication or injections.
- As the duodenum is circumvented, reduced absorption of iron and calcium occurs, leading to reduced total body iron. This might result in the condition of iron deficiency anemia. In some cases, chances of metabolic bone disease also occur. A balanced diet and vitamin supplements can treat these issues.
- Due to the quick draining of stomach contents into the small intestine, a condition called ‘dumping syndrome’ could occur. Consuming excessive sugar or large quantities of food could further trigger this condition.
People often struggle with losing weight using medication or continue gaining weight despite medication, alteration in diet, lifestyle modification, etc. Such individuals can opt for GBP surgery after consulting with their physician. Hospitals conducting laparoscopic gastric bypass in India are well-equipped with advanced medical instruments and techniques. Patients who have undergone a GBP surgery are discharged from the hospital in one or two days. For complete long-term recovery, rest and care must be taken for 2-5 weeks post-surgery.
