Weight loss journey can be difficult for obese people. But with the help of surgery followed by a healthy diet and some physical workout, one can definitely achieve their weight loss goals. The surgeries related to weight loss are known as bariatric surgical procedures.
Weight loss by surgery is achieved by causing mal-absorption of nutrients, limiting the amount of food a stomach can hold or by a combination of both. The surgeries these days are done using advanced and minimally invasive techniques.
Some of the common bariatric surgeries include roux-en-y gastric bypass, mini gastric bypass, sleeve gastrectomy, duodenojejunal bypass and biliopancreatic diversion with duodenal switch.
Let us learn in detail about these procedures and which weight loss surgery would prove to be most effective?
In Roux-en Y gastric bypass, a small gastric pouch is created and some part of the small intestine is bypassed in a re-routing fashion, thereby restricting the food intake as well as causing mal-absorption of nutrients.
A small stomach means ingesting small amounts of food and fewer calories. This process also suppresses hunger, promotes satiety, and results in partial or complete resolution of type 2 diabetes. This weight loss surgery is considered as the gold standard. The results are long term and up to 80% of excess weight loss is promoted.
However, in order to maintain the ideal weight, an individual must lead a healthy lifestyle and be careful about what you eat. You must also follow up regularly with your surgeon and dietician.
Biliopancreatic Diversion with Duodenal Switch (BPD/DS) Gastric Bypass
This surgery is relatively complex and results in rapid weight loss due to malnutrition. The results at times are much more than even roux-en-y gastric bypass surgery. It controls blood sugar, lowers hunger pangs.
You may require higher doses of proteins and nutritional supplements after this procedure. Those that wish to undergo this weight loss surgery must be ready to spend more time in the hospital post-surgery because this surgery is a relatively complex one.
Adjustable Gastric Band
In this type of bariatric surgery, the surgeon uses an inflatable band. It is placed on the upper portion of the stomach to create a smaller pouch above it.
The size of the opening between the two portions of the stomach can be adjusted by filling the band with saline (sterile) that can be injected through a port under the skin. It is a reversible process.
It is less time consuming and a very easy process of weight loss surgery compared to the others. Although people have undergone weight loss after this procedure but the results are less than compared to weight loss in gastric bypass or BPD/DS.
These days the adjustable gastric band is virtually obsolete as people regain the weight as soon as the band is removed. Moreover, there are high chances of band erosion in case the band has been placed for a longer duration.
The surgeon will remove about 75% of the stomach of the individual undergoing this weight loss surgery. A very small tubular shaped or banana-shaped stomach remains after the surgery.
This surgery is gaining popularity among the newer surgeons as it is relatively easy to perform. There is a lesser incidence of malabsorption because the intestines are not bypassed. The process is irreversible, but the benefits are long-term.
All the bariatric surgeries mentioned above show great weight loss results. However, since everybody type of an individual, the weight loss goals and health conditions differ from person to person, the results may vary.
A medical professional expert in bariatric surgeries is the best person to decide which weight loss surgery will best suit your condition.
