6 Bariatric Surgery Procedures For Weight Loss

The obesity epidemic is at an all-time high. Not everyone finds it easy to lose weight in the traditional way; through exercise and sound nutrition. Therefore more and more are turning to weight loss surgery as their only way to reach a healthy weight. However, there are many limitations to this type of surgery, as it requires a referral by a healthcare expert, plus it poses dangers.

Bariatric surgery is the medical term for weight loss surgery and it is an available option for obese and morbidly obese persons, although it does require referral from a healthcare professional. Anyone considering bariatric surgery must be aware of the risks, as it is performed in a specialist center and requires long-term follow up care.

Obesity is linked to a wide number of health problems, including type-2 diabetes and heart trouble. Anyone with a body mass index (BMI) of 40 kg/m² or over can be referred for bariatric surgery and the National Institute for Clinical Excellence (NICE) has published clear guidelines on who is best suited toward bariatric surgery.

Adjustable Gastric Band

The surgeon makes several small incisions in the abdomen. The lights and camera lens on the laparoscope makes it easier to use the small instruments to guide the band around the upper half of the stomach. The band is circular and similar in size to a tiny inner tube. Under the skin lies a port, which is inflated with saline and causes restriction in the stomach. On consumption of food, the pouch fills up rapidly and food passes slowly through the slim opening into the lower part of the stomach. Altogether, the procedure often takes an hour and is reversible.

Roux-en-Y Gastric Bypass

The surgeon reduces the size of the stomach into a pouch the approximate size of an egg. This is done via use of a laparoscope, or by placing a large incision in the stomach. This pouch then connects to the jejunum (middle of the small intestine), which bypasses the duodenum and remaining stomach area to leave the patient feeling sated after only a small meal.

Vertical Sleeve Gastrectomy

The surgeon makes several small incisions in the abdomen and a laparoscope is used to reach the stomach area. The surgeon uses staples to adapt the stomach into a long thin tube and the remainder of the stomach is removed. The patient’s stomach is no longer able to consume high-fatty foods and one’s daily calorie intake significantly reduces. This creates considerable weight loss. This procedure takes approximately two hours and is non-reversible. 

Biliopancreatic Diversion Through a Duodenal Switch

This type of procedure is suited toward the morbidly obese with a body mass index (BMI) of over 60kg/m². It is a two-step process. Stage one of this surgery involves the removal of 70 percent of the stomach. The hunger hormone, ghrelin, is reduced, thereby reducing the appetite. During stage two, the surgeon switches the intestines so that digestive juices and food from the stomach travel on alternate paths and only meet at the base of the small intestine. The stomach is divided with only the outer margin removed, leaving a sheath of stomach and duodenum and pylorus at its end. The duodenum is separated to bypass bile and pancreatic drainage. The alimentary limb transports the food; the biliopancreatic limb transports bile and digestive juices, while the common channel is where the bilopancreatic and alimentary limbs join in the small intestine.

Gastric Stimulation

An implantable gastric stimulator is implanted beneath the abdomen where it then delivers electrical impulses to the stomach, initiating a feeling of satiety. This procedure is fully reversible.

Intragastric Balloon

A soft balloon is inserted through the mouth into the stomach using a slim flexible telescope called an endoscope. The balloon is expanded with saline solution, leaving the stomach partially restricted. It is often removed after several months. Anyone considering gastric banding or gastric bypass surgery may need to lose a lot of weight beforehand and this procedure may be utilized before the consideration of surgery. Researchers discovered that the subjects who underwent this procedure experienced no complications, even after the balloon collapsed and passed unnoticed through the colon. Weight loss was apparent when the balloons were inflated, but long-term evaluation of this procedure is not yet published.
