The prevalence of obesity in the United States continues to be a problem. Pictured above is a self-reported map showing the percentage of obese individuals by state in the year 2014.  Weight loss surgery has become a viable option for weight loss of many obese individuals.  According to the American Society for Metabolic and Bariatric Surgery (ASMBS) 220,000 people had bariatric surgery in the United States in 2008.  This is compared to 16,000 procedures a year performed in the early 1990s.  With this huge increase in procedures, it seems that Americans are turning to surgery as an option for long-term weight loss. 

So what are the options available for weight-loss surgery? Some of the most common procedures listed by the American Society for Metabolic and Bariatric Surgery (ASMBS) are:

Gastric Bypass: This procedure consists of changing the course of the process of digestion. By rerouting the food, it limits the amount of food intake, helps with long-term weight loss, and is known to boost the amount of gut hormones which reduces overall hunger and increases the feeling of fullness.

Gastric bypass, ASMBS

Sleeve Gastrectomy: During this operation, about 80% of the stomach is removed, while the rest of the stomach is placed in a tubular pouch. This procedure is known to regulate the food intake the stomach can hold and also increases weight loss at >50% weight loss between 3-5 years.


Sleeve Gastronomy, ASMBS

Adjustable Gastric Band: This process a small stomach pouch is formed by an inflatable band which is positioned in the upper region of the stomach when this procedure is performed. The band encourages the feeling of fullness while decreases the feeling of hunger. Some benefits from this procedure are less calories are being consumed in the diet because of the decrease of food intake and this process is reversible and is flexible based on the conditions of the patients.


Lap Band System, FDA

Biliopancreatic Diversion with Duodenal Switch (BPD/DS): During this surgery, part of the stomach is removed forming a small stomach pouch and a bypass is performed to a large section of the small intestines. This decreases the amount of fat reabsorption by >70% and according to American Society for Metabolic and Bariatric Surgery (ASMBS) is the “most effective against diabetes”.



Electrical stimulation system:

This procedure received FDA approval in 2015.  It consists of an electrical stimulator being implanted into the abdomen.  There, it targets the vagus nerve with electrical pulses to block activity between the brain and stomach.  The direct mechanism in which this procedure performs is unknown.

Research shows that dietitians who have more knowledge on bariatric surgery, independent of their experience, can provide more practice recommendations.  So come broaden your knowledge on bariatric surgery with us!
