Is A Weight Loss Procedure Right For You?

In the United States, more than 11 million people suffer from severe obesity and an estimated 93 million people are obese.  For many, obesity is a chronic condition that is very difficult to treat.

Altering the normal digestive process through bariatric surgery is a viable option. The expert surgeons at St. Vincent’s Medical Center offer three medical procedures:

What is the Normal Digestive Process?

Normally, as food moves through the digestive tract, appropriate digestive juices and enzymes absorb calories and nutrients. After being chewed and swallowed, the food moves down the esophagus to the stomach, where a strong acid continues the digestive process.

The stomach can hold about three pints of food at one time. When the stomach contents move through the pylorus to the duodenum, the first segment of the intestine, bile and pancreatic juice speed up digestion.

Most of the calcium and iron in the foods we eat is absorbed in the duodenum. The jejunum and ileum - the remaining two segments of the nearly 20 feet of small intestine - complete the absorption of almost all calories and nutrients.

The food particles that cannot be digested in the small intestine are stored in the large intestine until eliminated. 

How Does Bariatric Surgery Work?

Bariatric surgery is an option for clinically severe obese people. It promotes weight loss by restricting food intake or interrupting digestive processes.

Bariatric surgery is the standard of care when other medically supervised methods have failed. It offers the best option of long-term weight control for those with clinically severe obesity (defined by Body Mass Index, or BMI).

The bariatric surgeons at St. Vincent's Medical Center perform many types of weight-loss surgeries (see videos below). They use techniques that produce weight loss primarily by limiting how much the stomach can hold. All bariatric surgeries are done laparoscopically unless the open procedure is deemed necessary.
