PRINCIPLES OF BARIATRIC SURGERY
The basic principle of bariatric surgery is to restrict food intake and decrease the absorption of food in the stomach and intestines.
The digestion process begins in the mouth where food is chewed and mixed with saliva and other enzyme-containing secretions. The food then reaches the stomach where it is mixed with digestive juices and broken down so that nutrients and calories can be absorbed.
Digestion then becomes faster as food moves into the duodenum (first part of the small intestine) where it is mixed with bile and pancreatic juice.
Bariatric surgery is designed to alter or interrupt this digestion process so that food is not broken down and absorbed in the usual way.
A reduction in the amount of nutrients and calories absorbed enables patients to lose weight and decrease their risk for obesity-related health risks or disorders.
BODY MASS INDEX
Body mass index (BMI), a measure of height in relation to weight, is used to define levels of obesity and help determine whether bariatric intervention is required. Clinically severe obesity describes a BMI of over 40 kg/m2 or a BMI of over 35 kg/m2 in combination with severe health problems.
TYPES OF BARIATRIC SURGERY
There are various types of bariatric surgeries that can be performed. Today, most bariatric surgery is laparoscopic because compared with open surgery, it requires less extensive cuts, causes relatively minimal tissue damage, leads to fewer postoperative complications.
