The epidemic of obesity has grown over the decade
and is now a worldwide public health problem. The
prevalence of obese patients has been increasing despite
many studies on obesity. There are many different
methods to manage obesity; diet, exercise, behavior
modification, weight loss program, pharmacotherapy and
surgery. However, there is an accumulating agreement on
bariatric surgery as being currently the most effective and
enduring treatment for severe obesity which usually cause
comorbidities such as diabetes, hypertension, sleep apnea
syndrome, non alcoholic fatty liver disease, depression etc.
Currently laparoscopic adjustable gastric band and
laparoscopic Roux en Y gastric bypass are the
predominant procedures for treatment of severe obesity.
The outcomes of surgical treatment for weight loss and
comorbidities along with complications of some surgical
procedures will be reviewed. The bariatric surgery patients
undergo many dramatic lifestyle changes and they feel
much better after the surgery in terms of activities and
recovery from comorbidities. Comparison of mortality rate
between surgery group and non-surgery group shows that
patients who have received surgery will have a ninefold
reduction in the risk of mortality.
Bariatric surgery has been evolving in terms of
instruments and techniques. The studies have contributed
to the understanding of the mechanism and physiology of
its effectiveness and complications.
In Korea, obese population is increasing but many
patients and some doctors are negative towards bariatric
surgery. There are only few data on bariatric surgery for
obesity among Koreans but so many studies indicate the
need for surgical treatment in severe obesity. Therefore,
we have to consider surgical treatment as an option for
severely obese patients.
