Surgery for Weight Loss
Severe obesity is a chronic condition that is difficult to treat through diet and
exercise alone. Weight Loss Surgery (Bariatric / Obesity Surgery) is a good option for people who are
severely obese and cannot lose weight by traditional means or who suffer from serious obesity-related
health problems. The surgery promotes weight loss by restricting food intake and, in some operations,
interrupting the digestive process. As in other treatments for obesity, the best results are achieved
with healthy eating behaviours and regular physical activity.
People who may consider gastrointestinal surgery include those with a body mass index
(BMI) above 35 — about 100 pounds overweight for men and 80 pounds for women (see our BMI chart). People
with a BMI between 32 and 35 who suffer from type 2 diabetes or life-threatening cardiopulmonary
problems, such as severe sleep apnoea or obesity-related heart disease, may also be candidates for
Obesity surgery to reduce obesity can now be performed laparoscopically, using
“keyhole” surgical techniques. The bariatric surgeon uses fibre optic lenses and small instruments
connected to a video camera, a procedure which entails smaller incisions, reduced pain, less scarring,
and a faster post-op recovery time. In 2000, a gastric band called the MIDband ® was used in France.
This was manufactured specifically for laparoscopic insertion. Other bands have followed.
Laparoscope-assisted surgery typically reduces the risk of incisional hernias (caused when abdominal
contents bulge through the weakness in the abdominal wall created by the scar). It may also result in
more internal complications, such as anastomotic leakages from connections between sections of intestine
and between the stomach and intestine. At Asian Bariatrics, the complication rates are lesser than the
international published data because of exclusive approach, high level of expertise and focused high end
technology used for surgery. Bariatric experts expect these complication rates to reduce as surgeons
become more experienced at laparoscopy.
Obesity surgery is a scientifically proven, more successful approach to weight loss
compared to a pill. Examples of obesity surgery include gastroplasty surgery, gastric bypass surgery,
and jejunoileal bypass surgery. Surgeries can cause huge amounts of weight loss to those who receive it
by reducing the amount of ghrelin (the hormone that causes hunger) produced due to a smaller stomach. A
smaller stomach demands a complete change in dietary decisions; as many who undergo obesity Surgery
typically cannot eat bread or overly sweet foods. One also drastically reduces his or her daily intake
of calories. Mortality rates of obesity surgery are relatively low, but specific aspects of the patient
such as weight, age, BMI, and heart health may increase/decrease mortality rates.
A Gastric band is a commonly used device in obesity treatment.
Type of Surgery
Overweight and obesity are raising medical problems of pandemic proportions. There are
many detrimental health effects of obesity: Individuals with a BMI (Body Mass Index) exceeding a healthy
range has a much greater risk of medical issues. These include heart disease, diabetes, many types of
cancer, asthma, obstructive sleep apnea, and chronic musculoskeletal problems. There is also an effect
of obesity on mortality.
People may find it difficult to lose weight on their own. It is common for dieters to
have tried fad diets only to find that they gain weight, or return to their original weight, after
ceasing the diet.
