The eight to ten million people morbidly obese in this country,
those weighing 100 or more pounds over a healthy weight, may have
found a way to reduce the risk of health concerns associated with
obesity.
Gastric bypass surgery and other bariatric surgeries involve creating
a smaller stomach and rearranging the small intestine in people
suffering from obesity. Those who have had this type of surgery
claim to have experienced a dramatic improvement in their health.
However, statistical banter has played out between critics and
supporters of the surgery in regard to related benefits. Critics
argue that risks such as malnutrition and other medical problems
outweigh the benefits, while supporters claims the surgery saves
lives by eliminating the risk of common health problems relating
to excess weight.
One expert explains that bariatric surgery should be thought of
as a last resort after all other options have been exhausted.
In a combined analysis of 136 studies,
researchers found:
-
Patients lost an average of 61 percent of excess body weight
-
Patients lowered their cholesterol (70 percent) and blood pressure
(62 percent), as well as eliminated or eased diabetes (77 percent)
and obstructive sleep apnea (86 percent)
-
One in every 200 patients died a month after the operation
Overall, the study showed that those patients, who had gastric
bypass surgery or any other bariatric operation, experienced an
improvement in high cholesterol, high blood pressure, diabetes and
obstructive sleep apnea. Studies also showed that 70 to 80 percent
of cases were either eliminated or improved.
Apparently, resolution of diabetes occurred before weight loss
took place and days after the surgery. Researchers believe this
could be a result from hormone changes trigged by the surgery, some
of which are related to hunger.
