Bariatric surgery is a surgical intervention that helps people struggling with obesity. Bariatric surgery is an effective treatment for obese individuals as compared to other weight loss therapies such as increasing exercise, commercial weight loss programs and consuming fewer calories. Not only does bariatric surgery help an individual to lose weight but also improve their health quality.
Conditions such as high blood pressure, heart disease, type 2 diabetes are obese related and are resolved by bariatric surgery. The anatomy of the gastrointestinal tract is changed by using gastric sleeve, gastric bypass and laparoscopic adjustable gastric banding that goes hand in hand with bariatric surgery so as to change the fat metabolism and energy balance.
Bariatric surgery is a tool in the weight loss process and should be combined with regular exercise, nutrition, behavior modification among others. The bariatric surgery affects the production of intestinal hormones in a way that reduces hunger and appetite while increasing the feeling of fullness. When hunger and appetite is reduced and feeling of fullness increased the desire to eat is generally reduced and thus weight is maintained. Bariatric surgery and weight loss programs results to differences in hormonal changes but at different ranges. Following bariatric surgery, weight loss is improved by either enhancing or maintaining energy.
Maintenance or enhancing of energy isn’t expected from those undertaking dietary weight loss as there is no balance. Due to the presence of unbalanced energy, weight gain can be resulted by those per taking dietary weight loss. Bariatric surgery results to massive weight loss as individuals engage in lots of physical activity which reduces insulin hormone and cortisol hormone resulting to production of a number of other factors that reduce the uptake and storage of fat into fat storage deposits. Malabsorption or restrictions are the two ways in which weight loss is contributed through bariatric surgery. In the case restrictions, bariatric surgery limits the amount of food the stomach can hold thereby limiting the number of calorie intake.
The amount of calories and nutrients the body absorbs is reduced through bariatric surgery in the case of malabsorption. The types of weight loss are; laparoscopic adjustable gastric banding, sleeve gastrectomy, gastric bypass and duodenal switch with biliopancreatic diversion. Laparoscopic adjustable gastric banding involves the use of a band containing inflatable balloon that is placed around the upper part of the stomach then fixed in place.
A stomach pouch is created while leaving a narrow opening on the stomach. A port is placed under the skin of the abdomen in which a tube is connected to the band removing and injecting fluid. The balloon that is attached to the band is either inflated or deflated by the fluid that is injected or removed through the port.
