Individuals that struggle with obesity can undergo a surgical procedure which is known as bariatric surgery. 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. An individual is able to lose weight and 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 fat metabolism and the energy balance is changed when the anatomy of the gastrointestinal tract is changed by using gastric sleeve, gastric bypass and laparoscopic adjustable gastric banding.
Bariatric surgery is a tool in the weight loss process and should be combined with regular exercise, nutrition, behavior modification among others. Reducing hunger and appetite while at the same time increasing the feeling of fullness is resulted by the affecting of intestinal hormone production through bariatric surgery. The desire to eat is reduced when the production of intestinal hormone is affected as a result hunger and appetite is reduced and feeling of fullness increased. There are differences in hormonal changes when it comes to bariatric surgery while comparing to dietary weight loss programs. Bariatric surgery actually improves weight loss changes by maintaining or enhancing energy.
Hormonal changes relating to dietary weight loss doesn’t result to maintenance or enhancing of energy as there is no balance created. Due to the presence of unbalanced energy, weight gain can be resulted by those per taking dietary weight loss. Individuals that have undergone bariatric surgery are able to engage in physical activity which reduces insulin hormone and cortisol hormone. 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. A band containing inflatable balloon that is placed around the upper part of the stomach then fixed in place is the procedure involved in laparoscopic adjustable gastric banding.
A stomach pouch is created while leaving a narrow opening on the stomach. A tube is connected to the band removing and injecting fluid from the port from which it has been placed under the skin. The size of the band is adjusted by the inflation or deflation of the balloon to which the fluid is injected or removed through the port.
