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.
Many obese related conditions such as high blood pressure, heart disease, type 2 diabetes 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. 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. Following bariatric surgery, weight loss is improved by either enhancing or maintaining 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. Insulin hormone and cortisol hormone are reduced through engaging of physical activity by individuals that have undergone through bariatric surgery thereby resulting to production of other factors that reduce the uptake and storage of fat into fat storage deposits. In addition bariatric surgery is known to contribute to weight loss in two ways either malabsorption or restrictions. As a way in which weight loss is achieved is through restrictions which means limiting 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. Four types of weight loss surgery includes; sleeve gastrectomy, gastric bypass, laparoscopic adjustable gastric banding 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.
The band creates a pouch on the stomach 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 fluid that is injected or removed through the port, inflates or deflates the balloon while adjusting the size of the band.
