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.
In order for the weight loss journey to be a success, combination of regular exercise, nutrition and behavior modification are required. 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. By either enhancing or maintaining energy, weight loss is improved after bariatric surgery.
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. Bariatric surgery contributes to weight loss in two ways and they are restrictions or malabsorption. In the case restrictions, bariatric surgery limits the amount of food the stomach can hold thereby limiting the number of calorie intake.
As for malabsorption, bariatric surgery is used to shorten or bypass part of the small intestine which reduces the amount of calories and nutrients the body absorbs. Sleeve gastrectomy, gastric bypass, laparoscopic adjustable gastric banding and duodenal switch with biliopancreatic diversion are the types of weight loss surgery. The procedure that involves laparoscopic adjustable gastric banding requires the use of a band containing inflatable balloon that is placed on the stomach’s upper part.
The band creates a pouch on the stomach leaving a narrow opening on the stomach. Under the skin of the abdomen a port is placed in which a tube is connected to the band removing and injecting fluid. 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.
