Gastric bypass surgery is one of the most popular weight loss surgeries in Australia. For this one, a series of steps is being initiated. The very first step towards this surgery is to identify any existing nutritional deficiency. Mineral and vitamin deficiency usually happen in obesity and should be addressed before undergoing the procedure.
The surgery has two goals. One is to reduce stomach volume and the other one is to shorten the transit time of food in the intestine. After having the surgery, the stomach would not be able to take in large meals. This is a way of limiting food intake.
In addition, food also bypasses a big part of the intestine and have very little time to interact with pancreatic and liver enzymes. This results in the drop of nutrition absorption from the diet. For the majority of gastric bypass surgeries that are done today, just 50cm of the intestine is being allowed to normally function.
With great reduction in the body’s capacity to assimilate food, the postoperative period could be a bit tricky. The patient is only allowed to consume fluids for the first two days after the surgery in order for the gut to recover. Then, the gut is retrained for almost two months before the patient could get back on eating a normal diet.
During recovery time, the limitations that are imposed by the procedure needs to be kept in mind. After the procedure, the stomach is smaller and could only hold about eight ounces at a time. Also, by this time, the stomach has lost its ability to initiate digestion.
The Role of Nutrient
The kind of nutrient that is chosen also deserves important consideration. The selected micronutrient need not affect the stomach’s emptying time while giving energy for recovery. Given this, fats and carbohydrates are at either end of the spectrum and are neither suitable. Fats slow down the gut and this usually ruled out due to its direct link to obesity. On the other hand, carbohydrates pass through quickly and produces uncomfortable symptoms such as sweating, diarrhea, bloating, and vomiting.
Aside from the mentioned advantages, a diet that is high in protein has an important role to play to treat obesity. The surgery limits excessive calorie intake in order to prevent weight gain. But the accumulated adipose tissue should be expended to achieve weight loss goals.
In addition, the basal metabolic rate needs to be increased to burn stored fats and lessen BMI. One way to achieve this is through a high-protein diet. This is because protein increases the basal metabolic rate through stimulation of protein synthesis.
The popularity of gastric bypass surgery is Australia and even in other countries is fast increasing and this is because of the benefits the surgery has to offer as far as weight loss is concerned.
