When dieting and exercising fail to help an obese person manage their weight, bariatric surgery may be suggested. One of the most popular types of bariatric surgery is a gastric sleeve surgery or sleeve gastrectomy. The main aim of this surgery is to reduce the amount of food that can be consumed in one sitting. It does not affect the amount of nutrients and fats absorbed from the food that has been eaten. A majority of the weight loss resulting from this surgery happens within 12-18 months.
A gastric sleeve surgery is a relatively safe, straightforward and short surgery. Prior to surgery, few patients would have been given a special diet. This surgery is always performed laparoscopically popularly known as keyhole route. More than half the outer side of the stomach is removed. The remaining part of the stomach takes the form of a tube.
Though recovery from any surgery varies from person to person, most patients are able to walk and allowed sips of water by evening. Though certain amount of pain and discomfort is expected, this remains in bearable range with pain killers. Usually liquid diet is advised for 2 weeks followed by soft foods for 4 weeks.
You will notice that you feel fuller much faster and are able to consume a very limited portion of your normal food intake. It is essential to drink plenty of water to remain adequately hydrated and to prevent constipation.
On an average, this surgery can help people lose up to 70% - 100%% of their excess body weight. However, this depends largely on your understanding and compliance of post operative dietary changes. A dietician can also help you make right food choices, decide meal portions and address the right number of meals needed by your body. For long term weight maintenance it is important not to fall back to your earlier lifestyle and to maintain a positive attitude.
