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 18 months.
A gastric sleeve surgery is a relatively straightforward and short surgery. This surgery is performed laparoscopically or through a keyhole route. Major part of the stomach is removed & the remaining part of the stomach takes the form of a tube.
Though recovery from a gastric sleeve surgery varies from person to person, most are encouraged to consume water on the day of surgery and to walk by evening. Patients are put on a liquid diet for 2 weeks and soft foods introduced in week 3 which includes rice, pulses, eggs, fish and well cooked vegetables. 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 allow for smooth bowel movements and to prevent constipation.
On an average, this surgery can help people lose up to 80% of their excess body weight. However, this depends largely on consuming adequate proteins either through shakes or consuming fish, eggs and vegetarian protein sources like milk products, pulses etc. Weight loss plateau may happen during this phase and you can overcome them through change in your diet or exercise schedule. A comprehensive bariatric program can also help you address the right number of meals, type of meals and long term weight maintenance support. It is important to avoid falling back on earlier unhealthy lifestyle and to maintain a positive attitude.
