A gastric sleeve surgery procedure is a ‘restrictive’ type of weight loss surgical method which works through making the stomach smaller and assists in losing weight due to restriction of diet intake.
The surgery can be performed using a conventional ‘open-type’ surgery or it can be performed through a minimally invasive surgical method using a laparoscope.
The surgical procedure requires administrating general anesthesia to the patient. The surgeon will ideally make an incision along the abdomen for a conventional method, or make a series of very small incisions to insert the laparoscope which is a thin and flexible surgical tube that has a video camera and light attached to one end while the other tubes have tiny surgical instruments attached to them that are required to perform the surgery.
The surgeon will remove more than half of the stomach and leave a thinner vertical sleeve about the size of a banana. Surgical staples are used to keep the new shape of the stomach. As a major portion of the stomach is removed this becomes an irreversible type of surgery.
This surgery is, at times, used in combination with a number of weight loss procedures and is done in various steps.
You might experience slight discomfort and pain in the abdomen and the doctor will prescribe painkillers for the first few weeks to relieve the abdominal pain. The incision also tends to be sore and tender for a few days.
After the surgery you might feel full even after eating lesser amount of food as compared to earlier. The food may be passed on to the small intestine for digestion more quickly as well. This is called the ‘dumping syndrome’ and may result in diarrhea and make you feel nauseated, dizzy and faint. It may also make it difficult for the body to absorb nutrition from the food.
The doctor will advise you regarding the type of diet as well as the amount of food per meal that you should have ideally in order to promote weight loss in a significant manner. For the first month the doctor will usually suggest you a diet consisting of soft food and liquids to allow your stomach to get accustomed to normal diet contents. There might be certain irregularities with your bowel movements after the surgery. It is important to eat smaller morsels and chew the morsels thoroughly in order to facilitate better digestion.
