Gastric Sleeve Surgery
What is the gastric sleeve?
The gastric sleeve otherwise referred to as Laparoscopic sleeve gastrectomy, is the world’s most widespread weight loss procedure. Gastric sleeve surgery has expanded rapidly over the years and most recently accounts for the highest proportion of procedures in the NHS compared with the gastric band or gastric bypass surgery.
The concept of the gastric sleeve is as simple as it is effective. In this surgical operation, the abdomen is laparoscopically accessed. Small incisions (cuts) are made on the stomach along its length removing up to 80%, thereby producing a reduced stomach.
Post-surgery, the food you consume still enters and exits the stomach as usual (unlike the gastric bypass), although you will have a much smaller stomach.
There are two ways by which the gastric sleeve helps you to lose weight:
- It reduces the overall size of your stomach by up to 80%,thus, you will feel satisfied easily by consuming a small quantity of food.
- It alters the hormonal balance and level of protein in the stomach. The hormone ‘ghrelin’ which is responsible for increasing your appetite and otherwise referred to as the Hunger Hormone is removed, thereby resulting in suppression of appetite.
Due to these changes, sleeve patients lose weight rapidly following the surgical procedure.
It is important to remember that your weight loss is not directly related to the size of your remaining stomach. The alterations made to the gut hormones will help promote weight loss regardless of whether you have a proportionately tight or loose sleeve.
Post gastric sleeve surgery, we expect loss of excess weight between 60% and 70% for most individuals. This category of weight loss surgery has equally aided people with obese-related long-term health conditions such as Type 2 Diabetes and PCOS.
Am I eligible for the gastric sleeve?
In order for you to be qualified for a gastric sleeve, you must have a BMI of 35 or above.
How Long Is Gastric Sleeve Surgery
The surgery usually lasts for 60-90 minutes. In most cases, 4 or 5 small horizontal incisions will be made on the tummy via which the instruments are inserted. The incisions made will leave behind small scars which are usually not more than 5mm long.
After the surgery, you will stay in the hospital overnight. You will be discharged home and advised to rest for at least 7 days in order for your body to fully recover.
How much weight will I lose with the gastric sleeve?
The main reason for choosing a gastric sleeve for the majority of patients is to lose excess weight. The procedure is an effective one. Studies have shown that an average excess weight loss of 60%-70% over a period of 2 years is achieved amongst patients that undergo this surgery.
The most appealing aspect is that the weight loss usually occurs rapidly, as the procedure curbs and alters appetite.
In order for you to maintain the weight loss results for a longer term, you must make significant changes to your diet and routine exercises.
