Bariatric surgery is not the easiest option, often the only one, for people with a high body mass index and comorbidities caused by it.
Gastric sleeve surgery (Vertical Sleeve Gastrectomy) involves the removal of the part of the stomach that produces a hunger hormone called ghrelin, helping increase the time between meals - the feeling of hunger is reduced.
The patient feels well-fed with smaller portions of food. When you eat, your small gastric sleeve fills up with every bite of food, signalling to your brain that you're well-fed. Since the stomach is smaller, your brain thinks that you have eaten a larger portion of food than you actually did.
Most patients are ready to return to daily activities, including work, within about 10 days. After 3-4 weeks, heavy physical activity can be resumed.
Sleeve gastrectomy is a surgical treatment for obesity and obesity-related medical conditions. It is only offered to people with serious health conditions associated with obesity or who are at high risk of developing them. Sleeve gastrectomy can improve and even prevent diseases:
The risk of gastric sleeve surgery is much lower than the risk of obesity and related diseases. The rate of possible complications is much lower than with other conventional surgeries, including gallbladder removal and hip replacement. Most gastric sleeve surgeries are performed using minimally invasive surgical techniques, which means less pain from the incisions and faster recovery.
The patient has severe obesity (class III). This is determined by BMI (body mass index), calculated based on weight and height, as well as related health conditions. Class III obesity means a BMI of 40 or higher or a BMI of at least 35 with at least one comorbidity.
Compared to other bariatric surgery methods, Gastric sleeve surgery is simpler, faster and safer. Because the operation does not change the shape of the bowel, there is very little chance of long-term nutritional complications.
The patient must undergo health checks before surgery (blood tests, electrocardiogram, abdominal ultrasound, chest X-ray, fibrogastroscopy, anaesthesiologist consultation).
The surgeon will prescribe to exclude carbohydrates from the menu three to four weeks before surgery, basing your diet on protein. The goal is to lose some fat in the abdomen and liver so the operation is safer.
You should not eat or drink anything for 12 hours before surgery. This is necessary for the stomach to be empty during the procedure. Food or liquid left in the stomach during surgery can cause unpleasant or even dangerous side effects.
The hospital stay after surgery is two to three days. The patient must strictly adhere to his menu, which is specifically designed after bariatric surgery.
The patient will have to undergo examinations after surgery – blood tests (1 month, 3 months, 6 months; 2 times a year). We monitor the progress of the patient's weight loss, associated health conditions and all possible side effects of surgery. In addition, it is important for the patients to take good care of themselves and follow the necessary postoperative lifestyle recommendations in order to maintain their health and lose weight.
Strict dietary guidelines will need to be followed in the short term. After a few months, the patient will be able to switch to normal healthy food, but still have to choose meals wisely. Since the patient will not be able to eat as much as before, he will need to make sure that what he eats is nutritious enough to provide enough energy. Vitamins will need to be taken if necessary.
