WEEKS BEFORE
To determine the suitability & your body’s fitness for the surgery we will take you through medical, psychological, nutritional assessments and pre-counselling.
The pre-surgery weight loss diet is essential because it is low in fat and carbohydrate content, helping reduce your glycogen levels and reduce your liver size so that the operation can be conducted.
There should be no intake of caffeinated drinks (coffee and energy drinks) at least a week before your surgery date. Your dietary intake in the week leading up to the surgery should be light, like vegetables and fruits.
DAYS BEFORE
You'll need to stop smoking, eating heavy unhealthy meals, stop taking aspirin, ibuprofen, and other blood-thinning medicines in the days before your surgery. You shouldn't eat or drink anything after midnight before surgery.

Post Procedure
Recovery may vary from person to person, but here’s what you need to know:
Hospital Stay: 2-3 days after the surgery to ensure proper healing, rehabilitation, and monitoring of progress. Patients who have undergone laparoscopic procedures may return to work within 1 week after surgery. However, it is not advisable to engage in intense physical work.
Shortly after surgery, you'll begin reintroducing foods into your diet in phases in consult with your nutritionist who will teach you how and what to eat with your reduced stomach size. You'll start consuming a clear liquid diet within 24 hours of your surgery, then advance to a full liquid diet, a soft food diet, and your regular diet in the weeks ahead. You will also have to reduce certain foods, such as simple sugars, including honey, white sugar, or syrups, to avoid dumping syndrome. You will need to chew slowly and fully, and not to drink 30 minutes before or after you eat. While it may seem demanding, ignoring dietary recommendations may cause constipation, dehydration, diarrhea, or in extreme very rare cases, gastric acid leakage.
You will have follow-up visits with your bariatric surgery team to help you develop good eating and exercise habits that will change your lifestyle. Your initial weight-loss may occur quickly, so it's important to get all of the nutrition and vitamins you need as you recover. To prevent nutritional problems after surgery, your doctor may advise on supplements like Vitamin B12 and iron.

How Is It Done & How Does It Work
Done laparoscopically under anesthesia in about 2-3 hours. The stomach is reduced by removing a portion of it. Then the middle part of the small bowel is excluded from food transit by connecting the last part of the small bowel (ileum) to the 1st part of the small bowel (duodenum). In summary, the food travels from the small new stomach to the distal intestine bypassing a long segment of the small bowel, which remains in the abdominal cavity, but is excluded from the food circulation. This reduces the food intake as well as absorption causing significant weight loss. Usually for BMIs over 40, with up to 70% excess weight reduction. Involves 3 components:
- Sleeve gastrectomy (restrictive component)
- Shortening the intestines food path (malabsorption component)
Laparoscopic surgery done using tiny incisions in the abdomen, under anesthesia and usually lasts about 3 hours with about 2 days as hospital stay. Weight loss occurs gradually being fastest in the first months. 1.5-2 years may be required for maximum weight loss.
