7 St George Obesity Surgery Unit | Bariatric Book | • Change in anatomy: Reducing the size of your stomach and bypassing a section of your intestines. Therefore, you feel full after eating a small meal. • Reducing the stomach hormones that make you feel hungry. Therefore, you feel fuller for longer. • Causes gut symptoms, when you eat high fat and high sugary foods. This works as a negative feedback so you avoid eating these foods. These restrictions in total food volume result in reduction in total energy intake, hence your body is forced to use its own fat stored energy and therefore weight loss occurs. Bariatric surgery is not a quick fix or a magic wand You should think of it as a tool to help you with your weight loss journey. For best results you will still need to make changes to your lifestyle and eating patterns. However, you can facilitate these changes. What is life like after bariatric surgery? Initially the surgery is very restrictive and you need to go through stages of fluid, puree and soft diet. You’ll only eat small volumes and therefore you need to prioritise what you eat to prevent any complications. Drinking adequate fluid, having protein at each meal and your multivitamins are the initial priorities. However, as your smaller stomach heals and recovers from surgery, you will be able to eat 3 very small meals and include all food groups in your diet. Long term, the key point is that a small meal will now satisfy you, hence the experience is different to dieting and therefore sustainable in the long term. However, you still need to make good food choices to ensure good nutrition. For prevention and treatment of nutrition deficiencies; you need to do blood tests to monitor key nutrition markers. Patients who do not make changes to their dietary and lifestyle habits and continue to eat inappropriately after surgery regain some or all of their weight. SURGERY WILL HELP YOU TO EAT LESS FOOD, AND STILL BE SATISFIED LESS FOOD = WEIGHT LOSS
