Gastric Bypass Advice
There are two type of bypass weight loss surgery. These are called Roux En Y gastric Bypass and Single Anastamosis (mini gastric bypass) surgery. There is a common element that both bypass surgeries contribute the possible short term dumping syndrome when fatty or sugary foods or fluids are consumed. Anatomically they are very different. Two diagrams are illustrated below.
Some key points to remember for long term management of the bypass:
- The bypass does not create a physical barrier to stop eating as in the initial few months post the gastric sleeve. Portion control is still up to the individual to manage.
- The Roux-en-Y bypass works similar to the band without adjustments. Meaning after the food exits the oesophagus, it stalls in a holding bay of 30ml capacity. Try and stop at a small toddler portion of food eaten over a 15min time frame.
- The mini gastric bypass (MGB), works similar to the sleeve gastrectory. Try and keep the portions per meal to 1/2 cup solid food, as this is what fits into the initial sleeve structure of the MGB.
- Initially protein drinks may be required to help meet protien intake more for a short term rather than long term. Everyone nutritoanl requirements need to be tailored and assessed to receive guidance for extra supplementation,
- A good quality multi vitamin specifically for weight loss surgery is crucial to avoid malnutrition.
