Did you know that, based on the data released by the CDC National Center for Health Statistics, 42.4% of Americans are obese? Unfortunately, this condition is associated with several health risks, such as end-stage renal disease, coronary heart disease, stroke, some cancers, and type 2 diabetes. Why do people become obese anyway? According to the US National Institutes of Health, intrinsic (i.e. genetics and health condition) and extrinsic (i.e. environment, food, physical activity, medications, stress, poor sleep, emotions) factors may lead to obesity. Eventually, posing risks to one's health. In most cases, obesity can be reverted through intense diet planning and lifestyle modification such as controlling food portions, renewing dietary habits, and engaging in more physical activities. However, when more serious health risks arise that cannot be managed by diet and exercise alone, you can opt for gastric bypass surgery which will help you lose weight faster. This surgery will make your stomach smaller, making you full faster with less food intake. Gastric bypass surgery involves modifying your stomach and small intestine. This means that you will not be able to absorb everything you ingest, which is why it is important for you to follow a pre-op and post-op diet. The pre-operative diet will prepare the patient for the surgery and will develop habits that he/she will need to survive the adjustment period after the surgery. Whereas, the post-operative diet is meant to help the patient recover and reintroduce food. If you have plans on doing this surgery, you have come to the right place!
