Pre-Op Diet

Starting 2 weeks before your surgery you must go on a pre-op diet.  DHMC puts everyone who is having abdominal surgery on this diet.  It is not specific to just gastric bypass or sleeve surgery.  The main reason for this diet is to reduce the size of your liver.  The diet helps to flush out the fat out of your liver and shrinks it down in size and makes it more malleable.  During surgery they need to move your liver out of the way, and before they would “cut you open” to move your liver because it would be hard and not pliable.  If they went to move it would crack and bleed.  With this diet it becomes very pliable and can fold and bend easily and will not crack and bleed.  This way they can do the surgery very easily via laparoscope.

I remember when my mom had hiatal hernia surgery a few years ago she also was on this diet.  

This diet follows these daily goals:

            800-1000 calories

            60-100 grams of protein.  If your BMI is >50 protein goal is 80-100 grams

            80-100 grams of carbohydrates

            48-64 ounces of calorie free, caffeine free fluids per day.

In the workbook that DHMC gives you they give you 4 daily options of to follow.  They are ‘guidelines’ to help you make choices to fit your meal plan.  They include 3 meals a day and snacks. They also warned us that we would be hungry during this time, as most of us aren’t used to eating just 800-1000 calories, but if we chose our calories wisely and remember to drink our water we will do much better.

Drinking water, or calorie free fluids is very important.  I prefer water myself.  After surgery we need to stay hydrated and we need to sip water all day long but there are rules we need to follow:  No drinking 30 minutes before a meal, during a meal, or 30 minutes after a meal.  The reason for this is your stomach pouch will be extremely small.  Drinking before your meal will fill our pouch with fluid and there won’t be room for your food and you need to get your food (nutrients) in too.  Drinking during a meal and after a meal will flush the food too quickly from your pouch into your small intestine.  This will be extremely uncomfortable and not healthy!

During this time we are to practice chewing!  Most people do not chew their foods as well as they should.  We need to chew them until they are almost liquid before swallow them after surgery and learning now and getting into that practice is a good thing.  Eat slowly!  Protein first!  It is important to get the protein in first.  Protein, then veggies, and then starch.

I start my diet on February 8, 2017.  One week from today.  I should also see a weight loss during this time.

It’s getting real folks! Stay tuned as I explain more about the process and how I am doing!
