What eating will look like after bariatric surgery

After surgery eating will be entirely different!  Especially at first.  There are 4 stages to the post op diet.  You are on Stage 1 during your hospital stay and will be onto Stage 2 by the time you go home.

How long is your hospital stay?  I totally forgot to mention this during my explanation of the surgeries.  The gastric bypass surgery takes about 4-5 hours to complete and the sleeve about 1-2 hours, however with the bypass you are generally in the hospital just overnight and the sleeve approximately 2 days.

I also said to come back yesterday and I would tell you when my surgery was and I totally didn’t tell you the date of my surgery!  The doctor wasn’t booking out 6-9 weeks he was booking out 4 weeks.  My surgery is set for February 22!!!

Okay, back to the real topic of this blog – post op diet.

STAGE 1 – CLEAR LIQUIDS!

This stage usually lasts 1-2 days. Each meal is about ½ cup in size.

Here is a sample menu:

It doesn’t look like much but believe it or not you have a hard time eating all of it.

Between meals you need to sip zero calorie liquids to get in your 48-64 oz per day to stay hydrated.

STAGE 2 – LOW FAT FULL LIQUIDS

            This stage lasts 2 full weeks.  This allows your stomach to heal after surgery. Your stomach will be swollen and sore and it might be difficult to eat all that you need to make sure you meet fluid and protein requirements.

Goals for this stage are 60-80 grams of protein, 48 ounces of zero calorie fluid.  Each meal should be ¼ c to ½ c in size.  In order to make sure you meet your protein goal, you should eat your protein first!

This is a FULL liquid diet.  No chunks!  You need to use a strainer to make sure that all foods are smooth.  You cannot blend or puree solid foods during this stage either.  Cream soups still need to be strained to get out the lumps – example – cream of chicken you must strain to get out the chunks of chicken.

Honestly, baby food is a good substitute during this phase.  You can get your fruits and vegetables and they are already strained for you.

STAGE 3 – PUREED/SOFT-TEXTURE

            This stage lasts for another 2 weeks.  It starts about 2 weeks after surgery.

During this phase texture is key!  Food needs to come easily through the tines of a fork.  All meats need to be pureed.  Your goals for protein are still 60-80 grams and fluid is still 48 ounces.  Meal size has increase to ½ c to ¾ c in size.  They also suggest baby foods during this time, with adding baby pureed meats (eww).

STAGE 4 – REGULAR

            This starts about week 5 or 4 full weeks after surgery and it is how you will eat for the rest of your life.

Goals = AT LEAST – 60 grams of protein, 48-64 oz zero calorie fluid, 60-80 gram carb

            NO MORE THAN – 1000-1200 calories, 120-140 gram carbs, 25-30 gram fat

At the beginning you need to take things slow to find out what you can now tolerate.  Some people find that after surgery they can no longer tolerate dairy products.  Some find that a food they once loved now, just doesn’t agree with them.  It’s a brand new world after bariatric surgery in more ways than one.
