I am not a doctor, but... (post-op diet progression)

  • Popular Post
Over the last few weeks, I've seen a number of posts about "cheating" on the diet plan in the days and weeks immediately following surgery, and I am very concerned about this trend.


I am not a doctor, I do not play one on TV, and I am not dispensing medical advice.


However.


I am a registered nurse, and what I'm about to say is an informed and educated opinion.


Surgeons tend to give VERY detailed instructions about what to eat after a stomach surgery, and for VERY good reason.


Even when the surgery is arthroscopic and looks to be a very tiny surgery on the outside, it's a VERY BIG surgery on the inside. The VSG surgery leaves a staple/suture line the entire length of the stomach. That incision has to heal, and if you could see it, it would look like raw beef. If the incision were on the outside, we would be very careful with it, keeping it clean and bandaged while it healed. Of course, it's on the inside, so we can't do that. But we need to keep in mind that it needs to heal in the same way.


We have to eat, and that food will be against that raw incision. At the same time that we have to protect the healing stomach, we also have to get in plenty of fluids and nutrients, specifically Protein, in order to support healing. Protein is the primary building block for tissue, so it's critical to healing. Carbs are mainly just energy sources, so they're not as important, especially given that people having bariatric surgery have plenty of energy in their fat stores. This is why protein is stressed so heavily over carbs in the diets.


Additionally, the stomach is now in a new shape, and it basically has to learn how to function as a slender tube instead of a big bag. There's a learning curve. Kinda like a newborn baby's stomach. We don't dump steak and salad into a newborn's stomach for good reason - it doesn't know how to deal with it. Similarly, we don't want to do that to our new sleeve. We start off with stuff that's easy on the suture line and easy to digest, and as the suture line heals and the sleeve learns its job, start working our way up to "real" food.


So over the years, doctors have learned what foods are best for a healing stomach, and that translates into the post-op diet progression instructions.


Typically, that looks like this: Clear liquids, then full liquids, then pureed foods, then soft foods, then slowly move into a "full" diet beginning with high moisture content foods first. When moving from one stage to the next, it's typically advised to add just one food at a time, in small amounts, and see how it's tolerated. A food that's not tolerated well can be tried later on as well. If an entire stage is not being tolerated, back up to the previous stage for a while, and then try again more slowly.


Surgeons tend to specify how long to stay in each of these stages, what types of food make up each stage, and how to transition to the next stage. Every surgeon's instructions are a little different, and it's based on their experience and sometimes changes based on the patient's specific medical case.


The general idea in the very early weeks is to eat foods that will not stress the healing suture line, and do not have particles that are known to cut into the raw tissue or get embedded into the suture line. If a cut or embedded food particle gets infected, it can become an abscess and develop into a leak. A leak can be life threatening, and at the very least cause the patient to have to be hospitalized and possibly have more surgery to correct it. Foods that are particularly known to cause issues are those that swell up like rice, have seeds like strawberries, or have rough hard edges or hard to digest fibers like wheat crackers or raw vegetables.


There are people who eat all sorts of things against their doctor's orders and have suffered no ill effects, but this should not be used as an argument that the doctor's orders are not important. Similarly, you will find some people who smoke a pack of cigarettes every day and drink a pint of whiskey every day but live to 100. They are not representative of most people, and should not be used as the example other people follow.


The reality is that some people will develop abscesses and leaks because they ate things before they were cleared to by their doctors, and there is no way to predict who will have the complications and who will not. And the consequences can be as severe as death. It's not common, but that's how bad it can get. That's why the doctors give the instructions they do. They're not just testing you or trying to make your life hard. They are giving you the best information they have to keep you safe.


Violating these orders is not "cheating" on a diet. It's risking your life. I am not being overly dramatic with this statement, it is a fact that it has happened. You are risking your safety and your health if you violate these orders. It's not about "being human", it's not about "food addiction". It's about your safety and your health. It's hard to be on liquids only for 2 weeks (or more). Some people have huge cravings, or "head hunger" as we tend to call it here. Or just want desperately to chew something. No one is saying it's easy. But it's necessary. Distract yourself. Eat/drink anything that's allowed on your plan - freeze it, heat it up, try something that's opposite of what you've been having to shake it up. Walk around the house or the block. Suck on an ice cube. Count to ten or a hundred. Post about how hard it is, and ask people to help you get through it. But muscle through. It's nothing less than your health and safety.


As for why one surgeon will have his patients on clear liquids for 2 weeks while another only does 2 days? Or why one will skip a phase entirely? Each surgeon has different experiences that inform his practices. One is not right and the other wrong. They are each operating out of what they were taught and what they have seen in their own patient groups. They may have even modified the plan because of a specific health concern in your specific case. As a patient, you need to fully understand what your surgeon expects, and if you have a problem with the protocols get it straight with your surgeon and team BEFORE you go under the knife.


If you don't trust your surgeon and his protocols, find another surgeon. I personally would question a surgeon who doesn't allow any Protein drinks including the clear ones for 2 full weeks post op (saw that in one patient's instructions on this site) and likely wouldn't work with that surgeon, given what I know about the needs of protein for healing. But after surgery is not the time to be questioning the surgeon's protocols. Get those questions asked and answered to your satisfaction well before the surgery date.


If you are having surgery, and you have not been given your post-op instructions, at the very least for the first 2 weeks post-op, do not proceed with the surgery until you have that information. We have people posting here stating that they were sent home without clear instructions as to what they were supposed to eat or drink, just a vague statement about "full liquids". That is not sufficient information, and instructions should be given WELL BEFORE the surgery, not after. You should fully understand what will be expected in the weeks after the surgery before consenting to the surgery, or your team is not doing their job.


(This ends my sorta rant about post-op diets and "cheating")


Good luck to everyone!

you should share that recipe, I'm one of those crazy folks who loved prunes and prime juice.

Sent from my iPhone using the BariatricPal App

1 cup unsweetened applesauce

1 cup unprocessed wheat bran

1/2 cup prune juice

mix well, store in refrigerator

each morning, take 1-2 Tbsp with 8 oz or more of Water.

My PCP says most of her patients, even those with IBS-C, manage to stay regular with this and don't need stool softeners or laxatives if they'll use this regularly and drink lots of water.

I told her I couldn't stomach the prune juice, we talked about alternatives and I'm going to try to make some up with some fig preserves once I make it to the farmer's market again, I'll report on if that worked or not. :)

I'm glad you posted this but it is an absolute waste.

It is like walking into a heroine den and talking to people about being clean. The people that are food addicts are lost causes, nothing is going to stop them from self harm.

Wow. No cure for addiction does not mean no life absent our triggers. I know so many wonderful people living in recovery, including my mother with 21 years sobriety.

I am expecting to struggle with certain trigger foods (chocolate and baked goods for me) all my life. Avoiding them works best for me now, and very likely after the sleeve too.

The vast majority of us food addicts have successfully abstained many times. And eventually returned to these foods and/or beverages.

I love the original post on

N this thread. Thank you for the compassionate and clear reminder.

pear juice is what pediatricians use when kids won't drink prune juice. Try that

I've been hesitant about posting some things here simply because my surgeon's practice is a lot less conservative than most of the plans I've read about.

But eventually, I've been okay posting as long as I say "my surgeon wants me to do XX". People should be listening to their own surgeons and not fishing for permission to behave badly here.

If you're not going to listen to your surgeon, why are you even considering surgery? Obviously doing what YOU think is best has gotten you morbidly obese and sick. YOU are not a good source of behavior. Listen to your surgeon instead.

Absolutely. My surgeon is pretty liberal with her diet progression compared to many I've seen here as well. But each surgeon has developed their protocol based on their training and experience. After surgery when you're experiencing cravings and head hunger is not the time to compare my plan with yours and decide your surgeon is being too conservative because you're wanting to move more quickly. Follow your doctor's instructions. Period.

Great post! I wish I could believe that everyone would take it to heart, but I know better.

I'm talking about real food addicts. There are people that post here eat fried chicken with mashed potatoes and gravy their first week home. There is no hope for those people. If they are willing to ignore the pain and potential death of eating real food that early post-op, they are beyond helping.

I'm not talking about the person that has a hard time walking past the donuts in the office break room.

Read here long enough and you will see some truly amazing things.

Extraordinarily WELL DONE!! Complete and understandable information from a VERY credible perspective

Really great info! Since starting soft/solid food, I think I spit out more than I actually eat. After a few chews I think it's too dry and I just can't swallow. I can't fathom eating any kind of bread right now.

  • 2 weeks later...

@@theantichick thank your for you well thought out post. It helps me to understand why I am doing something. Also, I've been wondering for days what's been going on inside my body and honestly there isn't much info about that. Most information just focuses on the surgery itself and not how the healing process progresses internally. If you or anyone else out there knows where I can find this info please share. Thanks again for taking the time to write out all that info out. It will help many people, maybe not all.
