How to Monitor Fluid Intake After Weight Loss Surgery

Would love your thoughts, please comment at the end of the post!


Hi everyone! So, I have been getting questions about fluid intake after surgery. Some talk about how difficult it is and some other issues with nausea and headaches, and all that can be attributed to not reaching your fluid goals and not getting enough of what your body needs in the hydration department.

Fluid Intake After Bariatric Surgery

How to Keep Track of Fluid Intake

So, I wanted to show you my favorite cup for keeping track of fluids at home. Hopefully, you can find something similar to this in your neck of the woods. So this is a cup I got while delivering my son, a few years ago in Oregon.

I like it because it has the measurements right here on the side. This one is particular has ounces and CCs. You might find one that has millimeters. It doesn’t matter whatever way you want to keep track of the fluids, but it is just the fact that having these actual numbers to keep track and write things down.

Hydration Goals Post Weight Loss Surgery

For most of you, we have a fluid goal of at least 64 ounces. So, that would be just three of these for the whole day. What I tell a lot of people to do is once you wake up in the morning, make a goal to get at least 20 ounces of fluid in from the time you wake up until about 3-4 hours later. So, if you are waking up at 7 AM, try to get 20 ounces in by 11 AM.

So what you can do is fill this whole thing with water and then just keep track. You know, at 9 AM, take a look and see how you are doing. Do you have 14 ounces left to go, do you have 18 ounces left to go or are you halfway through it?

And if you are at a higher end and you have a lot of drinking to do, literally sit down for a minute or two and sip one teaspoon at a time or less. You know, every 20-30 seconds take a small sip. To be a little more mindful and to make sure you get your fluid.

I always tell people that you know you’re going to eat and drink more and think about it more than you ever did before surgery, initially after surgery. Your pouch is so small, and you have to take the time to get the food and the fluid in that you need because the stomach is tiny.

It is prime real estate! So you can sit down and focus on this.

Drinking Fluids After Weight Loss Surgery

The other thing you can do is if you are going to have a protein drink or an 8-ounce cup of tea or decaf coffee… you are not going to put that in your water jug.

You can drink it on the side and when you have finished drinking, dump out as much fluid that was there in your protein drink or tea or decaf coffee that is in here because all those fluids add up to your total fluid requirement.

So, if you have 20 ounces in here of water but the first thing you do is drink an 8-ounce cup of tea, dump out enough water to the 12 because that is 8 ounces of fluid that you got. Then, you will have 12 ounces of liquid to drink before 11 AM or whatever it is.

Any Questions?

Just some tips! Let me know if you have any questions. It doesn’t have to be a cup like this from the hospital. You can use a CamelBak. That is another excellent option. Any glass, mug, jug or thermos that has these measurements on the side is a great tool.
