Hydration After Bariatric Surgery: Why It Matters & How I Make It Happen
If you’ve had bariatric surgery—or are considering it—one of the things you’ll hear over and over again is “stay hydrated.” And that’s for good reason. After surgery, your body changes dramatically, and so do your habits. Staying on top of your fluids becomes more than just good advice… it becomes non-negotiable.
Why Hydration Matters Post-Surgery
Why Post-Surgery Matters Post-Surgery
Here’s the thing: after bariatric surgery, your stomach is smaller and your eating patterns shift, which can make it harder to get in enough fluids. But your body still needs hydration to:
- Regulate temperature
- Transport nutrients
- Flush out toxins
- Prevent constipation (trust me, it matters)
- Support your energy levels
- Avoid dehydration-related issues like headaches, dizziness, or even kidney stones
Even mild dehydration can throw your body off balance—especially when your intake is already limited.
My Honest Take: What Actually Works for Me
I’ve heard all the “rules.” Sip slowly. Avoid straws. Don’t drink 30 minutes before or after meals. And here’s the truth: some of those work for me, and some don’t. Let me break it down.
I Don’t Believe in the 30-Minute Rule Before Eating.
That whole “don’t drink 30 minutes before eating” rule? I’ve never followed it. I just don’t see the need. Drinking water before food helps keep me full, and it’s never caused me issues. Doctor
I ABSOLUTELY Follow the 30-Minute Rule After Eating
Now THIS one is non-negotiable for me. Drinking too soon after eating washes the food out of your stomach faster—and makes you hungry again sooner. No thanks! I always wait at least 30 minutes after meals to start sipping again.
I Use Flavor Packets—and I’m Not Ashamed of It
I get it. People love to freak out over chemicals. But let’s be real: a flavored water packet is still water. It’s a thousand times better than a sugary soda or a fast food milkshake. My goal is hydration. I love these Liquid IV flavors helps me reach it? Get yours here!

I keep a stash of these drink mixes and rotate flavors so I don’t get bored. Is it “clean eating”? Maybe not. Is it effective? Absolutely.
I Play a Game with Myself: 16oz Before Food
This one has been a total game-changer for me. I push myself to drink two of these Brumate era 40oz tumblers a day! I make a deal with myself: no food goes in my mouth until I’ve had at least 16oz of water. I also fill up with ice. Cold water is so refreshing. It helps me stay ahead of dehydration and keeps my hunger in check.
Yes, I Use a Straw
Let go of your pearls now!!! I know the “no straws” rule is drilled into us, but I’ve never had a problem. In fact, using a straw helps me drink more consistently and get my fluid in faster. These staw covers for my Brumate really help make it fun. I’ve learned to listen to my body, and if something works for me—I stick with it.
Final Thoughts
Hydration after bariatric surgery isn’t always easy, but it is essential. The trick is to find what works for YOU. Don’t be afraid to bend the “rules” a little—as long as you’re staying safe and taking care of your body.
Whether it’s flavor packets, straws, hydration goals, or water-before-food games—hydration doesn’t have to be a struggle. It can even be… fun? Okay, maybe that’s pushing it. But it is possible.
