How Much Water Should You Drink While Taking GLP-1 Medication?
When you're working on weight loss—especially while taking a GLP-1 medication—staying hydrated isn't just a nice idea. It’s essential.
Many patients are surprised by how much their habits change once they start one of these medications. Appetite goes down. Portion sizes shrink. But that can also mean you're unintentionally drinking less water than your body needs.
Why Water Matters More on GLP-1s
GLP-1 medications can affect digestion, slow gastric emptying, and reduce hunger signals. As a result, some patients forget to drink enough fluids throughout the day. That can increase your chances of constipation, fatigue, and other common side effects.
Hydration supports digestion, regulates body temperature, cushions your joints, and helps your kidneys do their job. In other words, it’s not just about quenching thirst—it’s about helping your body function at its best while losing weight.
How Much Water Should You Aim For?
There's no one-size-fits-all number, but a general rule of thumb is around 64 to 80 ounces (about 8–10 cups) per day for most adults. That number may need to be higher if you're active, live in a hot climate (hello, Texas), or are losing a lot of water through sweat.
Instead of obsessing over exact ounces, try to sip steadily throughout the day. If your urine is light yellow and you’re not feeling thirsty, you’re probably in good shape.
Tips to Make It Easier
Carry a refillable water bottle. Add a splash of citrus or a few cucumber slices if you get bored of plain water. And don’t wait until you’re thirsty—by that point, you’re already a little behind.
If you’re experiencing common side effects like nausea or constipation while taking a GLP-1, boosting your fluid intake may help ease symptoms naturally.
