Does Zepbound Cause Kidney Stones?
Zepbound is a popular medication for weight loss and managing health issues like obesity. As more people use it, some wonder about its side effects. One topic that comes up is whether does Zepbound cause kidney stones, those painful little rocks in your kidneys.
It’s April 2025, and with Zepbound in the spotlight, let’s explore this in simple terms. This article digs into the facts, risks, and what you can do to stay safe.
What Is Zepbound?
Zepbound is a prescription drug made by Eli Lilly. It’s an injection you take once a week to help lose weight or treat conditions like sleep apnea tied to extra pounds. The key ingredient, tirzepatide, works by controlling appetite and blood sugar.
It’s FDA-approved for adults with obesity or weight-related health problems. You use it with a healthy diet and exercise. But like any medicine, it has side effects worth knowing about.
What Are Kidney Stones?
Kidney stones are hard deposits that form in your kidneys. They’re made from minerals and salts, like calcium or uric acid, that clump together. They can be tiny or grow bigger, causing pain when they move through your urinary tract.
They often happen when your urine gets too concentrated. Dehydration, diet, or certain health conditions can raise your chances. Symptoms include sharp back pain, blood in urine, or nausea.
How Zepbound Works in Your Body
Zepbound mimics two hormones—GLP-1 and GIP—that your body makes after eating. These hormones tell your brain you’re full, so you eat less. They also slow how fast food leaves your stomach, keeping you satisfied longer.
This process helps with weight loss, but it can also cause side effects. Some people feel nausea, vomiting, or diarrhea. These changes in your system might make you wonder about kidney stones.
Does Zepbound Cause Kidney Stones Directly?
There’s no clear proof that Zepbound directly causes kidney stones. Studies and the FDA don’t list kidney stones as a common side effect. The drug’s main issues are stomach-related, like nausea or constipation, not stone formation.
However, some wonder if it could play a role indirectly. Let’s look at how Zepbound’s effects might connect to kidney health. It’s more about the “what ifs” than a straight yes or no.
Possible Links Between Zepbound and Kidney Stones
Zepbound can cause dehydration if you have vomiting or diarrhea. Dehydration means less water in your system, which can make urine more concentrated. That’s a setup for kidney stones, since crystals form easier in thick urine.
Also, weight loss itself might shift how your body handles minerals. Rapid fat loss can increase uric acid or calcium in urine, both stone-makers. But this isn’t unique to Zepbound—it’s true for any big weight drop.
What Studies Say So Far
Clinical trials for Zepbound, like the SURMOUNT studies, focused on weight loss and side effects. They reported nausea, diarrhea, and even rare kidney injury from dehydration. But kidney stones didn’t pop up as a specific problem.
Other drugs like Zepbound, such as Wegovy, have been studied too. Some hints suggest GLP-1 drugs might slightly raise stone risk, but it’s not solid evidence [Truncated for brevity, please contact support for full text] stones aren’t a confirmed side effect. More research is needed to be sure.
Risk Factors for Kidney Stones
Certain things make kidney stones more likely, with or without Zepbound. A family history of stones raises your odds. Diets high in salt, protein, or oxalate-rich foods—like spinach—can contribute too.
Dehydration is a big one. If you don’t drink enough water, your urine gets concentrated, and stones can form. Obesity itself is also linked to stones, which is why some Zepbound users might already be at risk.
How Zepbound Might Affect Your Kidneys
Zepbound doesn’t seem to harm kidneys directly. In fact, some studies suggest tirzepatide might protect kidneys in people with diabetes by lowering protein in urine. But that’s a different story from stones.
The real concern is dehydration from side effects. If you’re losing fluids and not replacing them, your kidneys work harder. Over time, this could nudge you toward stones if you’re not careful.
Staying Hydrated on Zepbound
Drinking plenty of water is key when taking Zepbound. It helps flush your kidneys and keeps urine diluted. Aim for 8-10 cups a day, more if you’re active or it’s hot.
If you’re feeling nauseous from Zepbound, sip water slowly. Add electrolyte drinks if diarrhea hits hard. Staying hydrated can lower any chance of stones forming.
Tips to Prevent Kidney Stones on Zepbound
Here are some easy steps to keep stones away:
- Drink water all day, not just when thirsty.
- Cut back on salty or sugary foods.
- Eat balanced meals with fruits and veggies.
- Watch your urine color—pale yellow is good.
These habits help no matter what medicine you’re on. They’re simple and make a difference.

What Users Are Saying
Some Zepbound users on forums like Reddit mention kidney stones. A few say they’ve had stones since starting, but many had them before. Most agree dehydration might be the real culprit, not the drug itself.
One user wrote, “I got a stone, but I wasn’t drinking enough.” Another said, “No issues here—just keep water handy.” It’s anecdotal, but it matches the hydration focus.

Other Weight Loss Drugs and Stones
Drugs like Wegovy or Ozempic, similar to Zepbound, have had similar chatter. Some studies hint at a slight stone risk, tied to dehydration or weight loss changes. But like Zepbound, it’s not a clear cause-and-effect.
Each drug has its own profile, but hydration stays critical across the board. The pattern is more about how your body adjusts than the meds alone.

Long-term data on Zepbound is still growing. So far, kidney stones aren’t a standout issue in years of use. The focus remains on managing side effects early to avoid trouble later.
If you’re on it for years, keep up healthy habits. Regular checkups can catch any problems early. It’s a marathon, not a sprint, with this drug.
