Tirzepatide (sold as Mounjaro for Type 2 diabetes and Zepbound for weight loss) has garnered attention for its dual-action ability to lower blood sugar and support weight loss. However, as with any medication, it's essential to be informed about its potential side effects. Given its newness to the market, questions remain about how safe Tirzepatide is for long-term use, especially for those with underlying health conditions such as chronic kidney disease (CKD).

At Genesis Lifestyle Medicine, we prioritize your well-being by providing personalized care and detailed information on treatment options. Whether you’re considering Tirzepatide for diabetes management or weight loss, understanding the medication's impact on your kidneys and other key side effects is crucial.

How Tirzepatide works

Tirzepatide is a first-in-class medication that targets two essential hormones: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). These hormones regulate blood sugar and appetite by slowing food digestion, reducing hunger, and improving insulin sensitivity. As a result, it not only helps control blood sugar in Type 2 diabetes patients but also promotes weight loss, making it a potential treatment for obesity.

How Tirzepatide impacts your kidneys

Your kidneys are critical in filtering waste from the bloodstream and balancing fluid levels. Diabetes and obesity, two conditions often treated with Tirzepatide, are major risk factors for kidney disease. High blood sugar can damage the small blood vessels in your kidneys, while excess weight strains kidney function. Consequently, any medication prescribed for these conditions should be thoroughly examined for its impact on kidney health.

Clinical trials of Tirzepatide have shown that it may offer some kidney-related benefits for people with Type 2 diabetes. Some studies suggest that it can lower the risk of albuminuria, a condition in which the kidneys leak protein into the urine, an early sign of kidney damage. However, it’s important to note that these findings are preliminary, and more long-term data is needed to fully understand how the drug affects kidney health over time.

Key kidney-related risks and side effects

Although Tirzepatide may offer some protective benefits for kidney function, it's not without its risks. Here are some potential kidney-related side effects to watch for:

• Acute kidney injury (AKI): Tirzepatide, like other GLP-1 receptor agonists, has been linked to rare cases of acute kidney injury (AKI). AKI occurs when the kidneys suddenly lose their ability to filter waste, leading to a dangerous build-up of toxins in the blood. Symptoms of AKI include swelling in your legs and feet, fatigue, nausea, and confusion. If you experience these symptoms while taking Tirzepatide, contact your healthcare provider immediately.
• Dehydration and kidney strain: One of the most common side effects of Tirzepatide is gastrointestinal distress, including nausea, vomiting, and diarrhea. These symptoms can lead to dehydration if not managed properly. Dehydration, in turn, can strain the kidneys and may lead to kidney complications, especially if you have pre-existing kidney issues. To minimize this risk, it’s crucial to stay hydrated while taking the medication.
• Electrolyte imbalances: Tirzepatide can also cause electrolyte imbalances due to its effects on the gastrointestinal system. Vomiting and diarrhea can lead to a loss of vital electrolytes like sodium, potassium, and magnesium, which are critical for kidney function. Imbalances in these electrolytes can contribute to kidney dysfunction or exacerbate kidney conditions.

What to do if you experience side effects

If you begin taking Tirzepatide and notice any signs of kidney-related side effects—such as swelling, unexplained fatigue, or changes in urination—it's crucial to seek medical advice promptly. Early intervention can prevent minor issues from becoming serious complications. Additionally, regular monitoring of kidney function through blood tests and urine analysis can help ensure that your kidneys are functioning properly while taking Tirzepatide.
