Mounjaro and Kidney Health – What Tests Reveal
Mounjaro is one of the newest medications for type 2 diabetes and weight management. Many patients are interested in its benefits, but safety questions remain. A common concern is whether Mounjaro affects kidney health.
At Marylebone Diagnostic Centre, 73 Baker Street, London, we provide tailored Mounjaro Safety Profiles, including kidney and liver tests. This guide explains how Mounjaro works, its potential effects on kidneys, and which tests you may need.
What is Mounjaro?
Mounjaro (tirzepatide) is part of a class of medicines called GLP-1 receptor agonists. These drugs:
- Help lower blood sugar levels
- Reduce appetite and support weight loss
- Improve insulin sensitivity
Because of these benefits, Mounjaro is growing in popularity. However, it is important to monitor how the drug interacts with vital organs.
Can Mounjaro affect the kidneys?
For most patients, Mounjaro is safe and effective. However, there are certain kidney-related risks worth knowing:
- Dehydration stress: Some people experience nausea, vomiting, or diarrhoea. These symptoms can reduce fluid levels, straining the kidneys.
- Changes in kidney markers: Rarely, Mounjaro may cause shifts in creatinine or urea, which measure kidney function.
- Higher risk in existing kidney disease: If you already have chronic kidney disease, careful monitoring is recommended.
In most cases, these issues are preventable with regular blood and urine tests.
Which kidney tests are important?
At MDC, our kidney function profile includes:
- Creatinine: a measure of how efficiently kidneys filter waste.
- eGFR (estimated glomerular filtration rate): shows overall kidney performance.
- Urea: checks how well waste products are removed.
- Electrolytes (sodium, potassium, chloride): monitors essential balance.
These are performed with a simple blood and urine test, with results available the same day.
