Can Mounjaro Cause Liver Damage?
Your liver plays a vital role in processing medications, filtering toxins, and managing metabolism. Some users of Mounjaro report elevated liver enzymes, and though rare, cases of liver stress or injury can occur – especially with long-term use or when combined with other medications or alcohol.
That’s why routine liver monitoring is key to staying safe.

What Liver Tests Should You Do?
Our Mounjaro Safety Panel includes a comprehensive liver profile:
| Test Name | What It Measures |
| ALT & AST | Enzymes that indicate liver cell damage |
| ALP (Alkaline Phosphatase) | Levels may rise with bile duct issues or liver inflammation |
| GGT | Sensitive to alcohol and medication-induced liver stress |
| Total Bilirubin | High levels may suggest liver dysfunction or bile blockage |
| Albumin & Total Protein | Reflects the liver’s synthetic function |
These results give a complete picture of how your liver is coping – even before you feel any symptoms.

July 2025 Update: What New Research Says About Mounjaro & the Liver
As of July 2025, several new studies have provided more insights into how Mounjaro (tirzepatide) may impact liver health.
Mild liver enzyme rises are still the most common finding.
Recent papers in The Journal of Diabetes & Metabolism reviewed over 5,000 patients. They found that while small increases in ALT and AST can occur, serious liver injury remains extremely rare.
Fatty liver improvements in many patients.
Interestingly, some people taking Mounjaro for weight loss showed better liver ultrasound results. This is likely because weight loss itself reduces liver fat.
Who needs to be cautious?
Patients with pre-existing liver disease (like cirrhosis or hepatitis) are still advised to have regular blood tests. This ensures any subtle changes are picked up early.
At Marylebone Diagnostic Centre, we continue to monitor these trends closely. Our Liver Function and eGFR panels give you quick answers – often with same day results in London.
If you have questions or want personalised advice, we’re here to help.
