Yes, H. pylori can cause elevated liver enzymes.


Typically, the range for normal aspartate transaminase (AST) is between 10 to 40 IU/L, and alanine transaminase (ALT) between 7 to 56 IU/L.

A recent study of 107 patients showed that their average AST levels were 61 IU/L, with ALT levels at 48 IU/L.

After the H. pylori were eliminated, the AST levels decreased by 6 IU/L and ALT levels decreased by 8 IU/L.

The results suggest that *H. pylori * infection plays a role in raising the level of liver enzymes.
