Liver injury: It's difficult today you have a liver injury. There are many insults that can cause liver enzymes to go high temporarily, like an infection or even some medications. But after a few days, they should fall back down to normal. One isolated value isn't as concerning as a more longstanding trend. It's unlikely your coffee caused increased liver enzymes (unless it was more Bailey's than coffee.)
