Well, that did take a bit longer than expected. Energy drinks can cause heart problems and even death. That much was already known. But now it appears that the consumption of four to five energy drinks daily for three weeks can already cause painful and potentially fatal hepatitis.
Laboratory studies showed transaminitis (elevation of certain enzymes in the liver) and evidence of chronic Hepatitis C infection. A liver biopsy showed severe acute hepatitis with bridging necrosis and marked cholestasis (reduction or even stoppage of bile flow).
The development of acute hepatitis in this patient was likely secondary to excessive energy drink consumption. Energy drinks should be considered when patients arrive with acute hepatitis.
