Deaths from liver disease have increased sharply in recent years in the United States, according to a study published in the British Medical Journal. Cirrhosis-related deaths increased by 65 percent from 1999 to 2016, and deaths from liver cancer doubled, the study said. The rise in death rates was driven predominantly by alcohol-induced disease, the report said. Over the past decade, people ages 25 to 34 had the highest increase in cirrhosis deaths — an average of 10.5 percent per year — of the demographic groups examined, researchers reported. The study suggests that a new generation of Americans is being afflicted “by alcohol misuse and its complications,” lead author Elliot Tapper, a liver specialist at the University of Michigan, said. Tapper said people are at risk of life-threatening cirrhosis if they drink several drinks a night or have multiple nights of binge drinking — more than four or five drinks per sitting — per week.
