More people are landing in the hospital after consuming energy drinks, a report released Tuesday shows.
Hospitalizations in the United States tied to energy drinks have jumped tenfold, to 13,114 in 2009, according to the report from the Substance Abuse and Mental Health Services Administration.
The agency, which is part of the Department of Health and Human Services, said 44 percent of the visits involved people who had combined energy drinks with alcohol, pharmaceuticals or illicit drugs, Reuters reports.
"They come to the emergency room... it usually has to do with the chest, chest pain, that kind of thing," said Dr. Cathleen Clancy at the National Capital Poison Center.
Doctors are alarmed at the health risks, including hypertension, dehydration, sleeplessness and nervousness.
The packaging leads consumers to think the drinks are nutritious. But doctors warn energy drinks can contain as much caffeine as five cups of coffee.
