Negative Side-Effects From A Single Energy Drink

A new study has found that consuming just one energy drink a day could increase the risk of a heart attack and stroke within 90 minutes, with researchers saying the drinks narrow blood vessels – which can restrict the flow of blood to vital organs.

While previous studies have found a link between energy drinks and stomach, nerve and heart problems, the new findings from the University of Texas in Houston are among the first to shed light on the potential increased risk of heart attack and stroke.

The research examined 44 students from McGovern Medical School at UTHealth, with all participants in their 20’s and classed as ‘healthy’ and were non-smokers.

They tested the function of endothelial, the layer of cells lining the surface of blood vessels, the dysfunction of which has been shown to be an indicator of heart attacks as arteries aren’t able to fully dilate.

Participants’ endothelial function was tested before they drank a 24-ounce energy drink and again 90 minutes after they had finished the drink. Within that time, the internal diameter of blood vessels had, on average, been decreased by nearly half.

Dr John Higgins, a professor of medicine at the McGovern School, said: “As energy drinks are becoming more and more popular, it is important to study the effects of these drinks on those who frequently drink them and better determine what, if any, is a safe consumption pattern.”
