Health News: Just one energy drink, designed to increase stamina and improve physical performance, can cause 'serious heart conditions,' according to a new study.

According to Adelaide Now, the study has prompted Australian Medical Association state president Dr Andrew Lavender to warn people to limit their consumption of energy drinks to one a day until further urgent research into long-term consumption of the drinks is complete.

The study by the University of Adelaide, Royal Adelaide Hospital and Cardiovascular Research Centre, found 'common energy drinks do trigger significant changes, including a rise in blood pressure, increased stickiness of blood and decreased blood vessel function'.

"These measures could potentially lead to serious heart conditions in otherwise fit and healthy individuals," News.com.au quoted study author and Physiology Senior Research Officer Dr Scott Willoughby as saying.he study has been published in the prestigious American Journal of Medicine.
