title: Hypertension in a young boy: an energy drink effect.
abstract: BACKGROUND
  Use of energy drinks has significantly increased in recent times. Besides athletes, teenagers and students are among the most common consumers. However, popularity is also increasing among the younger and older age groups. Most of the users believe that they are a good source of instant energy and are unaware of its high Caffeine content resulting in harmful effects on health.
  
  
  METHODS
  We report the case of a young boy who presented with palpitations and high blood pressure as a result of energy drinks usage. He had been consuming a "Sting" energy drink on regular basis while studying for long hours during his O' level Exams. His medical examination revealed Sinus tachycardia and high blood pressure. Rest of the examination and lab workup was within normal limits. His pulse and blood pressure returned to normal range after discontinuing Sting usage.
  
  
  CONCLUSIONS
  Several studies have reported numerous health hazards including cardiac effects associated with energy drinks. Warning labeling should be done on these drinks regulating the content of Caffeine and its harmful effects on health.
