A young man who consumed two litres of energy drink a day was admitted to intensive care with severe heart failure.
According to a leading medical journal, the university student landed himself in hospital after drinking four cans of energy drink per day.
The 21-year-old spent nearly two months in intensive care due to heart failure, with the British Medical Journal stating this was âpotentially related to excessive energy drink consumptionâ in a report.
According to the report, the man drank four 500ml energy drinks every day for two years, becoming so ill that medics thought he might require an organ transplant.
The patient went on to describe his medical episode as ‘traumatising’, eventually seeking medical help after he suffered from weight loss and shortness of breath for roughly four months.

Doctors performed blood tests, scans, and ECG readings, and found that he had both kidney and heart failure â however, the kidney failure was discovered to be linked to a previously undiagnosed condition.
Each energy drink the man was consuming contained around 160mg of caffeine, and medics said that âenergy drink-induced cardiotoxicityâ was the most likely cause of the severe heart failure.
In the report, the authors from Guyâs and St Thomasâ NHS Foundation Trust wrote: âWe report a case of severe biventricular heart failure potentially related to excessive energy drink consumption in a 21-year-old man.”
They said the conclusion to their report âadds to the growing concern in the literature about the potential cardiotoxic effects of energy drinksâ, adding that the man’s heart function seems to have returned to normal nine months later but with âmildly impaired functionâ.

The recovered patient added his own thoughts to the article, saying: âWhen I was drinking up to four energy drinks per day, I suffered from tremors and heart palpitations, which interfered with my ability to concentrate on daily tasks and my studies at university.
âI also suffered from severe migraine headaches which would often occur during the periods when I did not drink energy drink; this also restricted my ability to perform day-to-day tasks and even leisurely activities such as going to the park or taking a walk.”
He added: âI think there should be more awareness about energy drinks and the effect of their contents.
âI believe they are very addictive and far too accessible to young children. I think warning labels, similar to smoking, should be made to illustrate the potential dangers of the ingredients in energy drink.â
