A 21-year-old university student suffered heart failure after "excessive" consumption of energy drinks, a medical journal report has revealed.

The young man ended up in intensive care after he drank up to four 500ml drinks — a total of 640mg of caffeine — per day for two years.

‘I suffered from tremors and heart palpitations,’ said the patient, ‘I also suffered from severe migraine headaches.’

He sought help after his ill health, including shortness of breath and lethargy, brought his university studies to a halt for three months.

Medics found he had heart and kidney failure — the latter linked to a long-standing, previously undiagnosed condition.

The report’s authors, from Guy’s and St Thomas’ NHS Foundation Trust, called the case ‘severe biventricular heart failure potentially related to excessive energy drink consumption’.

And doctors treating him said his energy drink habit ‘was felt to be the most likely cause’.

The student was in hospital for 58 days, including a ‘traumatising’ ICU stint.

With his heart function now just ‘mildly impaired’ after nine months, he has called for warning signs on the ‘addictive’ beverages.
