This is far from the only example of a person landing in hospital after consuming too many energy drinks, but research on the topic still remains scarce. He is now avoiding energy drinks, the case report stated, something doctors believe is contributing to his improved heart function. Although he is on the mend now, he will have to have ongoing cardiology, renal and urology follow-ups, and doctors suspect he may require “future bladder reconstruction” and possible a kidney transplant at some point. The 21-year-old was eventually discharged from hospital 58 days after he originally came in with his mysterious symptoms.

“Given the history of chronic energy drink consumption, lack of significant past medical or family history, cardiac imaging findings and improvement with ceasing intake, energy drink-induced cardiotoxicity was felt to be the most likely cause,” the case report stated. The patient stated that “the experience was extremely traumatizing,” partly because he was suffering from delirium and memory issues, meaning he would wake in the ICU with no idea why he was there.ĭoctors theorized that he had been experiencing low cardiac output for months. Fluids were also building up in his knees and abdomen.Ī chest X-ray showed that his heart was enlarged, and an ultrasound found both his kidneys and liver were enlarged as well.Īccording to the case study, the situation was dire, and he was taken to the ICU of another hospital to receive more specialized care. When there was little improvement in his renal function, doctors examined him further, and discovered he was “in decompensated cardiac failure”, which means some change in his heart was interfering with its ability to pump or accept blood. The situation worsened after doctors attempted to treat the issues with his kidneys. In a statement provided with the case study, the patient, who is not identified by name, wrote that when he was not consuming these energy drinks, he would suffer “from severe migraine headaches.” “Retrospectively, the patient recalls occasional symptoms of dyspepsia, tremor and a racing heartbeat but without seeking medical review,” the case study stated. The drinks had around 160 mg of caffeine each. Specifically, he had been downing “an average of four 500 mL cans per day for approximately two years.” However, he explained that he did consume energy drinks on the regular. He also did not consume alcohol or use drugs, he told doctors. “He was an ex-smoker, having stopped three years earlier.”

“There was no significant past medical history and family history was not suspicious for cardiomyopathy or sudden cardiac death,” the case report stated. He also had felt so ill over the last three months that it had disrupted his university studies. He told doctors that he had been experiencing progressively shorter breath over the past four months, as well as weight loss and a general feeling of unwellness. While it was apparent that he was in need of surgery, what was less apparent was the cause of his condition. When doctors investigated further, they found that in both of his kidneys, urine was unable to drain into the bladder. man who was first admitted to hospital with shortness of breath and a swelling in the abdomen.Īfter he was inspected by doctors, he was quickly found to be experiencing kidney failure, and was unable to fully empty his bladder, the case study says. The case study, published in BMJ Case Reports on Thursday, explains the unusual case of a U.K. A new case study describes a rare case of severe heart failure in a 21-year-old man after he drank multiple energy drinks daily for two years - revealing the potential dangers of excessive consumption of these beverages.
