He was healthy and fit at 54, an avid runner with no vices \u2014 he didn\u2019t smoke, drink or do drugs. So when he suddenly experienced left-sided weakness, numbness and difficulties with balance, walking, swallowing and speech, a family member rushed him to a nearby stroke clinic.<\/p>\n

\u201cHis blood pressure was sky high \u2014 about 254 over 150 millimeters \u2014 yet when you looked at him you\u2019ve never know it, because he looked so well. That\u2019s why we call hypertension the silent killer,\u201d said Dr. Sunil Munshi, a consulting physician at Nottingham University Hospitals NHS Trust in the United Kingdom.<\/p>\n

Munshi is the senior author of a case report about the man, a warehouse worker from Sherwood, Nottingham, whose name was withheld to protect his privacy. The paper was\u00a0published Tuesday\u00a0in the journal BMJ Case Reports.<\/p>\n

Normal blood pressure for adults\u00a0is less than 120 over 80 mm HG (millimeters of mercury). Blood pressure of 180 over 120 or higher is considered a medical crisis that requires immediate emergency care.<\/p>\n

\u201cHis left side was numb, and scans showed he had a stroke in the deeper part of the brain, the thalamus, which explains the unsteadiness,\u201d Munshi said. \u201cHe was admitted, and we treated him with five different medications until his blood pressure dropped to 170.\u201d<\/p>\n

Back at home again, the man\u2019s blood pressure continued to climb, reaching 220 despite numerous drugs. Munshi and his team searched for answers for weeks, running extensive tests that turned up negative. Then one day the man told Munshi about his energy drink habit.<\/p>\n

\u201cEach day he consumed eight highly potent energy drinks to stay alert for his job \u2014 two cans at four different times during the day,\u201d Munshi said. (The brand name was withheld from the study.) \u201cEach of the drinks contained 160 milligrams of caffeine. Suddenly the diagnosis was clear.\u201d<\/p>\n

Some energy drinks can have up to 500 milligrams of caffeine, compared with 30 milligrams in tea and 90 milligrams in coffee, said study first author Dr. Martha Coyle, a resident doctor at Nottingham University Hospitals NHS Trust.<\/p>\n

\u201cIn the UK, guidelines suggest 400 milligrams of caffeine a day, between two and four cups,\u201d Coyle said. \u201cThis gentleman was consuming 1,200 to 1,300 milligrams, three times the amount.\u201d<\/p>\n

The US Food and Drug Administration also recommends no more than 400 milligrams a day.<\/p>\n

Just weeks after stopping his consumption of the energy drink, the man\u2019s blood pressure returned to normal. Today, years after the incident, he is healthy but still lives with the aftermath of his stroke.<\/p>\n

\u201cI obviously wasn\u2019t aware of the dangers drinking energy drinks were causing to myself,\u201d the man told his doctors. \u201c(I) have been left with numbness (in my) left hand side hand and fingers, foot and toes even after 8 years.\u201d<\/p>\n

Combinations of ingredients \u2018cause havoc\u2019<\/strong><\/p>\n

It\u2019s not just high levels of caffeine. Today\u2019s energy drinks also contain blood pressure boosting ingredients such as the amino acid taurine, Munshi said.<\/p>\n

\u201cEnergy drinks that contain caffeine plus taurine produce significantly higher blood pressure than caffeine alone,\u201d he said. \u201cThey also contain high levels of glucose \u2014 we know sugar damages the blood vessels in diabetes which leads to heart damage.\u201d<\/p>\n

Energy drinks also typically contain ginseng, which impacts metabolism, and guarana, a plant thought to contain caffeine at twice the concentration of a coffee bean, according to the study. Milder stimulants such as theophylline, found in cocoa, and theobromine, found in tea, are often included as well, Coyle said.<\/p>\n

Such energy drinks can cause cardiac arrhythmias, damage the endothelium, the tissue that lines blood vessels, and aggregate blood platelets, Munshi said.<\/p>\n

\u201cWhen platelets are aggregated, especially in the setting of high glucose, they can produce blood clots,\u201d he said. \u201cYoung people are often willing to try energy drinks, especially in combination with other drugs such as cocaine or methylamphetamine, which have similar effects, and all of these drugs together can cause havoc.\u201d<\/p>\n

Medical literature is full of examples of the harms of energy drinks, so this case, while startling, is not an isolated event, Munshi said.<\/p>\n

\u201cWe have seen other patients who developed an irregular heartbeat, what we call atrial fibrillation,\u201d he said.\u201d Another patient developed an intracellular hemorrhage in the brain, while yet another patient had a stroke in the brain due to a blood clot.\u201d<\/p>\n

Munshi believes doctors need to become more aware of the impact of energy drinks and ask about use during regular checkups, \u201cespecially when people come at a younger age with cardiovascular problems or strokes.\u201d<\/p>\n

\u201cThe nature of these drinks is changing. They have become more and more dangerous and more potent,\u201d he added. \u201cWe propose increased regulation of energy drink sales and advertising campaigns, which are often targeted at younger ages.\u201d<\/p>\n<\/div>\n
