He was healthy and match at 54, an avid runner with no vices — he didn’t smoke, drink or do medication. So when he immediately skilled left-sided weak spot, numbness and difficulties with stability, strolling, swallowing and speech, a member of the family rushed him to a close by stroke clinic.
“His blood pressure was sky high — about 254 over 150 millimeters — yet when you looked at him you’ve never know it, because he looked so well. That’s why we call hypertension the silent killer,” stated Dr. Sunil Munshi, a consulting doctor at Nottingham University Hospitals NHS Trust within the United Kingdom.
Munshi is the senior writer of a case report in regards to the man, a warehouse employee from Sherwood, Nottingham, whose title was withheld to guard his privateness. The paper was published Tuesday within the journal BMJ Case Reports.
Normal blood pressure for adults is lower than 120 over 80 mm HG (millimeters of mercury). Blood strain of 180 over 120 or greater is taken into account a medical disaster that requires fast emergency care.
“His left side was numb, and scans showed he had a stroke in the deeper part of the brain, the thalamus, which explains the unsteadiness,” Munshi stated. “He was admitted, and we treated him with five different medications until his blood pressure dropped to 170.”
Back at residence once more, the man’s blood strain continued to climb, reaching 220 regardless of numerous medication. Munshi and his group looked for solutions for weeks, working intensive checks that turned up unfavorable. Then in the future the man instructed Munshi about his energy drink behavior.
“Each day he consumed eight highly potent energy drinks to stay alert for his job — two cans at four different times during the day,” Munshi stated. (The model title was withheld from the research.) “Each of the drinks contained 160 milligrams of caffeine. Suddenly the diagnosis was clear.”
Some energy drinks can have as much as 500 milligrams of caffeine, in contrast with 30 milligrams in tea and 90 milligrams in espresso, stated research first writer Dr. Martha Coyle, a resident physician at Nottingham University Hospitals NHS Trust.
“In the UK, guidelines suggest 400 milligrams of caffeine a day, between two and four cups,” Coyle stated. “This gentleman was consuming 1,200 to 1,300 milligrams, three times the amount.”
The US Food and Drug Administration additionally recommends not more than 400 milligrams a day.
Just weeks after stopping his consumption of the energy drink, the man’s blood strain returned to regular. Today, years after the incident, he’s healthy however nonetheless lives with the aftermath of his stroke.
“I obviously wasn’t aware of the dangers drinking energy drinks were causing to myself,” the man instructed his docs. “(I) have been left with numbness (in my) left hand side hand and fingers, foot and toes even after 8 years.”
It’s not simply excessive ranges of caffeine. Today’s energy drinks additionally comprise blood strain boosting elements such because the amino acid taurine, Munshi stated.
“Energy drinks that contain caffeine plus taurine produce significantly higher blood pressure than caffeine alone,” he stated. “They also contain high levels of glucose — we know sugar damages the blood vessels in diabetes which leads to heart damage.”
Energy drinks additionally sometimes comprise ginseng, which impacts metabolism, and guarana, a plant thought to comprise caffeine at twice the focus of a espresso bean, in line with the research. Milder stimulants similar to theophylline, present in cocoa, and theobromine, present in tea, are sometimes included as properly, Coyle stated.
Such energy drinks may cause cardiac arrhythmias, damage the endothelium, the tissue that traces blood vessels, and mixture blood platelets, Munshi stated.
“When platelets are aggregated, especially in the setting of high glucose, they can produce blood clots,” he stated. “Young 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.”
Medical literature is filled with examples of the harms of energy drinks, so this case, whereas startling, shouldn’t be an remoted occasion, Munshi stated.
“We have seen other patients who developed an irregular heartbeat, what we call atrial fibrillation,” he stated.” Another affected person developed an intracellular hemorrhage within the mind, whereas yet one more affected person had a stroke within the mind as a consequence of a blood clot.”
Munshi believes docs have to turn out to be extra conscious of the affect of energy drinks and ask about use throughout common checkups, “especially when people come at a younger age with cardiovascular problems or strokes.”
“The nature of these drinks is changing. They have become more and more dangerous and more potent,” he added. “We propose increased regulation of energy drink sales and advertising campaigns, which are often targeted at younger ages.”
