Stroke is one of the most common causes of death worldwide. However, scientists insist that this condition can be avoided and prevented, especially by steering clear of triggers. While the risk factors for stroke are widely recognized, the triggers are often not discussed. One such trigger is energy drinks, which can lead to irregular heartbeats and may increase the likelihood of stroke by five times, according to Russia Today.
Energy drinks contain caffeine disguised in forms such as guarana, which has twice the amount of caffeine found in coffee beans. Although caffeine consumption is generally considered safe, adverse events can occur after consuming high doses of this stimulant. Energy drinks contain large amounts of caffeine and sometimes other stimulants. Some individuals who consume them end up in the hospital suffering from stroke or severe brain bleeding, typically young and healthy individuals in their thirties and forties.
Stroke occurs after consuming energy drinks and is a result of Reversible Cerebral Vasoconstriction Syndrome (RCVS). This condition causes a sudden spasm of blood vessels in the brain, which can either restrict blood flow to the organ or lead to bleeding. The key symptom of RCVS that is detected is a sudden headache that intensifies rapidly within a few minutes.
The exact reason energy drinks trigger RCVS remains unclear, but it is believed that excessive caffeine consumption could be a contributing factor. Furthermore, excessive caffeine intake can significantly increase the amount of calcium released inside heart cells.
Caffeine consumption greatly elevates the risk of atrial fibrillation or irregular heartbeats. According to the Journal of Geriatric Cardiology: "Atrial fibrillation is associated with a fivefold increased risk of ischemic stroke, stroke recurrence, and death. Anticoagulant treatment may reduce the risk of recurrent stroke by about 60%."
