I have high cholesterol and triglycerides for past over 25 years, but without having posed any issue. I have no history of BP or hypertension or sugar. Still recently, I had a stroke. Fortunately, I could be attended in ICCU and a clot could be identified and diluted thru medication. Apart from a memory loss of few hours, there was no adverse effect. My query is - despite having no history of any BP, Sugar, HT etc. How could a stroke got encountered by me?
