heya!
there's a similar thread here not long ago, High Blood Pressure at 31, who am i kidding.
There are some useful insights shared there, hopefully you can go through it when you got the time.

For me, the general public punya response to these sort of thing (stroke/high bp) is:
1. kurangkan garam/less salty <- yea, sounds right BUT you got time to cook your own meals 3times/day? eating out, the salt portion is almost entirely out of your hands
2. less caffeine/kopi <- for me, i have stopped 3-in-1/2-in-1s, i still take nescafe/kopi tarik
3. this one konfem 10/10 will say - EXERCISE/DIET/LOSE WEIGHT <- just sweat it out every day is good enough, no need hit the gym also can sweat one, go for runs (the air guaranteed fresher than aircon gym)/ go for badminton/pickleball sessions (or like me, kena covid bedridden 1 week, lose almost 10kg <- PLS DON'T)
