I take vitamin D. Sometimes high cholesterol can run in the family.
I'm assuming this is me not taking care of myself.
Don't assume.
Once you are on those, docs usually want to work up blood tests every six months to keep up to date with your needs and the effectiveness of the dosage.
Alter your diet a bit and watch for your next bloodwork.
I took all mine a little early, but I felt a need after becoming quite hot outside.
I get the same results these days. Lots of cholesterol, but just a little too much of the bad kind. Doc says to eat more greens, certain grains and get more exercise.
I suck at diets.
Yeah, me too!
But I am not talking about trying to stick to some published diet, other than what your life experience and reading have taught you. More of this, less of that, try not to eat as much of "bad" as before.
Try to eat better and
things either get better or no worse. Don't skip your bloodwork. I would add, "FIGHT!!" but most of that has left me in recent years. Maybe try anyway.
Even simple things can work, like I almost doubled the quantity of nuts I eat and my cholesterol went down. Nuts are often salted so you have to watch that, but you already know all this.
Small changes toward balance anyone can do.
Oh, and try to do enough of what the doctor says to make him want to pat himself on the back.
Kidding!
