People of all ages who have high levels of cholesterol, 225+, lower with family histories or the trio, are advised to take a medication now. There are some people who have a reaction to the statins, even to the other types such as Zetia. So they will test and want to know your individual tolerance for the medication, whichever one you're prescribed. Insurance companies want everyone to take the generic statin--because it's cheap of course.
My son-in-law, only 37, takes his statins regularly, along with blood pressure meds. His mother and father have heart issues that are controlled. Cholesterol over 200 usually causes the doctor to advise the use of a drug. Like all medication it's a balance between the demonstrated benefit, i.e. fewer "events"--medical talk for heart issues, against the risks. You'll be tested on a regular basis, more frequently at first, for any adverse reactions that are only revealed in blood work. Some people, me included, have had reactions to statins, so they are given things like Zetia, my drug. You'll also get advised to take it if you have the trio, mild high blood pressure, less than 150/80, but higher than 120/70, elevated cholesterol over 200, and elevated fasting blood glucose--100-up to-125, i.e pre-diabetes.
I'd advise, 1) relax, it's just part of growing up/mature/old--however you regard that process, and 2) in addition to the meds, keep up your exercises, especially pushing away from the table
, and diet. If you are over weight, a loss of 10 or more pounds may control all three issues without anything further. If not, well, you're still above ground, so enjoy life.
