Ok, thank you.
So it seems that your overall cholesterol as well as triglycerides are very high.
Beer can raise your cholesterol, specifically it can raise triglycerides (which is a measure of fat in the blood), however, it will not raise your cholesterol to the level where you are currently at.
I don't think there any specific urgency to start taking Simvastatin right away. I understand that you are only 32 and that Simvastatin is a life-long drug so you can try to change your diet, however, I don't think you will be able to significantly lower your cholesterol with diet/exercise alone. Eventually I do think you will need to go on a cholesterol reducing agent. But to be fair, it would be no problem to try diet/exercise routine for 3 months prior to going on the medication.
It sounds that you eat rather healthy. What happens is that our bodies make cholesterol on top of what we digest and some people over-produce their own cholesterol which is why exercise and diet is not always beneficial. All statin drugs, including Simvastatin, not only lower cholesterol but also stabilize plaques which form in the arteries secondary to high cholesterol. A heart attack happens when a plaque which has been building in the artery ruptures and a blood clot travels down a narrow artery and eventually gets stuck. One of the roles of the statin drugs is to actually stabilize that plaque and reduce a chance of it rupturing.
Not everyone who has heart attacks has high cholesterol such as the case with your dad.
In terms of dietary modifications - definitely try to reduce, if not eliminate, your beer intake. Try to avoid red meats and eat more chicken and fish. Avoid dairy products high in fats (sour cream, mayo, whipped cream, butter, etc). You can take Fish oil supplement (which helps with lowering triglycerides and is more natural). Use olive oil or grape seed oil for cooking. And, of course, eat lots of fruits and vegetables.
After implementing these changes, you can repeat your cholesterol in 3 months to see if there has been any change. If there has been a change, you can probably continue with diet/exercise to see if the levels improve even further, if not, you should take Simvastatin.
