The question is when was the blood drawn for your second test. See, what doctors don't tell you but you should know is that you are supposed to have the blood drawn for a cholesterol test
no earlier than 8 hours after eating. That means that if you had breakfast at 8 and had blood drawn at 10, your test will give you high numbers.
If, however, you were fasting this time before you had your blood drawn, the results are VERY high. Cut back on french fries. Cut back on sodas. Cut back on bacon for breakfast. Go on an oatmeal diet for a few weeks (oatmeal for breakfast and dinner), and go for a walk after classes. Then get your cholestserol checked again, this time after having eaten nothing for 8 hours before getting the blood drawn.
Your cholesterol should be between 120 and 160, and the lower the better.
Hope this helps.
