Your May LDL is 135 vs April 75.
May HDL is 43 vs April 39.
1. April LDL 75 - did you have this number with Statin intake or without? If with, then it will be likely this low number (75 looks like a 'statined' number for your case).
2. May LDL 135 - I assume this higher number is without taking statin from your text.
In my experience, a diet will take about 3 months to see the 'more true' effects. Your current one-month only into your clean diet maybe too short to conclude much (and therefore, it you have not been taking statin before your clean diet, then you should not start / re-start your statin (else you can't really see whether clean diet really working over longer term for you or not). The statin decision may be made after three months of clean diet.)
LDL135 is not that high to carry in your system for another 2 months (of clean diet). Probably after 3 months of clean diet and this number still doesnt improve, then talk to doctor about your statin decision.
*pls do not suka suka start / stop statin coz this will cause harm to your body as your system will get confused of suddenly more / less cholesterol and the organs may give up auto adjusting / mal-function and lead to more serious metabolic syndrome.
**with a clean diet for 3 months, my LDL managed to drop about 20%. Since diet proved working for me, I continue with it (most of the time) without statin. Meaning if it didn't work, then I would have started statin (which was the agreement with my doctor to go without statin for the 3-month clean diet trial).
Clean diet may or may not work coz of individual's 'cholesterol production' condition in the system (but will work most of the time). So, be patient to dong three months to see your own 'verdict'.
