Welcome to HCM.
Your Lipid profile
and fasting blood sugar levels are absolutely normal.
You can stop using Rosuvastatin
5 mg . But before stopping it completely, you need to see whether your body can maintain the cholesterol
levels with in normal range without the medicine. For that you need give it a trial.
Stop using medicines for a period of 10 days and then repeat the lipid profile. If the result comes out normal , you can stop taking the medicine completely. I dont think you need to continue the medicine, as you are maintaining a healthy life style. Keep it going and enjoy the life to the fullest.
Wish you a healthy life.
