I am 53 year old female. I have 100 % blocked carotid artery on my left and it was 80% blocked on my right side. I had surgery on the right side Oct 2014. I went back for an ultra sound today at a health screening and was told it is 50% blocked. I take Crestor 10 MG a day that was just increased recently like a month ago was on 5 mg. I also take metropiraol one at night and one at morning. I just don t understand I recently lost 15 lbs I weigh now 157 I exercise daily for a half hour and incorporated a 10 minute abs to my exercise. Why is my body producing so much plaque?
