Does extremely low cholesterol from meds cause health problems?

My lab link

Chart below shows official guidelines advising getting

 LDLc below 55 and nonHDLc below 80

for extreme high risk patients

My LDLc is 46 and nonHDLc is 69

I am type 2 diabetic and have been on Atkins or LCHF since 2011

Before this last lab I was taking:

Atorvastatin 5 mg 

Zetia full dose

I just came home from 3 months of travel. 

I gained three pounds on the trip.

My point here is that without taking a very expensive PCSK9

I was able to achieve the lowest targets in the guidelines.

As I was very aggressive in treating subclinical atherosclerosis

in 2010.

Below are excerpts from my book:
