Adherence
Smoking reduces HDL-C concentrations by approximately 6%, and smoking cessation reverses this reduction, raising HDL-C by about 0.10 mmol/L.
Quit smoking. Your HDL-C will likely increase by about 0.10 mmol/L. Be aware that nicotine replacement therapy (patches/gum) might delay this HDL recovery; stopping the nicotine itself allows HDL to normalize. The benefit of quitting outweighs potential weight gain.
GoodSupportsHIGH confidence
A meta-analysis carried out almost 25 years ago indicated that smoking has a strong independent effect on plasma HDL-C levels with smokers having on average 6 % lower HDL-C concentrations compared to non-smokers... A meta-analysis of 27 studies incorporating over 6,000 subjects indicated that HDL-C increased by 0.10 mmol/L after smoking cessation
Why this rating
