The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

The objective of the study was to ascertain whether statin use adversely affects asthma. The study included 24 patients who were on statin therapy and 26 controls, not on statin therapy.

The study found after six months:
(a) There was a significant 3% worsening of forced expiratory volume in 1 second (a worsening of lung function) for the statin group compared with the controls.
(b) 40% more patients in the statin group needed increased asthma medication compared with the controls.
(c) 63% more patients in the statin group used albuterol more frequently compared with the controls. (Albuterol is used to prevent and treat wheezing, difficulty breathing and chest tightness caused by lung diseases).
(d) 33% more patients in the statin group had more nocturnal awakenings compared with the controls.
(e) 34% more patients in the statin group had to see the doctor more frequently for acute asthma.

This study demonstrates that statin use adversely affects asthma.
