Yesterday my wife went to the doctor for her three month cholesterol level screening. When I talked with her she told me that the doctor increased her cholesterol dose and her blood pressure medicine. My wife hasnt always had these problems because she used to be more active in her daily life. The problem my wife and I have is being too lazy to get off the couch and exercise. I and my wife both know that all we have to do is take a 30 minute walk a day and this would lower her cholesterol and blood pressure. Cholesterol is a fatty substance in your blood. The two types of cholesterol are low density lipoprotein (LDL) and high density lipoprotein (HDL).
