Insulin Resistance Reason Smoking Increases Risk of Heart Disease

The results of a study conducted by researchers at Charles Drew University of Medicine and Science in Los Angeles and Western University of Health Sciences in Pomona are in, and shed new light on why smoking and heart disease are related. Nicotine, a highly-addictive substance in cigarettes, promotes insulin resistance, which is a pre-diabetic condition. People with insulin resistance have blood sugar levels that are higher than normal, and diabetes is recognized as a risk factor for heart disease.

Even though individuals who are insulin resistant have blood sugar levels that are elevated, their levels aren’t high enough to cause diabetes. People who smoke tend to have higher rates of diabetes, but research hasn’t yet determined whether smoking is the cause or other factors are responsible.
