Article Commentary: “Obesity-Associated Organ Damage and Sympathetic Nervous Activity: A Target for Treatment?”
Adeola Olowu, MD
The authors of this review focused on obesity and a potential target for treatment. Obesity and increased body mass index are risk factors for diseases such as stroke, cardiovascular disease, and other medical conditions. This brief review focused on cardiovascular studies, studies demonstrating an association between weight gain with blood pressure, cardiovascular abnormalities, renal function, and endothelial dysfunction and its relationship with biochemical sympathetic nervous activity.
Being overweight or obese is a growing medical condition worldwide. Obesity is unique to other cerebrovascular risk factors because it may be the sole risk factor an individual may have for quite some time. However, the lack of other cerebrovascular risk factors such as hypertension and diabetes does not make being overweight or obese harmless. The studies reviewed showed hypertension prevalence to be at least 16% higher in the obese population compared to the normal-weight population in the United States. Pre-hypertension was found in approximately 40% of obese men and 30% in obese women in China. Observational studies demonstrated elevated plasma norepinephrine and increased MSNA with weight gain.
