Atherosclerosis is considered to be regressable, especially in its early stages and when individuals adopt significant lifestyle changes. This progressive disease is characterized by the buildup of plaques within the arterial walls, which can lead to cardiovascular issues. However, research indicates that interventions such as lifestyle modifications—like improved diet, increased physical activity, smoking cessation, and weight loss—can lead to a reduction in the size of atherosclerotic plaques and an improvement in endothelial function.

This regression involves complex biological processes where healthy behaviors can help stabilize or even reduce lesion size in the arteries. Furthermore, certain medications (like statins) can provide additional benefits in managing cholesterol levels and reducing inflammation, contributing further to the regression of atherosclerotic plaques.

Therefore, the notion that atherosclerosis is regressable highlights the potential for positive health outcomes through proactive and sustained changes in lifestyle and medical management, particularly in individuals who take action during the early stages of the disease.
