What is a potential cause for a tortuous aorta in the elderly?

A tortuous aorta, characterized by an abnormal twisting or elongation of the aorta, is often observed in the elderly and is primarily attributed to the normal aging process. As individuals age, the connective tissues in the body, including those in the blood vessels, undergo changes that can lead to stiffness and decreased elasticity. These changes can result in structural deformities such as a tortuous aorta.

The aging vascular system often faces increased pressure due to risk factors such as hypertension and atherosclerosis, further contributing to alterations in the structure of the aorta. Unlike options that suggest physical attributes related to breathing or lifestyle choices, the normal physiological changes that occur over time are the most direct and significant contributors to the development of a tortuous aorta in older adults.
