What might cause diminished peripheral pulses in older adults?

Diminished peripheral pulses in older adults are often a result of physiological changes related to aging, notably the thickening of the arterial wall. As individuals age, the arteries undergo a process called arteriosclerosis, where they lose elasticity and become thicker and stiffer. This thickening can lead to narrowing of the arteries, which restricts blood flow to the extremities, resulting in diminished or weak peripheral pulses.

Proper blood circulation relies on healthy arterial condition. When arterial walls become thickened and less compliant, this directly impacts the ability of blood to be effectively pumped through the arteries to the peripheral regions of the body, causing weak or absent pulses. It's important to monitor these changes, as they can be indicative of cardiovascular health and potential ischemic conditions in older adults.
