Atherosclerosis is the slow buildup of fatty deposits, called plaque, inside the walls of your arteries. Over time this narrows and stiffens the vessels, reducing blood flow and raising the risk of heart attack, stroke, and other vascular problems.
What is atherosclerosis?
Atherosclerosis is the gradual buildup of fatty material, called plaque, inside the walls of your arteries. The name comes from Greek words meaning gruel and hard, a vivid description of plaque that is soft and porridge-like at its core but stiffens the artery as it grows. Over years, these deposits of cholesterol, fat, and other substances can narrow the channel through which blood flows and make once-flexible vessels rigid.
This process tends to develop quietly over decades, often beginning long before any symptoms appear. As an artery narrows, less blood can pass through, and the tissues that depend on it receive less oxygen. If a piece of plaque ruptures, it can trigger a clot that suddenly blocks the vessel entirely. Depending on where this happens, the result can be a heart attack, a stroke, or reduced circulation to the limbs.
Many of the same factors feed atherosclerosis: high levels of LDL cholesterol, high blood pressure, smoking, diabetes, and a family history of vascular disease. Because the buildup is gradual and silent, it is often detected indirectly, through cholesterol testing, blood pressure readings, or imaging such as a Doppler ultrasound that can show how freely blood is moving. Understanding it as a slow, manageable process rather than a sudden event is part of what makes prevention possible.
Why it matters
Atherosclerosis sits at the root of much of the cardiovascular disease that affects women, including heart attacks and many strokes. Because it builds up silently over years, the choices and check-ups along the way, around cholesterol, blood pressure, and lifestyle, are where much of the influence over future risk actually lies.
Heart disease is sometimes thought of as a man's concern, but it is a leading health threat for women too, and the warning signs can be less obvious. Understanding atherosclerosis as the underlying process behind so many of these events helps explain why numbers like cholesterol and blood pressure matter, and why addressing them early can change the course of your long-term heart and brain health.
