Clogged arteries can be dangerous. If you have clogged arteries, you may experience pain in your limbs or poor circulation. Clogged arteries can lead to conditions like heart attacks, heart disease, peripheral artery disease and stroke. Even though they're best known for negatively affecting the health of your heart, clogged arteries can occur anywhere in your body. Clogged arteries are thought to be caused by various factors, including high blood pressure, blood sugar and cholesterol. Certain foods can increase your blood pressure, blood sugar and cholesterol and consequently also lead to clogged arteries. Other factors, like whether you exercise and smoke, can also increase your likelihood of having clogged arteries.
