What Causes Plaque Buildup in Arteries?

Plaque in your arteries is a medical condition also referred to as atherosclerosis, which is preventable and treatable. Having plaque in your arteries puts you at a higher risk for diseases including circulatory disorders, heart attack and stroke. According to the Mayo Clinic and the National Library of Medicine, causes of plaque buildup in your arteries include dietary and personal habits.

Blood Pressure

• If your blood pressure is greater than the ideal level of 120/80 mm/Hg, your arteries may develop plaque buildup more quickly than if you had normal blood pressure.

Diabetes

• Type 2 diabetes can cause your arteries to become inflamed, which can make it easier for plaque to stick to the insides of them and build up.

Diet

• If you eat a diet that is high in cholesterol, especially "bad" cholesterol (low-density lipoprotein), excess cholesterol in your blood can cause an increase of plaque in your arteries.

Genetics

• If you have a close family member such as a parent, grandparent or sibling with atherosclerosis, you are more likely to develop this condition as well.

Overweight

• Being overweight, especially if you are also inactive, can cause plaque to build up in your arteries due to a greater volume of blood in your body.

Smoking

• The nicotine you inhale when smoking tobacco can injure your arteries as well as narrow them, allowing plaque to build up and potentially block an artery.
