Clogged arteries are usually caused by high blood pressure and high cholesterol levels. The main role of arteries is to transport oxygen-rich blood from the heart to the rest of the body, and they should be elastic, flexible, and strong.
Yet, if clogged, they lead to serious health risks, including atherosclerosis, the major cause of cardiovascular disease, heart attacks, strokes, and peripheral vascular disease, strokes.
The symptoms depend on their type, as follows:
Carotid arteries: When you have clogged arteries in your brain, it is a condition called carotid artery disease. The plaque will block or narrow the carotid arteries, and signs of a stroke may be present.
Symptoms include breathing problems, sudden weakness, confusion, severe headaches, loss of consciousness, blurry vision, trouble with speech, paralysis, trouble walking, dizziness, unexplained falls, and loss of coordination or balance.
Coronary arteries: Coronary heart disease occurs when the arteries of the heart are clogged, and there is not enough blood to reach the heart. This causes shortness of breath, indigestion, chest pain, and squeezing the chest, jaw, neck, arms, shoulders, or back.
Renal arteries: When the renal arteries are clogged, one develops chronic kidney disease, which reduces the function of the kidneys. In this case, a person does not experience any early symptoms, but as the issue aggravates, symptoms might include fatigue, appetite loss, concentration issues, numbness or itchiness, and swelling in the feet or hands.
