Without invasive surgical procedures like angioplasty, stent replacement, and bypass surgery, it is very difficult to unclog arteries. The best clogged arteries treatment is the prevention of plaque build-up. Medication and lifestyle changes can help prevent plaque formation and ease symptoms.

Plaque formation and inflammation are usually the main causes of blocked arteries. Plaque is a sticky residue made up of calcium, cholesterol, and fat deposits, which can build up on the walls of the arteries. This constricts the blood vessels, causing reduced blood flow to the heart.

Some symptoms of clogged arteries include:
Chest pain (angina)—Pressure or tightness in the left side of the chest is a common symptom of clogged arteries
Shortness of breath—When the body cannot pump enough blood to the rest of the body, it may result in shortness of breath
Heart attack—A fully blocked coronary artery results in a heart attack. Signs and symptoms of a heart attack include dizziness, fatigue, pain in the chest, pain in the arms, neck, jaw, or shoulder, shortness of breath, sweating, and nausea.

There are no specific supplements that can unclog arteries, only surgery can clear a blockage. However, omega-3 and flaxseed can help improve heart health.

Vitamin D in excessive quantities in the body can cause arterial stiffness. However, most people are deficient in vitamin D, hence it is not advisable to avoid this important nutrient altogether. Instead, stay within the daily recommended dietary allowance.
