The heart has to work every second to ensure that oxygen and blood reach every part of the body. A blockage in the blood supply to the arteries can be life-threatening. In medical terms, this is called coronary artery disease or heart blockage.

However, this condition doesn't happen suddenly, and the body gives several warning signs before it occurs. In this article, we will learn what those signs are and how to identify them to avoid this life-threatening situation.

Chest Pain
This is the most common symptom of heart blockage. If you feel pressure, burning, or tightness in your chest, these could be signs of angina. This usually occurs during stressful situations or strenuous activities. However, it often subsides with rest.

Difficulty Breathing
If you experience shortness of breath even after minimal exertion or climbing stairs, it indicates that your heart is not receiving enough blood. This can be an early symptom of heart blockage. It is essential to seek medical advice immediately if this happens.

Fatigue
If you feel tired even after performing small, everyday tasks, it means your heart is not supplying the body with the right amount of oxygen. This can also be a major sign of heart blockage.

Pain in the Arm, Neck, or Jaw
Sometimes, heart problems are not felt in the chest but in other parts of the body, such as the left arm, back, or jaw. Often, people ignore this pain, mistaking it for muscle pain, but it can also be a sign of heart blockage.

Irregular Heartbeat
If your heart rate suddenly increases or fluctuates, or if you feel dizzy or lightheaded, these could be signs of a blockage.

Possible Causes of Blockage
High cholesterol levels
High blood pressure
Smoking
Diabetes
Sedentary lifestyle (working for long periods in one place)
Family history of heart disease
