Heart disease has become more common over the last few decades. With unhealthy eating habits and a predominantly sedentary lifestyle, there is extreme pressure on this vital organ. While heart disease may not always have noticeable symptoms, there are several early warning signs to watch out for. Learning about them can help individuals recognize them early, giving them a better chance at averting the risk by making lifestyle changes and seeking timely professional help. Here are a few early signs to look out for: 1. Chest pain Chest pain is one of the most common warning signs of an underlying heart condition. It generally happens because of poor blood flow when the heart does not receive enough blood or oxygen. This is referred to as angina, and it may cause pain that feels different for everyone. Some may experience debilitating pain, while others may only feel a slight discomfort. 2. Pain that spreads to the arm Pain that begins in the chest and spreads to the left side of the body, especially the arm, is noted to be a classic sign of a heart attack. 3. Shortness of breath A weakened heart cannot pump blood effectively into the body. This causes the blood to back up in the veins, which can be fatal.
