Heart disease is the most common cause of death among Americans, according to the American Medical Association. One reason is that many people with heart disease never seek treatment for their condition, allowing the problem to get worse and worse. There are six major symptoms you should watch out for. If you experience any of these problems, go see a doctor as soon as possible.


1. Fatigue


Everybody gets tired sometimes, but sustained, severe fatigue can be a sign of heart disease or even an impending heart attack. If carrying a bag of groceries or strolling in the park leaves you feeling beat, it could be due to your heart’s inability to pump fresh blood to your muscles. 


2. Shortness of Breath


If climbing a few flights of stairs leaves you gasping for air, it could be a sign of a heart problem. Heart disease reduces your ability to supply your muscles with oxygen, making it difficult to sustain physical activity over a long period of time. It’s perfectly normal to feel winded after jogging a few miles, but if you run out of air after a walk down the street you should call your doctor.
