2. Nausea
When a person is feeling emotional or physical stress, it is common to feel sick to our stomachs. In fact, if you become extremely stressed you may even actually vomit. Nausea is often a sign of the body being under some type of trauma. However, it can also be caused by something milder.
Since an issue with the heart can be a considerable trauma, it is no real surprise that nausea can be a symptom when something is wrong with the heart. Women are more likely to report being nauseous or having an upset stomach when they suffer from congestive heart failure or a heart attack.
Of course, an upset stomach can occur for numerous reasons that do not have anything to do with the heart. However, it is important to note that it is a symptom of heart failure or a heart attack, so if you are experiencing an upset stomach along with other symptoms, go to your doctor right away.
