Nausea
This is a sickening sensation which includes an urge to throw up. Nausea is also one of the signs related to heart disease. Now you see the reason a heart disease can be tricky because at times you do not get to know that the symptoms you are feeling have to do with the health condition of your heart. Of course, nausea can have causes that are not due to underlying diseases, such as excess consumption of alcohol, motion from a car or plane, excess consumption of food, etc. But to be on a safer side, get to know the cause of your nausea.
