5. Nausea and Lack of Appetite
When heart disease progresses, it creates a build-up of fluid around major organs including the liver and intestines. These are directly related to the digestive functions of the human body. So, if they are not able to work properly due to fluid build up around them, the result will be feeling nauseous when you are eating or directly afterward, or even an inability to keep food down leading to pain in the stomach region. It can also result in not having an appetite at all even if you have not eaten for hours and even days.
