Heart failure occurs when the heart is not able to pump as well as it should; it doesn’t mean the heart stops working, it only translates to the heart not working as efficiently as it should for a person to have a normal and healthy life. (Source) Congestive heart failure (CHF), commonly referred to as heart failure is a stage where fluids accumulate around the heart, making it difficult for the heart to pump well. The heart is made up of ventricles and atria; the ventricles pump blood while the aorta receives blood back from the body. When Congestive Heart Failure sets in, however, the ventricles will not be able to pump enough blood, and this can cause a number of symptoms. It is imperative that any heart condition is diagnosed early while it might still be treatable. Some symptoms of CHF are discussed below, and if you begin to notice any of these, visit your doctor immediately, so that a proper diagnosis can be carried out.
Several things can cause you to feel dizzy and lightheaded all of a sudden. If you haven’t had enough food to eat or enough water to drink, you might feel dizzy.

If you ever develop sudden dizziness, or you develop shortness of breath and feel you can’t explain the cause, you should see a doctor. (Source)
