Hypervolemia or fluid overload is a condition in which there is too much fluid in the blood. This can throw off the body’s chemical balance, increasing sodium levels. Hypervolemia often resolves on its own, but it is usually a sign of an underlying health issue. Some of the most common symptoms of hypervolemia include unexplained or rapid weight gain, shortness of breath, or swelling in the abdomen, arms, hands, ankles, and legs. A person with hypervolemia may have an irritated cough, distended jugular vein, or rapid pulse. There are many causes of hypervolemia.

1. Congestive Heart Failure

Congestive heart failure occurs when the heart muscles lose their full pumping power. In this state, the heart cannot pump enough blood to make the body function at its best. Ultimately, the other organs may begin to malfunction. For example, the kidneys stop working as they should and create excess fluid. Hypervolemia is common in people who have chronic heart failure. It also never goes away completely, even if doctors are treating it.
