Hypervolemia, or fluid overload, is the medical condition where there is too much fluid in the blood.

The opposite condition is hypovolemia, which is too little fluid volume in the blood.

Causes

Excessive sodium or fluid intake:

Sodium or water retention:

Fluid shift into the intravascular space:

Symptoms

The excess fluid, primarily salt and water, builds up in various locations in the body and leads to an increase in weight, swelling in the legs and arms (peripheral edema), and / or fluid in the abdomen (ascites). Eventually, the fluid enters the air spaces in the lungs, reduces the amount of oxygen that can enter the blood, and causes shortness of breath (dyspnea). Fluid can also collect in the lungs when lying down at night, possibly making nighttime breathing and sleeping difficult (paroxysmal nocturnal dyspnea).

Complications

Congestive heart failure is the most common result of fluid overload. Also, it may cause hyponatremia (hypervolemic hyponatremia).[3]
