Fluid overload occurs when the body retains more fluid than it can effectively manage. This condition can lead to swelling, high blood pressure, and strain on the heart. It is often seen in individuals with heart failure, kidney disease, or those receiving excessive intravenous fluids. Symptoms of fluid overload may include shortness of breath, rapid weight gain, and swelling in the legs or abdomen. Treatment typically involves reducing fluid intake, using diuretics to help the body eliminate excess fluid, and addressing the underlying cause, such as managing heart conditions or kidney function.
