Which symptom is commonly associated with fluid overload in dialysis patients?

Fluid overload in dialysis patients often manifests through symptoms such as shortness of breath (SOB) and edema. When a patient experiences fluid overload, their body retains an excessive amount of fluid, which can lead to swelling in various parts of the body, particularly in the lower extremities and in the lungs. The accumulation of fluid in the lungs is what causes shortness of breath, making it difficult for the patient to breathe comfortably. This can be particularly problematic for individuals who are on dialysis since they have renal dysfunction that limits their ability to excrete excess fluid.

The other symptoms listed do not align with fluid overload. Dry skin typically indicates dehydration rather than fluid accumulation. Rapid weight loss would suggest that the patient is losing fluid rather than retaining it. Increased urine output is associated with good kidney function or recovery from dehydration, while dialysis patients may experience very limited urine output or none at all, depending on their stage of kidney disease. Thus, the presence of both shortness of breath and edema is a clear sign pointing toward fluid overload in this context.
