Would you have edema (severe) with euvolemic hyponatremia and would blood work be normal?

Urine electrolytes. Euvolemia means there is no evidence of dehydration nor fluid overload. Typically there is no edema in euvolemia. Hyponatremia - low serum sodium levels. One should check urine electrolytes to find out the exact reason for low serum sodium. This problem usually needs nephrologist consult.
