Brief Answer:

Various causes

Detailed Answer:

Hello,

Increased sodium excretion in urine beyond normal levels could be due to a number of causes such as adrenal insufficiency and low cortisol levels, syndrome of inappropriate antidiuretic hormone secretion, salt-losing nephropathy, and thyroid hormonal imbalance.

So I would recommend that he gets a blood test of the cortisol level, the antidiuretic hormone level and a thyroid hormonal profile including T3, T4, and TSH to exclude or confirm any of these causes.

Treatment is initiated once a diagnosis of the cause has been established.

Hope I have answered your query.

Take care
