Summary

This study is examining how a dietary supplement called urea can be used to treat low blood sodium level. Low blood sodium level is a common problem and some studies show that many patients with low blood sodium level suffer from brain fog and/or loss of balance. Unfortunately, it is unknown at this point what the best treatment is for low blood sodium level. With this pilot research study, the investigators are hoping to learn more about whether urea is safe to take, whether patients can tolerate taking urea for several weeks, whether urea increases blood sodium level, and whether urea can help prevent the brain fog and/or loss of balance that some patients with low blood sodium level suffer from. The information obtained with this study is intended to be used to design a larger study in the future to get a definite answer whether urea is beneficial for patients with low blood sodium level.

Urea

Groups "On Urea, Then Off Urea" and "Off Urea, Then On Urea" will receive urea during period 1 and period 2 of the study, respectively. The investigators will use the new American formulation of oral urea (i.e., Ure-Na™), which is packaged as a powder and mixed with 4 ounces. of water for oral consumption. Urea will be started at a dose of 15 grams of urea per mouth once daily. Dose titration will be based on the absolute increase in PNa on days 7 and 14. The urea dosing scheme will involve increasing from the starting dose of 15 grams/day to 30 grams/day (in 2 divided doses) based on the change in and absolute value of PNa, and subsequently, from 30 grams/day to 60 grams/day (in 2 divided doses) when indicated. The maximal dose of urea administered will be 60 g/day.
