An unmanaged sodium level may result in dehydration. A sodium level greater than 140-150 mEq/1 indicates dehydration.  If it gets no higher than 155 mEq/1, the dehydration is relatively mild and is unlikely to cause a severe problem but it could and probably would produce slight brain damage that could gradually increase over long periods of time.  Therefore, an effort should be made to keep the sodium below 150 mEq/1.
