Diagnosis and Management of Sodium Disorders: Hyponatremia and Hypernatremia.
Hyponatremia and hypernatremia are electrolyte disorders that can be associated with poor outcomes. Hyponatremia is considered mild when the sodium concentration is 130 to 134 mEq per L, moderate when 125 to 129 mEq per L, and severe when less than 125 mEq per L. Mild symptoms include nausea, vomiting, weakness, headache, and mild neurocognitive deficits. ⋯ Mild hypernatremia is often caused by dehydration resulting from an impaired thirst mechanism or lack of access to water; however, other causes, such as diabetes insipidus, are possible. Treatment starts with addressing the underlying etiology and correcting the fluid deficit. When sodium is severely elevated, patients are symptomatic, or intravenous fluids are required, hypotonic fluid replacement is necessary.

Family physicians commonly find themselves in difficult patient encounters that can result in dissatisfaction for the patient and physician. Successful navigation of these encounters includes recognizing common physician factors, such as systemic pressures, interpersonal communication, and situational issues. The practice of labeling patient types can lead to disparities in care and patient harm and should be avoided. ⋯ Supporting patients by validating their symptoms and helping them embrace uncertainty can enable them to take control of their diagnosis and focus on managing chronic conditions rather than curing them. Motivational interviewing is a useful tool to help patients take ownership of their illnesses and therapeutic goals. Self-care through reflection groups or personal coaching or counseling can help physicians feel supported and avoid burnout.
