Low blood sodium is a condition in which the body has imbalanced water and sodium levels, explains Healthline. Sodium is an essential electrolyte that helps maintain adequate amounts of water in and around the cells, and contributes to the proper functioning of the muscles and nerves. Excessive loss of water and electrolytes typically leads to low sodium levels. Intense vomiting, severe diarrhea, pain medications, antidepressants and diuretics are also possible causes of low sodium. Other causes include dehydration, kidney disease, liver disease, heart conditions and adrenal gland disorders.

Anyone who loses sodium quickly requires immediate medical care, as the condition can lead to seizures, unconsciousness or coma, notes Healthline. However, people whose sodium levels decrease slowly usually do not experience symptoms. Typical symptoms of low blood sodium include muscle cramps, nausea, vomiting, headache and fatigue.

To prevent low blood sodium, a person should drink more fluids during warm days, at high altitudes, during rigorous exercises, when having a fever, or when pregnant or breastfeeding, recommends Healthline. Athletes should drink less than 1 liter of fluids per hour.
