Symptoms depend on many things, including: 1  Type and strength of voltage. 2  How long you were in contact with the electricity. 3  How the electricity moved through your body. 4  Your overall health.
Hyponatremia refers to a lower-than-normal level of sodium in the blood. Sodium is essential for many body functions including the maintenance of fluid balance, regulation of blood pressure, and normal function of the nervous system.
Low sodium levels are uncommon and are most often caused by heart failure, malnutrition, and diarrhea. Other electrolytes, such as potassium, calcium, chloride, magnesium, and phosphate, may be checked in a blood sample at the same time as a blood test for sodium.
