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.
Changes in your body's sodium levels directly affect your body's blood volume (how much water your blood contains). The most common form of sodium imbalance is a blood sodium level that is too high. Excessive blood sodium levels means that your body lacks enough water to cope with the amount of sodium it contains.
