Water and salts (sodium, potassium, calcium, etc.) form a delicate balance in the body. In this condition, the balance is disrupted by kidney injury, hormonal disturbances, and other causes.
Your doctor may ask these questions to check for this disease:
The goal of treatment is to restore electrolytes to normal levels. Mild imbalances can be managed through dietary changes and electrolyte supplements. In severe cases, salt-containing fluids may be given by a needle in the vein.
