Cystic disease of the liver is rare and can take several forms. Cysts in the main trunk of the biliary tree are called choledochal cysts. Cysts that occur in the small branches of bile ducts within the liver are referred to as Caroliâs syndrome.
Low sodium levels in the blood occur when there is a lower than normal concentration of sodium in the blood. This is a condition often referred to as hyponatremia. Sodium is an electrolyte that helps maintain blood pressure and helps regulate nerve and muscle function. Low sodium levels can cause symptoms including confusion, lethargy, and cramping, which are usually brought on by other medical conditions or illnesses. Low sodium levels in the blood can occur due to a number of causes and conditions that can be detected.
The body needs sodium to help keep fluids in balance. After you consume sodium, the body processes it through the kidneys and sends excess out of the body in sweat and urine. Low sodium levels can occur when there is not enough sodium in the blood compared to the amount of fluid, so sodium dilution occurs. Normal blood levels for sodium range between 135 and 145 milliequivalents per liter, according to the University of Maryland Medical Center.
