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.
Excess sodium is excreted by the kidneys via the urine. Sodium levels in the plasma are normally maintained at a level of between 135 to 145 mmol/L. The condition in which plasma level of sodium falls to below 135 mmol/L is called hyponatremia. Hyponatremia causes movement of excess water in the cells, causing them to swell. The cells of the brain in particular are unable to cope up with this swelling since they are confined within the bones of the skull.
