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.
Hyponatremia means that the sodium level in the blood is below normal. Your body needs sodium for fluid balance, blood pressure control, as well as the nerves and muscles. The normal blood sodium level is 135 to 145 milliequivalents/liter (mEq/L). Hyponatremia occurs when your blood sodium level goes below 135 mEq/L.yponatremia can be the result of illnesses and medications. Some causes that may be related to kidney disease include: 1  Kidney failure-the kidneys cannot get rid of extra fluid from the body. 2  Congestive heart failure-excess fluid builds up in the body.
