The breakdown of amino acids and proteins generate toxic ammonia, with is mostly converted into less toxic urea in the
liver and then passed out the body through the kidneys. Therefore, low levels of blood urea or blood urea nitrogen can be caused by a deficit of protein in the diet or due to diseases of the gut leading to poor protein absorption, or protein loss in stools. Diseases of the liver, where urea is made are also important causes. Low urea levels can also be seen in pregnancy and after drinking too much fluid.
Next Steps
Your reports show that the
liver enzymes SGOT and SGPT are high which is a sign of liver damage. A normal serum
creatinine level shows that your
kidney functions are normal. You should talk to a general physician (MD General Medicine) or a gastroenterologist to find out more about the liver parameters that are abnormal.
