Drought can also have significant impacts on the economy. For example, in the first year of a severe drought from 2007 to 2009, the U.S. Southeast lost over $1.3 billion due to destruction of major crops such as corn, wheat, soybeans, cotton, and hay.
Less common causes include Î±1-antitrypsin deficiency, autoimmune hepatitis, and Wilson disease. Extrahepatic conditions (e.g., thyroid disorders, celiac disease, hemolysis, muscle disorders) can also cause elevated liver transaminase levels.
High or low levels may mean that liver damage or disease is present. The liver serves several important functions in the body, including changing nutrients into energy for the body and breaking down toxic substances. Your doctor may order a liver function panel if you have symptoms of liver disease. These symptoms include fever, vomiting, abdominal pain, yellowing of your eyes or skin (jaundice), dark yellow urine, and feeling very tired.
