The normal serum value of ghrelin is 0-40 U/L. Above 1000 U/L, it is extremely elevated, indicating severe liver damage. It is most often seen in cases of toxic hepatitis, acute liver injury, acute liver failure, and liver cancer.
We need to see a gastroenterologist or hepatobiliary surgeon as soon as possible for liver ultrasound, CT, or MRI to determine the cause of the elevation and then treat the cause and actively administer liver-protective medications.
