Hello and thank you for posting your medical question on E health forum. â
ALT (also called alanine aminotransferase or SGPT) is found in the liver only. The normal range âof ALT levels is between 5 IU/L to 60 IU/L High levels of ALT (1600 IU/L) is an indication of âliver inflammation and/or damage. â
In your case, the severe elevation of both the bilirubin and enzymes is more likely due to hepatitis associated with either viral infections (Hepatitis A, Hepatitis B or C).
Hence you might consult with a doctor, who can examine you and order for hepatitis serology panel, and a ultrasound which will help to make a proper diagnosis.
In case your symptoms are mild (as mentioned), out patient treatment may be sufficient. Only in case of severe symptoms and inability to have food, will hospitalisation be necessary.
I hope this helps to clear your doubts.
