### input:
I am a 25 year old male Caucasian. I had an ultrasound about 7 days ago to check on gallstones which were originally found 4 or 5 years ago. The ultrasound showed Cholelithiasis is demonstrated , Incidental adenomyomatosis of the gallbladder . and Borderline hepatomegaly . . The report also says The liver is at the upper limit of normal for size, right lobe measuring 15.5cm. The liver is smooth in outline and homogenous in echotexture with a normal echo pattern. No focal hepatic mass. No splenomegaly . No ascites . . Also, my liver enzymes WERE elevated around 4 Oct 2012 (AST 40 U/L, ALT 77 U/L and GGT 72 U/L) and on 3 Dec 2012 mostly back in normal range except for GGT (AST 25 U/L, ALT 35 U/L, GGT 65 U/L). I do not drink and have only had a total of two or three standard drinks in total during my lifetime. Recent STD check showed no Hepatitis STDs. Additional possibly useful info: I weighed 85 to 87 kg around March 2012 (note I was not muscular by any means), between May and July I got my weight down (intentionally with a low calorie and low/almost zero carb diet) to 68kg and have been around 68 to 70 kg since that time. I am worried about my liver. What could be wrong, if anything? What follow up tests should I now get done? My G.P. seemed uninterested and more concerned about seeing more patients he can bill.

Hello! Thank you for the query. If a patient in young age (like yours) has a gallstone, surgery needs to be done. It's because sooner or later, gallstones will start to giving you the pain and can lead to acute pancreatitis.However, your liver condition is not caused by gallstones. It's rather your diet has caused both, liver problems and gallstones. And as you can see, when you improve your diet, your liver tests get back to normal. This is a very good way to help to the liver and keep it healthy. Please avoid fatty foods, fried foods, spicy foods, alcohol and painkillers. Increase vegetables, whole grains and mineral water intake and your liver will be fine. No need to worry about it. You should also have your gallbladder removed. Hope this will help. Regards.
