I'm a GP...almost every abdominal scan I request for anyone over middle age shows fatty liver....even if the scan was for a non liver related reason.
This is in thin as well as fat people.
Personally, I had a scan for possible gallstones more than 20 years ago.
No stones but, yes , fatty liver!
I am now almost 70 . Slightly over weight but attend Weight Watchers. I like a glass of wine and my own liver function tests last week were perfect.
Most people's are.
For those whose liver tests are a bit off we do do the aforementioned Fibroscan.
This isto assess for liver stiffness and try to predict whether a patient might progress to cirrhosis.
Most are satisfactory, even in heavy drinkers.
I think your predilection for developing liver disease may be either genetic or just random bad luck.
Sometimes people get advanced disease and are very moderate drinkers.
Hopefully I can encourage you that fatty liver is common and very few advance to cirrhosis.
There's a but though.....don't over indulge in anything and, if your tests do show rising levels of liver damage then, take action!!
Do not ignore.
Liver failure is a truly horrible way to go....and, apart from the unfortunate few who have one of the rare liver conditions, you are responsible for the health of your liver and you can, and should, do something about it .
