Well, I had a long consultation with my regular GP today, and he talked me through the results of the liver function tests, complete blood count and clotting tests that I had on Tuesday of this week. I couldn't get a copy of everything - there was too much - but here are some important ones:
Serum Albumin: 48 g/l (normal range: 35-50);
Serum total Bilirubin: 7 umol/l (0-21);
Serum gamma GT: 70 U/L (0-61 - it had been as high as 121 in August);
AST serum level: 23 U/L (0-40 - had been as high as 96 in August);
Alk Phos: 84 U/L (30-130);
Platelets: 390 (150-450);
Prothrombin Time: 9.3 (9.0-12.0).
Unfortunately, there is no AST value. The doctor said that is not done routinely, and I have never had it checked for either by the doctor's surgery or hospital.
Everything else in the various blood tests was in normal ranges.
The docor said that the AST quickly coming back down to normal and the GGT returning to near normal (he said it takes longer to do so after a spell of heavy drinking) and the other normal, healthy test results show that I definitely do not have cirrhosis or any form of permanent liver damage or advanced liver disease, and that the fatty liver will resolve itself with continued avoidance of heavy drinking.
I'm sure he thought I was crazy, saying things like I was worried that an already damaged liver would not show raised enzymes because it was not functioning and would not be producing them, but he said that, if that was the case, there would be many other abnormalities in the tests, whereas everything else was normal, and I would also be displaying very severe symptoms, other than just tiredness.
I asked him about my minor hair loss and more general thinning and poor condition of hair. He said it was not liver related, but may be hormonal. He raised the idea of checking my thyroid function (my mother and sister both have thyroid issues), but then we started talking about something else and forgot about that. I think a thyroid problem might explain some of the symptoms I've been displaying - tiredness, weight loss, hair problems, excessive sweating - and, if there is a problem with it, it's easily fixed. I'm not worried about that, but, if it is not functioning properly and is put-right, I might feel physically better. So, I'll see how I feel for a few days and think about going back to get it checked.
So, as far as the liver is concerned, I guess I am still worried because it showed-up fatty on the ultrasound, I'm kicking-myself about the excessive drinking, and stil don't feel physically great, but guess I should feel somewhat reassured and just try to continue to live more healthily than I have been doing for most of the past year.
