This is my first post here. I'm 27 years old, and for about four years now, I have been having intermittent pain in my right upper abdominal quadrant. Sometimes this pain is kind of a vague and dull ache, other times it is a bit sharper and more localized. It is always on the right side under the ribs.
During this time, I have had LFTs (including AST, ALT, ALP, albumin, bilirubin, and globulin) drawn on probably six separate occasions, and never have any of these results been abnormal, save for when I had mononucleosis in 2013, which I was told was to be expected. I had an ultrasound done in '13 which showed "mild fatty infiltration" and a liver span of 14.7 inches. I had another sonogram done in September of '16 which reported that the liver was "homogenous in architecture without focal abnormalities. Prominent, measuring 18 cm."
My gastroenterologist says that although this 18 cm measurement falls slightly outside of what is typically considered the normal range, it is nothing to be concerned about because the report does not talk about any fatty infiltration or remark on any other findings that would suggest liver damage, and especially since my enzymes have never been outside the normal range.
My most recent LFT numbers, collected 11/30/16, were:
Bilirubin total: 0.7
I continue to have the upper right quadrant discomfort, though, especially after I drink alcohol. I am probably a heavier drinker than most -- it's not uncommon for me to have 3-4 beers on a weeknight and anywhere between 6-10 on a weekend. I am cutting down -- in fact I went six weeks without any alcohol at all in September/October -- and that does seem to help with the discomfort somewhat, though not entirely.
My gastroenterologist thinks the symptoms are more likely due to trapped gas in the hepatic flexure of the large intestine or intestinal spasm rather than an issue with the liver. My question is, can a liver of 18 cm really be a normal variant, especially since it was significantly smaller in the last sonogram? Has anyone else experienced a similar situation?
I know I should probably be satisfied with the results and move on, but I just can't shake the idea that something is wrong with my liver.
Any feedback or sharing of relevant experiences would be appreciated. And full disclosure, I'm American, not a Brit, though I did study in York for six months in college.
