Increased bilirubin could be from Lyme and/or coinfections (Bartonella, Ehrlichia/Anaplasma, that I know of...), or something else entirely. When MD's blow off abnormal lab results, that's when I start wondering what the point of having a "normal range" on a lab report is - why bother, if the doc's just going to ignore it! If it comes back higher next time you have labs, I would push for more info instead of tolerating another "blow job" by the doctor.
Livers are amazingly tolerant of all the abuse we give them (pollution, chemical food additives, imbalanced diets, infection/die-off, etc.), so when abnormal test values on a lab report start showing up, that means the liver has been struggling for a while and it is usually a good thing to pay attention to, even if the increase is small.
What to do at this point? Detox, detox, detox! It is the only way I know of to help the liver. Even if it's from a coinfection? Yes! The reason these infections elevate liver lab values is because of the buildup of gunk in the liver. Helping the liver to detox (through bile secretion) is the only way I know of to get rid of the gunk. Milk thistle (silymarin is the active ingredient), glutathione, detox baths, skin brushing, drinking more water, etc. are all good ways to help take the load off the liver and give it some breathing room so it can repair itself and get back to normal on those lab reports.
There is some excellent detox info in the newbies thread at the top of the forum...
