Thank you for sharing this information about Auto-Brewery Syndrome. I looked this up on Wikipedia and 2 of the risk factors are liver cirrhosis and Klebsiella bacteria, both of which my husband had. Although he has now passed away, I am continuing to look for a cause of 2 positive Peth Tests. The second positive Peth test was after he was hospitalized with absolutely no access to alcohol and after a negative Peth test. This should have been a red flag to the doctors that something else was causing it.
