That's the thing you don't drink which "REELLY" reduces your risk to liver damage. The thing is that alot of people on medication also drink which is a double whammy when it comes to a damaged liver. But there have been cases where a blood tests were done on an individual and all his liver enzymes were in the normal range, which gave them a false feeling that everything was okay with their liver and then all of a sudden they develop liver conditions like cirrhosis or fatty liver and were taken by surprise. Liver enzymes tests only reflect and provide a snapshot on how the liver is functioning. But the liver can withstand alot of damage before actual liver damage signs show-up. And liver function is only one side of the story, the other side of liver function is that the liver must be addressed at it's structural level (histologically) at the cellular level. The structure must be viewed and analyzed by a competent hepatologist and the doctor should take a close look at an individual's health for any hidden or sub-clinical symptoms that might point to liver damage. God has bless humans with providing us with an organ that has excellent regenerative abilities. It's when you destory the liver beyond the body's ability to regenerate it, and the body instead replaces the damaged portion of the liver with scar tissue, which is just connective tissue, it contains none of the specialized cells that are present within liver tissue (similiar to a scar seen on external skin it's there but it contains no hair follicles or sweat glands...etc within in, it's sole purpose is to connect all sides of healthy skin to one another and nothing else). So now the liver loses the ability to neutralize and remove harmful substances from the blood and the digestive contents of the small intestine and now the person is in big trouble and needs a liver transplant pronto. There no need to get stressed about it, just make sure you take the milk thistle, NAC, green tea, dandelions, and schisandra fruit (tea bags) on a daily basis to promote healty liver function. And if you have take painkillers that contain tylenol, ask the doctor to write scripts with the least amount of tylenol like norco 10mg hydrocodone/325mg tylenol, or oxycodone 10mg with 325 mg tylenol. Even if you don't need that high of a dose. you can always break the pill in half, they are scored. Just always remember to monitor your tylenol intake and absolutely abstain from alcohol. Kewl!!!
