You may need to say your question in another
way since it appears that you are asking if it
is possible to have a liver/gallbladder and most
people have gallbladders unless it was removed,
and everyone has a liver since it is not possible
to survive without one.
Most people would benefit from liver flushing
as a part of good body maintenance. Once you
flush your gallbladder/liver and are stone free,
you can maintain that by using good plant oils
in your diet, especially supplementing with
lecithin would be beneficial. If you have pale
stools, you are not producing enough bile.
