Sucralose (Splenda) & Liver Issues

just because you eat low fat doesn't mean you don't have fatty liver disease.  Increase liver enzymes could mean many different thinks.  I wouldn't worry about it to much.  I have had increase liver enzymes for more than 20 years.  The best thing you can do for it is lose weight.  Which you did.  It could just be a reaction to having your gallbladder remove.  It sounds like you are in good hands with your doctors. 

Artificial sweetners can be really bad for some and other can tolerate the sweetners.   It can cause multiple health problems.  I would try to cut down as much as possible.  I use stevia and coconut sugar for a sweetner.

Hope you get better soon.
