Dear Mother, yes I agree, it sounds like liver congestion. I have some of the same symptoms after having my GB out. There is a definite increase in anxiety which is highly correlated with lack of proper liver flow. I actually thing that taking the GB out exacerbates liver congestion - translation, liver stones instead of gallbladder stones. I have them!
what to do: Liver Flush olive oil/lemon juice
Beet/apple juice - you would be surprised how well this works
Milk Thistle supplement - increases bile flow
Golden Seal - increases bile flow
Exercise - raises HDL, increases bile flow
Hydration - thins bile
Sam E - increases Glutathione a natural antioxidant that helps flush liver toxicants
Fish oil - increases HDL, thins cholesterol
Diet - carful w/ the bad foods, carbs, sugar, trans fats... need I say more about that?
If she does even some of these things it will help, I do each at different times and it seems to keep my motor running, though not a perfect machine like before.
There is a connection between liver congestion and heart attacks, she should start working the problem right away.
