Indirectly, yes. Having her gallbladder removed means she must have a lot of intrahepatic stones in the liver, which affects digestion, kidney, liver, blood, circulation and lymphatic functions. The liver is unable to remove all the toxins from the blood, which subsequently congests the "filters" of the kidneys. This can raise blood pressure considerable. In additon, due to the missing gallbladder, protein-rich foods become virtually undigestible (they need fat to digest them, but without being able to digest and emulsify fats, the proteins are rendered useless also). The undigested proteins then clog up blood vessel walls in thekidneys and elsewhere in the body, which is another cause of high blood pressure. Liver flushing and change of diet are essential here to get restore normal blood pressure.
