It turns out that there are several instances where she chooses her doctor's advice above the Church's. For example, this doctor advises large quantities of meat to be ingested at every meal, which contradicts the Word of Wisdom as written in the Doctrine and Covenants of the Church. Additionally, several of the herbal mixtures the doctor prescribes contain alcohol, which, according to the Word of Wisdom, is "not for the belly."
I think similar questions could be asked to several of the members of the Church. I know of no one who follows LDS guidance to the absolute letter of the law, and I would love to know why this discrepancy exists. When given a choice to follow "the prophets" or someone else, why is it that so many members make decisions that go against what "the prophets" have said?
For example, I know very active members who buy lottery tickets regularly. I know dozens who watch rated "R" movies. I know several who get tattoos or extra piercings despite statements against these by The Brethren. My experience is that only about half of home teaching gets done in any given month. I know a gentleman now who is very active and insists he knows the Church is true, but has chosen to work on Sundays despite promises of great blessings for keeping the Sabbath day holy (example). Without words, he has said that he either doesn't want those blessings, or that he truly does not believe that is a true promise.
I don't mean to call these individuals hypocrites, because that is a bit too far past my point. What I want to point out is that it seems faithfulness is a continuum. Even the most faithful of LDS have instances where somewhere deep down they tell themselves "Oh, that doesn't apply to me. I'm sure God will make an exception. That's more of a guideline than a commandment, even if the prophet said it. It's not that bad."
And what does this tell us about a testimony "beyond a shadow of a doubt"? If these people did have absolute faith in their testimonies, why are they telling the world, "I know that Thomas Monson is a prophet of God, but I won't do my home teaching like he asks," or "I follow the Word of Wisdom, except for this part and this part."?
Doesn't it really mean that everybody follows the Church up to the point where they actually disagree with its absolute truthfulness? Sure, we are all imperfect and working on our weaknesses, but when someone consciously chooses against the Church, but insists that it is the absolute truth in the universe, how am I to interpret just how convinced that person really is? Are they trying to convince me, or themselves?
