...I have to agree with Barbara. I have generally thought Mr. Perry to be as much a friend as a medical advisor. He is treading a delicate line of wanting to soothe Mr. Woodhouse (which is part of the way he 'treats' his illnesses and/or perceived illnesses when nothing more is called for) yet at the same time allowing leeway for the way he (Mr. Perry) really feels and wishes to conduct his own life. I look at it as a matter of choosing a compassionate method of treating a friend rather than being forced into it. I do know where you are coming from though. I remember my first introduction to Mr. Woodhouse, and I admit I was completely taken aback by him and thought along the same lines as you my first go-round. :) I just happened to read this a couple nights ago by Gill and Gregory:

"The medical aspect of food is associated with Mr. Woodhouse's diet and his concern for his neighbors' consumption: 'What was unwholesome to him, he regarded as unfit for any body'...At his (Mr. Perry's) first mention...it is clear that his function is as much social as medical: his 'frequent visits were one of the comforts of Mr. Woodhouse's life.'"
"He comforts by his tactful acquiescence. When Mr. Woodhouse consults him about wedding cake, Mr. Perry shrewdly discerns the desired answer so declares it 'might certainly disagree with many'. His children were no doubt grateful for such advice as they were to be seen with pieces of wedding cake in their hands!" (lol)

Another source (Janet Todd) says that Mr. Perry's role is that of "a humane and kindly man, whose expertise is as much psychological as physical."

Of course, I respect your desire to continue to feel otherwise. :)
