If
a prescription gave you diarrhea or made you vomit, you would complain. But
until well into the twentieth century, people looked on a good “purge” as an
excellent way to expel toxins. Physicians took pride in their cathartics, and
when patients discussed a doctor’s skill, they gave high marks for the violence
of his purges.
People
who consult a doctor expect him to behave in certain ways. 21st
century Americans frown upon purges, but this is not a mark of superiority
because we seem to expect medicine. It should be one only a doctor can
prescribe; over-the-counter drugs don’t count. Pills are good; an injection
works better.
Most of you will deny expecting medicine whenever you
see a doctor. You want help. If you’ll get well without medicine, you won’t be
upset… I often encounter such patients, but the other sort turns up regularly.
I’m slower to prescribe than most, so I have many opportunities to see
disappointment in patients’ eyes when they realize I don’t plan to “give them
something.” This makes me feel bad.
Doctors genuinely want to help you, and it depresses us
when we can’t. We also feel bad when we’ve done our best, and you don’t feel
“helped.” So we often add a prescription or order a test to convince you that
we’re doing what a proper doctor should do.
