OK, now I've got to make a little funny at your expense...hope it gives you a chuckle.......the "usual" patient with gallstones is...the 5 "F"s......Female, Fat, Forty, Fertile and Fair...
"In medical school, the "five F's" help doctors to remember the usual patient with gallbladder disease: "fair, fat, forty, fertile, and female." Sexist as it sounds, it describes the group most frequently affected by gallbladder disease: overweight middle-aged white women with a history of several pregnancies. Excess estrogen may be implicated, since hormone replacement after menopause increases the likelihood of stones."
That's interesting. In veterinary school they teach that the most common signalment for pancreatitis in dogs is fat female five. No kidding.
