     Doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients

about it?

     The results of two surveys, one of primary care physicians and the other of patients, found that while

most doctors want to help patients lose weight and think it is their responsibility to do so, they often don't

know what to say.

      So while doctors may tell patients they are overweight, the conversation often ends there, said

Christine C. Ferguson, director of the Stop_Obesity_Alliance. Without being told about options for

diabetes, she said, "Doctors don't feel they have good information to give. They felt they didn't have

adequate tools to address this problem."

     The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most

overweight patients don't even know that they' re too heavy. Only 39 percent of overweight people

surveyed had ever been told by a health care provider that they were overweight.

     Of those who were told they were obese,90 percent were also told by their doctors to lose weight,

the survey found. In fact most have tried to lose weight and may have been successful in the past-and

many are still trying, the survey found. And many understand that losing even a small amount of weight

can have a positive impact on their health and reduce their risk of obesityrelated diseases like

hypertension and diabetes.

     Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn. , which

ranks the 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an

ongoing one and could not be dropped after just one mention of the problem. "If you're to be successful

with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them, " he said.

     He acknowledged that many doctors tend to be not optimistic.

"Part of this is that there's this common belief, and doctors are burdened by it, too, that overweight

people are weakwilled and just don't have any willpower and are selfindulgent and all that business, "he

said. "If you think that way, you're not going to spend time having a productive conversation."
