Doctors refer patients with diabetes and blood glucose disorders to nutritionists for meal planning. Some doctors also refer patients to diabetic teaching courses, which provide education to patients in an attempt to regulate blood sugars, according to ExploreHealthCareers.org. Dietitians and nutritionists are often found at locations outside doctors' offices.
Most doctors do not have nutritionists on staff, although physicians' offices dedicated to treating only diabetic patients may have a dietitian on staff, reports ExploreHealthCareers.org. Clinics are available that focus solely on blood glucose level stabilization through meal planning and food knowledge teaching. Nutritionists teach diabetics how to portion their food, what foods to avoid and how to have a sinful treat without their blood glucose levels getting out of control.
