Characteristics of Refeeding
Syndrome
 Increases BMR
 May lead to confusion, coma, convulsions
and death.
 Caused by introducing food to quickly to a
malnourished person.
 Prevent refeeding syndrome by slowly
introducing foods in small amounts and
advancing as tolerated.
Questions regarding Paris’ purging
behaviors
1. What types of food trigger your bingeing/purging
episodes?
2. What food rituals do you have?
3. What foods do you consider fear foods?
4. What other behavior could you do when you feel a
bingeing/purging episode about to occur?
5. What weight would you consider healthy for
yourself?
Diagnosis
 Inadequate energy intake(NI-1.4) related to
restricting food and purging as evidenced by
her underweight BMI of 17.48.
Intervention
 Nutrition-Related Behavior Modification
Therapy C-1
 A supportive process to set priorities, establish goals
and create individualized action plans that acknowledge
and foster responsibility for self-care by setting goals
for Paris
 From Paris’ description and 24 hr. food recall we
determined that Paris has anorexia nervosa with
binge/purge tendencies.
Education Intervention
 Teach Paris the hunger/fullness scale
 Learn not to classify foods as good versus bad
 Discuss physical activity in terms of health rather than using it to
control her weight
 Discuss with her the idea about trusting her body to fluctuate between
a goal range weight for her
 Gradually increase her caloric intake to prevent refeeding syndrome
 Teach her to add foods that she considers “safe” into her diet. She
stated she felt “safe foods” were all vegetables and salads.
 Although we intend to attempt to try these intervention techniques with
Paris, we realize that this may be an extremely slow process and take a
very long time depending on how she reacts to treatment.
Sample Diet
 2 eggs, 1 C granola, 1 C skim milk
 1/2 C grapes
 2 oz turkey on 2 slices whole wheat bread, light
mayo, mustard, 2 slices tomato, lettuce
 1 C apple juice
 2 cups mixed green salad, 2 oz tuna, 4 slices
cucumber, tomato, carrots, balsamic dressing
 This diet is low in calories and not meant for the
long term, but it can be a good place to start.
Action Goals
1. Have Paris choose one food item of her choice at
every meal. This can be a vegetable, fruit, or
anything she wants.
2. To better understand intuitive eating, have her read
a chapter a week from Intuitive Eating (Tribole,
Resch, 1995) and focus her behavior change on
that particular chapter.
3. Have Paris keep a journal of her feelings prior and
post eating.
Outcome Goals: Goal Weights
 Paris should aim to gain about 1 lb. per week,
however this may be unrealistic at first, and that is
alright in the beginning, as long as she does not
lose any more weight.
 Goal: 140 lbs. based upon Hamwi
 1 Month Goal: 119 lbs.
 3 Month Goal: 131 lbs.
 1 Year Goal: 126-154 lbs.
 Insure a slow and steady weight gain to prevent
refeeding syndrome.
Follow-Up
 Follow up with Paris in one week due to
being in the beginning stages of treatment.
 Then follow-ups may occur every two
weeks.
 Have weekly talks/meetings with the other
healthcare professionals on the team
(physician, psychologist, etc)
