Paris’ Description • She tried to stop restricting her intake of food and purging on her own but once she experienced stress she reverted back to her old coping mechanisms. • She was hospitalized while in law school for a weekend because of severe dehydration but released after 24 hrs.
Paris’ Description • She appears emaciated • She appears tired and older than age 34 • She loves to cook but gives most of the food away • She admitted that she knows she has a problem dealing with food and eating
Paris’ Anthropometrics • Height: 5’8 • Weight: 115 lbs. • BMI: 17.48 • Interpretation: underweight
Basal Energy Metabolism • Harris Benedict: 655 + (9.6 x 52.8) + (1.8 x 172.72) – (4.7 x 34)= 1313 x activity factor(1.3)= 1707 KCALS
Paris’ 24 Hr. Recall • AM: ¼ whole wheat bagel, 4 oz. calcium fortified orange juice, 6 oz black coffee • Lunch: Black coffee 2-3 c • Afternoon snack: 12 oz can Diet Coke • Dinner: 6 green peas, 18 oz water • Snack: 12 oz Diet Coke
Nutrition Problems • Rough dry skin with lanugo • Bruising • Brittle finger/toenails • Erosion of dental enamel • Multiple food allergies • Gastric/abdominal problems • Easy Bleeding/anemia
Paris’ Lab Value Results • Low albumin of 3.0 L • Low pre-albumin of 14.5 L • Low potassium of 3.0 L • Low magnesium of 1.7 L • High glucose of 115 H • High CPK of 146 H • High HDL of 60 H • Low WBC of 4.6 L
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)
Parameters to measure • Weight • Coping mechanisms • Monitor purging behavior • Continual discussion with the other members of the treatment team for Paris
