Anorexia Nervosa
The patient with anorexia nervosa refuses to eat adequate quantities of food and is in danger of literally starving to death
Diagnosis requires extensive interviewing, and treatment—including behavior modification and nutrition support—which may take months to years
7

Bulimia Nervosa
The bulimic patient consumes large quantities of food and then induces vomiting to get rid of it so that weight is not gained
Laxatives Some patients with anorexia nervosa also are
bulimic Some individuals practice bulimia
occasionally without harm
8

Obesity
Etiology and pathophysiology Signs and symptoms Diagnosis
Height and weight chart Waist and hip circumference Body mass index (BMI)
10
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Obesity Treatment
Bariatric surgery Extensive counseling and assessment Modify lifestyle and stringent regimen required to
lose weight and keep weight off Types
• Gastric restrictive
• Malabsorptive
• Gastric restrictive combined with malabsorptive surgery
11
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Bariatric Surgery
Preoperative care There is greater risk of pulmonary and thrombus
formation, as well as death, for the obese patient
12
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Restrictive Procedures
Laparoscopic adjustable gastric banding is performed by placing an inflatable band around the fundus of the stomach
The band is inflated and deflated via a subcutaneous port to change the size of the stomach as the patient loses weight
13
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Restrictive Procedures (cont.)
For vertical banded gastroplasty, the surgeon creates a small stomach pouch by placing a vertical line of staples
A band is placed to provide an outlet to the small intestine
14

Gastric Bypass
15
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Vertical Banded Gastroplasty
16

Circumgastric Banding
17
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Malabsorptive and Combination Procedures
The total gastric bypass procedure causes severe nutritional deficiencies and is no longer recommended
The roux-en-Y gastric bypass (RYGB) limits the stomach size, and the duodenum and part of the jejunum are bypassed. This limits the absorption of calories
18
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Complications
Leakage of stomach contents Gastric stretching Dumping syndrome Nutritional deficiencies—iron, vitamin B12,
calcium, and folate
19

Cigarette smoking is a major cause of esophageal cancer in the United States
When combined with heavy alcohol consumption, the risk for esophageal cancer greatly increases

Hiatal Hernia (Diaphragmatic Hernia)
Etiology and pathophysiology Signs and symptoms Treatment
31
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Treatment of Hiatal Hernia
Reduce weight Avoid tight-fitting clothes around the
abdomen Take antacids and histamine (H2)-receptor
antagonists Elevate head of the bed on 6- to 8-inch
blocks Take proton pump inhibitors
32
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Treatment of Hiatal Hernia (cont.)
Instruct not to eat within several hours of going to bed
Limit intake of alcohol, chocolate, caffeine, and fatty foods
Avoid smoking
33
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Nursing Management
Teach ways to prevent pain and reflux Encourage weight reduction Remind the patient to stay upright for 2 hours
after eating and not to eat for 3 hours before bedtime
34
Elsevier items and derived items © 2013, 2009 by Saunders, an imprint of Elsevier Inc.
Nursing Management (cont.)
If the head of the bed cannot be raised, a wedge pillow should be used to elevate the upper body; this position helps prevent reflux and assists gravity in maintaining the stomach in the abdominal cavity
H2 or proton pump inhibitors Avoid foods that cause bloating
