2  Obesity is an abnormal increase in the proportion of fat cells  Primarily occurs in the visceral and subcutaneous tissues of the body  Second leading cause of preventable death  Third leading reason for liver transplantation

3  Body mass index (BMI) – see chart, p. 945  Waist circumference › People with excessive visceral fat in waist are more prone to cardiovascular disease and metabolic syndrome  Waist-to-hip ratio (WHR) › Waist measurement is divided by hip measurement › A WHR measurement >.08 is at risk for complications

4  What is considered to be normal BMI?  What is classified as overweight?  What is considered obese?

5 Health risks increase if the waist circumference is >____ in a female and >____ in a male?

6  Body Shape › Pear shape have more sub-q fat › Most fat is below the waist

7  Apple shape have more visceral, abdominal fat and are prone to:  Elevated triglycerides  Metabolic syndrome  Decreasing insulin sensitivity  High levels of HDL cholesterol  Increasing blood pressure  Release of more fatty acids into the bloodstream

8  Genetic/Biologic basis  Environmental factors  Psychological factors

9  Problems occur at higher rates for obese patients  Mortality rate rises as obesity increases › Especially with increased visceral fat  Obese patients have a decreased quality of life  Most conditions improve with weight loss

10

11  Also know as Insulin Resistance  Diagnostic Criteria: › Increased Waist circumference › Elevated Triglycerides › Elevated HDL › Elevated Blood Pressure › Fasting Blood Glucose > 110mg/dl  These people are at risk for heart disease, stroke, Diabetes, renal disease

12  Modify eating patterns  Participate in a regular physical activity program  Achieve weight loss to a specified level  Minimize or prevent health problems related to obesity

13

14

15  Nutritional Therapy › Low calorie with adequate amounts of fruits and vegetables, bulk, and meets daily vitamin requirements › Avoid fad diets › Small Portions  Exercise › 30 minutes to 1 hour per day

16 Patients desire to change lifestyle + Exercise + Diet control Weight Loss

17

18  Used to treat morbid obesity  Currently the only treatment found to have a successful and lasting impact for sustained weight loss

19  Must meet all of the following criteria to be considered an ideal candidate › BMI ≥40 kg/m 2 with one or more obesity-related complication › 18 years or older › Understands the risks and benefits › Has been obese for >5 years › Has tried and failed to lose weight

20  Three broad categories › Restrictive › Malabsorptive › Combination of restrictive and malabsorptive

21

22  Have room ready for patient prior to arrival making adjustments in equipment and supplies  Skin Preparation  Teach T,C, DB and exercises  IV access

23  Trained staff should assist transfer of unconscious patient. During transfer ensure that patient’s › Airway is stabilized › Pain is managed  Assess of vital signs. › What is of particular concern ?  Keep bed at 30 0 – 45 0

24  T,C, DB – being sure to splint incision. › Why is so important? › What is a complication if does not splint incision?  Pain Management  TED hose and pneumatic compression devices

25  Rapid oxygen desaturation  Wound evisceration and dehiscence  Wound Infection

26  Dumping syndrome – gastric contents empty too rapidly into the small intestine  Symptoms – vomiting, nausea, weakness, sweating, faintness, and diarrhea  Prevention – eat small meals; avoid high CHO foods/concentrated sweets and no fluids with meals  Iron Deficiency anemia

27

28  Expected outcomes › Long-term weight loss › Improvement in obesity-related co- morbidities › Integration of healthy practices into lifestyle › Monitoring possible adverse side effects › Improved self-image
