Impact of Obesity: Social and Economic Effects

• • Social Impact – – – Getting a job, making a good impression Dealing with judgmental behavior Compromising health and premature aging Economic Impact* 1-6 – As weight increases, so does medical spending in the health care system – – – – $139 billion in direct and indirect costs annually Annual costs for obesity are ~15× greater than those for being overweight Increased personal spending on prescriptions, weight-loss products By 2030, health care costs attributable to overweight/obesity could account for 16% to 18% of total US health care costs Costs Associated With Obesity 1 14.5% *Regression approach using data from 1998 Medical Expenditure Panel Survey and the 1996-97 National Health Interview Surveys.

Why Current FDA-Approved Weight-Loss Drugs May Not Work

• • • May not sustain long-term weight loss in most patients 1,2,3 – Average weight loss with medication is only 5% to 10% 1,4 – Obesity is a complex condition with multiple underlying causes – Medication may not be targeting all the mechanisms driving hunger and cravings Hunger is not the only trigger for eating – Other powerful forces drive eating – comfort eating, social eating – Food is not used solely for nutritional reasons – Genetics and impaired metabolism Side effects can interfere with compliance and increase dropout rates – Cause insomnia, drowsiness, irritability, or depression 1 – Fat absorption drugs can cause muscle cramping, diarrhea, flatulence, and intestinal discomfort 1 – Consuming excess amounts of fat while taking those drugs may cause greater intestinal discomfort

Still… benefits may outweigh risks when evaluating weight-loss programs and pharmacotherapy

Gastric Banding Often Enables a Healthy Rate of Weight Loss

Gradual weight loss with gastric banding

• Healthy weight loss • Similar to diet and exercise • Excess fat is lost

Rapid weight loss with gastric bypass

• Excess fat lost • Muscle, bone and necessary fat lost • Nutrients and minerals lost • Nutrient supplementation is necessary to prevent other health problems Chaston TB et al

. Int J Obes (Lond)

. 2007;31(5):743-750.

42

Importance of Fat-Free Mass Loss (FFML)

• • • • Fat-free mass plays an important role in preservation and regulation of the body.

– Preserves skeletal integrity and quality of life as the body ages, and maintains resting metabolic rate, as well as regulates core body temperature With significant weight loss, patients may lose fat-free mass such as bone or muscle mass, nutrients or necessary fat. Certain bariatric surgical methods can cause malabsorption and malnutrition, which influence fat-free mass loss.

Nondiversionary LAGB surgery generally preserves a favorable amount of fat-free mass.

. 2007;31(5):743-750.

43

Gastric Band: Lower FFML Than RYGB

* LAGB Patients (n=400) lost a median of 17.5% fat-free mass 8% of cohort (n=400) experienced above-average FFML † RYGB Patients (n=87) lost a median of 31.3% fat-free mass 100% of cohort (n=87) experienced above-average FFML † *The mean %FFML was calculated for all male subjects and all female subjects on dietary and behavioral weight loss interventions. Where studies reported a mean of male subjects and female subjects, the cutoff was adjusted in proportion to the ratio of female subjects to male subjects in the study.

† Average FFML was defined by the mean %FFML of subjects on dietary and behavioral weight loss interventions.

LAGB Is Cost Effective in the Long-Term Using Claims Analysi s •

US health care claims data for 7000 LAGB patients were used to quantify the costs and potential cost savings resulting from LAGB

Including the related medical payments in the 90 days before and after the procedure, the mean cost of LAGB was approximately $20,000

The net cost of coverage for LAGB was reduced to 0 by approximately 4 years after band placement in the general population

For those with diabetes, the net costs resulting from LAGB were reduced to 0 in just 2 years Finkelstein EA et al.

Amanda’s Success Story

Before After

“After years of yo-yo dieting, gaining back even more weight every time I quit, I gave up. At 304 lbs, I thought I was out of weight loss options. Then I learned about the LAP-BAND ® System weight loss surgery and I knew right away it was the best choice for me. Since my surgery in 2003, I've gone from a size 30 dress down to a size 14. I feel so great about my decision, my positive lifestyle changes, and even better about my results. Best of all, I look like a new woman and I'm in control of my life!”

Duane’s Success Story

Before After

“My moment of truth was when I hit 303 pounds. I knew right then I had to do something or I wasn’t going to be around to see my girls grow up. Now I get to have fun and my kids love it. The greatest feeling I ever had was when my kids could come up to me and put their arms completely around me for the first time. A year ago we had a class reunion and nobody knew who I was. That was cool. I had this one girl say “Duane, you look hot.” And I said, “why didn’t you think that 30 years ago?” Getting the LAP-BAND ® System surgery was the greatest decision I ever made in my life.”

The Role of the Primary Care Physician

49

50

The Physician’s Role •

Diagnose – Recognize patients at risk – Calculate BMI, which may be estimated to be lower than actual value

Educate about obesity – Inform patients of health risks and medical hazards associated with severe obesity – If lifestyle recommendations are not able to be consistently followed, then one should consider a bariatric procedure – Describe impact of weight loss on comorbidities and mortality – Communicate weight loss results and importance of long-term follow-up

The Physician’s Role

(cont’d)

Motivate patients to address obesity – Describe tangible options available to patients – Share success stories

Explain surgical options – LAGB has a lower rate of complications compared to other bariatric procedures 1,2 – LAGB is effective for weight loss with data out to 5 years 3 • Lower FFML compared with RYGB (17.5% vs 31.3%) 4 4/24/2020 51

The Physician’s Role

(cont’d) – Weight loss with LAGB often improves major cardiovascular risk factors as well as other comorbidities 5 •Hypertension •Hyperlipidemia •Type 2 diabetes •Asthma •GERD •Obstructive sleep apnea 1. Parikh MS et al.

The Physician’s Role

(cont’d)

Refer patient to better understand surgical options – Important to select an experienced surgeon in a comprehensive, weight loss center with competed support staff, able to care for patients afflicted with obesity.

Aftercare management

– To enhance the transition to life after bariatric surgery and to prevent weight regain and nutritional complications, all patients should receive care from a multidisciplinary team including an experienced primary care physician, endocrinologist or gastroenterologist and consider enrolling postoperatively in a comprehensive program for nutrition and lifestyle management.

Bariatric Surgery Guidelines Support Your Referrals

• Nonsurgical treatments ineffective for most morbidly obese patients 1 • The American Academy for Clinical Endocrinologists, the Obesity Society, and the American Society for Metabolic & Bariatric Surgery have recommended that morbidly obese patients (BMI >40 or BMI >35 with a obesity related comorbidity) should be offered bariatric surgery.

2 – 15 million individuals meet the criteria for morbid obesity 3 • American Diabetes Association: Bariatric surgery should be considered for adults with BMI of 35 and type 2 diabetes, especially if the diabetes is difficult to control with lifestyle and pharmacologic therapy.

Weight (adults) Weight loss history Commitment Exclusion

Criteria

• • BMI ≥40 with no comorbidities BMI ≥35 with one or more severe obesity-associated comorbidity • Failure of previous nonsurgical attempts at weight reduction, including nonprofessional programs (for example,

WeightWatchers

® ) • • • • Expectation that patient will adhere to postoperative care Follow-up visits with physician(s) and team members Recommended medical management Instructions regarding any recommended procedures or tests • • • • • Reversible endocrine disorders or other disorders that cause obesity Current drug or alcohol abuse Uncontrolled, severe psychiatric illness Unable to comprehend – Risks, benefits, expected outcomes, alternatives, and required lifestyle changes Not a complete list of exclusion criteria for bariatric surgery 1.

Consider Early Intervention

• Early intervention with the Band System in obese and moderately obese patients has recently been approved by the FDA.

• The gastric band has been shown to be safe and effective in individuals with a BMI of 30 to 40 with obesity-related comorbidity.

• Majority of patients (>80%) achieved >30% EWL – Mean 65% EWL at 1 year • Laboratory values improved • Quality of life measures were significantly improved • New data supports the need for primary care physicians to refer obese and moderately obese individuals who fail other forms of weight loss management for bariatric surgery.

Summary

The gastric band is a safe and effective option for your obese to morbidly obese patients whose weight is affecting their health • Fewer complications compared with gastric bypass reported in 1 study 1 • – 9% ( LAP-BAND ® , n=480) vs 23% (RYGB, n=235) Comparable weight loss to gastric bypass after 5 years 2 • – 55% ( LAP-BAND ® , n=640) vs 58% (RYGB, n=176) More cost-effective than gastric bypass 3 – Payers estimated to fully recover the costs of laparoscopic bariatric surgeries after 2 ¼ years in patients with diabetes and after 4 years in the entire surgical population 4 1.
