THE DISEASE OF OBESITY
In the news…
Obesity extends duration of influenza A virus sheddingvAug 2, 2018
vObesity increases influenza disease severity & also extends by about 1.5 days how long the virus is shed.
Obesity increases risk of premature deathvJuly 2016
vHarvard study demonstrated that every 5 units higher BMI above 25 kg/m2 was associated with 31% higher risk of premature death.
According to the CDC in 2015-2016v39.8 % US population affected by obesityv93.3 million adults in USvEstimated cost (in 2008) was $147 billion
https://www.cdc.gov/obesity/data/adult.html [accessed 1 Aug 2018]accessed 7 Aug 2018)
Impact on Mortality
Obesity is associated with a 50-100% risk of premature death compared to healthy weight individuals.
vMedian survival rate is reduced by two-four years for individuals with BMI 30-35
vMedian survival rate is reduced by eight-to-ten years for individuals with BMI 40-45 which is comparable to smoking.

Definition of Obesity
“Obesity is defined as a chronic, relapsing, multi-factorial, neurobehavioral disease, wherein an increase in body fat promotes adipose tissue dysfunction and abnormal fat mass physical
forces, resulting in adverse metabolic, biomechanical, and psychosocial health
consequences.”

Motivational Interviewing: Focus
Collaboration
• Working together to find and implement pragmatic solutions
• Not focusing on who is right and who is wrong
Evocation
• Drawing out the patient’s thoughts and ideas regarding solutions
• Not telling the patient what to do
Autonomy
• Empowering the patient to own the solution
• Not the authoritarian power of the clinician
Obesity Algorithm®. ©2017-2018 Obesity Medicine Association.
All or nothing
Motivational Interviewing Techniques: 5A’s of Obesity Management
• Ask for permission to discuss body weight.• Explore readiness for change.Ask
• Assess BMI, waist circumference, and obesity stage.• Explore drivers and complications of excess weight.Assess
• Advise the patient about the health risks of obesity, the benefits of modest weight loss (i.e., 5-10 percent), the need for long-term strategy, and treatment options.
Advise
• Agree on realistic weight-loss expectations, targets, behavioral changes, and specific details of the treatment plan.Agree
• Assist in identifying and addressing barriers; provide resources; assist in finding and consulting with appropriate providers; arrange regular follow up.

Food and Drug Administration (FDA) Principles
FDA-approved Anti-obesity Medication Indications:vPatients with obesity (e.g., BMI > 30kg/m2)
vPatients who are overweight (e.g., BMI > 27kg/m2) with presence of increased adiposity complications (e.g., type 2 diabetes mellitus, hypertension, dyslipidemia)*
vAnti-obesity medications are contraindicated in patients hypersensitive to the drugs
*If no clinical improvement (e.g., at least 4 - 5% loss of baseline body weight) after 12-16 weeks with one anti-obesity medication, then consider alternative anti-obesity medication or increasing anti-obesity medication dose (if applicable).

Drug Description Main Side Effects Drug InteractionsPhentermine Phentermine was approved in
1959, and is the oldest available approved anti-obesity drug. It is a DEA Schedule IV stimulant agent approved for short-term use (12 weeks). Some patients may lose about 5% of body weight.
Side effects include headache, high blood pressure, rapid or irregular heart rate, overstimulation, tremor, and insomnia. Should not use with overactive thyroid or uncontrolled high blood pressure or seizure disorder. Contraindicated in patients with history of cardiovascular disease, within 14 days of monoamine oxidase inhibitors, glaucoma, agitated states, drug abuse
Monoamine oxidase inhibitors, sympathomimetics, antidepressants, alcohol, adrenergic neuron blocking drugs, and some anesthetic agents
Orlistat Orlistat impairs digestion of dietary fat. Lower doses are approved over-the-counter. Some patients may lose about 5% of body weight.
Side effects include oily discharge with flatus from the rectum, especially after fatty foods. (May help with constipation.) May promote gallstones and kidney stones. Will need to take a multivitamin daily. Contraindicated in chronic malabsorption syndrome and cholestasis.
Cyclosporine, hormone contraceptives, seizure medications, thyroid hormones, warfarin
Lorcaserin Lorcaserin is a DEA Schedule IV agent that improves the sense of fullness. Some patients may lose 5 – 10% of body weight.
Lorcaserin is a generally well-tolerated drug, with headache, dizziness, fatigue, nausea, dry mouth, and constipation occurring more frequently compared to placebo. Warnings and Precautions include serotonin syndrome, heart failure, psychiatric disorders, and priapism.
Serotonergic (SSRI’s, SNRI’s, MAO inhibitors) or anti-dopaminergic medications, St John’s wort, triptans, bupropion, dextromethorphan, CYP 2D6 substrates
Anti-Obesity Drug Summary (All have contraindications for hypersensitivity and pregnancy)
Obesity Algorithm®. ©2017-2018 Obesity Medicine Association.
Drug Description Main Side Effects Some Drug Interactions
Liraglutide Liraglutide is an injectable drug, that in lower doses (1.8 mg per day), is also used to lower blood sugar. Some patients may lose 5 – 10% of body weight with the higher dose of the liraglutide 3.0 mg per day, which is the dose approved for treatment of obesity.
Adverse reactions include nausea, hypoglycemia, diarrhea, constipation, vomiting, headache, decreased appetite, dyspepsia, fatigue dizziness, abdominal pain, increase lipase, and renal insufficiency. Contraindicated with personal of family history of medullary thyroid cancer or Type 2 Multiple Endocrine Neoplasia syndrome. Discontinue with suspected pancreatitis, gall bladder disease, or suicidal behavior and ideation.
May slow gastric emptying, which may impact absorption of concomitantly administered oral medication.
Naltrexone / bupropion
This is a combination of naltrexone (opioid antagonist used for addictions) and bupropion (used for depression and smoking cessation). Some patients may lose 5 - 10% of body weight.
Naltrexone / bupropion can cause nausea, constipation, diarrhea, and headache. The bupropion component is an antidepressant, and antidepressants can increase the risk of suicide thinking in children, adolescents, and young adults; monitor for suicidal thoughts and behaviors. Should not be used in patients with uncontrolled high blood pressure, seizure disorders, or drug/alcohol withdrawal.
Opioid pain medications, anti-seizure medications, MAO inhibitors, and possible drug interactions with other drugs.
Phentermine / topiramate
This is a combination of phentermine (anti-obesity drug) and topiramate (used to treat seizures and migraine headaches). This DEA Schedule IV drug is approved as a weight management pharmacotherapy. Some patients may lose 5 – 10% of body weight.
Phentermine / topiramate can cause tingling or numb feelings to extremities, abnormal taste, insomnia, constipation, and dry mouth. Should not be used in patients with glaucoma, uncontrolled high blood pressure, heart disease, or hyperthyroidism. Topiramate can cause birth defects. Therefore, phentermine / topiramate should not be started until a pregnancy test is negative, unless the woman is using acceptable contraception, and pregnancy tests should be done monthly during use.
Monoamine oxidase inhibitors. May alter oral contraceptive blood levels.
