The Basic Human Physiological
Equation:
• Ratio of calories consumed to calories used
• Consumed vs Used
• Eat more than activity uses? = weight increase
• Activity uses more than consumed? = weight decrease
• There is no magic!
• There are no secrets
SO WHY PEOPLE ARE OBESE?
ADDITIONAL FACTORS
So Why People Are Obese?
Increased energy intake
 Foods are cheaper than decades
ago
 Bigger portions
 Due to cheaper costs
 Bigger crop yields
 Easier for food industry to ‘supersize’ you
 Bigger sizes
 Fruits are larger in size
 McDonalds Soft drinks sizes 1974
 8, 12 & 16 ounce
 21st century foods are more nutritious
than even 50 years ago
 Comparable foods might have more
nutrition per volume
 Better apples, rice, beef, etc.
So Why People Are Obese?
Decrease in Physical
Activity
 Physical activity was MUCH greater
in a horse drawn world
 Labor Saving devices require less
human caloric use
Fear of activity
 “Children cant walk to school, they
might be kidnapped”
 “I don’t want my child to get hurt
on the playground”
 “I cant exercise because I have;
asthma, autism, ADD, etc, etc, etc .
. . .”
 Is there a safe place to be active?
 Adults or children
So Why People Are Obese?
Genetics
You are alive today
because your
ancestors SURVIVED …
 Disease
 Disasters
 FAMINE!
Does your body hold on to
consumed calories better
than a genetic line that
never experienced
famine?
Were you raised in a family
that eats heavily?
 Adopted children can
become obese
So Why People Are Obese?
Ethnic & Socioeconomic
factors
 Food quality and portion size in
the old country
 Ethnic adaptations to new food
items
 How does a body change from
eating rice to potatoes?
 Foods available in different
parts of town
 Quality of fruits & vegetables
 Items stocked at ‘local market’
 Is local market a grocery store?
Or a liquor store?
 Most protein foods are
expensive
 Greater number of calories from
fats & carbohydrates
 Working a 12 hour day?
 Fast food more likely than a
prepared meal
 Fast food can change the ratio of
calories
 Fats, carbohydrates, proteins
So Why People Are Obese?
Stress
 Boredom?
 Anger?
 Depression/sadness?
Comfort food
seeking
 Greater volume of food
intake
 Comfort food high in
fats & carbohydrates
So Why People Are Obese?
Hormones
 Hypo-Thyroid
 Slowed metabolism
 Feeling weak & tired
 Cushing's
disease/syndrome
 High levels of Cortisol
 “I have a glandular
problem”
 polycystic ovarian
syndrome
 High levels of androgens
CNS Damage
 Pituitary imbalances
So Why People Are Obese?
Drugs - Pharmacology
 Glucocorticoids (dexamethasone)
 Antidepressants
 Phenothiazines (antipsychotic)
 Some beta-blockers
Less likely to lead to obesity . . .
Age
 Age slows activity
 Need to reduce caloric intake
 Menopause
 Weight gain
Quantifying Fat and Obesity?
BMI: Body Mass Index
 A weight-to-height ratio, calculated by dividing one's
weight in kilograms by the square of one's height in meters
and used as an indicator of obesity and underweight.
Quantifying Fat and Obesity?
Underweight: <18.5
Normal Weight: 18.5 24.9
Overweight: 25 - 29.9
Obesity: 30 - 34.9 (I)
Obesity: 35 - 39.9 (II)
Extreme Obesity: >40
(III)
 10-15% reduction in weight
has significant positive
effects on health
Save the Children
1 in 5 obese (6 to 17 years
of age)
More than doubled in the
last 30 years
Decreased physical
activity
Increased soda, junk food,
video games, TV
Increased chronic disease
onset
The Statistical Mystery
• Obesity = health problems?
• YES!
• BMI of 27 or higher = increased morbidity and mortality
• However as America’s weight increases, so does it’s life
expectancy . . . . ?
Obesity Complications
Increased likelihood of:
NIDDM or Type 2 DM
HTN
CAD, heart disease, hypertriglyceridemia
CVA
CA (prostate, colon, breast)
Sleep Apnea
Osteoarthritis
Fatty liver disease
Metabolic Syndrome
People who have 3 out of 5:
 Abdominal obesity
 Men > 40 inches
 Women > 35 inches
 HTN
 High fasting BG
 Low levels of HDL
 High serum triglycerides
Increases their risk for:
 Heart disease
 Stroke
 Diabetes
Sleep Apnea
Higher BMI correlated with sleep apnea
Use of adjuncts at home and on the job
 O2
 Bipap
 CPAP
Increased risk of hypoxia, CHF, Motor Vehicle Crashes
Medical Specialty
• Bariatricians and the Journal of Bariatric Medicine:
“Obesity is a chronic, debilitating and potentially fatal disease
that requires the treatment by a physician trained in
bariatric medicine
Treatment of Obesity
Exercise
Psychological Intervention
Diet and Very Low Calorie Diet
Hormone Therapy
Drugs
Surgery
Treatment of Obesity
Exercise
• Increased activity affects basic
physiological ratios
• Does intake = outgo?
• However . . .
• Lifestyle is a learned behavior
• Can people make meaningful
sustainable changes?
• Sedentary Occupation?
• Preferred recreation?
• Social Structure?
Treatment of Obesity
Psychological Intervention
• “Why do you overeat?”
• Depression?
• Stress?
• Lack of nutritional knowledge . . . . ?
• Possibility for some behavioral changes
• Overeaters anonymous – 12 steps to weight control
Treatment of Obesity
Diet and Very Low Calorie Diet
• Reduce general food intake? Excellent
strategy . . .
• However you cant starve your way to health
• Are sustainable behavioral changes
realistic?
• Severe dieting needs medical supervision
Complications of VLCD
 Nutritional Deficiencies
 Consumed food must be nutritionally balanced
 Fats, carbs, proteins, vitamins, minerals . . . .
 Increased risk of gallstones
 Greater than 10 lb weight cycle (chronic dieters)
= higher risk for gallstones
Gallstones
Classical Gallstones
URQ pain
Right shoulder, shoulder blade pain
N/V
Dyspepsia after desert, fish and chips
Dieter’s Gallstones
Weight loss > 3 lbs per week = higher incidence
VLCD: 1/3 of dieters developed gallstones
Shift in bile salts and cholesterol
Cholesterol increased
Bile salts decreased
Skipping meals may decrease gallbladder contractions
Stagnation = coagulation or gallstone formation
Treatment of Obesity
Pharmacological Treatment
 Amphetamines
 Amphetamine, dextroamphetamine, methamphetamine
Appetite Suppressants
 Phentermine (Adipex, Fastin, Banobese, Obenix, Zantryl)
Orlistat (Xenical): lipase inhibitor
 Requires vitamin supplement (A,D,E,K and beta carotene)
Leptin: hormone that may suppress appetite
Treatment of Obesity
Hormone Therapy?
• Possible future treatment - Needs greater research
• Treatment for known disorders?
• Thyroid
• Direct supplementation?
• Gut hormones
• Might modify hunger impulse . . . .
Treatment of Obesity
Surgical Treatment of Obesity
From Peptic Ulcers to the Lap Band
First Gastric Bypass 40 years ago
Risks:
 Surgical experience
 Sleep apnea
 DM
How it works:
 Food Restriction
 Malabsorption
The Stomach Is Made Smaller
• Laparoscopic surgeries
• Lap Band
The Stomach Is Made Smaller
• Gastric Bypass
• Duodenal bypass
• Roux and Y
• And many more! (depends
on local physician/surgeon
education/training)
The Stomach Is Made Smaller
• Gastric Bypass
• Duodenal bypass
• Stapling and excision

 Diarrhea
 Abdominal pain, cramps
 Bloating, belching, flatulence
 Anxiety, nervousness, fainting
 Palpitations, rapid heart rate
 Sweating
 Mental confusion
Why Even Do Surgery?
• Surgery more effective than other weight loss
programs
Obesity and Prehospital Care
• Fact: There exist a universal
prejudice against bariatric
patients in occupations
that are responsible for
lifting and carrying them
• Fact: The (unaided)
movement of a bariatric
patient can result in a
career ending injury
• Just as pediatric patients
are not little adults,
bariatric patients have their
own special needs and
medical complications.
Psychosocial Considerations
Both You and the Patient!
• Bariatric patients have
both a physical AND
mental problem
• They know they are ‘FAT’
• They are addicted to food
• You cannot cure them!
(think of them as an
alcoholic)
• The person who has not
been out of their house
for years has a (codependent) family or
friend who brings them
food
Psychosocial Considerations
Both You and the Patient!
• Acknowledge the stereotypes
• Acknowledge YOUR feelings
• They are still human
• Use dignity and compassion
• However - Don’t them end your career
Prehospital Bariatric Assessment
• Keep patient upright
• Easier breathing
• Sample lung sounds near scapula
• Decreased Adipose tissue
• Pulse oximeter
• Earlobe, little finger, nose
• Cyanosis
• Lips and eyelids
• Proper sized B/P cuff?
• EKG leads - avoid anterior
abdomen
• Lateral aspect of abdomen
Bariatric Airway
• High risk for aspiration
• Large stomach size
• Decreased gastric pH
• Need EXCELLENT oxygenation
• Decreased O2 reserves
• No toleration for apnea
• BVM is a 2 person job
• Additional tissue weight must be displaced
• Elevate head to 25 degrees (towels
under back)
• Towel between scapula can displace
breasts
• CPAP – BiPAP can be effective
• Set to at least 10 cm H2O to improve
effectiveness
Bariatric IV Access
• Landmarks are difficult to find
• Multiple sticks common – are the
complications worth it?
• Consider deferring in field
• Catheters longer that 1.5 inches?
• Consider earlier IO access
• Longer IO needles exist
• Medications
• Renal problems may cause blood levels to
be higher or lower than expected
• Lipophilic drugs may result in lower serum
levels and slower elimination
• Fentanyl - benzodiazepines
Obesity and Trauma
4-6 L of blood per person
Larger size does not equal larger blood supply
Increased metabolic demand from more cells
May have worse response to trauma
Spinal Stabilization
• Even normal people don’t fit on backboards!
• Complete immobilization is unrealistic
• Minimize ‘excessive movement’
• Cervical collar may affect airway
• Monitor carefully
• Field spinal clearance?
Logistics
• Proper sized stretchers
• Weight capacity
• WIDTH also!
• Can (interfacility) bariatric
equipment be brought to a 911
call?
• Patient safety may be worth the
wait
• Have adequate staff for lifting
4? 6?
• Ensure/survey a clear path to
ambulance
• Bariatric tarps
Final Thoughts
• Man’s 1000 year progress in fighting starvation has
resulted in an obesity situation in the modern world
• It is not going to be changed anytime soon
• You cannot cure a bariatric patient!!
• They require specialized equipment and
procedures
• Whatever you do, whatever treatment you provide,
they are always at higher risk for death
• Follow standardized procedures and don’t allow a
bariatric situation to end your career
