The Certified Specialist in Obesity and Weight Management (CSOWM) exam is an
advanced, interdisciplinary certification administered by the Commission on
Dietetic Registration for healthcare professionals specializing in obesity care. This
rigorous assessment evaluates comprehensive knowledge of the pathophysiology
of obesity, nutritional biochemistry, behavioral modification, pharmacotherapy, and
surgical interventions. Candidates must demonstrate mastery in assessing patients
across the lifespan, identifying metabolic complications, interpreting laboratory
data, and developing individualized treatment plans. The exam covers preoperative
and postoperative bariatric care, nutrient deficiencies, weight regain prevention,
and managing comorbidities such as diabetes and hypertension. Earning the
CSOWM credential signifies clinical excellence and a commitment to evidence-
based, patient-centered obesity management.
1. A 48-year-old woman with class III obesity who had Roux-en-Y surgery six
weeks ago presents to the emergency department. Since surgery, she has had poor
food and fluid tolerance requiring IV hydration. Review of systems finds nausea,
vomiting, edema, numbness, new unpleasant sensation in her feet and legs, and
brain fog. Which dietary deficit is the most likely source of her symptoms?
A) Folate deficiency
B) Thiamine deficiency
C) Vitamin B12 deficiency
D) Iron deficiency anemia
Answer: B
,Rationale: Thiamine (vitamin B1) deficiency can present with neurological
symptoms including neuropathy (numbness, paresthesia), confusion or brain fog,
and cardiovascular symptoms. Post-bariatric surgery patients are at particular risk
due to reduced intake and malabsorption, especially with persistent vomiting and
poor oral intake. The neurological manifestations described are classic for
Wernicke encephalopathy or thiamine deficiency neuropathy, which can occur
rapidly in the setting of poor nutrition after surgery.
2. A 52-year-old man with hypertension managed with medication struggles with
weight loss. Which antihypertensive drug is most likely to cause a 5%-10%
reduction in overall energy expenditure?
A) Enalapril
B) Losartan
C) Carvedilol
D) Metoprolol
Answer: D
Rationale: Metoprolol, a beta-blocker, can reduce overall energy expenditure by
5%-10%. Beta-blockers decrease sympathetic nervous system activity, which can
lower resting metabolic rate and reduce physical activity capacity. This effect can
contribute to weight gain or hinder weight loss efforts. ACE inhibitors (enalapril)
and ARBs (losartan) are generally weight-neutral. Carvedilol is a beta-blocker with
alpha-blocking properties that may have a more favorable metabolic profile
compared to metoprolol.
3. A 45-year-old Japanese-American man has a BMI of 23 kg/m², waist
circumference 36 inches (92 cm), normal blood pressure, and normal physical
exam. Compared to Caucasians, how should his risk of developing type 2 diabetes
be assessed?
A) Increased
,B) Decreased
C) Unchanged
D) Cannot be determined
Answer: A
Rationale: Asian Americans have an increased risk of developing type 2 diabetes at
lower BMI levels compared to Caucasians. The World Health Organization and
other organizations have recommended lower BMI cutoffs for identifying obesity-
related risk in Asian populations. A BMI of 23 kg/m² in an Asian individual may
carry similar metabolic risk to a BMI of 25 kg/m² in a Caucasian individual, and
the waist circumference threshold for increased risk is also lower.
4. Which bariatric procedure is increasingly being employed in the United States as
definitive treatment for severe obesity, including patients with BMI ≥ 60?
A) Sleeve gastrectomy
B) Roux-en-Y Gastric Bypass
C) Adjustable Gastric Banding
D) Vertical Banded Gastroplasty
Answer: A
Rationale: Sleeve gastrectomy has become increasingly common for severe obesity
due to significant and long-term weight loss with a simpler technical approach. It
involves removing a portion of the stomach to create a tubular stomach channel
without anatomical modifications to the small intestine. Roux-en-Y gastric bypass
still accounts for many bariatric surgeries, but sleeve gastrectomy has gained
popularity. Adjustable gastric banding has significantly decreased in use, and
vertical banded gastroplasty is no longer widely performed due to high
complication rates and insufficient weight loss.
5. Which of the following is a contraindication to bariatric surgery?
, A) BMI 30 kg/m²
B) Current substance or alcohol abuse
C) Obstructive Sleep Apnea
D) High-risk lipid profile
Answer: B
Rationale: Current substance or alcohol abuse is considered a contraindication to
bariatric surgery. Patients with active substance use disorders may have difficulty
adhering to the required lifestyle changes, nutritional supplements, and follow-up
care necessary for successful outcomes. BMI 30 kg/m² alone is generally not an
indication for surgery and is controversial. Obstructive sleep apnea and high-risk
lipid profile are comorbidities that may actually support the indication for surgery
when combined with a qualifying BMI.
6. What is the percentage of the clinically eligible population that undergoes
surgical obesity treatment?
A) 1%
B) 5%
C) 10%
D) 25%
Answer: A
Rationale: Only about 1% of the clinically eligible population undergoes surgical
obesity treatment. Despite the demonstrated efficacy of bariatric surgery for severe
obesity and its associated comorbidities, there remains a significant treatment gap.
Barriers include lack of access to surgical centers, insurance coverage limitations,
patient and provider knowledge gaps, and concerns about surgical risks.
