Study Notes
Eating Disorders Overview
- Adolescents (ages 12-25) with comorbid psychiatric disorders, especially depression, are at risk for developing eating disorders.
- Common physical signs include thin appearance, marked weight loss, amenorrhea, and unusual hair and nail brittleness.
- Other symptoms may involve arrhythmia, bradycardia, edema, hyperkeratosis, hypotension, lanugo, and early onset osteoporosis.
Diagnosis of Anorexia Nervosa
- Diagnosis relies on history, DSM-5 criteria, and Body Mass Index (BMI).
- Urine analysis evaluates hydration status and kidney function, measuring specific gravity, pH, ketones, and protein.
- Additional tests include monitoring body temperature, performing ECG, and conducting blood tests (CBC, electrolytes).
- Bone density assessment is critical to checking for osteoporosis.
Management of Anorexia Nervosa
- Managed by a collaborative care team including family, psychotherapy, and medical professionals (MD).
Prognosis for Anorexia Nervosa
- Approximately 50% achieve full remission, 30% partial remission, and 20% remain chronically ill.
- Mortality risk is 5.9 times greater compared to the general population.
Anorexia Nervosa DSM-5 Diagnostic Criteria
- Restriction of energy intake leading to significantly low body weight relative to age, sex, and physical health.
- Intense fear of gaining weight or becoming fat, despite being underweight.
- Disturbance in body image, self-evaluation influenced unduly by weight or shape.
Bulimia Nervosa Overview
- Characterized by recurrent binge eating episodes followed by inappropriate compensatory behaviors.
- Typical behaviors include self-induced vomiting, laxative misuse, fasting, or excessive exercise to prevent weight gain.
Bulimia Nervosa DSM-5 Diagnostic Criteria
- Binge eating episodes involve eating a larger portion of food within a discrete time period, accompanied by lack of control.
- Occurs at least once a week for three months and does not occur exclusively during anorexia episodes.
- Severity classification ranges from mild (1-3 episodes/week) to extreme (14+ episodes/week).
Management and Prognosis for Bulimia Nervosa
- Managed by a collaborative care team involving psychotherapy and psychiatric support.
- Recovery rates show 50-70% will improve or recover; however, the risk of suicide is increased by 4-7 times.
Binge-Eating Disorder Overview
- Defined by recurrent episodes of consuming large portions of food within a short time (≤2 hours), at least once a week for three months.
- Most prevalent in females, adolescents, and individuals who are overweight or obese.
Diagnosis of Binge-Eating Disorder
- Based on history and DSM-5 criteria focusing on the frequency of binge-eating episodes.
Management and Prognosis for Binge-Eating Disorder
- Collaborative care involving psychotherapy and medical professionals is employed.
- High resolution rate of 90% within five years, but 18% may continue to experience clinical eating disorders.
- Increased risk of obesity is associated with this disorder.
Binge-Eating DSM-5 Diagnostic Criteria
- Episodes marked by lack of control over eating and associated symptoms such as rapid eating, eating until uncomfortably full, and eating in isolation due to embarrassment.
- Distress regarding binge eating is also a significant component of the diagnosis.
Helicobacter pylori and Peptic Ulcer Disease (PUD)
- H.pylori is a bacterium linked to the development of peptic ulcers, affecting 90% of small intestines and 60% of stomachs in infected individuals.
- NSAID usage poses a 6X increased risk for developing ulcers, with 15-25% of dyspepsia patients experiencing PUD.
- Symptoms include epigastric pain (often related to food), dyspepsia, nausea/vomiting, loss of appetite, and melena (black tarry stools).
- Diagnosis typically involves upper endoscopy, and management may require antibiotics, antacids, or referral to a specialist.
- Most cases resolve, but there is potential for ulceration or gastric carcinoma.
Carbohydrate Malabsorption/Intolerance
- Condition results from inadequate digestion or absorption of carbohydrates, often due to missing intestinal enzymes.
- Symptoms include abdominal pain, bloating, watery stools, and excessive gas, often exacerbated by age or high carbohydrate diets.
- Diagnosis can involve a hydrogen breath test, where a significant rise in hydrogen levels indicates malabsorption.
- Management focuses on dietary modifications and patient education, with congenital enzyme deficiencies progressing over time.
Small Intestine Bacterial Overgrowth (SIBO)
- Characterized by excessive bacteria in the small intestine, with a prevalence of about 15% in the general population, escalating to 40% in IBS patients.
- Symptoms can vary, including abdominal pain, bloating, diarrhea, or constipation.
- Diagnosis may include breath tests, indicating SIBO through an increase in hydrogen after specific carbohydrate ingestion.
- Management may involve antibiotic treatment, and if untreated, chronic SIBO can lead to severe complications like malnutrition and intestinal failure.
Crohn's Disease
- A chronic inflammatory condition affecting the gastrointestinal tract, prevalent in 0.35% of the Canadian population, typically diagnosed in individuals aged 20-40.
- Genetic factors (like NOD2/CARD15 mutations) and risk factors such as smoking and NSAID use can heighten susceptibility.
- Symptoms include diarrhea, abdominal pain, weight loss, and fatigue, along with extraintestinal manifestations like anemia and osteoporosis.
- Diagnosed through ileocolonoscopy with biopsy and cross-sectional imaging; management often involves specialist referral and monitoring.
- Increased risk for various cancers and other health complications if left untreated.
Bile Acid Malabsorption
- Diarrhea resulting from excess bile acid production or malabsorption in the terminal ileum.
- Conditions like Crohn's disease, pancreas insufficiency, or post-cholecystectomy can contribute to this issue.
- Symptoms encompass persistent diarrhea, increased stool urgency, flatulence, and abdominal pain.
- Diagnosis can be made through SeHCAT testing or serum assays; treatment may require bile acid sequestrants.
Clostridioides Difficile-Associated Diarrhea
- Associated with infections from bacteria, commonly linked to antibiotic use and often occurring in healthcare settings.
- Symptoms range from mild diarrhea to severe colitis, with potential complications such as significant dehydration or fever.
- Diagnosis typically involves a history of recent antibiotic use and specific serologic tests.
- Management includes hydration support and discontinuation of the antibiotic if possible, with a recurrence rate of 13-50%.
Celiac Disease
- An autoimmune condition triggered by gluten in genetically predisposed individuals, affecting about 1% of Canadians, especially females.
- Symptoms can be diverse, including gastrointestinal distress and malnutrition-related deficiencies.
- Diagnosis relies on serologic testing for specific antibodies and small bowel biopsy.
- Strict gluten avoidance is crucial for management, with a risk for increased cancers and nutrient deficiencies if untreated.
Non-Celiac Gluten Sensitivity
- Occurs in the absence of celiac disease but demonstrates gluten-related symptoms in about 0.5-13% of the population.
- Symptoms include bloating, abdominal discomfort, fatigue, and other non-intestinal complaints.
- Diagnosis often utilizes a gluten challenge, while treatment focuses on dietary avoidance and patient education.
Disordered Eating

- Encouragement for seeking help, with resources like the National Eating Disorder Information Centre available for support.
GERD and Related Conditions
- GERD (Gastroesophageal Reflux Disease) characterized by heartburn, sour taste, dysphagia; symptoms include chronic cough, nausea, sore throat, and hoarseness.

- Diagnosis via breath tests reflecting a rise in breath hydrogen concentration after carb ingestion.
- Management may require antibiotic treatment or referral to a physician.
- Prognosis: Untreated SIBO can lead to severe complications like weight loss, malnutrition, and recurrence rates up to 44%.
Crohn's Disease
- Chronic inflammation affecting the gastrointestinal tract, potentially leading to extraintestinal complications.
- Prevalence in the Canadian population is 0.35%, typically diagnosed between ages 20-40.
