Study Notes

Short Bowel Syndrome (SBS)

Insufficient intestine length leads to malabsorption of nutrients
Severe dehydration and nutrient deficiencies can occur after surgery
Electrolyte and vitamin levels (B12) need monitoring.
High-calorie, nutrient-dense foods are necessary
Medications may need adjustment based on nutrient absorption issues

Small Intestinal Bacterial Overgrowth (SIBO)

Excess bacteria in the small intestine disrupts digestion causing malabsorption
Can cause malnutrition, weight loss, and low albumin and B12 levels
Low-carb diets may help reduce symptoms
Certain antibiotics can alter gut flora and affect absorption

Calculations

Be able to calculate BMI and classifications
Be able to calculate IBW, %IBW, and convert pounds to kilograms
Be able to calculate % weight change and classifications
Be able to calculate the Penn State Formula using kilograms and centimeters
Convert pounds to kilograms (1 kg = 2.2 lb)
Convert inches to centimeters (1 inch = 2.54 centimeters)
BMI = (Weight in kg) / (Height in meters)^2

Upper and Lower GI Tract Anatomy

Sphincters are circular muscles regulating content flow through the GI tract
Key sphincters include - Upper Esophageal Sphincter (UES), Lower Esophageal Sphincter (LES), Pyloric Sphincter, Ileocecal Valve, and Anal Sphincters
Sphincters prevent backflow and control the movement of food and waste

Digestion

Mechanical and chemical digestion starts in the mouth
Ileum is the site of B12 absorption
Malabsorption conditions like Celiac Disease and IBD can lead to issues like steatorrhea (fat in stool)

Medications with Food/Nutrient Interactions

Mesalamine (Asacol): used for IBD, may interact with nutrients
Corticosteroids: can increase appetite and affect glucose levels
Methotrexate: folate antagonist, may require folate supplementation
Common micronutrient deficiencies: Vitamin K, B12, Iron, Vitamin D, and Zinc

Medications that Alter Liver Enzymes

Acetaminophen: overuse can lead to liver damage
Statins: used for cholesterol management and can elevate liver enzymes
Antiepileptics: Phenytoin and carbamazepine can affect liver function
Antibiotics (e.g., tetracycline): can bind with calcium in dairy products
Warfarin: interacts with vitamin K-rich foods affecting blood clotting
Proton Pump Inhibitors (e.g., omeprazole): can hinder absorption of nutrients like vitamin B12 and iron

Lab Abnormalities

Dehydration leads to elevated creatinine and electrolyte imbalances
Metabolic stress can cause changes in glucose and electrolyte levels
Medication effects can alter liver enzymes or kidney function, impacting lab results

Mean Arterial Pressure (MAP)

Used to assess perfusion
A MAP of 65 mmHg or higher is generally considered adequate for organ perfusion

Enteral Nutrition (EN)

Initiated after hemodynamic stability is achieved, usually when a patient can tolerate oral intake.

Lower GI

Peptic Ulcer Disease (PUD): can be caused by H. pylori, NSAIDs, and stress
Nutrition for PUD focuses on avoiding irritants and promoting healing
Gastrectomy (stomach removal) complications include malabsorption and nutrient deficiencies
Supplementation with vitamins B12, iron, and calcium may be necessary after gastrectomy
Two types of diarrhea: Osmotic (resolves with fasting) and Secretory (does not resolve with fasting)
Nutritional consequences of diarrhea include dehydration and malnutrition
Common causes of malabsorption include celiac disease and IBS
Low-fat diets should avoid high-fat foods like butter and oils
Celiac disease symptoms include diarrhea and weight loss
Avoid gluten-containing foods (wheat, barley, rye)
IBS symptoms include abdominal pain and bloating
FODMAP diet restricts fermentable carbohydrates
FODMAPs are Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols
FODMAP foods to avoid: Wheat, garlic, onions, dairy, certain fruits (like apples and pears), and sugar alcohols (like sorbitol)

Crohn's Disease

Symptoms include diarrhea, nausea, vomiting, and cobble-stoning effect on the gut
Can lead to low albumin, electrolyte imbalances, malabsorption, malnutrition and dehydration
May need parenteral nutrition (PN) then enteral nutrition (EN)
Mesalamine (Asacol): may need an artificial sweetener in steroid form as an alternative

Irritable Bowel Syndrome (IBS)

Motility disorder causing constipation, diarrhea, or a mix of both
Electrolyte imbalances are possible
Following a FODMAP diet helps manage the condition
FODMAP foods to avoid: Wheat, garlic, onions, dairy, certain fruits (like apples and pears), and sugar alcohols (like sorbitol)
