Gastrointestinal Health: Inflammatory bowel disease (IBD) Flashcards
Question: What is Inflammatory Bowel Disease (IBD), and what are the principal types?
Answer: IBD is a group of autoimmune conditions affecting the colon and small intestine. The two main types are Crohn’s Disease (CD) and Ulcerative Colitis (UC).
Question: What are the key symptoms of IBD?
Answer: Key symptoms include abdominal pain, diarrhea, urgency to pass stools, rectal bleeding (more in UC), weight loss, and fatigue from blood loss and malabsorption.
Question: What are the key complications associated with IBD?
Answer: Complications include colorectal cancer, osteoporosis, and anemia (iron, folate, and B12 deficiencies).
Question: What are the key characteristics of Crohn’s Disease?
Answer: Crohn’s disease can affect any part of the GIT, mainly the terminal ileum, with skip lesions and affects all layers (transmural). Symptoms include crampy right abdominal pain, loose semi-solid stools, and complications like fistulas and B12 deficiency.
Question: What are the key characteristics of Ulcerative Colitis?
Answer: Ulcerative Colitis affects the colon and rectum, with continuous lesions affecting only the mucosal layer. Symptoms include left-sided abdominal pain, bloody diarrhea, and complications like hemorrhage leading to anemia.
Question: What factors contribute to IBD development?
Answer: IBD involves a combination of genetic susceptibility, luminal microbial antigens, and environmental triggers leading to an autoimmune response that damages the mucosal lining of the GIT.
Question: What bacterial patterns are commonly seen in IBD?
Answer: Common bacterial patterns include very low or missing Akkermansia spp., raised R. gnavus and R. torques, increased gram-negative bacteria (Fusobacterium nucleatum), and decreased SCFA-producers like F. prausnitzii.
Question: What environmental factors can trigger IBD?
Answer: Triggers include antibiotics, NSAIDs, oral contraceptives, smoking (especially CD), stress, infections, poor diet (low fiber, high refined sugars, and food additives like carrageenan).
Question: What are some dietary strategies for managing IBD?
Answer: Strategies include removing inflammatory foods (e.g., dairy, gluten), considering low reactive diets (SCD, low FODMAP), consuming well-cooked foods, optimizing the omega-3 to 6 ratio, and including fresh green juices.
Question: What are some natural approaches to managing IBD?
Answer: Natural approaches include using vitamin D to stabilize tight junctions, fish oils for anti-inflammatory effects, and supporting the mucosal barrier with demulcent herbs like marshmallow root and slippery elm.
Question: What other supplements or natural agents can help with IBD?
Answer: Agents like ginger (inhibits LOX and COX), turmeric (inhibits COX-2 and NF-kB), aloe vera (supports wound healing), boswellia (inhibits 5-LOX), and Lion’s Mane mushroom (promotes intestinal mucosa regeneration).
Question: How can probiotics and prebiotics support IBD?
Answer: Probiotics like Lactobacilli and Bifidobacteria strengthen the epithelial barrier, while prebiotics like FOS and psyllium help produce SCFAs, such as butyrate, to support gut health.
Question: Which nutrient deficiencies are common in IBD cases?
Answer: Common deficiencies include vitamin B12 (especially in CD), folate, iron, zinc, calcium, potassium, magnesium, and fat-soluble vitamins (A, D, E, K).
