Learn takeaways on the role of diet and nutrition for managing common gastrointestinal conditions that can overlap with IBD:
✅ The management of IBS is evolving from treating symptoms 👉 understanding causes and choosing the right treatment
👉 Common mimickers of IBS with diarrhea arise in the gut mucosa (e.g., IBD) or the intestinal lumen (e.g., bile acid malabsorption)
👉 Pelvic floor dysfunction affects 40% of people with chronic constipation
👉 Individuals with mast cell activation syndrome, postural orthostatic tachycardia syndrome, and hypermobility spectrum disorders 👉 ⬆ digestive and psychological burden
âś… Diets for managing IBS:
🟢 Well-studied diets: fiber-modified diet, traditional dietary advice/NICE guidelines, and the low FODMAP diet/’gentle’ FODMAP diet
đźź Less-studied diets: Mediterranean diet, low nickel diet, low histamine diet, and restrictive diets based on IBS-specific IgG testing
✅ Dietary advice for postural orthostatic tachycardia syndrome involves ⬆ sodium (3-10 g of salt/day) & fluid (2-3 liters per day) intake, and modify meal consistency and frequency
âś… Indigestion and a slow-empting stomach may coexist in the same person
👉 Dietary strategies should be tailored based on: patient history, symptom patterns, and tolerance
👉 Symptoms can be exacerbated by certain foods (e.g., fat-rich foods) ➕self-perceived food sensitivities
âś… Diet and nutrition tips and tricks in ostomies and short bowel syndrome:
