Diet counseling for irritable bowel syndrome (IBS) based on FODMAP elimination and stepwise reintroduction to reduce bloating, abdominal pain and irregular bowel habits.
Indication
- Adults diagnosed with IBS (irritable bowel syndrome) by a physician
- Individuals with recurrent abdominal pain, bloating and gas complaints
- Functional bowel disorders with frequent diarrhea or constipation episodes
- Patients whose digestive complaints worsen with specific foods
- Individuals seeking nutritional support in addition to standard IBS pharmacotherapy
- Cases in which FODMAP-containing foods are suspected as triggers
Preparation
- Bring previous laboratory results (blood, stool and, if available, colonoscopy report)
- Keep a food and symptom diary for at least 7 days before the appointment
- List all medications, supplements and probiotics you use
- Consult your physician if celiac disease and lactose intolerance tests have not yet been done
How it's performed
- A detailed nutritional history and complaint assessment is performed
- Anthropometric measurements (weight, height, waist circumference) and body composition analysis are taken
- Trigger foods, including those containing FODMAPs, are identified
- A low-FODMAP elimination plan is provided for the first 4-6 weeks
- Once symptoms decrease, foods are reintroduced one by one in a controlled manner
- A sustainable, balanced and individualized long-term diet plan is established
Post-procedure
- Follow-up visits are scheduled every 2 weeks during the first month
- Tolerance is recorded for each food group during the reintroduction phase
- Symptoms and their relationship with the diet are monitored using a symptom diary
- Periodic laboratory tests are recommended to prevent vitamin and mineral deficiencies
- Once stable, follow-up continues every 3-6 months
Risks
- Long-term restrictive diets may reduce gut microbiota diversity
- Insufficient fiber intake may worsen constipation
- Deficiencies of calcium, iron and B vitamins may develop
- Disordered eating tendencies may increase if applied without guidance
- Unnecessary permanent restrictions may occur if foods are not properly reintroduced
FAQ
Is the low-FODMAP diet meant to be followed for life?
No. The elimination phase usually lasts 4-6 weeks. Foods are then gradually reintroduced and a balanced long-term plan is built around what the person tolerates.
Do I need to stop my medications?
No. Nutritional therapy supports rather than replaces the treatment prescribed by your physician. Medication changes are made only on physician advice.
Should I take probiotics?
Certain probiotic strains may help some individuals, but the same product is not recommended for everyone. The decision should be individualized together with your dietitian and physician.
How long until my symptoms improve?
Most people notice a significant reduction within 2-4 weeks. Because the response is individual, progress is monitored with regular follow-up.
