Study Notes
Irritable Bowel Syndrome (IBS)
- IBS is a chronic gastrointestinal disorder, characterized by recurrent abdominal pain and changes in bowel habits (diarrhea, constipation, or both).
- It's considered a gut-brain interaction disorder.
- The exact cause isn't fully understood, but multiple factors contribute.
Most Likely Cause
- Altered gut microbiota: Imbalances in intestinal microbes can cause symptoms.
- Brain-gut axis alterations: Disruptions in communication between the central and enteric nervous systems affect gut motility and sensitivity.
- Dietary factors: Fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) may trigger symptoms.
- Medications like antibiotics can alter gut microbiota and cause symptoms.
- Low-grade gut inflammation: Chronic, mild gut inflammation may develop IBS.
Pathophysiology
- IBS involves a combination of:
- Visceral hypersensitivity: Patients experience heightened sensitivity to normal gut stimuli, resulting in exaggerated pain signals.
- Altered motility: Increased or decreased intestinal motility causes diarrhea (IBS-D), constipation (IBS-C), or both (IBS-M).
- Altered microbiota: Imbalances can affect bowel habits, gas production, and immune response.
- Brain-gut axis dysfunction: Problems with communication between the brain and the enteric nervous system impact gut motility, secretion, and perception of pain.
Disease Transmission
- IBS is a non-infectious disease, not transmissible from person to person.
- While gastrointestinal infections can trigger IBS, this is not considered transmission.
Risk Factors
- Modifiable: Dietary factors (high-FODMAP foods), medications (e.g., antibiotics), stress, anxiety, history of infections, lifestyle (sedentary habits).
- Non-modifiable: Age (young adults), gender (female), genetics, early life stressors, history of gastrointestinal infections.
