Small Intestinal Bacterial Overgrowth (SIBO) is a medical condition where excessive bacteria grow in the small intestine, which is not typically associated with high bacterial counts. This overgrowth can interfere with normal digestion and absorption of food, and it can cause various symptoms.
Causes
SIBO is usually caused by an underlying condition that affects the normal motility of the small intestine, such as:
- IBS
- Celiac disease
- Crohn's disease
- Gastric bypass surgery
- Medications that affect gut motility
Symptoms
Common symptoms of SIBO include:
- Abdominal pain
- Bloating and gas
- Diarrhea
- Malabsorption leading to deficiencies in nutrients
- Weight loss
Diagnosis
Diagnosis typically involves a breath test, which measures the production of hydrogen and methane after consuming a sugar solution.
Treatment
Treatment options include:
- Antibiotics to reduce bacterial overgrowth
- Dietary changes
- Probiotics
- Treating underlying conditions
Prevention
Preventive measures focus on managing underlying conditions and dietary modifications to reduce symptoms and prevent recurrence.
