Small Intestinal Bacterial Overgrowth

Definition

Small Intestinal Bacterial Overgrowth is a condition where there is an abnormal increase in the overall bacterial population in the small intestine, particularly types of bacteria not commonly found there.

Scientific / Technical Definition

Small Intestinal Bacterial Overgrowth (SIBO) is a disorder characterized by an excessive growth of bacteria in the small intestine that disrupts the normal function and absorption of nutrients, often leading to symptoms like bloating, diarrhea, and malnutrition.

Benefits

• Relief of gastrointestinal symptoms once properly diagnosed and treated.
• Improvement in nutrient absorption after microbial balance is restored.

Examples

• Symptoms like bloating, diarrhea, and abdominal pain.
• Conditions linked to nutrient deficiencies due to malabsorption.

Additional Information

• Known issues: Diagnosing SIBO can be challenging because its symptoms overlap with other health conditions. Common diagnostic tests include breath tests evaluating hydrogen and methane levels.
