Understanding Small Intestinal Bacterial Overgrowth (SIBO) 

什么是SIBO？ Small Intestinal Bacterial Overgrowth, or SIBO, occurs when bacteria normally found in the large intestine migrate to the small intestine and proliferate. This can disrupt the small intestine’s ability to digest food and absorb nutrients, potentially leading to further health complications such as a leaky gut, where harmful substances enter the bloodstream, possibly triggering allergies or autoimmune diseases. 

Function of the Small Intestine The small intestine connects the stomach to the large intestine and plays a crucial role in digesting food and absorbing nutrients. It also supports the immune system, aided by beneficial bacteria. 

Causes of SIBO SIBO can arise when natural mechanisms that prevent large bowel contents from backflowing into the small intestine fail. Potential causes include: 

• Low Stomach Acid: Reduces the body’s ability to kill harmful bacteria. 
• Impaired Bowel Motility: Leads to insufficient clearing of the small intestine. 
• Structural Problems: Such as issues with the ileocecal valve between the large and small intestines. 
• Predisposing Conditions: Including IBS, Coeliac Disease, and Crohn’s Disease. 
• Antibiotic Use: May disrupt the normal gut flora. 

Symptoms of SIBO Common symptoms include: 

• Abdominal Pain and Discomfort 
• 胃胀气 
• Diarrhea or Constipation: Constipation is less common. 
• Excessive Gas and Burping 
• 疲劳 

Diagnosing SIBO The primary diagnostic tool for SIBO is a breath test that measures hydrogen or methane produced by bacteria in the intestine. This test can indicate bacterial overgrowth based on the gases produced during digestion. 

Managing and Treating SIBO Treatment should be guided by a healthcare professional and may include: 

• Medication: To address bacterial overgrowth. 
• Diet Adjustments: Incorporating high-fiber, plant-based foods and reducing intake of processed foods and sugars. 
• Lifestyle Changes: Regular exercise can improve overall digestive health. 

Dietary Recommendations 

• Increase Fiber Intake: Helps regulate bowel movements and supports gut health. 
• Choose Whole Grains: Over refined carbohydrates to maintain a healthier digestive system. 
• Limit Processed Foods and Sugars: To reduce potential triggers of SIBO. 
• Moderate Alcohol Consumption: As excessive intake can exacerbate symptoms. 

Seek Professional Advice Consulting with a healthcare provider is crucial for an accurate diagnosis and to tailor treatment to individual needs, particularly to distinguish SIBO from other digestive conditions.
