ARTICLE 13: Small Intestinal Bacterial Overgrowth (SIBO)
Overview
Small Intestinal Bacterial Overgrowth (SIBO), occurs when bacteria normally found in the large intestine begin to multiply in the small intestine. This interferes with digestion and nutrient absorption, often leading to chronic discomfort.
Practical Steps for Patients
-
Recognize symptoms: persistent bloating, abdominal pain, diarrhea or constipation, gas, and unexplained fatigue or weight loss.
-
Ask about testing: breath testing is the most common diagnostic method, measuring gases produced by bacteria.
-
Treatment approaches: physicians may prescribe specific antibiotics to rebalance gut bacteria. Nutrition plans such as a low-FODMAP diet may also help when guided by a professional.
-
When to seek urgent help: severe abdominal pain, dehydration, or rapid weight loss should be addressed promptly.
