What is SIBO?

SIBO (Small Intestinal Bacterial Overgrowth) is a condition in which excessive bacteria grow in the small intestine, an area that typically houses relatively few bacteria. This overgrowth can interfere with digestion, damage the intestinal lining, and lead to chronic gastrointestinal symptoms such as:

  • Bloating and abdominal distention
  • Excessive gas
  • Diarrhea or constipation (or alternating between both)
  • Cramping and discomfort
  • Fatigue
  • Nutrient deficiencies
At Elite Digestive Health, we specialize in identifying hard-to-diagnose GI conditions like SIBO using advanced, evidence-based diagnostics. Led by Dr. Benjamin Basseri, one of the most experienced GI doctors in Los Angeles for SIBO evaluation. We work to get to the root of your symptoms and create a personalized path toward lasting relief.

When You Should Consider SIBO Testing

SIBO can mimic other gastrointestinal conditions, making an expert diagnosis essential. Dr. Basseri is often referred to as the best GI doctor for abdominal pain in Los Angeles, thanks to his track record of getting patients real answers when other providers can’t.

You may want to be evaluated for SIBO if you:
Struggle with persistent bloating, especially after eating
Experience unexplained GI symptoms that don’t improve with diet changes
Have a known motility disorder or a history of abdominal surgery
Have been diagnosed with IBS but aren’t responding to traditional treatments
Live with autoimmune or inflammatory conditions (e.g., celiac, Crohn’s, diabetes)
Experience fatigue or unexplained nutrient deficiencies (like B12 or iron)

During

  • You’ll complete a SIBO breath test, which involves drinking a sugar solution and providing breath samples over 2-3 hours.

After

  • Results are interpreted by Dr. Basseri, one of the best GI specialists in Los Angeles for functional gut disorders.
  • If SIBO is confirmed, your treatment plan may include targeted antibiotics, dietary modifications, prokinetic agents, or follow-up testing.

How to Treat SIBO

Small intestinal bacterial overgrowth is typically treated with a targeted combination of antibiotics, dietary changes, and supportive therapies to restore balance and reduce symptoms.
  • Targeted antibiotics (such as rifaximin) to reduce bacterial overgrowth in the small intestine
  • Low FODMAP or elemental diet to minimize fermentable carbohydrates that feed bacteria
  • Prokinetic agents to improve gut motility and prevent recurrence
  • Nutritional support to address deficiencies caused by malabsorption
  • Breath testing follow-up to confirm eradication and monitor for relapse
