SIBO (Small Intestinal Bacterial Overgrowth)

Overview

SIBO occurs when there is an abnormal increase in the overall bacterial population in the small intestine, particularly types not normally found there. The excess bacteria interfere with normal digestion and absorption, causing gas, bloating, diarrhea, and nutritional deficiencies. SIBO is often associated with other conditions like IBS, celiac disease, and conditions that affect gut motility. It is diagnosed with a breath test and treated with antibiotics and dietary changes.

Symptoms

Common Symptoms

• Bloating and abdominal distension (often severe)
• Excessive gas and belching
• Abdominal pain or cramping
• Diarrhea or alternating bowel habits
• Unintentional weight loss
• Fatigue
• Nutritional deficiencies (iron, B12, fat-soluble vitamins)
• Food intolerances, especially to carbohydrates

Diagnosis

Diagnosis typically involves clinical evaluation, medical history, blood tests, and appropriate imaging studies. A healthcare provider will assess symptoms, order relevant laboratory work, and may refer to a specialist for confirmation.

Treatments

Treatment depends on the underlying cause and severity. Options may include medication, lifestyle modifications (diet, exercise, stress management), and ongoing monitoring. Always work with a qualified healthcare provider to develop an appropriate treatment plan.
