Symptoms

Signs and symptoms of SIBO often include:

• Loss of appetite
• Abdominal pain
• Nausea
• Bloating
• An uncomfortable feeling of fullness after eating
• Diarrhea
• Unintentional weight loss
• Malnutrition

When to see a doctor

Bloating, nausea and diarrhea are signs and symptoms of many intestinal problems. See your doctor for a full evaluation — especially if you've had abdominal surgery — if you have:

• Persistent diarrhea
• Rapid, unintentional weight loss
• Abdominal pain lasting more than a few days

If you have severe abdominal pain, seek immediate medical care.
