SIBO (Small Intestinal Bacterial Overgrowth) is a condition in which there is an abnormal increase in bacteria in the small intestine, leading to symptoms such as bloating, abdominal pain, diarrhea, gas, and even nutritional deficiencies. Diagnosis and treatment should be performed by a gastroenterologist, but some practical changes to your routine can help manage symptoms and improve your quality of life.
What is SIBO and why does it happen?
SIBO occurs when bowel movements slow down or anatomical changes occur, allowing bacteria that normally live elsewhere in the digestive tract to multiply in the small intestine. This can be caused by surgery, diseases such as diabetes, prolonged use of certain medications, or intestinal motility disorders.
Most common symptoms of SIBO
The most common symptoms include abdominal distension and pain, diarrhea or constipation, excessive gas, a bloated stomach, and, in more severe cases, weight loss and signs of malnutrition. Some people may also experience vitamin deficiencies, especially B12 and D, due to poor nutrient absorption.
Practical tips for everyday life
Adopt a Low FODMAP diet
Temporarily reduce foods rich in fermentable carbohydrates, such as onions, garlic, apples, and dairy products, to relieve symptoms and reduce intestinal fermentation.
Choose small, frequent meals
Avoid large amounts of food at once. Smaller meals aid digestion and prevent abdominal discomfort.
Manage stress and exercise
Emotional balance and moderate exercise help keep your gut healthy and prevent relapses.
Supplementation and medical monitoring
Because SIBO can cause nutrient deficiencies, it's important to have regular checkups and, if necessary, take vitamin and mineral supplements under medical supervision.
Specialized monitoring is essential to avoid complications and adjust treatment, which may include antibiotics, probiotics, or other medications.
Lifestyle and relapse prevention
Managing stress, engaging in regular physical activity, and maintaining a balanced diet can help regulate bowel function and prevent SIBO from returning. In some cases, the disorder can recur, so continued attention to symptoms and medical follow-up are essential.
With small dietary changes, attention to symptoms, and professional monitoring, it's possible to control SIBO and improve your quality of life. Early diagnosis and appropriate treatment are key to avoiding complications and ensuring well-being.
