The short answer is no. SIBO, or Small Intestinal Bacterial Overgrowth, happens when the bacteria that normally live in your gut get out of balance and grow too much in your small intestine. This can cause uncomfortable gastrointestinal symptoms like bloating, diarrhea, and stomach pain. But SIBO isn't caused by an infection you can catch from someone else. Instead, it's usually triggered by internal problems with how your digestive system works. If you think you might have SIBO, talk to your doctor. They can help figure out what's causing your symptoms and create a personalized plan to help you feel better.
