Can sibo cause weight loss?

Seeing the scale drop constantly is so stressful and makes me worry about all sorts of extreme illnesses. SIBO is known to cause poor nutrient absorption, so please get a proper breath test done soon so you can start treating it.

Yes, if the bacteria are absorbing your food, you will lose weight and feel weak. A practical step is to eat simple, easily digestible meals like light khichdi or white rice, and consult a doctor for a proper antibiotic course.

Look, if your gut is full of bad bacteria, your body won't get any nutrition, so obviously you will lose weight. Stop searching online, go to a good gastroenterologist, get tested, and clear the infection first.

I am also losing weight rapidly because of my constant gut issues and it is making me so nervous. Has anyone else here experienced significant weight loss with SIBO, and did you manage to gain it back after treatment?

I lost almost 6 kgs in two months when my SIBO was at its peak because everything I ate triggered diarrhea. Once I finished my gut treatment and started a tailored diet, my weight finally stabilized.
