the causes are generally from changes in stomach acid, changes in intestinal transit function, disruption of normal antibacterial defense mechanisms, medications, surgeries, and several others. The treatment is based on antibiotic therapy such as rifaximin or metronidazole

Thank you. I had no idea there could be those different causes. I will ask my doctor to investigate which was my cause and which antibiotic to take. Is this something that can be cured or might it come back after a course of antibiotic?

Generally, most people will require multiple rounds of antibiotic therapy.

I see. Does this antibiotic kill all the bacteria in the small intestine and leave the good bacteria in the colon?I read about a Blood test called IBSDetex at Quest that detects food poisoning as cause of IBS and SIBO, making SIBO an autoimmune disease. I did have severe food poisoning a number of years ago. Have you heard of this?

I have never heard of this test. You may want to ask your doctor about it prior to ordering it to see if he or she will be able to interpret the results.

I would ask him to order it. In California we can’t order our own tests without a physician.

I would try the antibiotics first to see if that helps.
