I just came back from taking the Bacterial Overgrowth test at UNC - it came back negative. THe test consisted of fasting from midnight until the test. The test took 2 hours. At 8:30 I blew into a bag to test my 'hydrogen level' - then I drank sucrose water. Every 15 minutes after that, I blew into a bag until 10:30. At that point the technician told me I do not have bacterial overgrowth. My baseline number (at 8:30) was 9 and it went down to 2 by 10:30.I wanted to have the test done - as I am IBS-d with severe pain 7/24 and hypomania (falling asleep at the drop of a hat) unless I take an antidepressant (Remeron). My severe symptoms showed up after this chain events: several apparent food poisonings, my first and horrible yeast infection, a miscarriage, 3 sinus infections - then about 3 weeks later, the pain and urgent diarrhea hit the scene.It is clear to me I have had IBS a long time but thought it was nothing or just lactose intolerance or celiac disease etc.I tellyou all these details not to bore you but for history - I will be happy to answer any other questions or add anything that I may have forgotten about the tes.

I am not sure what you mean - I was diagnosed at UNC by a gastro after being tested for celiac, having an endoscopy, a colonscopy and a small bowel xray. I was daignosed also with Post Partum Depression from my first son (4 years ago ) and again after the miscarriage

Thanks for sharing your experience!! I am thinking about having this test done. I figure it couldn't hurt anything, maybe by some miracle they can find something out and make me feel better.Kim

srhackett, Pardon my poor memory, but did we already discuss the yeast issue and possible Candida over-growth? Seems like we may have. If you haven't been treated with an oral antifungal and low sugar/no fermented/age food diet, I highly recommend it. My symptoms subsided gradually within a few months of being on this regimine. I still have to adhere pretty well to it or my symptoms come back, but it is much better, and I can tolerate small amounts of fruit and dairy now, which seem to be my worst sugar offenders. I hope you feel better soon. M.

COuple of additional points. This test only detects bacterial overgrowth of the small intestine. ALso, you must be antibiotic free for 2 weeks prior to the test. I take a probiotic every day and it does not affect the test results.I am going to go to the GP to get checked for strep or something as I am the one with the crypts on my tonsils if I don't take acidophoulus.I think my pain is brain/gut related in the sense that the psychosomatic element is there - I see now hoow much of an anixety filled person I have been all my life - and didn't recognize it.

This conclusion is not entirely valid because you just may not have many H2 producing bacteria.

Are you sure it was sucrose?

What other kinds are there? I hope to return to finishing up my editorial on this subject soon.------------------I am not a doctor, nor do I work for profit in the medical/pharmacological field, but I have read scientific and medical texts, and have access to numerous sources of medical information that are not readily available to others. One should always consult a medical professional regarding advice received.

Just a thought.The doctor who adminstered the lactulose hydrogen breath test said it is good to contact the lab, or whoever, giving the test a week or so before going for the appointment. Just leave a message asking them to confirm that you are taking the NEW bacterial overgrowth, LactUlose hydrogen breath test. The doctor said different sugars are administered for different breath tests. Just make sure communication is clear if you, as a patient, would just like the new test. Sometimes due to unintended miscommunication, patients can end up with a similar test but not the one they wanted. If you let them know ahead of time, they can check with the doctor, check the chart, and have the right preparation ready.I did call about two weeks ahead just to confirm the exact test I would have.

Lactulose IS NOT a new hydrogen breath test.The data in the medical literature indicates that Lactulose tests are not specific for BO. Lots of problems with false negatives (meaning you don't have it but the test says you do.) The specificity problems with this test is one of the reasons the UNC clinic doesn't use the test. The Laculose Breath Test has been around since the 1980. The first mention in the medical literature is 1979.The only NEW thing about it is the study looking at SIBO in IBS patients.K.------------------I have no financial, academic, or any other stake in any commercial product mentioned by me.My story and what worked for me in greatly easing my IBS: http://www.ibsgroup.org/ubb/Forum17/HTML/000015.html [This message has been edited by kmottus (edited 05-08-2001).][This message has been edited by kmottus (edited 05-08-2001).]

I can't help thinking these breath tests for SIBO are causing more emotional/mental distress to IBS sufferers that necessary.If they aren't all that accurate - wouldn't it be sensible to automatically test for SIBO by carrying out an upper endoscopy?I know that creates a few mintues of discomfort for the patient - but I'm sure K mentioned that this is the most accurate way to test for SIBO - and the GI and patient would know from the initial procedure what they were dealing with in the first place....instead of dangling real or imaginary carrots in front of them.I was pretty lucky to have already been scheduled for a Celiac's biopsy of my Small Intestine so I asked my GI doc to test for BO at the same time - and it was then all over - and I know I don't have SIBO.Perhaps its just medical politics - just seems the medical profession has its ways of slowly torturing patients to death by the old dangled carrot trick.Clair

Doctors are always trying to find ways to figure things out without having to do something invasive. Alot can be done to make the hydrogen breath tests better, like which sugar you use and how you interpret the data, but in the end it has the same types of problems that are typical of all indirect tests.It's like the blood tests for H.pylori and Celiac. These are indirect compared to taking a biopsy, and while they work much of the time, they miss somethings and don't catch others. However, they seem to have much better track records than the lactulose hydrogen breath test.SIBO is something that doctors have known about and tested for, but generally it isn't a big issue for most people with IBS symptoms, but for some small percentage it is. However, the symptoms of SIBO are well known so it should be fairly easy for a GI specialist to figure out which IBSers might need the tests, however when faced with desparate patients with a disorder that doesn't have alot of treatment options I fear that lots of people will be getting false positive lactulose tests and taking un-necessary antibiotics. Or doctors who will give it a go without even a test.K.------------------I have no financial, academic, or any other stake in any commercial product mentioned by me.My story and what worked for me in greatly easing my IBS: http://www.ibsgroup.org/ubb/Forum17/HTML/000015.html

KMottus was absolutely right that this is a test that has been around for years. This use of it is just fairly new, per my doctor, to many gastroenterologists. Sorry for the confusion.
