They will be conducted on separate occasions and will be discussed with you at your first appointment.  \nWhat is a hydrogen/methane breath test?  \nA hydrogen/methane breath test (HMBT) is a simple non-invasive test which can test for conditions such as:  \n• small intestinal bacterial overgrowth (SIBO)  \n• lactose and fructose intolerance  \n• assessing bowel transit time.  \nThe test involves taking an initial sample of your breath and then drinking a sugary drink.  \nFollowing the drink we will then take further samples of your breath at regular intervals.  \nThe breath samples are fed into a machine which analyses the gases in your breath and the data will be recorded by a member of staff.  \nThis will be done for up to 3 hours to monitor the gas levels and once the test is complete you will be able to go home.  \nWhat are the risks?  \nThe test is very safe, however, it may trigger your usual symptoms that you have been referred for.  \nWhat are the alternatives?  \nIt is possible to do gene testing, blood glucose monitoring and biopsy via endoscopy.  \nHowever, these are not widely available and HMBT is the simplest, safest, least invasive and most readily available method of diagnosis.  \nWhere do I go?  \nBreath testing is currently performed on one of the wards away from our main GI Physiology department.  \nDetails of the clinic location are provided on your appointment letter.  \nPlease do not hesitate to call into or contact our main department if you have any problems locating this clinic.  \nCan I bring my children with me?  \nIt is not appropriate to bring children under the age of 16 into this area without appropriate adult supervision, whilst you undergo your test.  \nAdult supervision should be provided by someone other than you (the patient), as children will not be allowed to accompany you into the clinical rooms. Staff in the department are unable to care for your child/children.  \nGiven the length of these tests and the limited space in the waiting room, we advise you arrange childcare away from the hospital.  \nFailure to arrange appropriate childcare may result in the cancellation of your test.  \nIf this is likely to cause you significant difficulties, we kindly ask you to contact the department to arrange a more convenient appointment or discuss your needs.  \nWhat should I expect?  \nOn arrival you will be asked to take a seat in the small waiting area. Once the test is about to start you will be escorted to a separate clinical area.  \nFirstly, we will use a private area to discuss the test with you, ask about your symptoms and answer any questions you may have. You will then be taken into the breath test room where you will be sat with other people undergoing the same test.  \nThere will be toilet facilities close by and if at any point you need to discuss something privately, please ask a member of staff.  \nWe advise that you bring something to keep yourself occupied for the duration of the test, such as magazines or a ","cbCaikDu6kWyhXoM","https://ap.wps.com/l/cbCaikDu6kWyhXoM","pdf",270274,12,"English","# Hydrogen/methane breath test (HMBT)\n## What it is and what conditions it can assess\n## Risks and alternatives\n## Where to go and visiting guidance\n## What to expect on the day\n## Preparing for HMBT (instructions and medication timing)","[{\"question\":\"What is a hydrogen/methane breath test (HMBT) and how does it work?\",\"answer\":\"HMBT is a simple non-invasive test.
