When Should Patients Receive a Hydrogen Breath Test (HBT)?
Anyone with chronic gas, bloating, cramps, diarrhea and /or constipation should have an HBT. In addition, SIBO is so common in CFS/FMS that all CFS/FMS patients should be tested at least 1 time. If normal testing is seen, we reassure. If SIBO is found, treat (see below) and recheck a month after the last day of treatment and whenever bowel symptoms recur. If the underlying causes are not treated, SIBO may recur every several months after the Rifaximin antibiotic is taken. HBT testing can also be done for lactose and fructose intolerance (each test is different) if SIBO is not found to explain symptoms. One of these tests can be done in any individual each day. So in 3 days SIBO, lactose and fructose intolerance can all be tested for.
