I wonder if the is adevice that you could carry in your pocket for example to tell us when it detects LG. That way us that do not smell it could take a walk outside or elswhere.There are plenty of pocket gas detectors for many types of gas, just wondering which type might work for us.

Well assuming the leaky gas is actually colonic gases the major smelly parts of that gas is hydrogen sulfide and things like mercaptans.I do some work with gas detection for other things and real-time devices (assuming you want to pay fairly big bucks for something that really does work, which if you want something small enough you aren't obvious may run to several hundreds if not several thousand dollars) can detect gases, but there is usually a trade off with rapid analysis in real time and accuracy. That is you can tell if it is there more than at what amount.The more different gasses you want to detect, the more expensive the machine will be. You also need to find out if you would need to hook the device up to a computer or if you can direct read the device.You would also need to know the sensitivity of the device http://www.professionalequipment.com/xq/AS.../qx/default.htm has quite a few. Some of these may be more set up for the "can it detect lethal amounts" rather than "can it detect any amount" and some gases are very smelly at very low concentrations that aren't near the lethal limit and most of the cheaper detection devices I would guess are more set up for lethal levels not smelly levels (as most are usually used to make sure sewer workers and such don't die when they enter an enclosed space that might have lethal levels of gasses), so might not work for the do I smell question answering, assuming H2S gas is what is the smell. Devices that do both H2S and mercaptans will probably be more expensive, but I didn't do a search for doing both as the H2S ones are fairly common. I'm not sure if we know which gasses are making the smell of the LGers and that they can't smell it may indicate that at least some of the smell may be in the breath rather than just leaking out the back end. To deaden the nose to the smell you usually need a fairly constant exposure to the odor.K.

You are on the right track about getting the "LG" analyzed.Measuring the gases is outside the scope of clinical gastroenterology and requires assistance of an academic scientist who studies gas in the body.Your best bet would be to aggresively pursue a doctor capable of making such a measurement. I know of three who have that capabilityDr. Michael Levitt at the Minneapolis VA Medical Centerhttp://www1.va.gov/directory/guide/facilit...&dnum=ALL&map=1Dr. George Pretihttp://www.monell.org/Faculty/preti.htmDr. Juan-Ramón Malageladahttp://www.vhebron.es/hg/adigestiu/cindex2.htm
