hey folksi knew that some people with fructose malabsorption/intolerance reported smell's problems, i searched the net and found that the symptoms and troubling foods(wheat,leeks,lettuce,Sorbitol ,corn syrup....etc)of fructose malabsorption are very suggestive to be the cause of FBO unlike TMAU that is extremely rare or candida which is totally a myth ,any one has been tested for fructose intolerance?i would like to be checked but unfortunately i don't think that "hydrogen breath test" is present in iraq. :( http://en.wikipedia....e_malabsorptionbtw/the 4-6 months of candida diet equals the time needed for a fructose free diet(so the fructase enzyme be regenerated in the intestine in the case of secondary fructose intolerance)Al barzenji/baghdad.

Undigested carbohydrates usually aren't a big contributor to the odor of the gas. They are usually broken down into Hydrogen (why the breath test works) CO2 and Methane. None of those have an odor.The odors in gases usually comes from sulfur and that is found in high protein foods and some veggies (like onions and garlic). If you have sulfur reducing bacteria and sulfur that gets to the colon will be made into Hydrogen Sulfide or other gases that are very stinky at very small amounts. Usually people either have a lot of the sulfur reducing bacteria or a lot of the methane generating bacteria but not both at the same time, and some people have neither.Now sometimes a large volume of odorless gas can help carry those small amounts of stinky gas along, so that could effect odor transport from inside to outside.However things that normally deodorize the intestinal gas do not seem to work at all for many of those who suffer from FBO, which is why something like TMAU may be an explanation. Odors can come from a lot of different things. However some people do find that Pepto Bismol or other Bismuth compounds and those have been shown to bind sulfurous gases in the intestines of humans.

Thanks kathleenI based my suggestion on stories of some fructose intolerance patients,they do have foul body odour.and fructose intolerance may indirectly predispose to FBO,it's known that Fructose intolerance:-1-increase osmotic pressure in the intestine which drag water from body to intestine --->diarrhea--->decrease passage time for all dietary components--->high amount of undigested foods in colon--->a lot of gases--->bloating(formal),but instead of bloating our "FBO/Lg people" intestines pass the gases slowly and silently(says me!)2-damage bacterial floraif i remember well one of the sufferer was Australian guy on this board,and the other was American in another forum,if you read this please tell us whether fructose-free diet worked for you or not.

this is a medical lecture it confirm that malabsorption syndrome(fructose,lactose...) can lead to incontinence,I found even more interesting disorder it's called "pudendal nerve neuropathy" can occur due to chronic straining. the pic below prove that Lg/FBO is a known medical condition(minor fecal incontinence) ,we just need to find a good colorectal surgeon and not tell him "only at work/school" thing ,saying "always" is better.

Fecal incontinencePathophysiology and etiologyPartial incontinence ‚€“ loss of control to flatus and minor soiling Major incontinence ‚€“ frequent and regular deficiency in the ability to control stool of normal consistencyFour basic physiologic factors:1.stool consistency, 2.rectal compliance,3.rectal and anal sensation4.pelvic floor function can lead to a defective continencemechanismIncontinence with normal pelvic floorfunction:-1-Altered stool consistency‚€ĘInflammatory bowel disease‚€ĘInfectious diarrhea‚€ĘLaxative abuse‚€ĘRadiation enteritis‚€ĘShort bowel syndrome‚€ĘMalabsorption syndrome2-Inadequate rectal compliance ‚€ĘInflammatory boweldisease‚€ĘAbsent rectal reservoir (ileoanal, low ant. resection)‚€ĘRectal ischemia‚€ĘCollagen vascular disease (scleroderma, amyloidosis, dermatomyositis)‚€ĘRectal neoplasms3-Inadequate rectal sensation‚€ĘDementia, CVA, MS, brain or spinal cord injury/neoplasm, sensoryneuropathy, tabes dorsalis ‚€ĘOverflow incontinence:-Fecal impaction ‚€“ leading cause of incontinence in institutionalizedelderly patients‚€ĘDiabetes ‚€“ multifactorial, impaired rectal sensation is importantIncontinence with abnormal pelvic floorfunctionAnatomic sphincter defect ‚€“ internal or externalTraumaticObstetric injury ‚€“ prolonged difficult labor with forceps application,episiotomy complications, third or fourth-degree lacerationsAnorectal surgery ‚€“ anal fistula surgery - most common operativeprocedure that results in fecal incontinence; hemorrhoidectomyPelvic floor denervation ‚€“ degenerative neurogenicfactors are a common cause of non-surgically relatedincontinence1-Primary (idiopathic neurogenic incontinence)a-Pudendal neuropathy ‚€“ 80%. Denervation of the puborectalis muscle andexternal anal sphincter muscles ‚€“ results in an impaired ability tomaintain the anorectal angle and prevent gross incontinenceb-‚€œDescending perineal syndrome‚€Ě‚€“ results from constant strainingduring defecation that causes a traction neuropathy of the nervesrunning along the pelvic floor muscles. Both the puborectalis andexternal anal sphincter muscles become denervatedc-Vaginal deliveries2-Secondary:-1.Injuries to spinal cord, cauda equina2.Diabetic neuropathyCongenital abnornmalities:-‚€ĘSpina bifida‚€ĘMyelomeningoceleMiscellaneous

  • Rectal prolapse ‚€“ 60-70% incontinence.
  • Aging ‚€“ anal canalpressure and rectal compliance are decreased
  • Diagnostic evaluation
TreatmentImproving stool consistency:-Increase intake of bulking agents ‚€“ bran, psylliumAntidiarrheal agents ‚€“ loperamide, lomotil, cholestyramineBowel management:-‚€ĘFecal disimpaction‚€ĘScheduled toileting‚€ĘGlycerin suppositories daily, 30 min postprandial‚€ĘAttempt to defecate at the same time daily‚€ĘDaily tap water enemaBiofeedback therapyPatients looks at a polygraph tracing while attempting to contract theexternal anal sphincterThrough visual ‚€œfeedback‚€Ě of looking at anal canal pressures duringcontraction and verbal guidance, patients can learn to appropriatelycontract the external sphincter in response to the sensation of rectaldistension70% restoring continence 90% reduction in incontinent episodesSurgery....................

Ever since I read about Descending Perineum Syndrome, I've been wondering if I might have that. I didn't know neuropathy might also be involved, but that might also make sense, since I never feel the fecal smelling gas leaking, but I certainly smell it.I had a defecography to rule out Descending Perineum Syndrome, but all I don't know what the doc whether the doc was looking for DPS or nor, he might've just been looking into prolapses.I do have a history of long and hard straining. Sometimes I sat on the toilet for an hour and a half, and evdnlater I discovered that I didn't have anything to pass even though I definitely felt there was something left in there.A good find there, thanks ProudLgaser.

if you have DPS you would notice it ,one of the main complaint of the patient of DPS is deformity look at figuresin this book:-http://books.google....9...ome&f=falselook at what I've found in a memory-aid ,i extracted it from a medical site

Causes of idiopathic fecal incontinence7(D)s1-descent:-perineal descent,rectal prolapse,prolapsed haemorrhoid. 2-destruction:-malignant tumors&irradiation3-debility:-illness&old age4-deficiency:-congenital abnormality5-damage:-wounds,child birth,surgical procedures6-denervation:-spinal injuries,neurological procedure &spina bifida7-dementia:-senility & psychological problems8-pudendal nerve neuropathy:-result from chronic straining,perineal descent and attraction injuries to the nerve.

I don't have prolapsed haemorrhoid as you do ,but fixing that might help you(excluding the complications of the operation),i believe that Lg/FBO is of multiple causes(single disease can't explain it).

If LG is just a form of minor incontinence, then it would explain why staying away from caffeine has lessened symptoms for a lot of people. (many incontinence websites talk about avoiding caffeine)Also I've tried the fructose intolerance diet before. It reduces gas- but most fruits are a culprit from the sorbitol anyways. Kathleen's advice works, you just might have to tweak it for yourself by subtracting some known triggers that are individual to you and taking supplements. For me I also take digestive enzymes, fish oil, inulin, and eat probiotic yogurt. I avoid gluten, red meat, eggs, and high amounts of other dairy.I also take St. John's Wort to help me with depression issues, which is an indirect symptom of LG.This might sounds like educated quackery, but it has changed my life so much for the better.
