I was reading some old threads like "Tidbits about Gas" and it finally occured to me how stress could cause gas. I suppose I am right in saying stress affects motility. Well then if it increased motility in someone then that could cause undigested food to be moved along in the gastrointstinal tract and reach the colon where the bacteria feed off of it.

If it increased motility, it would cause diarrhea resulting in substrate and bacteria being excreted before the bacteria were finished with it, plus reducing the number of bacteria available to work on the incoming material. So no increase.

The paper went on to say if motility is sufficiently rapid, diarrhea may be produced.

I think if you get 8 high-amplitude peristaltic contractions in the colon a day you will get diarrhea (vs 3 for healthy controls). That is what has been found in some with IBS.

flux, I always learn so much from you. Maybe 5 high amplitude peristaltic contractions lead to gas then.

bonniei,I enjoy your many thoughtful questions but I am concerned over advice that Flux has been passing off to many individiuals on this forum. Flux acts as if he is a medical doctor passing off in many cases blatantly incorrect, deceiptive and dangerous information. Flux does not have the respect to the many members of this forum who have asked for his credentials, background or any basis for making his statements. Or what are his "unknown sources" of information he claims he has. Flux has diagnosed, prescribed therapies and criticized others to members of this forum and this is practicing medicine.I am not a doctor but I have worked in the medical profession for years and I am smart enough to only relay my personal experiences with IBS, not pretend I know something I do not. If I may make a suggestion, technical or medical questions can be answered by a licensed medical doctor through this forum at "Ask the Specialists" at http://www.ibsgroup.org/cgi-local/ubbcgi/u....cgi?category=5 I say this in the best of intentions that the members of this forum will have an opportunity to mutually discuss our experiences and receive competent advice.in health, greg...

Look I have said I will never defend flux or say anything bad about him so I don't want to get involved in this discussion.All I can say is I enjoy my discussions with him and I use what he says as a jumping off point that I do more research on. I do not treat him as a doc but when my docs fail me like they did recently he has always come through with info. I do not come to this board for support or help as such but to have discussions and I can tell you flux is the only one I can have discussions with in the gas forum. I do it to pass my time.

I am not a Dr. - but I have been plagued with such gas& bloating- but this laborday weekend- I ate Milk products- and things that normally would have given me great distress- but I was happy & so relaxed- I think the link is very strong between stress & gas- &: IBS symptoms.

Hi ibs2003 while the connection between stress and D and C is well established it is not that clear between gas and stress,. Very few papers have been written about it so I was excited to find this.

Hi guys!Well, I can only speak personally also. I know stress makes me very gassy...or perhaps it just sppeds it along when my tummy muscles get tense? I did a quick survey of family and they agreed that when the get nervous they too get gas.

This article may help:Gut reactions Treating the emotional componentof irritable bowel syndrome By JESSICA SEIGEL Gastroenterologist Susan Lucak treats IBS patients in tandem with a psychologist. A stomachache caused by emotional upset is so familiar that we've got an expression for it: getting "butterflies." But this was more like B-52s in Judy's gut. Until finding help that surprised even her, the fiftysomething interior decorator suffered bouts of stabbing abdominal pain and chronic diarrhea that made her miss work, cancel social visits, and stay home for fear she wouldn't get to a public bathroom in time. "I was just miserable," says Judy, who didn't want her full name used because of embarrassment about her condition. For 15 years, she went from gastroenterologist to gastroenterologist seeking relief, but repeated colonoscopies, endoscopies and related tests found no lesions, inflammation or other physical sign of disease. Doctors' advice to eat more fiber caused worse cramps and gas, but it was their comments that hurt the worst. "They looked at me like I was a mental case," she recalls, her voice tightening at the memory. "They said there was absolutely nothing wrong with me - that it was all in my head." Hurtful as they are, those words can also heal people like Judy, who was finally diagnosed with irritable bowel syndrome (IBS), a particularly vexing condition thought by many specialists to have an emotional component. Irritable bowel problems are the most frequent complaint brought to gastrointestinal (G.I.) specialists. Medical care for them costs $10 billion a year, according to the American Gastroenterological Association. Varying degrees of stomach troubles with no known physical cause are also second only to the common cold as a reason for missed work. The still-controversial diagnosis for ongoing, painful stomach troubles, which may include persistent diarrhea or constipation, usually comes after tests prove fruitless. But doctors, including G.I. specialists and researchers, sharply disagree over how emotions are involved in the illness. Also in dispute is the significance of university studies in the last 20 years that show psychotherapy is successful in reducing bowel symptoms and pain. The stomach doctors didn't help Judy. But she eventually found her way (after an Internet search) to Mary-Joan and Charles Gerson, a psychologist and gastroenterologist, respectively, who opened the Mind Body Digestive Center in Manhattan five years ago. Her gut troubles and pain largely disappeared after five "psycho-educational" group therapy sessions, plus individual meetings with the husband-and-wife team. "Something happened when I was talking about myself. Maybe it was unconscious. They say that when you talk about it, it gets better," says Judy, who attributes her recovery six months ago to experts who helped her see the role of anxiety in her flareups, but also validated the reality of her physical symptoms. "There's definitely an emotional connection," she says. Her story is no fluke. "This is the cutting edge of neuroscience," says Dr. Mary-Joan Gerson. "The literature clearly supports a psychological connection. We don't know exactly what that link is, but it exists." MEDICAL CONTROVERSY Though the exact nature of the link is poorly understood, a committee of gastroenterologists, psychiatrists and psychologists from the United States, Canada and England recently published IBS guidelines recommending that doctors include mental-health approaches in treating the disease. The panel's report cited a "significant superiority of psychological over conventional medical treatment" in 10 of 13 small-scale studies dating to the late 1980s. ("Routine" care ranged from anti-diarrheals or laxatives to nothing at all.) "Irritable bowel syndrome as a condition has defied good medical treatment," says gastroenterologist Douglas Drossman of the University of North Carolina at Chapel Hill. He leads the international IBS committee and is widely recognized for pioneering research on the syndrome's psychological role. "There is compelling evidence that cognitive treatment works. But it's not fully accepted yet. There may even be a stigma that this is a psychiatric problem." The stigma originates in older theories about psychosomatic illness, which suggested that unconscious conflicts and trauma can express themselves through physical symptoms. Today, researchers dismiss the notion of such direct cause and effect as simplistic, and instead use the term "bio-psychosocial" to describe the interplay of biology, genetics, thought, emotion and stressful events like divorce, unemployment and death of a loved one. Destigmatizing the illness - at least among medical doctors - is tricky, since studies show that 40% to 60% of IBS patients surveyed in specialized clinics also suffer from psychiatric conditions like anxiety disorder and depression. Female patients outnumber male ones by two to one, and as many as half of IBS patients in specialty care also report having been sexually or physically abused in childhood. UNITING MIND AND BODY But about half of IBS patients have no psychiatric disorders - except, perhaps, anxiety about often humiliating symptoms of an illness that can cause incontinence and flatulence. So what comes first - stress or the symptoms causing stress? This "vicious cycle," according to the latest view, involves a continuous feedback loop connecting the central nervous system and stomach. "It's not a nebulous notion of mind over body," says Susan Lucak, a gastroenterologist and medical professor who treats IBS patients in tandem with a psychologist at Columbia Presbyterian Hospital. "There are direct nerve connections from the gut to the brain." The gut contains 95% of the body's serotonin, the chemical that sends messages between nerves and also affects mood. Dubbed the body's "second brain," the gut somehow uses these neurotransmitters to digest and push food to the colon without requiring direct orders from the brain. That may be one reason low-dose anti-depressants decrease some irritable bowel troubles, particularly pain - and why emotions make the stomach act up. THERAPY IN ACTION Researchers don't know how it all works, but experiments using probes have shown that IBS patients are more sensitive to pain in the bowel. Brain images also reveal that stomach pain for IBS patients overactivates a part of the brain associated with anxiety. Imaging also shows that psychotherapy reduces activity in areas of the brain associated with worry, sadness and anxiety. "Many people don't understand that psychotherapy is active in the brain," explains psychiatry professor Sanjaya Saxena, co-author of imaging studies at the University of California at Los Angeles. But not all psychological strategies equally reduce pain and bowel symptoms, according to an analysis of 20 small-scale studies published in the June 2002 Journal of Consulting and Clinical Psychology. Treatments rated as effective were combinations of cognitive and behavioral therapy aimed at modifying negative thoughts and actions; psychodynamic therapy focused on personal "insight" and linking present and past experience, and hypnosis that creates a state of deep relaxation and suggestibility. On the other hand, biofeedback and peer-run support groups without a therapist had the same effect as no treatment. "The goal of most treatment programs is to cut episodes in half in terms of frequency and pain intensity," says Lisa Scharff, assistant professor of psychiatry at Harvard Medical School, who co-authored the review. "You can't change someone's anatomy, but you can help them change the way they respond to stress, which is the big trigger for an individual IBS episode." GETTING RESULTS In cognitive therapy - a treatment popular in the U.S. - patients learn to become aware of emotions before and during outbreaks through diaries and counseling. They then work on changing negative thinking that causes stress. In three widely cited but small-scale studies at the University at Albany, 55% to 80% of patients reported fewer symptoms after 10 sessions, compared with about 10% improvement in the untreated control group. "People surprise themselves when they actually slow down enough to see what they're thinking," says psychologist Edward Blanchard, director of the University at Albany's Center for Stress and Anxiety Disorders. Blanchard led the Albany studies and is completing a larger, two-university research project with 200 patients. Typical "negative" thoughts, like "I must always be perfect. If I'm not, no one will ever love me," he says, can change once patients realize how such irrational, "catastrophic" thinking causes the stress that leads to irritable bowel episodes. Blanchard, on the psychology end, and Drossman, in the medical camp, say their larger studies, to be published next year, may answer basic questions about which treatments work best for certain patients, and why they work. In the meantime, doctors such as Lucak at Columbia are designing combinations of therapy and drugs depending on the case. Patients with negative views about themselves may respond best to cognitive-behavioral therapy, she says. Those who feel stressed or mildly anxious may benefit from hypnotherapy, and those with difficult personal relationships may do well in psychodynamic therapy. Though many questions have yet to be answered, IBS experts say, adding psychological therapy to standard medical care cuts down or eliminates the need for drugs, which require continual use and often cause unhealthy side effects. Therapy also can protect against relapse in the long run. That's been the case for Kathleen Mottus, an environmental scientist whose debilitating symptoms have not returned in four years since she finished three months of cognitive therapy in a university research study. "I don't know exactly how the therapy worked," says Mottus, 39, who still has occasional but manageable outbreaks. I just know it did. It won't cure everybody - nothing does. But it can make a big difference."

Hi flowergirl -yes when we get stressed we do tense up our muscles and that could lead to releasing the gas which is already there but I was interested in how gas could actually be created by stress.yolo the article talks about diarrhea and constipation only and not gas. But stress can increase motility and by the methods I have suggested lead to more gas.

Since when are butterflies the same as a stomachache? We don't even know if butterflies are connected with the GI tract!
quote:y emotional upset is so familiar that we've got an expression for it: getting "butterflies." But this was more like B-52s in Judy's gut.
This is also wrong. It makes it sound as if there is some physical and abnormal motility event going on in the gut. The gut could even be sleeping when these supposed B-52s are dropping "bombs". It would be more accurate to call it screaming as if there were B-52s dropping bombs.

This wass originally posted by Talissa on another thread but it makes the point that stress can alter Microflora. So if it allows the residence of more gas producing bacteria or prevents the residence of the gas consuming bacteria, it could cause gas"HOW STRESS ALTERS INTESTINAL MICRO FLORA:�Along with other endogenous and exogenous factors which may interfere in the regulation of various pathways that control the intestinal microflora, physical and psychological stress seem to play a crucial role. ��In order to estimate the influence of psychological stress on the intestinal microflora composition, repeated restraint stress was used as a stress paradigm. Faecal indicator bacteria (aerobic and anaerobic) were used to assess the microbiological profile of the intestinal flora.��Numbers of C. perfringens were estimated and compared to those of E. coli. Higher numbers of vegetative forms of the anaerobic bacterial indicator C. perfringens were found in stress-exposed animals as compared with controls and with pre-stress conditions.� http://taylorandfrancis.metapress.com/app/...ults,1:102100,1 �Stress also results in increased bacterial adherence and decreased luminal lactobacilli. As a result of all these changes luminal antigens may gain access to the epithelium, causing inflammation.� http://www.blackwell-synergy.com/links/doi...36.2002.01359.x �The balance between host defenses and normal flora (organisms present to some degree in healthy individuals) may be upset by stress and lead to pathological conditions.� http://www.indstate.edu/nurs/mary/pnipost.htm �Natural killer cell activity plays a vital role of the immune system to fight against viral and cancer cells in the body. Secretory IgA is the first line of defense of the immune system lining the gastrointestinal tract, mouth, lungs, urinary tract and other body cavities. Any decline in these levels decreases one�s resistance to bacteria, viruses and parasites. A single five minute experience of anger can produce a significant decrease in secretory IgA up to five hours afterwards.�"

Also another way would be by more than usual diffusion of gas from the blood into the luumen during stress. " diffusion of gas from blood to lumen is determined by visceral tone which in turn is regulated by autonomic nervous system."

Relaxation of the visceral tone causes expansion of gases with resultant decrease in partial pressure of these gases leading to a consequent gradient between the gases in the circulating blood versus those in the lumen

The stress that i suspect,is the one who alter the intestinal mucosa at a cellular level.Stress definition(Webster):-A force exerted to compress or twist another body or parts;-A physical,chemical,or emotional factor that cause bodily or mental tension in disease causation;-...
I think that is more physical than mental.I have a research block in Adobe Acrobe who prove that inflamation is there(IBS).
