Irritable Bowel Syndrome Message Boards | Re: Low carb, low fat for IBS

I personally eat diary and it doesn't bother me much. It does have fat in it, so that is an issue, as well as if your lactose intolerent or rarer an allergy to it. Some of this depends on how much you consume and how it effects you personally.

Carbs breakdown to serotonin, hence why they may help some people on a low carb diet.

Sugars can create more gut bacteria and heance more gas, chocolates can also increase the release of serotonin in the gut and can upset both gerd and IBS, although it might make c people go more perhaps, it could also contribute to pain.

FYI

Be Choosy About Carbs

simple carbs like fructose can be probelamtic.

also fyi

Since I have suffered for thirty nine years with IBS I wonder what role foods play in IBS. So I asked Dr Douglas Drossman at the UNC Center for Functional GI and Motility disorders and here was his response. This is not a substitute for seeking medical advise from your doctor on any specific conditions you may have, but for educational purposes only.

Dr. Drossman is a Co-director of the Center and Professor of Medicine and Psychiatry at UNC-CH. He established a program of research in functional gastrointestinal disorders at UNC more than 15 years ago and has published more than 250 books, articles, and abstracts relating to epidemiology, psychosocial and quality of life assessment, design of treatment trials, and outcomes research in gastrointestinal disorders.

Dr Drossman's comments on foods for IBS Health.

Shawn,
To say that people with IBS may get symptoms from food intolerances is an acceptable possibility, since the gut will over react to stressors of all types including food (high fat or large volumes of food in particular). Furthermore, there can be specific intolerances. So if you have a lactose intolerance for example, it can exacerbate, or even mimic IBS. Other examples of food substances causing diarrhea would be high consumers of caffeine or alcohol which can stimulate intestinal secretion or with the latter, pull water into the bowel (osmotic diarrhea). The same would be true for overdoing certain poorly absorbed sugars that can cause an osmotic type of diarrhea Sorbitol, found in sugarless gum and sugar substituted foods can also produce such an osmotic diarrhea. Even more naturally, people who consume a large amount of fruits, juices or other processed foods enriched with fructose, can get diarrhea because it is not as easily absorbed by the bowel and goes to the colon where it pulls in water. So if you have IBS, all of these food items would make it worse.

However, it is important to separate factors that worsen IBS (e.g., foods as above, stress, hormonal changes, etc.) from the cause or pathophysiology of IBS. Just like stress doesn't cause IBS, (though it can make it worse), foods must be understood as aggravating rather than etiological in nature.

The cause of IBS is yet to be determined. However, modern research understands IBS as a disorder of increased reactivity of the bowel, visceral hypersensitivity and dysfunction of the brain-gut axis. There are subgroups being defined as well, including post-infectious IBS which can lead to IBS symptoms. Other work using brain imaging shows that the pain regulation center of the brain (cingulate cortex) can be impaired, as well as good evidence for there being abnormalities in motility which can at least in part explain the diarrhea and constipation. So finding a specific "cause" of IBS has grown out of general interest in place of understanding physiological subgroups that may become amenable to more specific treatments. Hope that helps.
