IBS/Celiac/Non-Gluten Sensitivity

IBS/Celiac/Non-Gluten Sensitivity

Do you suffer from any of these uncomfortable conditions?

IBD

  • Recurrent abdominal pain or discomfort
  • Abnormal stool frequency (greater than 3 bowel movements/day or less than 3 bowel movements/week
  • Abnormal stool form (lumpy/hard or loose/watery stool)
  • Abnormal stool passage (straining, urgency, or feeling of incomplete bowel movement)
  • Bloating or feeling of abdominal distension
  • Frequent gas
  • Feelings of urgency (the need to find a restroom fast)

Irritable bowel syndrome (IBS or spastic colon) is a diagnosis of exclusion. It is a functional bowel disorder characterized by chronic abdominal pain, discomfort, bloating, and alteration of bowel habits in the absence of any detectable organic cause. In some cases, the symptoms are relieved by bowel movements. Diarrhea or constipation may predominate, or they may alternate IBS may begin after an infection, a stressful life event, or onset of maturity without any other medical indicators.

Although medical experts say there is no cure for IBS, I totally disagree-and so do my patients.

There are treatments that attempt to relieve symptoms, including dietary adjustments, supplementation and medication. If you want to get rid of it you need to find out why you have it in the first place. The answer will surprise some and most already know but refuse to believe it. We find it and tell you. Most patients can start feeling relief in 2-6 weeks and following advice within 3-6 months can be clear of symptoms. There are a few “deal breakers” that may need to be addressed first that prevent you from getting better. I look for those first to make an accurate diagnosis.

Celiac Disease

Several conditions may present as IBS including celiac disease (gluten intolerance), Fructose mal-absorption, mild infections, parasitic infections like giardiasis, several inflammatory bowel diseases, functional chronic constipation, and chronic functional abdominal pain. In IBS, routine clinical tests yield no abnormalities, though the bowels may be more sensitive to certain stimuli. The most common theory is that IBS is a disorder of the interaction between the brain and the gastrointestinal tract, and also be abnormalities in the gut flora or the immune system. This is why we perform a very though neurologic evaluation.

These so-called experts say that IBS does not lead to more serious conditions in most patients. But it is a source of chronic pain, fatigue, and other symptoms, and it increases a patient’s medical costs, and contributes to work absenteeism. Again as I disagree, digestive issues are the cause of most chronic disease out there like auto immune conditions, thyroid diseases, arthritis, anemia, gastro-esophageal reflux (GERD), symptoms relating to the genitourinary system, psychiatric symptoms such as depression and anxiety, fibromyalgia, chronic fatigue syndrome, headache and backache and many more including something you may have not of heard of COLON CANCER!!!

Did you know your gut is also called the 2nd brain? Believe it or not many patients with digestive problems do not even know they have a problem with their digestion because they have no bowel issues. Many times gut issues show up as multiple sclerosis, anxiety problems, inflammatory arthritis, depression, chronic neck or back pain, hormone problems and many others. In kids it can manifest as ADD/ADHD, asthma, allergies (adults too) and autistic disorders.

History

One of the first references to the concept of an “irritable bowel” appeared in the Rocky Mountain Medical Journal in 1950.

The term was used to categorize patients who developed symptoms of diarrhea, abdominal pain, constipation, but where no well-recognized infective cause could be found. Early theories suggested that the irritable bowel was caused by a psychosomatic or mental disorder since no physical manifestation was found.

Classification

IBS can be classified as either diarrhea-predominant (IBS-D), constipation-predominant (IBS-C) or IBS with alternating stool pattern (IBS-A or pain-predominant). In some individuals, IBS may have an acute onset and develop after an infectious illness characterized by two or more of the following: fever, vomiting, diarrhea, or positive stool culture. This post-infective syndrome has consequently been termed “post-infectious IBS” (IBS-PI).

Symptoms

The primary symptoms of IBS are abdominal pain or discomfort in association with frequent diarrhea or constipation, a change in bowel habits. There may also be urgency for bowel movements, a feeling of incomplete evacuation (tenesmus), bloating or abdominal distention. People with IBS, more commonly than others, have gastro-esophageal reflux, symptoms relating to the genitourinary system, chronic fatigue syndrome, fibromyalgia, headache, backache and psychiatric symptoms such as depression and anxiety. Some studies indicate that up to 60% of persons with IBS also have a psychological disorder, typically anxiety or depressions.

Causes

The cause of IBS is unknown, but several hypotheses have been proposed. The risk of developing IBS increases six-fold after acute gastrointestinal infection. Post-infection, further risk factors are young age, prolonged fever, anxiety, and depression. Publications suggesting the role of brain-gut “axis” appeared in the 1990s, such as a study entitled Brain-gut response to stress and cholinergic stimulation in IBS published in the Journal of Clinical Gastroenterology in 1993. A 1997 study published in Gut magazine suggested that IBS was associated with a “derailing of the brain-gut axis.” Psychological factors may be important in the etiology of IBS.

Active infections

Prevalence of protozoal infections in industrialized countries (United StatesandCanada) in 21st century:

There is research to support IBS being caused by an as-yet undiscovered active infection. Other researchers have focused on an unrecognized protozoal infection as a cause of IBS as certain protozoal infections occur more frequently in IBS patients. Two of the protozoa investigated have a high prevalence in industrialized countries and infect the bowel, but little is known about them as they are recently emerged pathogens.

Blastocystis is a single-cell organism that has been reported to produce symptoms of abdominal pain, constipation and diarrhea in patients though these reports are contested by some physicians. Studies from research hospitals in various countries have identified high Blastocystis infection rates in IBS patients, with 38% being reported fromLondonSchoolof Hygiene & Tropical Medicine, 47% reported from the Department of Gastroenterology atAga KhanUniversityinPakistanand 18.1% reported from theInstituteofDiseasesand Public Health atUniversityofAnconainItaly. Reports from all three groups indicate a Blastocystis prevalence of approximately 7% in non-IBS patients. Researchers have noted that clinical diagnostics fail to identify infection, and Blastocystis may not respond to treatment with common antiprotozoals.

Dientamoeba fragilis is a single-cell organism that produces abdominal pain and diarrhea. Studies have reported a high incidence of infection in developed countries, and symptoms of patients resolve following antibiotic treatment. One study reported on a large group of patients with IBS-like symptoms who were found to be infected with Dientamoeba fragilis, and experienced resolution of symptoms following treatment. Researchers have noted that methods used clinically may fail to detect some Dientamoeba fragilis infections. It is also found in people without IBS.

Diagnosis

There is no specific laboratory or imaging test that can be performed to diagnose irritable bowel syndrome. Diagnosis of IBS involves excluding conditions that produce IBS-like symptoms, and then following a procedure to categorize the patient’s symptoms. Ruling out parasitic infections, lactose intolerance, small intestinal bacterial overgrowth and celiac disease is recommended for all patients before a diagnosis of irritable bowel syndrome is made. In patients over 50 years old it is recommended that they undergo a screening colonoscopy.

Differential diagnosis

Coloncancer, inflammatory bowel disease, thyroid disorders and giardiasis can all feature abnormal defecation and abdominal pain. Less common causes of this symptom profile are carcinoid syndrome, microscopic colitis, bacterial overgrowth, and eosinophilic gastroenteritis. IBS is, however, such a common presentation and testing for these conditions would yield such low numbers of positive results that it is considered difficult to justify the expense. Because there are many causes of diarrhea that give IBS-like symptoms, the American Gastroenterological Association published a set of guidelines for tests to be performed to rule out other causes for these symptoms. These include gastrointestinal infections, lactose intolerance, and coeliac disease. Research has suggested that these guidelines are not always followed. Physicians may choose to use one of these guidelines, or may simply choose to rely on their own anecdotal experience with past patients. The guidelines may include additional tests to guard against misdiagnosis of other diseases as IBS. Such “red flag” symptoms may include weight loss, gastrointestinal bleeding, anemia, or nocturnal symptoms. However, researchers have noted that red flag conditions may not always contribute to accuracy in diagnosis — for instance, as many as 31% of IBS patients have blood in their stool many possibly from hemorrhoidal bleeding.

The diagnostic algorithm identifies a name that can be applied to the patient’s condition based on the combination of the patient’s symptoms of diarrhea, abdominal pain, and constipation. For example, the statement “50% of returning travelers had developed functional diarrhea while 25% had developed IBS” would mean that half the travelers had diarrhea while a quarter had diarrhea with abdominal pain. While some researchers believe this categorization system will help physicians understand IBS, others have questioned the value of the system and suggested that all IBS patients have the same underlying disease but with different symptoms. On this line is a recent study, which showed that constipation and/or diarrhea seems to be different manifestations of the same underlying condition, that is a build-up of fecal retention reservoirs in the colon. Abdominal X-rays were analyzed for colon transit time and fecal distribution, which correlated significantly with bloating and abdominal pain. Thus a group of patients were identified with an increased fecal loading compared to controls, but having a colon transit time equal or less to the controls. This suggests that defecation patterns do not reflect the amount of feces in the colon and is called hidden constipation. This phenomenon may be linked to bacterial overgrowth.

Misdiagnosis

Published research has demonstrated that some poor patient outcomes are due to treatable causes of diarrhea being misdiagnosed as IBS. Common examples include infectious diseases, coeliac disease, Helicobacter pylori, and parasites.

Celiac disease in particular is often misdiagnosed as IBS. TheAmericanCollegeof Gastroenterology recommends that all patients with symptoms of IBS be tested for celiac disease. Chronic use of certain sedative-hypnotic drugs especially the benzodiazepines may cause irritable bowel like symptoms that can lead to a misdiagnosis of irritable bowel syndrome.

Co-morbidities

Researchers have identified several medical conditions, or comorbidities, which appear with greater frequency in patients diagnosed with IBS.

Headache, Fibromyalgia, Chronic fatigue syndrome and Depression: A study of 97,593 individuals with IBS identified co-morbidities as headache, fibromyalgia, and depression. A systematic review found that IBS occurs in 51% of chronic fatigue syndrome patients and 49% of fibromyalgia patients, and psychiatric disorders were found to occur in 94% of IBS patients.

Inflammatory bowel disease (IBD): Some researchers have suggested that IBS is a type of low-grade inflammatory bowel disease. See here for more details.

Abdominal surgery: A recent (2008) study found that IBS patients are at increased risk of having unnecessary cholecystectomy (gall bladder removal surgery) not due to an increased risk of gallstones, but rather to abdominal pain, awareness of having gallstones, and inappropriate surgical indications. A 2005 study reported that IBS patients are 87% more likely to undergo abdominal and pelvic surgery, and three times more likely to undergo gallbladder surgery. A study published in Gastroenterology came to similar conclusions, and also noted IBS patients were twice as likely to undergo hysterectomy.

Endometriosis: One study reported a statistically significant link between migraine headaches, IBS, and endometriosis.

Other chronic disorders: Interstitial cystitis may be associated with other chronic pain syndromes, such as irritable bowel syndrome and fibromyalgia.

Diet

Some people with IBS are likely to have food intolerances. In 2007 the evidence base was not strong enough to recommend restrictive diets.

Many different dietary modifications have been attempted to improve the symptoms of IBS. Some are effective in certain sub-populations. As lactose intolerance and IBS have such similar symptoms a trial of a lactose free diet is often recommended. A diet restricting fructose and fructan intake has been shown to successfully treat the symptoms in a dose-dependant manner in patients with fructose mal-absorption and IBS.

While many IBS patients believe they have some form of dietary intolerance, tests attempting to predict food sensitivity in IBS have been disappointing. One study reported that an IgG antibody test was effective in determining food sensitivity in IBS patients, with patients on the elimination diet experiencing 10% greater symptom reduction than those on a sham diet.

There is no evidence that digestion of food or absorption of nutrients is problematic for those with IBS at rates different from those without IBS. However, the very act of eating or drinking can provoke an overreaction of the gastrocolic response in some patients with IBS due to their heightened visceral sensitivity, and this may lead to abdominal pain, diarrhea, and/or constipation.

Research

Gibson and Shepherd state a diet restricted in fermentable oligo di and monosaccharides and polyols (FODMAPs) now has an evidence base sufficiently strong to recommend its widespread application in conditions such as IBS and IBD. They also state the restriction of FODMAPs globally, rather than individually, controls the symptoms of functional gut disorders (e.g., IBS), and the majority of IBD patients respond just as well. It is more successful than restricting only fructose and fructans, which are also FODMAPs, as is recommended for those with fructose malabsorption. Longer term compliance with the diet was high.

A randomized controlled trial on IBS patients found relaxing an IgG-mediated food intolerance diet led to a 24% greater deterioration in symptoms compared to those on the elimination diet and concluded food elimination based on IgG antibodies may be effective in reducing IBS symptoms and is worthy of further biomedical research.
