Encouraging healthy dietary habits and positive lifestyle factors are undeniably the most substantial non-pharmacologic factor for the deterrence and management of causative aspects of irritable bowel syndrome. The ingestion of probiotics in right ratio and curtailing certain foods has posed encouraging favorable impacts on the gut health and worthy living. Accordingly, this article reviews the importance of probiotics and low FODMAP diet that nurtures the prime concerns to be reflected by the experts in the exploration of dietary trials as alternatives for patients affected with irritable bowel syndrome.
The gastrointestinal tract is the longest and the largest area, approximately 7m in length, encompassing 300m2 surface area in adults, interlocking various organs that are involved in bio-conversion, absorption and utilization of nutrients from the food, thus providing nourishment to the entire body. More than 1000 species of microbial flora are present in the human large intestine, the most common strains being lactobacilli, bifido bacterium, streptococci and saccharomyces. The dawn of the role of food and microbes in the gut though dates back to million years ago, feasting on more of unhealthy, refined, calorie dense, junk foods without roughage in recent times have drawn all over again the insights into the micro biota of the human G.I system. The list of Gastro intestinal diseases being Gastroesophageal Reflux Disease (GERD), Irritable Bowel Syndrome (IBS), Gall stones, Celiac disease, Crohn’s Disease, Haemorrhoids, and Diverticulitis, Irritable bowel syndrome is a common gastrointestinal disorder affecting approximately 10-15 % of the world population, mostly women and children for which the treatment is utterly diet- centric. According to The Rome III diagnostic criteria IBS is defined as the condition with recurrent abdominal discomfort or pain for at least 3 days / month, for a period of 3 months, with symptom onset at least 6 months prior to diagnosis, associated with two or more of the following:
a) Improvement with defecation
b) Onset associated with the change in frequency of stool
c) Onset associated with change in form / appearance of stool.
The symptoms involve an anomalous infirmity of gut motility with amplified gut feelings accompanied by abdominal pain, loss of appetite, abdominal discomfort, flatulence, bloating, stools with mucous, and irregular bowel habits with constipation (IBS-C) or watery stools (IBS-D) or alternating episodes of diarrhea and constipation (IBS-A).
IBS management involves a multiple interlinked factors like diet, lifestyle intervention, counseling and medications.
The change in food consumption styles, due to transformation of life style of women has led to a striking home and work imbalance. This has made them to concentrate less on food preparations and the tendency to purchase readily available, ready to eat, ready to serve, processed and packed food products is steadily increasing. As a result of which, the intake of freshly prepared fermented food products consumption has declined. This has headed to origin of many G.I diseases. A well balanced diet with nutrients from all the food groups and non- nutritional factor like fibre in right proportions will aid in maintaining a normal G.I. system. In addition, the presence of favorable microbial mass helps to enhance the functions of gut. Avoidance of foods that trigger the symptoms of IBS is also a must and formulation of personalized diet is mandatory.
a) Probiotics The diet rich in probiotics, a group of beneficial microbes found in many of the traditional diets have proved successful in alleviating IBS. The following table presents the list of various genus of microbes and their species proved to be probiotics, their food sources and function in managing IBS.
b) Low FODMAP Diet
FODMAP, the acronym for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols is a pool of particles in food, which are poorly absorbed by people with poor gastrointestinal functioning. The Oligosaccharides namely fructans and galactooligosaccharides (GOS), Disaccharides viz. lactose in milk, Monosaccharides like fructose and the Polyols like sorbitol and mannitol are not readily absorbed by Small Intestine leading to the symptoms of IBS. Hence a diet low in FODMAPs developed in Australia is promising in treating and managing IBS. The three stages of a Low FODMAP diet include:
A calm, stress free life with periodic aerobic exercises like walking, jogging, cycling help relieve stress. The awareness on Yoga and laughter therapy are also on steady raise and are providing a helping hand to overcome stress.
The patients often hesitate to share the signs and symptoms of any gastrointestinal diseases as well IBS in particular. The treatment can prove efficacious only if the co-operation is extended to the doctors. The studies have proven that low FODMAP diet is successful if the patient is determined and has the perseverance to follow till the symptoms disappear. Hence, the Patient – Doctor – Dietician team approach is the only prolific way to manage IBS.
