'IBS is a combination of irritable bowel and irritable brain.'
Gut Brain axis
The gut–brain axis is the biochemical signaling that takes place between the gastrointestinal tract (GI tract) and the central nervous system (CNS).[1] The term "gut–brain axis" is occasionally used to refer to the role of the gut flora in the interplay as well, whereas the term "microbiome–gut–brain axis" explicitly includes the role of gut flora in the biochemical signaling events that take place between the GI tract and CNS.[1][2][3]

Scientists are unsure what causes IBS, but a recent study has found that stress could be an important trigger.
Researchers looked at data collected from 552 men and women with Crohn’s disease or colitis. Each participant completed a survey every three months for one year. The surveys asked about, among other things, symptom flare-ups, stressful events and perceived stress. Perceived stress refers to how well patients felt they could deal with their daily worries and difficulties.
The research team found that 174 patients reported a symptom flare-up during the study period, meaning they had a three-month period of symptoms after having been symptom-free the previous three months. For those that reported high levels of perceived stress, the researchers found that patients’ risk of a symptom flare-up more than doubled when preceded by high levels of stress in the previous three months. Of patients who reported a flare-up, 52% had had high perceived stress levels in the preceding three months, compared with 29% of those who remained symptom-free.
The research team also found that the use of antibiotics or anti- inflammatory painkillers — such as aspirin and ibuprofen — and infections such as colds, pneumonia and urinary tract infections had no significant effect on IBS symptoms.
During times of stress, your nervous system kick starts and acts on the lining of the colon, possibly aggravating existing inflammation. There is also evidence that stress hormones could help harmful bacteria take up residence in the intestines, which might, in turn, affect symptoms.
Chronic stress can induce dysbiosis and enhanced bacterial wall adherence, while the interaction between host and microbiota can modulate the neuro-immune-endocrine systems[16], suggesting that stress-induced microbiota alteration of the gut also plays a critical role in the pathogenesis of IBS. It has been reported that the abnormal GI microbiota interacts with the immune system and nervous system, which may cause the GI tract dysfunction by disturbing the brain-gut axis
A strong correlation can also be observed between the severity of IBS and its co-morbid psychiatric disorders, especially depression and anxiety[12,19]. One review about the psychosocial determinants of IBS published in 2013[21], reports a significant increase in stressor score just before progression from IBS non-patient to IBS patient. And also major life traumas (e.g., disruption of a close relationship, a marital separation, a family member leaving home, or break-up of a serious girl/boyfriend relationship) were frequently reported 38 wk prior to onset of IBS symptoms. In addition, other previous studies have demonstrated that early adverse life events (EALs) are associated with the prevalence of IBS.
Just last year, scientists at the University in Illinois looked at the gut microbiota of lean and obese people when they were exercising regularly and when they were sedentary. During periods of exercise, both the lean and obese groups had an increase in the kind of microbes that produce the short-chain fatty acids our bodies need for a whole host of functions, including digestion.
Meditation - relieves stress by relaxing the body and mind using deep breathing and concentration techniques.
