Intermittent fasting (IF) has become popular in recent years for its potential to help with weight management, metabolic health, and digestive wellness . Although many people experience great benefits from following an intermittent fasting schedule, it is crucial to remember that fasting can present differently for individuals with Irritable Bowel Syndrome (IBS). IBS is a functional gastrointestinal disorder with presenting symptoms of abdominal pain, bloating, a change in bowel habits, and heightened gut sensitivity.
There are various forms of intermittent fasting,


• The 5-2 plan, where people eat substantially lower calories on two non-consecutive days and have normal food on the remaining five days

• The 24-hour fasting method, in which nothing is eaten for a full day

• The trendy 16 - 8 diet, where eating is limited to an 8-hour period and fasting for the other 16 hours of the day
Though each has its own rhythm and structure, not all are ideal for those living with IBS symptoms .
In certain individuals, the Intermittent fasting may also be helpful. Dietary habits could be beneficial in that it introduces diversity in gut microbiome as well as increasing the population of beneficial gut microorganisms. Intensified gut flora may boost digestion and decrease inflammation, that could relax IBS symptoms. Fasting can also reduce the processes of the normal digestive tract, like gut motility. When people skip breakfast, when regular bowel motions are typically operating at their best, this decrease in the process cause interfere with colonic reflexes. This interference may result in bloating, constipation, incomplete feces, and an overall feeling of gastrointestinal discomfort. When trying long-term fasting diets, many IBS sufferers complain of further indigestion, constipation, and even nausea. Since irritation upon fasting is prevalent, these side effects not only worsen the physical distress but also affect mood and mental acuity. Intermittent fasting is not a blanket solution for individuals with IBS, although it may be effective for some. To find out what will work best for everyone without negatively affecting gut health or overall health, individualized diet plans and professional consultation are the key.
