Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine and causes symptoms such as abdominal pain, bloating, cramping, gas, diarrhea, and constipation, which are usually chronic.

Understanding when to expect an episode may assist you in coping with the symptoms better and minimize their interference with your life.
What Is an IBS Flare-Up?

An IBS flare-up suggests an interval when indications all a sudden worsen or grow to be extra intense than common. People may then experience sharp stomach cramps, increased need to go to the bathroom, lots of diarrhea or constipation and visible bloating during these episodes.

A handful of flare-ups last for only hours or a couple of days. Typically associated with transient stimuli including spicy or fatty foods, caffeine, and mild stress.
Moderate Flare-Ups
Flare-ups last from three to seven days for most. This tends to happen in the context of overlapping triggers, such as bad sleep, dietary irritants, and emotional stress.
Long-Lasting Episodes
Flare-ups may linger, however, for days, weeks or even months. This often occurs when IBS is undertreated, when trigger exposure is persistent, or when people have higher accompanying levels of chronic stress, or anxiety.
In summary, IBS flare-ups usually last from two to five days in total, but there is no set time frame, as IBS is a chronic condition that comes and goes at random.

For some females, hormone changes —especially around the time of their periods— affect the length and duration of movements in the intestines and prolong their IBS symptoms.
