Fatigue
Fatigue is stated as a common symptom by over half of people with IBS. 160 adults diagnosed with IBS identified low stamina in one study that limits physical activity in work, leisure and social interactions. The analysis of 85 adults found the severity of fatigue predicted by the duration of their symptoms.
IBS is also associated with insomnia, which involves difficulty falling asleep, waking regularly, and feeling uncomfortable in the morning. Thirteen percent reported poor sleep in a survey of 112 adults with IBS. Ironically, the next day, poor sleep indicates more serious gastrointestinal symptoms
