The age of patients ranged from 15 to 55 years, more than one-third of them located in the age range between 15 and 25. The statistical analysis reported a significant correlations between having IBS for three successive days for 3 months regarding age and duration of IBS (P value <0.001), having depression or anxiety before, and if the depression affects IBS symptoms or not (P value = 0.013 and <0.001, respectively). Having dietary regimen, advising to increase fibers, thinking about changing diet improves IBS symptoms (P value = 0.001, 0.005, and < 0.001, respectively) and having treatment (P value = 0.006).
