Study Overview
Brief Summary
The purpose of the study is to find out the response of Irritable Bowel Syndrome (IBS) to abdominal fat reduction in central obese patients using: application of High Intensity Focused Ultrasound (cavitation) on the abdominal region, aerobic exercise and a dietary regimen that will be low in calories (Low Caloric Diet) and low in fermentable oligo-, di-, mono- saccharides and polyols (low-FODMAPs).
Detailed Description
Irritable bowel syndrome is a common functional gastrointestinal (GI) disorder, with a high global prevalence and a strong impact on the quality of life. There is a positive association between irritable bowel syndrome (IBS) and increased BMI and volume of android fat, according to waist circumference.
Central obesity and Irritable Bowel Syndrome (IBS) are common medical conditions with similar etiologic mechanisms. There are several studies considering obesity as the risk factor for (IBS), but limited studies that to evaluate the association between abdominal obesity and the incidence of irritable bowel syndrome (IBS). Establishing such association is important in the management of IBS.
Focused ultra sound cavitation is a noninvasive safe technique for reducing localized subcutaneous adipose tissue by generating molecular vibrations that elevate the local tissue temperature and produce rapid cell necrosis in targeted tissues.
the investigators believe that focused ultrasound cavitation could improve the overall of Irritable Bowel Syndrome severity as a consequence of abdominal fat reduction.
To the best of the investigators' knowledge, there are limited studies to confirm the improvement of irritable bowel syndrome (IBS) as a result of abdominal fat reduction by focused ultrasound cavitation.

Arms & Interventions
study group (Group A)
Will consist of 30 cases suffering from mild to moderate Irritable Bowel Syndrome (IBS) with mild to moderate obesity will receive High Intensity Focused Ultrasound (Cavitation), a dietary regimen that combines Low Caloric Diet (LCD) and low (FODMAPs) diet and aerobic exercises with moderate intensity.
Intervention: focused ultrasound (Procedure)

Will consist of 30 cases suffering from mild to moderate Irritable Bowel Syndrome (IBS) with mild to moderate obesity will receive High Intensity Focused Ultrasound (Cavitation), a dietary regimen that combines Low Caloric Diet (LCD) and low (FODMAPs) diet and aerobic exercises with moderate intensity.
Intervention: Low Caloric Diet (LCD) and a low (FODMAPs) diet (Behavioral)

Will consist of 30 cases suffering from mild to moderate Irritable Bowel Syndrome (IBS) with mild to moderate obesity will receive High Intensity Focused Ultrasound (Cavitation), a dietary regimen that combines Low Caloric Diet (LCD) and low (FODMAPs) diet and aerobic exercises with moderate intensity.
Intervention: aerobic exercise (Other)

Outcomes
Primary Outcomes
change in abdominal subcutaneous fat percentage
Time Frame: change from baseline abdominal subcutaneous fat percentage at 12 weeks
abdominal subcutaneous fat percentage will be measured by Dual-energy X-ray Absorptiometry (DXA)
change in total body fat percentage
Time Frame: change from baseline total body fat percentage at 12 weeks
total body fat percentage will be measured by Dual-energy X-ray Absorptiometry (DXA)
change in abdominal visceral fat percentage
Time Frame: change from baseline abdominal visceral fat percentage at 12 weeks
abdominal visceral fat percentage will be measured by Dual-energy X-ray Absorptiometry (DXA)
change in Irritable bowel syndrome Severity Scoring system (IBS-SSS)
Time Frame: change from baseline Irritable bowel syndrome Severity Scoring system at 12 weeks
The Irritable bowel syndrome Severity Scoring System (IBS-SSS) questionnaire was validated by Francis et al. in 1997and consists of five questions that measure: (1) abdominal pain severity; (2) frequency (number of days in every 10 days) with abdominal pain; (3) abdominal bloating/distension; (4) satisfaction with bowel habits; (5) IBS-related quality of life (QoL). Each measure is rated from 0 to 100, with total scores ranging from 0 to 500
change in Irritable bowel syndrome-quality of life (IBS-QOL)
Time Frame: change from baseline Irritable bowel syndrome-quality of life at 12 weeks
The Irritable bowel syndrome-quality of life questionnaire (IBS-QOL) consists of 34 items assessing patients' well-being across eight subscales: dysphoria (eight items); interference with activity (seven items); body image (four items); social reaction (four items); health worry (three items); food avoidance (three items); relationships (three items); and sexual (two items)
Secondary Outcomes
- change in body weight(change from baseline body weight at 12 weeks)
- change in waist circumference measurement(change from baseline Waist circumference at 12 weeks)
- change in body mass index(change from baseline body mass index at 12 weeks)
