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. Therefore, this study is a trial to investigate the effect of focused ultrasound cavitation augmented with aerobic exercise and dietary regimen on improvement of Irritable bowel syndrome (IBS) in patients with central obesity. Sixty volunteer central obese patients (males and females) with Irritable Bowel Syndrome (IBS) which will be diagnosed according to Rome IV criteria will be participated in this study and will be referred from the Gastroenterology outpatient clinic of El-Sahel Teaching Hospital, Cairo. The study will be conducted at El-Sahel Teaching Hospital.
Interventions
PROCEDUREfocused ultrasound
focused ultra sound cavitation using a device of Mabel6 DUO Ultra Cavitation Technology system produced by DAEYANG MEDICAL COMPANY, KOREA will be applied on the abdominal region which extending bilaterally from the line extending from mid axilla to iliac crest, and above from center of diaphragm to the line extending between two iliac crest below. the session of Focused Ultra Sound will take 25- 30 minutes, twice/week and with about three day intervals for 12 weeks.
BEHAVIORALLow Caloric Diet (LCD) and a low (FODMAPs) diet
The Low caloric diet (LCD) diet will be an equilibrated diet that had a caloric value 10% below the total metabolic expenditure (total energy expenditure) of each individual. The low FODMAPs diet (LFD) is a diet low in fermentable oligo-, di-, mono- saccharides and polyols (FODMAPs).
OTHERaerobic exercise
aerobic exercise program under direct supervision at a frequency of 3 times/week for 12 weeks, in the form of walking on a treadmill for 30 minutes with moderate intensity (12-14) according to The Borg Rating of Perceived Exertion (RPE) scale.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| change in total body fat percentage | 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 subcutaneous fat percentage | 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 abdominal visceral fat percentage | 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) | 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) | 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
| Measure | Time frame | Description |
|---|---|---|
| change in body weight | change from baseline body weight at 12 weeks | Weight scale will be used to measure the weight (in kilograms) of all patients in both groups (A & B) |
| change in body mass index | change from baseline body mass index at 12 weeks | Body Mass Index (BMI) is calculated as body weight (in kilograms) divided by the square of body height (in meters) (BMI= Kg/m²) |
| change in waist circumference measurement | change from baseline Waist circumference at 12 weeks | Waist circumference (WC) will be measured (in centimeters) by the tape measurement at the midway between the lowest rib and the iliac crest, while the patient in the standing position with light clothes and at the end of expiration |
