Gastric Emptying Transit Time Measured Via SmartPill Study |
The primary outcome of dysmotility will be the measurement of gastric emptying transit time via a SmartPill study. Delayed GET are defined as longer than 5 hours. |
Up to 5 hours |

Small Bowel Transit Time Measured Via SmartPill Study |
The primary outcome of dysmotility will be the measurement of small bowel transit time via a SmartPill study. Delayed SBTT are defined as longer than 6 hours. |
Up to 6 hours |

Colonic Transit Time Measured Via SmartPill Study |
The primary outcome of dysmotility will be the measurement of colonic transit time via a SmartPill study. Delayed CTT is defined as longer than 59 hours. |
Up to 67 hours |

Gastrointestinal Symptom Assessment and Quality of Life, Work, and Productivity Via Questionnaires |
Participants will complete several questionnaires during study participation regarding gastrointestinal symptoms (lower and upper GI). These results will be used to determine overall gastrointestinal involvement and will be correlated with transit time and histologic findings |

Secondary |
Symptom Severity Index |
Patient reported severity of certain symptoms over the last 4 weeks on a scale of 0 to 10 (bloating, abdominal discomfort, incomplete evacuation, straining and urgency). Higher score would mean worse (more symptoms) outcome. |
At 67 hours, data reported over the last 4 weeks |
|
Secondary |
Symptom Frequency Assessment (SFA) |
Patients reported the number of complete BMs they had during the last week (minimum could be 0 and the maximum could be any number greater than 0). Higher/lower scores could be the better or worse outcome (e.g., 0 bowel movements all week would be a worse outcome but over 10 bowel movements would be worse as well), it just depends on the extent. |
At 67 hours, data reported over the last 7 days |

Hamilton Anxiety Rating Scale (HAM-A) |
The scale consists of 14 items, each defined by a series of symptoms, and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where <7 indicates no or minimal severity, 8-14 is mild anxiety, 15-23 is moderate anxiety and 24 and worse is severe anxiety 5. Moderate-severe anxiety was defined as a score of 15 and above. |

Beck's Depression Inventory (BDI) |
Beck's Depression Inventory (BDI): is a 21-item tool assessing the existence and severity of symptoms of depression, as defined by the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV; 1994). The items correspond to symptoms of depression and are a four-point scale for each item ranging from 0 to 3. They are summed to give a single BDI score between 0-63 (where higher results reflect more severe depression). Grades are 1-10: normal, 11-16: mild mood disturbance, 17-20: borderline clinical depression, 21-30: moderate depression, 31-40: severe depression, and >40 extreme depression 6. Moderate-severe depression was defined as a score of 21 and above. |

Work Productivity and Activity Impairment (WPAI) |
Work Productivity and Activity Impairment (WPAI): examines the effect of GI symptoms on loss of work time and loss of productivity. Patients indicated if they are unemployed. For employed patients, scores are presented as percentage of time lost during the last week (hours lost due to GI symptoms out of the hours that patient should have worked, excluding the time lost on participating in the study). Higher percentages indicate greater impairment. Work missed percentage, reduced productivity percentage, and work-productivity impairment percentage (combining the 2 scores) are calculated 7. We defined work/productivity impairment as either being unemployed or having lost 40% or more of work time or productivity. For employed patients, scores are presented as percentage of time lost during the last week (hours lost due to GI symptoms out of the hours that patient should have worked, excluding the time lost on participating in the study). |

IBS Quality of Life (IBS QoL) and Sub-scores |
Irritable bowel syndrome quality of life (IBS-QOL): Assesses bowel specific QOL. It consists of 34 items of a 5-point Likert scale. The total score is summed and then transformed to a 0-100 scale, where 0 is low QoL, and 100 is the best QoL. Different IBS-QOL items can also be categorized to eight subscale scores (Dysphoria, Interference with Activity, Body Image, Health Worry, Food Avoidance, Social Reaction, Sexual, Relationships). Note be made, that the IBS-QOL examines the effect of "bowel problems" on different aspect of QOL, and so was used to assess the effect of gut symptoms on the patients' QOL. Higher scores are better outcome. |

Bristol Stool Scale |
Bristol Stool Scale: patients indicate their last 7 days stool consistency on 1-7 visual scale. The Bristol stool scale correlates with colonic transit time. Higher scores do not indicate better or worse outcomes. It is a visual scale. |
