Background And Purpose:
Functional abdominal bloating (FAB) is defined as a subjective sensation of increased abdominal pressure and is more common in females. Due to the proximity to the abdominal wall spinal related factors of curvature, abdominal muscle function may be related to FAB. This study aimed to compare spinal-related musculoskeletal factors between females with and without FAB.
Methods:
This was a case-control study of 90 females aged 18-60 years categorized as FAB (n = 45, mean age 39.24 ± 7.40 years) and control (n = 45, mean age 38.56 ± 7.45 years) groups. Thoracic and lumbar curvatures, abdominal muscle force and endurance were measured and compared between the groups. Independent t-test was used to compare the musculoskeletal variables between groups. A logistic regression model was used to determine which variables associated with FAB.
Results:
Spinal curvatures did not differ between groups (p > 0.05), but abdominal muscle force and endurance were lower in the FAB group than the control group (p < 0.05). Abdominal muscle force was associated with FAB (p = 0.03).
Discussion:
This case-control study reported decreased abdominal muscle force and endurance in females with FAB and identified abdominal muscle force as a potential significant contributor to FAB. Further investigation of abdominal muscle strength as a possible target for managing FAB is warranted.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Irritable Bowel Syndrome II: Clinical Features and Diagnostic Evaluation
Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:
Irritable Bowel Syndrome I: Introduction
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Appendicitis-I: Introduction
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
