Intraabdominal pressure (IAP) in healthy adults increases with higher body mass index (BMI) but does not differ by sex. Activities like coughing and jumping generate the highest IAP, potentially increasing hernia risk in susceptible individuals.
Area of Science:
- Physiology
- Medical Diagnostics
Background:
- Intraabdominal pressure (IAP) is implicated in abdominal catastrophes and hernia formation.
- Limited data exists on normal IAP ranges in healthy individuals.
Purpose of the Study:
- To measure the normal range of IAP in healthy adults.
- To correlate IAP with sex and body mass index (BMI).
Main Methods:
- 20 healthy adults (<30 years) underwent IAP measurement via transurethral bladder catheter.
- Subjects performed 13 different physical tasks.
- Data analyzed using Student's t-test and Pearson's correlation.
Main Results:
- Mean IAP was 16.7 mm Hg (sitting) and 20 mm Hg (standing).
- Coughing and jumping produced the highest IAP (107.6 and 171 mm Hg).
- Higher BMI correlated with increased IAP in 5 of 13 exercises; no sex differences observed.
Conclusions:
- Normal IAP correlates with BMI but not sex.
- Coughing and jumping generate peak IAP.
- Elevated IAP in high-BMI patients with chronic cough may increase hernia risk.
