Hernia Hernia Risk Factors and Prevention 2

Question 1

Heavy lifting increases hernia risk by what mechanism?

Accepted Answer

Sharply elevating intra-abdominal pressure, forcing abdominal contents through weak areas

Answer

Lifting dramatically spikes intra-abdominal pressure, which can force abdominal contents through pre-existing or newly created fascial defects.

Question 2

Which dietary change helps reduce hernia risk by preventing constipation and straining?

Accepted Answer

High-fiber diet with adequate hydration

Answer

A high-fiber diet promotes regular bowel movements, reducing the need to strain at stool and thereby lowering intra-abdominal pressure spikes.

Question 3

Why does ascites (fluid in the peritoneal cavity) increase hernia risk?

Accepted Answer

It chronically elevates intra-abdominal pressure, expanding pre-existing defects

Answer

Large-volume ascites continuously increases intra-abdominal pressure, causing umbilical and other hernias to enlarge or develop in susceptible individuals.

Question 4

How does prior abdominal surgery increase risk for incisional hernia?

Accepted Answer

Incisions create fascial defects that may not heal fully, becoming weak points

Answer

Surgical incisions disrupt fascial integrity, and impaired healing—due to infection, obesity, or poor nutrition—leaves a weak scar vulnerable to hernia formation.

Question 5

Which comorbidity most significantly impairs wound healing after hernia repair, increasing recurrence risk?

Accepted Answer

Diabetes mellitus

Answer

Diabetes impairs collagen synthesis, reduces immune response, and compromises microvascular perfusion, all of which hinder wound healing and increase recurrence.
