Which embalming-related issue is most likely observed with advanced decomposition?

• A. Gas buildup and leakage
• B. Increased bone density
• C. Complete dehydration
• D. Immediate rigor

Answer: (A)

Gas buildup and leakage is seen in advanced decomposition because bacteria driving putrefaction produce gases such as methane, hydrogen, and hydrogen sulfide as tissues break down. Those gases accumulate in body cavities and under the skin, causing distension and often leading to purge leaking from the mouth, nose, or incisions. This gas production and resulting leakage are hallmarks of late-stage decay and present significant challenges for embalming and preservation. Increased bone density doesn’t occur with decomposition, dehydration isn’t the defining feature of advanced decay, and rigor mortis is an early change that typically resolves before decomposition progresses to this stage.
