Bloating, skin slippage, and discoloration on decomposing remains

Associated with putrefaction is the production of gases. These gases, primarily located in the abdomen, cause the body to become distended or bloat. This bloating can cause the affected areas of the body to expand dramatically. Over time the affected areas may rupture or the gas may subside naturally. Skin slippage, or the shedding of the epidermis from the body caused by the deterioration of the junction between the dermis and epidermis, is also associated with early decomposition processes. Many local environmental factors affect the decomposition process, including temperature, moisture, and soil chemistry, but the processes of autolysis and putrefaction are responsible for the chemical breakdown of tissues.
