Question

During which stage of postmortem decomposition does the body become bloated with gas?

Answer 1

Once the bloold stop circulating through the body, a decomposition process start, five stages take the body from fresh to dry or remains, one the stages is Bloat, and that is a process where the body begins liquefying the tissues and transforming proteins and carbs into gases such as methane, nitrogen, carbon dioxide and hydrogen sulfide, producing at first, distention  of the stomach, spreading through the whole body. The increase of gas pressure combined with the presence of liquids, give the body a bloat look and all that elements are forced to leave the body through natural orifices, or because of the weak conditions of the skin, they may break it to scape the body.
