- Mere moments after expiring, body decomposition kicks in as bacterial enzymes start to break down the body's soft tissues and spread throughout the blood vessels. From there, it's a pretty predictable process of putrefaction, then bloat, purge, advanced decay, and finally, dry remains.

What happens to a dead body after 3 weeks in water? After about three weeks in water, a dead body undergoes putrefaction where tissues break down and form the soapy fatty acid known as “grave wax” which halts bacterial growth.
- Stage 1 Fresh (1-2 days) This stage begins almost instantly from the moment of death. As the heart stops beating, the body’s cells gets deprived of oxygen and pH changes occurs.
- Stage 2 Bloated (2-6 days) This stage of decomposition includes the first visible signs of decay, namely the inflation of the abdomen due to a build-up of various gases produced by bacteria inside the body.
- Stage 3 Decay (5-11 days) The previously inflated carcass now deflates and internal gases are released. As the tissues break down the corpse will appear wet and strong odours are very noticeable.
- Stage 4 Post-Decay (10-24 days) By the time this stage is reached, decomposition slows, as most of the flesh has been stripped from the skeleton, though some may remain in denser areas such as the abdomen.
Aug 16, 2021 · Bloating begins a few days after death as gases collect, decomposition around a week or two afterward, and the dry stage (in which the remains largely consist of just bone and other tough materials such as cartilage) is reached a few weeks to a month after the person's demise.
Rigor mortis and livor mortis are typically present in bodies recovered from the water though the onset and waning of these classic postmortem changes may be altered by water temperature, current, changing of body position due to movement, and level of activity prior to death.
3-5 days after death — the body starts to bloat and blood-containing foam leaks from the mouth and nose. 8-10 days after death — the body turns from green to red as the blood decomposes and the organs in the abdomen accumulate gas.
There are many factors that should be considered when understanding how the steps of decomposition, at what rate, and how the body reacts throughout the decomposition process. Here we’ll go over what decomposition in water is and how it can differ from natural body decomposition.

Apr 7, 2024 · Advanced decay - 2-3 weeks after death. Skeletonization - one month to a year after death. Given that there are many variables to consider regarding a body decomposing in water, it is often difficult to determine an exact timeline for the rate of decomposition.
