- 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.
Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. [1]
Human decomposition is a natural process involving the breakdown of tissues after death. While the rate of human decomposition varies due to several factors, including weather, temperature, moisture, pH and oxygen levels, cause of death, and body position, all human bodies follow the same four stages of human decomposition.

- 4 Postmortem Stages of Death. After death, the body undergoes a series of changes that occur in a timely and orderly manner. These stages are also affected by the extrinsic and intrinsic factors of the corpse.
- Pallor Mortis. The first change that occurs in a corpse is the increased paleness in the face and other parts. This is due to the cessation of blood circulation.
- Algor Mortis. Humans are warm-blooded organisms, which means that we maintain a constant internal temperature, regardless of the outside environment. The brain is our thermostat, and the circulatory system is the main heat dissipator.
- Rigor Mortis. Immediately after death, a corpse will go flaccid. All the muscles will become relaxed and limp, but the whole body will stiffen after a few hours.

Jul 24, 2023 · The human body undergoes sequential changes after death due to a combination of internal and external factors. These changes primarily serve in estimating the post mortem interval. Besides, these provide other useful information relating to the cause and manner of death too.
