When a person passes away or sustains a traumatic injury, the body immediately begins to change. If you’re dealing with the aftermath of a violent trauma or unattended death, read this post to learn how blood and body fluids change as they decay. We’ll also explain why professional cleanup is necessary.

The First Few Hours

In the initial hours after death, the body starts decomposing almost immediately. In a process known as livor mortis, blood settles due to gravity and begins to pool in the lower areas of the body. The blood still looks relatively fresh at this stage, but it will soon start to lose oxygen. This transformation will gradually change its color from bright red to a deep maroon or even black.

Other fluids—including lymph, cerebrospinal, and interstitial fluids—also begin to shift. As the body’s cells break down, they release enzymes that contribute to the decay process. These enzymes affect internal tissues and interact with bodily fluids, changing their chemical composition and accelerating decomposition.

Day One to Day Three

Over the next few days, bacteria within the body multiply rapidly. These microbes are especially active in the digestive tract but exist throughout the body. They produce gases and acids that break down tissue and cause bloating.

As this internal activity continues, blood and body fluids become more unstable and hazardous. Hemoglobin in the blood starts to degrade, turning the liquid darker and more viscous. Other bodily fluids may leak from orifices as well. This stage is when visual and olfactory signs of decomposition become unmistakable.

The Health Hazards of Fluid Decay

Decomposing fluids pose several hazards. For instance, the byproducts of decaying blood and fluids can contain pathogens such as hepatitis, HIV, and various bacteria. These fluids can soak into carpets, wood, and subflooring, creating long-term contamination risks and potentially causing structural damage.

Environmental Factors That Affect Decay

Environmental conditions play a critical role in how quickly fluids decay. Warmer environments can speed up the breakdown process, while colder conditions slow it down. Humidity matters, too. Moist areas promote bacterial growth, accelerating decay, and dry conditions preserve fluids for longer.

Effective Cleanup Requires Professional Expertise

Attempting to clean decayed bodily fluids yourself can amplify the risks. Standard household cleaning solutions are insufficient to remove pathogens and prevent long-term contamination. That’s why you should call Affinity Bio Solutions instead.
