As part of its constant work to stay healthy, the body continually removes potentially harmful substances through detoxification.
The body’s detoxification system is complex and involves multiple organs, including the liver, kidneys, and skin.
Normal metabolic processes produce toxins endogenously, but the body also acquires them exogenously through exposure to medications and chemicals in food and the environment.
Detoxification involves metabolic processes called biotransformationTrusted Source, during which the alteration of the chemical structure of toxic substances renders them inactive.The body then excretes these substances.
The body’s ability to detoxify depends on various factors, including age, sex, health conditions, genetics, medications, and diet.
For example, because most of the body’s detoxification processes take place in the cells of the liver, liver disease can impair detoxification, which can lead to the buildup of harmful substances such as ammonia.
