Concept
Detoxification
Summary
Detoxification or detoxication (detox for short) is the physiological or medicinal removal of toxic substances from a living organism, including the human body, which is mainly carried out by the liver. Additionally, it can refer to the period of drug withdrawal during which an organism returns to homeostasis after long-term use of an addictive substance. In medicine, detoxification can be achieved by decontamination of poison ingestion and the use of antidotes as well as techniques such as dialysis and (in a limited number of cases) chelation therapy.
Many alternative medicine practitioners promote various types of detoxification such as detoxification diets. Scientists have described these as a "waste of time and money". Sense about Science, a UK-based charitable trust, determined that most such dietary "detox" claims lack any supporting evidence.
The liver and kidney are naturally capable of detox, as are intracellular (specifically, inner membrane of mitochondria or in the endoplasmic reticulum of cells) proteins such as CYP enzymes. In cases of kidney failure, the action of the kidneys is mimicked by dialysis; kidney and liver transplants are also used for kidney and liver failure, respectively.
Alcohol detoxification
Alcohol detoxification is a process by which a heavy drinker's system is brought back to normal after being habituated to having alcohol in the body continuously for an extended period of substance abuse. Serious alcohol addiction results in a downregulation of GABA neurotransmitter receptors. Precipitous withdrawal from long-term alcohol addiction without medical management can cause severe health problems and can be fatal. Alcohol detox is not a treatment for alcoholism. After detoxification, other treatments must be undergone to deal with the underlying addiction that caused alcohol use.
Drug detoxification
Clinicians use drug detoxification to reduce or relieve withdrawal symptoms while helping an addicted person adjust to living without drug use; drug detoxification does not aim to treat addiction but rather represents an early step within long-term treatment.
