Detoxification

From Wikipedia, the free encyclopedia
This article is about the removal of toxic substances from a living organism. For other uses, see Detoxification (disambiguation).

Detoxification (detox for short)[1] is the physiological or medicinal removal of toxicsubstances from a living organism, including, but not limited to, the human body, which is mainly carried out by the liver. Additionally, it can refer to the period of withdrawal during which an organism returns to homeostasis after long-term use of an addictive substance.[2][3] 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.[4]

Many alternative medicine practitioners promote various types of detoxification such as detoxification diets. Scientists have described these as a “waste of time and money”.[5][6]Sense About Science, a UK-based charitable trust determined that most such dietary “detox” claims lack any supporting evidence.[7][8]

Types of detoxification

Alcohol detoxification

Alcohol detoxification is a process by which a heavy drinker’s system is brought back to normal after being used to having alcohol in the body continually. Serious alcohol addiction results in a downregulation of GABA neurotransmitter receptors. Precipitous withdrawalfrom 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 the alcohol use.

Drug detoxification

Main article: Drug detoxification

Clinicians use drug detoxification to reduce or relieve withdrawal symptoms while helping an addicted individual adjust to living without drug use; drug detoxification does not aim to treat addiction but rather represents an early step within long-term treatment. Detoxification may be achieved drug-free or may use medications as an aspect of treatment. Often drug detoxification and treatment will occur in a community program that lasts several months and takes place in a residential setting rather than in a medical center.

Drug detoxification varies depending on the location of treatment, but most detox centers provide treatment to avoid the symptoms of physical withdrawal from alcohol and from other drugs. Most also incorporate counseling and therapy during detox to help with the consequences of withdrawal.

Metabolic detoxification

An animal’s metabolism can produce harmful substances which it can then make less toxic through reduction, oxidation (collectively known as redox reactions), conjugation and excretion of molecules from cells or tissues.[9] This is called xenobiotic metabolism.[10][11][12][13] Enzymes that are important in detoxification metabolism include cytochrome P450 oxidases,[14] UDP-glucuronosyltransferases,[15] and glutathione S-transferases.[16] These processes are particularly well-studied as part of drug metabolism, as they influence the pharmacokinetics of a drug in the body.[17][18][19]

Alternative medicine

Certain approaches in alternative medicine claim to remove “toxins” from the body through herbal, electrical or electromagnetic treatments. These toxins are undefined and have no scientific basis,[6] making the validity of such techniques questionable. There is little evidence for toxic accumulation in these cases,[6] as the liver and kidneys automatically detoxify and excrete many toxic materials including metabolic wastes. Under this theory if toxins are too rapidly released without being safely eliminated (such as metabolizing fat that stores toxins) they can damage the body and cause malaise. Therapies include contrast showers, detoxification foot pads, oil pulling, Gerson therapy, snake-stones, body cleansing, Scientology‘s Purification Rundown, water fasting, and metabolic therapy.[20]
