The first thing that needs to be said about detoxing from alcohol at home is that this is absolutely unsafe and potentially fatal. Alcohol is one of the few drug withdrawal syndromes which can kill. The neurotransmitter imbalances that the brain experiences can lead to life-threatening issues which include stroke, heart attack, brain damage, and death. In addition to the serious health risks, attempting to detox at home will also result in far more discomfort. There are many medications that are commonly used during medical detox that isn’t easily available outside of a facility. These medications can decrease the discomfort experienced, as well as reduce the dangers and risks greatly. Finally, if any complications were to occur, these detox facilities are properly equipped to deal with them in the manner possible.

Immediate Dangers of Self-Detox from Alcohol

When someone who has developed a physical dependence on alcohol stops drinking suddenly, the body and brain are under extreme stress due to chemical imbalances which result in a wide range of physical symptoms. Even if these do not result in death, they can easily lead to situations where someone is unable to get help or is so confused and disoriented that they make a fatal mistake or injure others.

Some of the greatest and most common dangers of detoxing from alcohol at home include:

  • Heart Issues: Due to glutamate, norepinephrine, and GABA imbalances, the brain sends uncoordinated and erratic signals to the heart. This can lead to cardiac arrest, dangerous cardiac arrhythmias, and wild changes in blood pressure. Treatment can manage the symptoms and minimize the danger, but this requires medical help.
  • Stroke: Due to changes in blood pressure as well as blood vessel decay due to chronic alcohol use, the risks of stroke are greatly heightened during acute withdrawal. Risks can be monitored and managed by medical professionals, but left untreated it can be fatal.
  • Dehydration: Coupled with the other issues which may arise, dehydration can greatly increase the chances of a negative outcome. Most heavy drinkers are fairly dehydrated as is, but add in the constant heavy sweating from detox and the danger is elevated. This can result in severe electrolyte imbalances which can present unique risks.
  • Seizure: Due to neurotransmitter imbalances, seizures are a common symptom of acute withdrawal. If severe enough, these can escalate to status epilepticus which is indicative of brain damage.
  • Delirium Tremens: A very severe potential symptom that occurs in a minority of drinkers, DT’s are characterized by confusion, disorientation, intense hallucinations and delusions, disorganized or clouded thinking, and vital sign hyperactivity. Unstable heart rate and blood pressure will change even more wildly and thus the risk of stroke or heart complications increases during DTs. Left untreated, it has a 35% mortality rate. This means that over 1 in 3 people who go through delirium tremens without treatment will not survive.

Long Term Risks of Detoxing At Home

The greatest risk of self-detox, other than death of course, is the issue of relapse. While studies vary in the exact numbers, it is certain that the relapse rates are much higher for those who detox from alcohol at home. Having access to support from medical, psychology, and psychiatry professionals will substantially increase the chances of successful recovery. A detox program is often the first introduction to recovery and can help them safely and comfortably endure withdrawal, and continue long term treatment.

There are also unique long term risks associated with detoxing from alcohol at home. These are mostly caused by the actual withdrawal process itself and are made much more severe by going “cold turkey” without medications to manage the symptoms.

Self-detoxing from alcohol increases the level of risks associated with each of the following:

  • Brain Damage: Due to seizures and the risk of delirium tremens, it is possible for hypoxic brain damage to result from detoxing at home The imbalances in GABA and glutamate, in particular, can also lead to glutamate excitotoxicity in the brain which will have long-lasting repercussions and could even produce permanent anxiety or depression disorders.
  • Kindling Process: While the exact mechanisms for this are unclear, it is known that repeated withdrawal produces more severe symptoms the next time. This risk may be minimized with medications, but self-detoxing is certain to make the next experience much worse.
  • Heart Disease: Due to chronic alcohol use the muscles of the heart become weak and thin. During the wild changes in heart rate and blood pressure during withdrawal, this puts immense strain on the heart, weakening it even further. Risks for heart disease among alcoholics are much higher than the rest of the population already, and the added stress increases this risk even further. Alcoholic cardiomyopathy is one of the most common forms of alcohol-induced heart disease.
  • Metabolic Disorders: Both diabetes and pancreatitis are common among alcoholics, and the metabolic damage done through withdrawal makes this risk greater. Going through withdrawal at home produces changes and abnormalities in blood sugar, brain glucose metabolism, and insulin production. These will add to the already high risk of developing a metabolic disorder later in life.

An effective simile for the effects self-detox from alcohol has on the brain is to think of the brain as a car with a manual transmission. Not everyone knows how to drive a manual, but most people know the horrible sound they make when it’s not done right. Normally, neurotransmitters act like the clutch and allow thoughts, feelings, and vital processes to shift smoothly. When experiencing withdrawal, the clutch doesn’t always get pushed in and the gears grind. The more this happens, the worse the gears get, and the easier it is for them to grind in the first place.

This also has negative effects on memory, cognition, and perception as well. Reduced mental capacity and an increase in dementia-like symptoms are very common among chronic alcoholics. These risks are elevated when undergoing alcohol withdrawal at home.

The Safe Option

Having access to support from medically trained recovery professionals will substantially increase the chances of successful alcoholism treatment. Entering an alcohol detox center can provide access to resources that may not be available otherwise. This can help someone safely and comfortably endure withdrawal, and continue long term treatment.
