Alcohol and Alcoholism

Print Friendly, PDF & Email

Although, chemically, there are many types of alcohol, drinks known as alcoholic beverages contain some percentage of ethyl alcohol, or ethanol, which is produced by the fermentation of yeast, sugars, and starches.  Common alcoholic beverages include wine, beer, and distilled spirits (e.g. whiskey, brandy, rum, vodka).  For this Tox Topic, we will adopt the generally used though imprecise term, alcohol, to refer to alcoholic beverages.  Despite overwhelming scientific evidence attesting to the deleterious and potentially devastating effects of alcohol, the bottom line is that, as with virtually all other substances, the dose makes the poison.

While most people experience pleasantly relaxing and safe experiences with alcohol in moderation, very serious health effects can ensue when people drink excessively, be this at one sitting (i.e. binge drinking) or cumulatively over time.  What constitutes moderation can differ significantly according to body weight, age, gender, and genetics.  Unhealthy use of alcohol is called alcoholism or alcohol use disorder, and can range from mild to severe.  Alcohol addiction implies a physical and/or psychological dependency on the substance.  Alcoholics usually are unable to limit their drinking, feel a craving to drink, exhibit risky behavior such as driving intoxicated, develop a tolerance to alcohol resulting in the need to have greater amounts in order to feel its effects, and can experience withdrawal symptoms when not drinking.  The consequences for the drinker, his life at home and work, and for those close to him, can be serious.  Getting a mild buzz for one’s own pleasure or to smooth social interactions is one thing but abusing alcohol can lead to serious illness, even death, due to the physiological effects of the substance itself or impaired judgement, such as drinking while driving.

Precautions are also warranted for expectant mothers.  Prenatal exposure to alcohol can result to the birth defect known as fetal alcohol syndrome, affecting the brains of children and their behavior and learning.

Alcoholism treatment and recovery programs can vary greatly.  Some are faith-based approaches.  One on one professional help can work hand in hand with support groups.  Both the physical and mental health consequences of drinking need to be addressed.  It can be a long and rocky path to break the habit and relapses are not uncommon.

So, although the tipsy imbiber is often the subject of humor, alcoholism is no laughing matter.
