Alcohol use disorder, commonly referred to as alcoholism, is characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. It’s a complex condition that varies in severity, ranging from mild to severe. Many factors influence when alcohol use becomes problematic. There is no definitive threshold for how many drinks per week makes someone an alcoholic. However, health organizations provide guidelines on low-risk alcohol consumption limits to avoid potential health and safety issues. Exceeding these limits regularly may indicate the need to re-evaluate drinking habits.
What is Considered Moderate, Heavy, and Binge Drinking?
The 2020-2025 Dietary Guidelines for Americans define moderate, heavy, and binge drinking as:
- Moderate: Up to 1 drink per day for women and up to 2 drinks per day for men.
- Heavy: More than 3 drinks on any day or more than 7 per week for women and more than 4 drinks on any day or more than 14 per week for men.
- Binge: 4 or more drinks within 2 hours for women and 5 or more drinks within 2 hours for men.
One standard drink is defined as:
- 12 ounces of regular beer (about 5% alcohol)
- 5 ounces of wine (about 12% alcohol)
- 1.5 ounces of 80-proof distilled spirits (about 40% alcohol)
Drinking at moderate levels, if at all, is considered low-risk for developing alcohol use disorder. Heavy and binge drinking increase risks for health and safety issues. However, even those who drink within moderate limits can develop alcoholism under certain circumstances. Heredity, mental health, and environment all play a role.
Signs of Alcoholism
There is no specific number of drinks per week that indicates alcoholism. However, regularly exceeding moderate drinking limits and displaying other symptoms could signify alcohol use disorder. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), signs of alcoholism include:
- Drinking more or longer than intended
- Persistent desire to cut down or unsuccessful efforts to control use
- Great deal of time spent obtaining, using, or recovering from alcohol
- Craving or strong urge to use alcohol
- Failure to fulfill major role obligations due to repeated alcohol use
- Continued use despite negative interpersonal or social consequences
- Giving up or reducing social, occupational, or recreational activities due to alcohol use
- Recurrent alcohol use in physically hazardous situations
- Continued alcohol use despite physical or psychological problems caused or worsened by drinking
- Tolerance (needing more alcohol to get desired effect)
- Withdrawal symptoms when stopping or cutting back on alcohol
The more symptoms present, the more severe the alcohol use disorder. Even a mild disorder involving 2 or 3 symptoms can negatively impact health and quality of life if alcohol use continues.
Health Risks of Excessive Alcohol Use
Drinking too much over time can increase the risk of many health problems:
- Liver diseases – fatty liver, alcoholic hepatitis, cirrhosis
- Digestive problems – inflammation, ulcers, acid reflux
- Diabetes
- Various cancers – breast, colorectal, liver, esophageal, throat
- Weakened immune system
- Brain damage and cognitive deficits
- Heart disease
- High blood pressure
- Stroke
- Prenatal alcohol exposure risks in pregnancy
- Bone loss and fractures
- Neurological disorders – neuropathy, dementia, depression
- Sexual dysfunction
- Sleep disorders
Those with alcoholism are also more prone to accidents, injuries, suicides, and family/social issues. The risk of these consequences increases with the amount consumed. Even moderate drinking may pose some health risks.
Genetic Predisposition to Alcoholism
Genetics account for about half the risk of alcohol use disorder. Certain variations in genes involved in metabolizing alcohol and brain signaling pathways modify addiction vulnerability. Someone with no affected relatives has a 7-10% chance of developing alcoholism. But with an alcoholic parent or sibling, the risk is 2-3 times higher. The heritability comes from complex interactions among many genes and biological pathways over time. Just having the genetic susceptibility does not guarantee alcoholism will develop. Environmental influences and individual characteristics are also important factors. But genetics may partially explain why some become addicted to alcohol after only a few drinks per week, while others regularly have more without becoming dependent.
Co-Occurring Mental Health Disorders
Many people with alcoholism also have co-occurring mental health disorders, especially:
- Anxiety
- Depression
- Bipolar disorder
- Schizophrenia
- Post-traumatic stress disorder (PTSD)
It’s unclear whether mental health problems increase addiction risk, or vice versa. Either way, the combined effects exacerbate alcoholism severity and make treatment more complex. Those with both alcoholism and mental health disorders tend to start heavy drinking earlier in life and have worse dependence symptoms. Even moderate drinking may be risky for those with specific disorders. This interconnection needs to be addressed for successful recovery.
Environmental Factors
Aspects of a person’s environment also affect their chances of developing alcoholism:
- Stress – Unmanaged stress often leads to unhealthy coping behaviors, including alcohol misuse.
- Influence of family and peers – Having heavy drinkers in one’s social circle provides modeling of and access to excessive drinking.
- Trauma history – Those exposed to violence, abuse, neglect, discrimination, etc. have a higher addiction vulnerability.
- Low income or education level – This group faces more stressors and fewer resources to cope without substances.
- Easy access to alcohol – Omnipresent liquor stores, bars, ads normalize drinking and enable unhealthy consumption.
- Lack of family or social support – Isolation and relationship issues promote problematic drinking.
Improving these environmental conditions could lower alcoholism risks, even for those genetically predisposed. Surrounding oneself with a strong support network and avoiding triggers reduces dependence likelihood.
Cognitive Behavioral Therapy for Alcoholism
Cognitive behavioral therapy (CBT) is an effective treatment for alcohol use disorder. This psychotherapeutic approach helps people recognize problematic thought and behavior patterns stemming from distorted beliefs. CBT aims to change these thought processes to improve coping abilities and reduce harmful drinking behaviors.
Some common CBT techniques for alcoholism include:
- Identifying and challenging irrational thoughts about needing alcohol.
- Avoiding emotional and environmental triggers for cravings.
- Finding healthy pleasurable activities to substitute for drinking.
- Controlling impulses to drink through urge surfing and distraction methods.
- Setting goals like days sober or drinks limits then monitoring progress.
- Identifying cognitive distortions that lead to drinking and altering them.
- Learning to tolerate distress and discomfort without alcohol.
- Establishing a crisis plan for potential relapses.
CBT provides long-lasting skills to manage alcoholism and maintain sobriety. It is often combined with medications and support groups.
Alcoholics Anonymous (AA)
Alcoholics Anonymous (AA) is one of the most widely used mutual support groups for alcoholism recovery. AA applies a 12-step program emphasizing peer support, sober living, and spirituality. Core AA principles include:
- Admitting powerlessness over alcohol and inability to manage life.
- Coming to believe in a higher power who can restore sanity.
- Examining past errors and making amends.
- Regularly taking a moral inventory.
- Praying and meditating for knowledge of God’s will.
- Becoming willing and ready to remove character defects.
Members work through the steps with sponsors who act as mentors. AA provides an internationally accessible free support network. However, it’s not scientifically proven more effective than clinical treatments. AA helps some people achieve years of sobriety, while others dislike its spiritual emphasis. It should complement professional treatment.
Effects of Abstinence on the Brain
Abstinence from alcohol over weeks to months gradually reverses brain changes caused by heavy drinking. With sustained sobriety, imaging shows the brain regrows nerve fibers and repairs circuits involved in learning, mood, and impulse control. Cognitive deficits also show improvement:
- Decision-making and problem-solving ability improve within a month.
- Verbal fluency, working memory, and sustained focus improve within 6 months.
- Impulsiveness declines around 6-12 months of abstinence.
- Processing speed and visuospatial functioning may take over a year to fully recover.
However, the longer and heavier someone drank, the longer full brain recovery takes. Some subtle deficits persist even after years abstinent if there was prolonged alcohol abuse. But abstinence at any point lessens cumulative damage. For optimal cognitive regeneration, combined addiction treatment with aerobic exercise and a healthy diet is recommended.
Conclusion
There is no definitive amount of alcohol consumption that indicates alcoholism. Binge and heavy drinking raise risks for developing dependence and health problems. But even those who drink moderately could meet diagnostic criteria for alcohol use disorder by displaying addiction behaviors and harmful consequences. The path to alcoholism depends on complex interactions of genetic susceptibility, mental health, and environment over time. Addressing these root causes through treatment like CBT, support groups, lifestyle changes, and abstinence can overcome alcoholism regardless of specific drinking quantities. Sustained sobriety allows brains altered by alcoholism to heal and executive functioning to improve.
