Beer Overindulgence: When Does It Become A Problem?

Drinking too much beer can have serious health consequences, and it's important to understand what defines drinking too much. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), drinking levels and patterns can be classified as moderate, binge, or heavy drinking. Binge drinking is defined as consuming enough alcohol to bring blood alcohol concentration (BAC) to 0.08% or higher, which typically occurs when a man consumes 5 or more drinks or a woman has 4 or more drinks within about 2 hours. Heavy drinking is defined as consuming 5 or more drinks per day for men or 4 or more drinks per day for women. These drinking patterns can lead to acute and chronic health problems, including liver disease, alcohol use disorder (AUD), and social issues such as relationship problems. It's worth noting that there is no safe drinking level, and the less alcohol consumed, the lower the health risks.

Health risks of drinking too much beer

Drinking too much beer can have several negative health consequences. Firstly, beer contains empty calories, which can contribute to weight gain and obesity, leading to various health issues. Excessive beer consumption can also increase the risk of heart disease, with studies suggesting a link between excessive drinking and hypertension (high blood pressure). Beer, like other alcoholic drinks, can also negatively impact mental health and has been linked to self-harm and suicide.

In addition to the immediate health risks, excessive beer drinking can lead to long-term health problems. Consuming three or more drinks per day is associated with a higher risk of health issues, including hemorrhagic stroke (caused by excess bleeding in the brain), a weakened immune system, and learning and memory problems. Furthermore, excessive beer consumption can lead to alcohol dependency and alcohol use disorders.

According to the NHS, drinking more than 14 units of alcohol per week is considered risky and can damage your health. This guideline applies to both men and women. To put this into perspective, a single drink is typically defined as 12 ounces of regular beer, and drinking more than two drinks per day for men or one drink per day for women is considered excessive.

It is important to note that there is no safe drinking level, and the less you drink, the lower the health risks. The effects of alcohol consumption can vary depending on factors such as body weight, metabolism, and other individual characteristics. Therefore, it is always advisable to drink in moderation and consult a doctor or healthcare professional for personalized advice.

Binge drinking

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the Substance Abuse and Mental Health Services Administration (SAMHSA) in the United States have conducted surveys and provided definitions for binge drinking. According to the NIAAA, binge drinking is a pattern of alcohol consumption that results in a BAC of 0.08% or higher. This typically occurs when an adult woman consumes four or more drinks or an adult man consumes five or more drinks within about two hours. However, it is important to note that it takes fewer drinks to reach this BAC level in youths, with girls needing only three drinks and boys requiring three to five drinks, depending on their age and size.

The SAMHSA, which conducts the annual National Survey on Drug Use and Health (NSDUH), defines binge drinking as consuming four or more alcoholic drinks for females or five or more drinks for males on the same occasion, such as during a single event or within a couple of hours of each other, on at least one day in the past month.

Heavy drinking

The negative consequences of heavy drinking can be both acute and chronic. Acute harms include falls, medication interactions, misjudging risky situations, and losing self-control, which may lead to risky behaviours such as unprotected sex or violence. Chronic consequences, on the other hand, develop over time and include an increased risk of liver disease, heart disease, and various types of cancer, including mouth, throat, and breast cancer. Heavy drinking can also lead to social, emotional, and mental health challenges, including relationship problems, depression, anxiety, and memory issues.

It is important to note that there is no safe drinking level, and the less alcohol consumed, the lower the health risks. To minimise alcohol-related risks, men should not drink more than 14 units of alcohol per week on a regular basis, while women should not exceed 7 units per week. Additionally, it is recommended to spread drinking over three or more days if consuming the weekly maximum and to have several drink-free days each week.

Alcohol misuse

The risks of alcohol misuse include both short-term and long-term effects. Short-term risks include accidents, injuries, violent behaviour, unprotected sex, and alcohol poisoning. Long-term risks include damage to the brain, liver, and pancreas, as well as an increased risk of certain types of cancer, such as mouth, throat, breast, head and neck, and oesophageal cancer. Alcohol misuse can also lead to social problems, such as unemployment, divorce, domestic abuse, and homelessness.

It's important to note that there is no safe drinking level, and the less you drink, the lower the health risks. To keep health risks from alcohol low, it is recommended that both men and women drink no more than 14 units of alcohol per week and spread their drinking over 3 or more days. If you are pregnant or planning to become pregnant, it is safest to avoid alcohol completely to minimise risks to the baby.

If you feel that you or someone you know may be misusing alcohol, it is important to seek help. This could include talking to a healthcare professional, such as a GP, or reaching out to support groups and charities that specialise in alcohol misuse.

Alcohol use disorder (AUD)

Drinking too much beer can be defined in several ways. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) states that drinking more than 1 drink a day for women and 2 drinks a day for men is not recommended. Drinking more than this amount is considered heavy drinking, which increases the risk of alcohol-related problems such as liver disease and alcohol use disorder (AUD).

AUD is a medical condition characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. It is considered a brain disorder and can be mild, moderate, or severe. Lasting changes in the brain caused by alcohol misuse perpetuate AUD and make individuals vulnerable to relapse. According to the 2023 National Survey on Drug Use and Health, about 18 million adult Americans or 10.9% of adults aged 18 and older had AUD in the past year.

Risk Factors for AUD

A person’s risk for developing AUD depends on how much, how often, and how quickly they consume alcohol. Binge drinking and heavy alcohol use are forms of alcohol misuse that increase the risk of AUD. Other risk factors include:

• Drinking at an early age: Those who begin drinking before age 15 are more than three times as likely to develop AUD compared to those who start drinking at age 21 or older.
• Genetics and family history: Genetics play a role, with hereditability accounting for approximately 60% of the risk. Parents’ drinking patterns may also influence their children's likelihood of developing AUD.
• Mental health conditions and trauma: Psychiatric conditions such as depression, PTSD, and ADHD are associated with an increased risk of AUD. People with a history of childhood trauma are also more vulnerable to developing AUD.

Symptoms of AUD

Health care professionals use criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) to assess and determine the severity of AUD. Mild AUD is defined as having 2-3 symptoms, moderate AUD as having 4-5 symptoms, and severe AUD as having 6 or more symptoms. Some of the symptoms of AUD include:

• Drinking more or longer than intended
• Unsuccessful attempts to cut down or stop drinking
• Spending a lot of time drinking or recovering from drinking
• Experiencing cravings or a strong need to drink
• Drinking interferes with family life, work, or school
• Continuing to drink despite problems with family or friends
• Giving up activities in order to drink
• Engaging in dangerous behaviours while drinking, such as drunk driving or unsafe sex
• Continuing to drink despite negative consequences, including feelings of depression or anxiety
• Developing tolerance, needing to drink more to feel the effects
• Experiencing withdrawal symptoms when not drinking, such as trouble sleeping, shakiness, or nausea

Treatment for AUD

There are several evidence-based treatment approaches available for AUD, including behavioural therapies, mutual-support groups, and medications. Three medications are currently approved by the U.S. Food and Drug Administration to help reduce drinking and prevent relapse: naltrexone, acamprosate, and disulfiram. These medications can be used alone or in combination with behavioural treatments or mutual-support groups.

People with severe AUD may need medical help to manage alcohol withdrawal symptoms if they stop drinking. Alcohol withdrawal can be life-threatening and should be managed by a doctor who can prescribe medications to address the symptoms.
