Alcoholism is a significant problem among doctors, with a higher prevalence rate than in the general population. This can lead to medical errors and affect a doctor's performance, especially in the case of surgeons. It is important to understand how long alcohol stays in the system, as this can impact a doctor's ability to perform their duties safely and effectively. The length of time alcohol remains in the system varies depending on factors such as medications, sex, age, and body size. While coffee or energy drinks might make one feel less intoxicated, they do not speed up the elimination process. Treatment for alcohol use disorder includes therapy, support groups, and medication, and doctors play a crucial role in helping patients manage their alcohol consumption and related issues.

Alcohol detection in the body
Alcohol is a central nervous system depressant that affects every organ in the body. It is predominantly broken down by the liver, but some people have stomach enzymes (alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH)) that help to break down alcohol before it reaches the bloodstream. Women tend to have lower levels of ADH than men, and people who drink regularly have lower ADH levels than those who rarely or never drink.
The length of time alcohol remains in the body depends on various factors, including medications, sex, age, body size, genetics, how much alcohol was consumed, and the amount of food consumed with the alcohol. In most cases, alcohol can be detected in the body for 6–72 hours, but this varies depending on the detection test used. Blood alcohol content (BAC) is a measure of the amount of alcohol in the bloodstream, expressed as a percentage. BAC levels can range from 0% to over 0.4%. At a BAC of 0.30% to 0.40%, a person will likely have alcohol poisoning, a potentially life-threatening condition.
Alcohol can be detected in the breath for 12 to 24 hours, in urine for 12 to 130 hours (up to 72 or more hours after heavier use), in saliva for up to 12 hours, and in hair for up to 90 days. The half-life of alcohol is between 4 and 5 hours, and it takes about 5 half-lives for the body to clear all the alcohol, which is about 25 hours. However, there is no set timeframe for how long alcohol stays in the system.
Diagnostic criteria for alcohol use disorder (AUD) vary, but the most widely used criteria are found in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Laboratory tests for acute alcohol ingestion include ethanol, ethyl glucuronide (EtG), and ethyl sulfate (EtS) tests. Carbohydrate-deficient transferrin (CDT) and phosphatidylethanol (PEth) are useful markers for monitoring abstinence after long-term use. Oral fluid, urine, blood, hair, and sweat are all specimen types used to detect alcohol exposure.

The role of doctors with alcohol issues
Alcohol use disorder (AUD) or alcoholism is a common medical condition that affects millions of people worldwide. It can have severe physical and psychological consequences if left untreated. People with AUD experience changes in their mood and behaviour, craving alcohol, and continuing to drink despite the negative impact on their relationships. They may also drink more than intended and spend a lot of time recovering from hangovers. AUD can lead to serious medical issues such as seizures and hallucinations during withdrawal and increase the risk of developing liver cirrhosis and cancer.
Doctors play a crucial role in treating AUD. Primary care physicians are recommended to screen all adult patients for alcohol use at least annually and provide timely interventions. They can offer brief interventions such as counselling and education to help patients understand their drinking behaviours and manage cravings. For severe cases, patients may be referred to specialised treatment programs, including residential or outpatient centres offering intensive counselling, therapy, and medication-assisted treatment.
However, stigma, lack of access to specialised care, inadequate screening, and discrimination in healthcare settings can prevent individuals with AUD from seeking treatment. It is important for doctors to address these barriers by educating themselves about AUD, treating patients with empathy and respect, and integrating alcoholism treatment into primary care to improve patient outcomes and reduce healthcare costs.
Additionally, doctors themselves may struggle with AUD, with higher prevalence rates compared to the general population. During the COVID-19 pandemic, alcohol consumption among physicians in quarantine increased, with many drinking more due to anxiety and hopelessness. Surgeons with alcohol dependence are more likely to report major medical errors, and their performance can be negatively impacted even by low amounts of alcohol consumption. Statutory medical governing bodies need to enforce clear guidelines regarding alcohol consumption for on-call doctors to ensure patient safety.

Gender differences in alcohol consumption
It takes about 25 hours for the body to completely clear alcohol. The speed of elimination depends on various factors, including medications, sex, age, and body size. Studies have shown that women take longer to process alcohol than men due to lower levels of stomach enzymes that break it down.
Now, let's delve into the topic of gender differences in alcohol consumption:
There are notable gender differences in alcohol consumption patterns and related risks. While males generally consume more alcohol and engage in binge drinking more frequently than females, these gender gaps have been narrowing over time. Here are some key insights:
Historical Gender Trends:
Historically, there was a significant gender disparity in alcohol consumption, with males outpacing females by a ratio of roughly 3:1 for measures such as prevalence, frequency, and problematic drinking. However, in recent decades, these differences have diminished, and the drinking habits of males and females have become more similar.
Current Gender Trends:
- Adolescent Drinking: Among adolescents aged 12 to 17, the percentage of boys (19%) who start drinking before turning 14 is higher than that of girls (13%). However, girls who begin drinking at an early age have a shorter time frame before their first episode of binge drinking. In contrast, when drinking starts at age 15 or later, males tend to progress to binge drinking more rapidly.
- Binge Drinking: While males still binge drink more frequently overall, the number of women aged 18 and older who engage in binge drinking has been increasing at a faster rate than men. This has contributed to the narrowing gender gap.
- Driving Under the Influence (DUI): The gender gap in DUI arrests and fatalities is also narrowing. The percentage of female drivers involved in fatal crashes with a blood alcohol concentration (BAC) above the legal limit has increased slightly, while there has been a decrease among male drivers.
- Specialty and Country Variations: Studies have found gender differences in alcohol consumption within specific medical specialties and countries. For example, female surgeons are more likely to drink weekly and engage in hazardous drinking compared to other female doctors, and country-specific cultural factors also influence drinking patterns.
Biological and Psychological Factors:
Biological factors, such as lower levels of alcohol-processing enzymes in women, contribute to differences in alcohol metabolism between genders. Additionally, psychological and social risk factors play a role. For instance, heightened impulsivity, particularly during adolescence, has been linked to problematic alcohol use, and certain traits associated with impulsivity show stronger associations with alcohol consumption and problematic drinking.
Alcohol-Related Problems:
Despite consuming less alcohol overall, women tend to experience more alcohol-related problems. This suggests that gender-specific risk factors and vulnerabilities may be at play, underscoring the need for personalized prevention and treatment approaches for alcohol use disorders in both men and women.

Alcohol metabolism
The Role of the Liver and Enzymes
The liver is the main organ responsible for metabolising alcohol, specifically through the use of an enzyme called alcohol dehydrogenase (ADH). This enzyme breaks down alcohol into acetaldehyde, a highly toxic and carcinogenic compound. The acetaldehyde is then further metabolised by another enzyme, aldehyde dehydrogenase (ALDH), into acetate, a less toxic compound. Finally, the acetate is broken down into water and carbon dioxide, which can be easily eliminated from the body.
Not everyone has these enzymes, and studies have shown that women tend to have lower levels of ADH than men. Additionally, people who drink regularly also tend to have lower ADH levels. If there is insufficient ADH or ALDH, the alcohol bypasses the stomach and goes directly into the small intestine, where it enters the bloodstream and affects the brain.
Other Factors Influencing Alcohol Metabolism
Apart from the liver, small amounts of alcohol are also metabolised in other tissues, including the pancreas, brain, and gastrointestinal tract. The presence of food in the stomach can also influence the absorption of alcohol. Food can physically block alcohol from contacting the stomach lining, absorb it, or prevent it from reaching the small intestine.
Individual characteristics such as sex, body composition, and liver function also play a role in alcohol metabolism. Women tend to have higher peak blood alcohol levels per kg of body weight due to their higher percentage of body fat. Additionally, the rate of alcohol detoxification is about 0.015 g/100mL/hour, and this process cannot be sped up. However, medications and liver damage can hinder effective metabolism.
Detection of Alcohol in the Body
Alcohol can be detected in the body long after consumption. In urine, alcohol can be detected from 12 to 130 hours, and its biomarker, phosphatidylethanol (PEth), can be detected for up to 14 days. Alcohol can be traced in breath and saliva for 12 to 24 hours, and in hair for up to 90 days. The half-life of alcohol is about four to five hours, and it takes approximately five half-lives for the body to eliminate alcohol completely, which is about 25 hours.

Managing alcohol withdrawal
Alcohol withdrawal is a set of symptoms that can develop if you stop or significantly reduce your alcohol intake after long-term use. It can range from mild to severe, with the most severe cases being life-threatening. It is important to consult a healthcare professional, especially after heavy alcohol use, as withdrawal symptoms can be dangerous and even make surgery and recovery very dangerous.
Consult a healthcare professional
Speaking with a doctor or addiction specialist before detoxing is highly recommended. They can provide resources for various treatment programs and recommend treatment for alcohol use disorder (AUD). Treatment programs often involve a combination of group psychotherapy and medications.
Choose a safe environment
Detoxing in a calm and safe setting with support from trusted friends, family, or professionals is ideal. People with a history of heavy drinking or severe withdrawal symptoms should strongly consider a medically supervised detox facility or rehab center, where healthcare professionals can monitor and treat worsening symptoms.
Take it one day at a time
Breaking the detox process into small, manageable goals can help make it more achievable. Celebrating milestones, such as one day or one week without alcohol, can boost motivation and encourage a sense of progress.
Stay hydrated
Alcohol dehydrates the body, so drinking plenty of water, herbal teas, or electrolyte-rich fluids can reduce withdrawal symptoms like headaches and fatigue.
Focus on nutrition
Eating balanced meals with plenty of fruits, vegetables, whole grains, and lean proteins can support the body's recovery during detox.
It is important to note that the rate at which alcohol leaves the system can vary depending on factors such as genetics, the amount consumed, age, weight, and food intake. Most people tend to notice a reduction in withdrawal symptoms within 5 to 7 days, but it is still advisable to seek professional help to safely manage the withdrawal process.
