Beer's Impact: Understanding Alcohol's Effect On Your Body

Alcohol beer, even in moderation, can have a significant impact on your body and health. While beer is often seen as a more harmless alternative to other alcoholic drinks due to its typically lower alcohol content, drinking it can still take a toll on your health in the short and long term.

Beer, like other alcoholic drinks, can affect your brain so that your reflexes are slowed down, and your balance, memory and sleep may be impaired. It can also change the way your brain looks and works, impacting your mood and behaviour and making it harder to think clearly and move with coordination.

Drinking beer can also lead to weight gain as your body prioritises breaking down alcohol over burning fat. It can also cause digestive issues, including abdominal pain, bloating and diarrhoea, and disrupt your gut microbiome, allowing bad bacteria to grow.

Beer can also negatively impact your heart, liver and pancreas, and weaken your immune system, making you more susceptible to diseases like pneumonia and tuberculosis. It can also increase your risk of developing several types of cancer, including mouth, throat, breast, oesophageal, liver and colorectal cancer.

Beer can affect your sleep

While drinking beer may help you feel relaxed and even aid you in falling asleep, it can also negatively impact your sleep quality.

• Beer, like other alcoholic drinks, can slow down your reflexes, impair your balance, memory, and sleep.
• Alcohol affects your brain's communication pathways and its ability to process information.
• It can disrupt your sleep cycle, causing you to spend less time in the important REM stage of sleep, which is crucial for learning and memory consolidation.
• Drinking before bed can lead to frequent wakings and overall low-quality sleep.
• It can worsen pre-existing sleep disorders such as snoring and sleep apnea, and even contribute to the development of insomnia.
• It can interfere with your circadian rhythm, making you feel sleepy when you want to be awake and alert when you want to sleep.
• The diuretic effect of alcohol can cause you to wake up multiple times during the night to use the bathroom, disrupting your sleep.

How to minimise the impact:

• Avoid drinking alcohol close to bedtime. It is recommended to stop consuming alcohol at least three hours before bedtime.
• Limit your alcohol intake and follow the UK Chief Medical Officers' low-risk drinking guidelines.
• Alternate alcoholic drinks with water or soft drinks to stay hydrated and reduce the impact of dehydration on your sleep.
• If you are experiencing insomnia or other sleep issues, seek professional help.

Beer can cause digestive issues

When consumed in large amounts, alcohol can cause intestinal inflammation and issues within the gastrointestinal tract and the liver. It can negatively alter the bacteria in your gut and permeate the lining of the intestine (leaky gut syndrome), making the body even more susceptible to alcohol-related diseases, including alcoholic fatty liver disease.

The liver's job is to filter circulating blood and destroy toxic substances, including alcohol. The liver can handle a certain amount of alcohol, but as a person continues to drink, it can become stressed to the point of causing permanent damage.

Beer can increase your risk of chronic diseases

Excessive alcohol consumption can also lead to cardiovascular issues. Heavy drinking over a long period or excessive drinking on a single occasion can damage the heart, causing problems such as cardiomyopathy, arrhythmias, and high blood pressure.

The liver is another organ that is vulnerable to the harmful effects of alcohol. Heavy drinking can lead to liver inflammation and problems such as steatosis, or fatty liver. Alcohol consumption can also cause intestinal inflammation and issues within the gastrointestinal tract and the liver, potentially leading to alcoholic fatty liver disease.

Additionally, alcohol consumption can negatively impact blood sugar regulation and increase the risk of diabetes. It can affect the pancreas, which helps regulate insulin and respond to glucose. Alcohol abuse can lead to low blood sugar (hypoglycemia) or high blood sugar (hyperglycemia) and increase the risk of diabetes-related complications.

While moderate alcohol consumption is often associated with improved heart health, recent research suggests that these benefits may be overestimated and do not outweigh the potential risks. Therefore, it is important to consume alcohol in moderation and follow guidelines that recommend limiting daily intake to two drinks or less for men and one drink or less for women.

Beer can affect your weight

Secondly, beer can affect your appetite and digestion. It can irritate the small intestine and colon, affecting the speed at which food moves through your body, and potentially causing abdominal pain, bloating and diarrhoea.

Thirdly, beer can contribute to dehydration, which is a factor in weight gain. However, one study found that moderate consumption of low-alcoholic beers did not have as strong a diuretic effect as other alcoholic drinks.

Finally, beer may be linked to an increased risk of developing diabetes. One study found that men who drank high amounts of beer had a higher risk of developing pre-diabetes and type 2 diabetes. However, moderate consumption of beer was not found to increase body weight in obese individuals in another study.

Overall, while beer can affect your weight, the specific impact will depend on various factors, including the amount and frequency of consumption, as well as individual characteristics such as gender and existing health conditions.

Beer can weaken your immune system

Drinking excessively can lead to a decrease in a specific type of white blood cell called lymphocytes, which are crucial for fighting off infectious diseases. This leaves heavy drinkers more vulnerable to illnesses and makes it harder for their bodies to heal.

Additionally, alcohol consumption can cause an inflammatory response from your immune system, further compromising your body's ability to defend against pathogens. This inflammatory response is one of the factors contributing to the unpleasant symptoms of a hangover.

The negative impact of alcohol on the immune system is dose-dependent, with heavier and more frequent drinking leading to more severe immunosuppression. Therefore, it is essential to drink in moderation to lower the risk of immune system dysfunction. According to the Centers for Disease Control and Prevention (CDC), moderate drinking is defined as one or fewer drinks per day for women and two or fewer drinks per day for men.
