Beer Overdose: Harmful Effects On Your Body

Drinking too much beer can have serious consequences for your health. While drinking a small amount of beer may be associated with some health benefits, heavy or binge drinking is linked to a range of harmful side effects.

Drinking too much beer can cause both short-term and long-term effects on the body. Temporary effects include feelings of relaxation, drowsiness, and euphoria, as well as slowed or slurred speech, changes in perception, and loss of coordination. However, these effects can also lead to accidents, injuries, and impulsive decisions.

Long-term effects of drinking too much beer can include persistent changes in mood, insomnia, a weakened immune system, and an increased risk of developing heart-related health issues, liver disease, pancreatitis, and certain types of cancer. Alcohol can also affect the central nervous system, causing damage that results in numbness and tingling in the hands and feet.

To reduce the risk of negative health consequences, it is recommended to limit beer intake to no more than one standard drink per day for women and two for men.

May cause digestive issues and abdominal pain

Drinking beer can have several effects on the digestive system. Alcohol is first broken down in the stomach, promoting an increase in digestive juices. It also irritates the small intestine and colon, where it is further broken down and absorbed. It can also affect the normal speed at which food moves through the digestive tract, which may result in abdominal pain, bloating, and diarrhoea.

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 more susceptible to alcohol-related diseases, including alcoholic fatty liver disease.

According to the National Institute on Alcohol Abuse and Alcoholism, alcohol causes the pancreas to produce toxic substances that can eventually lead to pancreatitis, a dangerous inflammation of the pancreas that causes swelling and pain (which may spread) and impairs its ability to produce enzymes and hormones for proper digestion. Pancreatitis can become a long-term condition and cause serious complications.

Drinking heavily can also lead to a feeling of fullness in the abdomen, diarrhoea or painful stools, and ulcers or haemorrhoids (due to dehydration and constipation). Ulcers can cause dangerous internal bleeding, which can sometimes be fatal without prompt diagnosis and treatment.

Can increase the risk of cancer

Drinking beer, like any other alcoholic beverage, can increase the risk of cancer. Alcohol is a known human carcinogen, and the more alcohol one consumes, the higher the risk of developing an alcohol-associated cancer. Even light drinking (up to one drink per day) and binge drinking are associated with a modest increase in cancer risk.

Alcohol use has been linked to cancers of the mouth, throat, voice box, and esophagus. The combination of smoking and drinking increases the risk of these cancers significantly more than smoking or drinking alone. Alcohol acts as an irritant in the mouth and throat, damaging cells and interfering with their ability to repair themselves, which can lead to DNA changes that increase the risk of cancer.

Heavy alcohol consumption is associated with an increased risk of liver cancer, possibly due to the inflammation and scarring it causes in the liver. Alcohol use is also linked to a higher risk of breast cancer, as it can raise estrogen levels in the body, and colorectal cancer, although the evidence for the latter is generally stronger in men than in women.

In addition to increasing the risk of these specific cancers, alcohol consumption is associated with increased risks of melanoma, prostate cancer, and pancreatic cancer. The risk of developing cancer is higher the more alcohol one consumes, and drinking less alcohol can reduce this risk.

Can negatively impact mental health

Drinking too much beer can negatively impact your mental health in several ways. Firstly, alcohol interferes with the brain's communication pathways, affecting the way the brain looks and works. This can change your mood and behaviour, and make it harder to think clearly and move with coordination. People with pre-existing mental health conditions such as anxiety and depression may turn to alcohol to help ease their symptoms, but excessive alcohol use can worsen these conditions over time. Alcohol can also induce anxiety and depression in people who did not previously experience these conditions.

Drinking too much beer can also lead to alcohol dependence, which can further negatively impact your mental health. If you are alcohol-dependent and suddenly stop drinking, you may experience withdrawal symptoms such as hallucinations. To get rid of these symptoms, you might try to drink more alcohol, but this can lead to a vicious cycle and even more problems. Excessive drinking can also get in the way of other activities, harm your relationships, and lower your self-esteem, all of which can negatively affect your mental health.

Long-term alcohol misuse and dependence can cause permanent changes to the brain, such as problems with understanding, remembering, and thinking logically. This is sometimes called alcohol-related brain damage. Additionally, alcohol dependence can lead to social problems such as homelessness, joblessness, divorce, and domestic abuse, all of which can have a detrimental effect on mental health.

Can cause liver disease

Drinking too much beer can cause liver disease, which is damage to the liver and its function due to alcohol abuse. Alcoholic liver disease (ALD) is very common in the UK, and the number of people with the condition has been increasing over the last few decades due to rising levels of alcohol misuse. ALD refers to liver damage caused by excess alcohol intake and there are several stages of severity, with symptoms ranging from mild to life-threatening.

Alcoholic Fatty Liver Disease

Drinking a large amount of alcohol, even for just a few days, can lead to a build-up of fats in the liver, known as alcoholic fatty liver disease. This is the first stage of ALD and can be reversible if you stop drinking alcohol for at least 2 weeks. Fatty liver disease rarely causes any symptoms, but it is an important warning sign that you are drinking at a harmful level.

Alcoholic Hepatitis

Alcoholic hepatitis is a potentially serious condition that can be caused by alcohol misuse over a longer period. It can also occur if you drink a large amount of alcohol in a short period of time (binge drinking). The liver damage associated with mild alcoholic hepatitis is usually reversible if you stop drinking permanently. However, severe alcoholic hepatitis is a serious and life-threatening illness that can lead to death.

Cirrhosis

Cirrhosis is a stage of ALD where the liver has become significantly scarred. It is generally not reversible, but stopping drinking alcohol immediately can prevent further damage and significantly increase your life expectancy. A person who has alcohol-related cirrhosis and doesn’t stop drinking has a less than 50% chance of living for at least 5 more years.

Treatment

There is currently no specific medical treatment for ALD. The main treatment is to stop drinking, preferably for the rest of your life. This reduces the risk of further damage to your liver and gives it the best chance of recovering. Stopping drinking can be very difficult, especially as an estimated 70% of people with ALD have an alcohol dependency problem. Nevertheless, if you have alcohol-related cirrhosis or alcoholic hepatitis and don’t stop drinking, no medical or surgical treatment can prevent liver failure.

Can weaken the immune system

Drinking too much beer can weaken your immune system, making it easier for diseases to target your body. Chronic drinkers are more likely to contract diseases like pneumonia and tuberculosis than those who do not drink excessively. Even up to 24 hours after getting drunk, your body's ability to ward off infections is slowed down.

The link between heavy drinking and a weakened immune system is well-established. Research has found that alcohol misuse is strongly linked to self-harm, including suicide. This is because alcohol can affect your central nervous system, reducing communication between your brain and body and impairing your coordination and ability to think clearly. This can lead to accidents, injuries, and impulsive decisions that put you at risk.

Drinking too much beer can also cause inflammation of the pancreas, resulting in pancreatitis. This can activate the release of pancreatic digestive enzymes and cause abdominal pain. Pancreatitis can become a long-term condition and lead to serious complications.

Additionally, alcohol interferes with the liver's ability to break down and remove toxins from the body. This can increase your risk of alcohol-related liver diseases, such as cirrhosis, which is characterised by scarring of the liver. A damaged liver may also affect your blood sugar levels, leading to complications related to diabetes.

Overall, drinking too much beer can have serious negative consequences for your immune system and overall health. It is important to drink in moderation and seek support if you are struggling to cut down.
