Alcohol Consumption: Is Regular Drinking Harmful Or Healthy?

Alcohol consumption is a common social activity, but it is important to consider the potential health risks associated with regular drinking. Excessive alcohol use can lead to immediate and long-term health issues, including an increased risk of developing several types of cancer, such as breast cancer and colorectal cancer, and causing harm to the liver, brain, heart, and pancreas. Even low levels of alcohol consumption can raise the risk of certain cancers, and there is no safe drinking level. Regular drinking can also negatively impact mental health and increase the risk of self-harm and suicide. To minimize health risks, it is recommended to limit alcohol intake, with men advised to have no more than two drinks per day and women no more than one drink per day.

Alcohol's impact on mental health

Alcohol and mental health are closely intertwined. Drinking excessively can negatively impact your mental health and well-being. Alcohol can make you lose your inhibitions, act impulsively, and increase the likelihood of actions such as self-harm or suicide. Regular heavy drinking is associated with symptoms of depression and anxiety, and can worsen pre-existing mental health issues. People with depression who stop drinking often experience an improvement in their symptoms within a few weeks, indicating that alcohol may have been a contributing factor to their mental health issues.

Alcohol can also interfere with other aspects of your life, such as relationships and self-esteem, which can further impact your mental health. Additionally, long-term heavy drinking can lead to alcohol dependence or addiction, also known as alcoholism. This can result in physical symptoms such as tolerance to alcohol, where the brain becomes less responsive to its positive effects. Withdrawal symptoms from alcohol can include nausea, vomiting, and worsened mental health. It is important to note that if you are dependent on alcohol, quitting abruptly can be unsafe, and it is recommended to consult a doctor to develop a plan to reduce alcohol consumption safely.

Alcohol use disorder (AUD) frequently co-occurs with other mental health disorders. Integrated treatment of AUD and co-occurring psychiatric disorders, such as depression, anxiety, PTSD, or sleep disorders, tends to lead to better outcomes. Interventions such as motivational enhancement therapy, cognitive-behavioral therapy (CBT), and contingency management are standard behavioral healthcare approaches for individuals with AUD.

Excessive alcohol consumption can also lead to alcohol-related brain damage (ARBD), which can cause problems with memory, understanding, and logical thinking. This is more common in women who drink more than 50 units of alcohol per week for five years or more, and men who drink more than 60 units per week over the same period.

To summarize, regular heavy drinking can negatively impact mental health, worsen existing mental health issues, and increase the risk of alcohol dependence. It is important to monitor alcohol consumption, as excessive drinking can have detrimental effects on overall well-being and brain health.

Alcohol's link to cancer

Alcohol consumption is linked to an increased risk of developing several types of cancer. The International Agency for Research on Cancer (IARC) categorises alcohol as a Group 1 carcinogen, a cancer-causing substance. This classification is based on substantial evidence that alcohol causes cancers of the oral cavity, pharynx, larynx, oesophagus, and liver.

Several mechanisms have been proposed to explain the link between alcohol and cancer. Firstly, alcohol can disrupt cell cycles, increase chronic inflammation, and damage DNA. DNA serves as the cell's "instruction manual," directing its growth and function. When DNA is damaged, cells can grow uncontrollably and turn cancerous. Alcohol consumption is also associated with increased levels of hormones like estrogen, which plays a role in the development of breast cancer.

Additionally, alcohol makes it easier for the cells in the mouth and throat to absorb carcinogens, or cancer-causing chemicals. For instance, when alcohol and tobacco are used together, alcohol enhances the absorption of carcinogens from tobacco. This can lead to an elevated risk of oral and throat cancers.

The link between alcohol consumption and cancer risk is evident in statistical data. Alcohol consumption was responsible for about 5% of the 1.8 million cancer cases diagnosed in the United States in 2019, amounting to nearly 100,000 cases. Furthermore, it contributed to about 4% of the 600,000 cancer deaths in the same year, representing approximately 25,000 deaths.

It is important to note that the risk of developing alcohol-related cancers varies based on gender and drinking patterns. For instance, women who consume one drink per day have a higher risk of breast cancer than those who drink less than once a week, and the risk increases further for heavy and binge drinkers.

Alcohol and pregnancy

Regular alcohol consumption is not advisable, and drinking alcohol while pregnant is particularly harmful. Alcohol consumed during pregnancy can cause long-term medical problems and birth defects in the baby. The alcohol travels through the mother's blood and into the baby's blood, tissues, and organs. Since alcohol breaks down much more slowly in the baby's body, the child's blood alcohol level remains high for longer than the mother's. This can cause lifelong harm to the baby.

Drinking large amounts of alcohol during pregnancy can lead to fetal alcohol syndrome, a group of defects in the baby. These defects can range from mild to severe and include facial abnormalities, as well as learning and behavioural problems. The risk of miscarriage and stillbirth also increases if the mother drinks alcohol. Even light or moderate drinking can affect the developing fetus. There is no known "safe" amount of alcohol use during pregnancy, and drinking during the first three months is considered the most harmful.

To prevent fetal alcohol syndrome and other related issues, pregnant women should avoid drinking any amount of alcohol. If a woman did not know she was pregnant and drank alcohol, she should stop drinking as soon as she learns of her pregnancy. Additionally, both men and women should reduce their alcohol consumption when trying to conceive. Studies suggest that regular alcohol consumption significantly reduces sperm quality, decreasing the chances of pregnancy and potentially causing future developmental problems for the child.

In summary, alcohol consumption during pregnancy can have severe negative consequences for both mother and child. To ensure the best possible health outcomes, it is recommended that pregnant women and those planning to become pregnant abstain from alcohol entirely.

Alcohol's effect on the liver

Alcohol is the third-leading preventable cause of death in the U.S., with 95,000 people dying each year from alcohol-related causes. Excessive alcohol use can have immediate and long-term health risks. Drinking less alcohol can improve your health and well-being.

The liver is the largest organ inside your body and has several important functions. It makes bile, a fluid that aids in food breakdown in your digestive tract. It metabolises fats, proteins, and carbohydrates, converting them into energy. It also breaks down and aids in the removal of toxins produced in your gut when you digest food, alcohol, or medication. The liver also manufactures and distributes proteins that carry out critical tasks such as fighting infections, preventing illnesses, and ensuring proper blood clotting.

Alcohol affects the liver by interfering with its normal functions. When the liver metabolises or breaks down alcohol, it produces a chemical called acetaldehyde, which is harmful to the body. This chemical damages DNA and prevents the body from repairing the damage, which is why alcohol consumption is associated with an increased risk of at least six types of cancer, including colon, liver, oesophageal, mouth, and breast cancers.

Excessive alcohol consumption can lead to the buildup of fat in the liver, a condition known as fatty liver or hepatic steatosis. Fatty liver is the earliest stage of alcohol-related liver disease and can progress to inflammation of the liver, known as alcoholic hepatitis. About one-third of heavy drinkers develop alcoholic hepatitis, which can cause symptoms such as jaundice, fever, nausea, vomiting, and abdominal pain. If left untreated, alcoholic hepatitis can lead to cirrhosis, a severe form of liver scarring where scar tissue replaces healthy liver cells, resulting in liver failure, a life-threatening condition.

It is important to note that the effects of alcohol on the liver are dose-dependent, and the risk of developing liver disease varies from individual to individual. However, even low levels of alcohol consumption (less than one drink per day) can increase the risk of certain cancers. Therefore, it is recommended to drink in moderation or abstain from alcohol to maintain optimal liver health.

Alcohol poisoning

Regular alcohol consumption is not advisable due to the associated health risks. Excessive alcohol use can lead to immediate and long-term health issues and even death. Binge drinking, heavy drinking, and any drinking during pregnancy or by people under the age of 21 are all considered excessive drinking.

Even low levels of alcohol consumption can increase the risk of certain cancers. While some past studies suggested that moderate drinking may be beneficial, these findings are highly debated and contradicted by more recent research. It is now understood that there are no health benefits to moderate drinking compared to abstaining.

The risks associated with alcohol consumption are not limited solely to the drinker but can also impact those around them. Additionally, combining alcohol with certain medications or drugs can be extremely dangerous and increase the risk of an overdose.

The amount of alcohol that can lead to poisoning varies among individuals, as age, sex, tolerance, speed of drinking, medications, and food intake all play a role. However, binge drinking and high-intensity drinking significantly increase the risk of alcohol poisoning.

Symptoms of alcohol poisoning include mental confusion, difficulty remaining conscious, vomiting, seizures, trouble breathing, slow heart rate, clammy skin, dulled responses (such as a lost gag reflex), and extremely low body temperature.

In December, several tourists at Fiji's Warwick Resort were hospitalized with suspected alcohol poisoning after consuming piña coladas at the resort's pool bar. While the subsequent tests for methanol in the drinks came back negative, one of the affected tourists, Susan, remains convinced that the drinks were tainted.
