Beer Drinking: Friend Or Foe In Acne Battle?

Alcohol is known to have adverse effects on the body and can also negatively impact skin health. While drinking beer doesn't directly cause acne, it can create a hormonal imbalance that might lead to a breakout. Beer, like other alcoholic drinks, can dehydrate the body, which can cause the sebaceous glands in the skin to produce excess oil and lead to acne breakouts. Alcohol also affects the immune system, liver function, inflammation, and hormones, which can all contribute to acne. Additionally, the presence of congeners in beer, such as furfural, can further enhance inflammation and dehydration.

Alcohol and dehydration

Alcohol is a diuretic, which means it increases urine production, flushing out excess water and salt from the body. This can lead to dehydration, which may cause a range of problems, including acne breakouts. Dehydration can also make the skin look sunken or saggy.

Drinking alcohol can dehydrate the body shortly after consumption. This is why it is generally recommended to have a glass of water between alcoholic drinks or to drink water before bed if you forget.

Dehydration caused by alcohol consumption can be counteracted by drinking water regularly, carrying water in a bottle, drinking water on a schedule, or using an app to track fluid consumption. It is also important to drink water while consuming alcohol. Other hydrating beverages can also help, but sugary and caffeinated drinks should be avoided as they can promote dehydration. Eating hydrating foods, such as those with high water content, can also help prevent dehydration.

The risk of dehydration from alcohol consumption is greater for older adults and people with chronic conditions. Additionally, drinking alcohol on an empty stomach can contribute to dehydration as the alcohol goes straight into the bloodstream instead of being absorbed more slowly through the stomach and small intestine.

To prevent dehydration, it is important to consume alcohol in moderation. The Centers for Disease Control and Prevention (CDC) advise that males drink a maximum of two drinks per day and that females have no more than one drink per day. It is also important to drink alcohol slowly, as it takes the liver about one hour to process each serving of alcohol.

Alcohol and inflammation

Alcohol can cause inflammation throughout the body. There are two main types of inflammation that alcohol can cause: acute and chronic. Acute inflammation is when the body has an immediate inflammatory reaction to consuming alcohol, which can be observed through 'hangover' symptoms such as headaches, nausea or vomiting. These symptoms usually don't last long and go away within a couple of days without treatment. Chronic inflammation, on the other hand, gets worse over time.

Recent research suggests that alcohol causes inflammation in the intestines and impairs the body's ability to regulate it. This, in turn, worsens alcohol-related organ damage. Excessive drinking can have serious implications for long-term health.

Inflammation is a natural part of the human immune system. When you get a cut or have an infection, acute inflammation occurs as your body's way of eliminating something harmful so that you can begin to heal. However, chronic inflammation, which lasts from a few months to a few years, is a major contributor to various chronic diseases, such as cardiovascular diseases, rheumatoid arthritis, chronic obstructive pulmonary disease (COPD), Alzheimer's disease, and chronic kidney disease (CKD).

When the body breaks down alcohol, it leaves behind inflammatory compounds that can cause damage to the gut, liver, and other organs. This damage triggers an inflammatory response in the body. Alcohol also disrupts your gut health, which plays a role in immune health and chronic inflammation. Drinking alcohol, especially in excess, can directly harm the gastrointestinal system and lead to gastrointestinal symptoms like diarrhoea or increased gastric acid secretion, which can indirectly harm your gut microbiome.

Alcohol consumption increases intestinal permeability, allowing inflammation-inducing lipopolysaccharides to reach the liver and brain. It also reduces the production of anti-inflammatory bacteria in the gut and increases the production of inflammatory bacteria. Additionally, alcohol can cause an imbalance in gut bacteria, negatively impacting the immune system.

To reduce the inflammatory effects of alcohol, it is recommended to limit alcohol intake, stay hydrated, and eat anti-inflammatory foods such as tomatoes, olive oil, nuts, fatty fish, leafy green vegetables, and fruits.

Alcohol and hormones

Alcohol can have a wide range of effects on the body's hormones, which in turn can have a wide range of effects on the body.

Adrenal glands

Alcohol suppresses the function of the adrenal glands, which produce steroid hormones that help regulate metabolism, blood pressure, immune function, and more. Regular alcohol consumption can lead to adrenal fatigue, which can cause a range of issues, including decreased ability to fight off disease, increased food cravings, weight gain, and sexual dysfunction.

Vitamin C levels

The body needs vitamin C to break down alcohol, and heavy drinking can lead to a vitamin C deficiency unless it is replenished through diet or supplements.

Blood sugar levels

Alcohol interferes with the body's production of insulin, the hormone that controls blood glucose levels. This can lead to an increased risk of type 2 diabetes and hyperglycaemia in those with pre-existing diabetes.

Cortisol levels

While alcohol initially lowers cortisol levels, which can temporarily reduce stress, chronic drinking can increase cortisol levels, especially during withdrawal. Increased cortisol can cause stress, anxiety, digestive issues, mood swings, high blood pressure, reduced immunity, and poor sleep.

Reproductive functions

Alcohol can impair the functioning of the testes and ovaries, leading to hormonal deficiencies, sexual dysfunction, and infertility. It can also alter normal sperm structure, reduce testosterone levels, and cause male breast enlargement. In women, alcohol consumption can lead to irregular menstrual cycles, menstrual cycles without ovulation, and a risk of spontaneous abortions.

Calcium metabolism and bone structure

Hormones play a crucial role in maintaining calcium levels, which are necessary for strong bones and teeth. Alcohol can interfere with these hormones, leading to calcium deficiency and an increased risk of osteoporosis.

Alcohol and the liver

The liver is a robust organ that can usually process small amounts of alcohol. However, heavy drinking can cause liver damage. The liver breaks down and filters out harmful substances in the blood, and it manufactures proteins, enzymes, and hormones that the body uses to ward off infections. It also converts vitamins, nutrients, and medicines into substances that our bodies can use. The liver is also responsible for cleaning our blood, producing bile for digestion, and storing glycogen for energy.

The liver processes over 90% of consumed alcohol. The rest exits the body via urine, sweat, and breathing. It takes the body approximately one hour to process one alcoholic beverage. This time frame increases with each drink. The higher the blood alcohol content, the longer it takes to process the alcohol. The liver can only process a certain amount of alcohol at a time. When someone has too much to drink, the alcohol left unprocessed by the liver circulates through the bloodstream. The alcohol in the blood starts to affect the heart and brain, which is how people become intoxicated.

Chronic alcohol abuse causes the destruction of liver cells, which results in scarring of the liver (cirrhosis), alcoholic hepatitis, and cellular mutation that may lead to liver cancer. These conditions usually progress from fatty liver to alcoholic hepatitis to cirrhosis, although heavy drinkers may develop alcoholic cirrhosis without first developing hepatitis.

Heavy drinkers have an increased risk of jaundice, cirrhosis, liver failure, liver cancer, and many other conditions. Consuming two to three alcoholic drinks daily can harm one's liver. Binge drinking (consuming four or five drinks in a row) can also result in liver damage.

Mixing alcohol with other medications can be dangerous for your liver. For example, certain medications, such as acetaminophen, can lead to severe liver damage when combined with alcohol. Other medications that are dangerous to combine with alcohol include antibiotics, antidepressants, sedatives, and painkillers.

The most effective way to reverse or prevent alcohol-related liver problems is to cut back on alcohol consumption or stop drinking altogether.

Alcohol and the immune system

Alcohol has a negative impact on the immune system, which is designed to fight off infections, diseases, and toxins. The immune system is made up of two parts: the innate immune system and the adaptive immune system.

Drinking alcohol can suppress the immune system for up to 24 hours, even if you're not a regular heavy drinker. Consuming 5-6 drinks in one sitting can have this effect. Over time, drinking can lead to longer-term problems as the immune system takes longer to recognize and respond to infections. This can result in more intense illnesses, longer-lasting symptoms, and the immune system having to work harder to fight off infections.

The gastrointestinal (GI) tract is typically the first point of contact for alcohol as it passes through the body. One of the most significant immediate effects of alcohol is that it affects the structure and integrity of the GI tract. Alcohol alters the number and relative abundance of microbes in the gut microbiome, which aid in normal gut function and affect the maturation and function of the immune system. Alcohol also damages epithelial cells, T cells, and neutrophils in the GI system, disrupting gut barrier function and facilitating the leakage of microbes into the circulation.

Alcohol also impacts the lungs, which are particularly vulnerable to the effects of alcohol. Excessive drinking can impact the immune cells that protect the lungs and reduce their ability to remove mucus. This can damage lung tissue and lead to a weakening of lung function over time. Heavy drinking can result in a 3-7 times higher vulnerability to serious conditions, like pneumonia, developing from common respiratory tract infections.

Alcohol's effects on the immune system are complex and multifaceted. It disrupts immune pathways in ways that can impair the body's ability to defend against infection, contribute to organ damage associated with alcohol consumption, and impede recovery from tissue injury.
