Beer Overload: Yeast Infection Culprit?

Drinking too much beer can increase the risk of yeast infections, but it is not a direct cause. Beer contains both yeast and sugar, which can increase the likelihood of developing a yeast infection, especially if consumed in large amounts. Yeast infections are fungal infections typically occurring on the skin or mucous membranes and are caused by the fungus Candida albicans. While drinking beer may not directly result in a yeast infection, it can heighten the chances of getting one.

Alcohol consumption and its effect on the immune system

Alcohol consumption can have detrimental effects on the immune system, which in turn can increase the risk of developing a yeast infection. The immune system is our body's defence mechanism against infections, diseases, and toxins. It comprises two parts: the innate immune system, which provides general immunity by responding to viruses, bacteria, and other microorganisms, and the adaptive immune system, which deals with immune memory, recognising previous infections and preventing them from reoccurring.

Excessive alcohol consumption can negatively impact both parts of the immune system. Even drinking 5-6 drinks in a single session can suppress the immune system for up to 24 hours. Over time, alcohol consumption can cause longer-term issues, as the immune system takes longer to recognise and respond to infections, leading to more intense and prolonged illnesses.

Alcohol's impact on the immune system can be observed in various parts of the body:

Lungs

The lungs are particularly vulnerable to the effects of alcohol. Excessive drinking can impact the immune cells that protect the lungs and the cells within the airways, reducing their ability to remove mucus. This can damage lung tissue and weaken lung function over time. This weakening often goes unnoticed until a severe infection occurs. Heavy drinking significantly increases the risk of developing serious conditions like pneumonia from common respiratory tract infections.

Gut

A healthy gastrointestinal (GI) tract requires a diverse range of 'good' bacteria for optimal immune function. Alcohol can impact the number and variety of these bacteria, disrupting the gut microbiota and worsening the immune system. The cells lining the GI tract regulate what is absorbed into the body, and alcohol affects these cells, contributing to the development of alcohol liver disease. Alcohol also damages epithelial cells, T cells, and neutrophils in the GI system, disrupting gut barrier function and allowing microbes to leak into the circulation. This disruption can have systemic effects, such as triggering inflammation in the liver, which can lead to alcoholic liver disease (ALD) and potentially liver cirrhosis and liver cancer.

Blood Sugar Levels

Consuming alcohol can lead to fluctuations in blood sugar levels. Since yeast, such as Candida, thrives on sugar, elevated blood sugar can create an environment conducive to yeast growth.

Candida Overgrowth

Candida is a type of yeast fungus that normally lives in small amounts in the human body, particularly in the mouth, intestines, and skin. However, when Candida grows uncontrollably, it causes an infection called Candidiasis. Heavy drinking is a leading cause of Candida overgrowth as it can alter the microbes in the esophagus and weaken the immune system, which is crucial for keeping Candida cells in check. Studies show that just 2 hours after drinking alcohol, white blood cell levels drop significantly, leaving the body vulnerable to Candida. Additionally, drinking damages the liver, which is the body's primary defence against Candidiasis symptoms.

Adrenal Glands

The adrenal glands are small organs located above the kidneys that produce hormones to regulate bodily processes. When drinking excessively, blood glucose levels drop, causing the adrenal glands to produce the stress hormone cortisol. While cortisol raises blood sugar, it also tires out the adrenal glands, which are essential for maintaining the immune system and preventing Candida overgrowth.

The amount of live yeast in beer

While drinking beer may not directly cause a yeast infection, it can increase the chances of getting one. Beer is made by brewing and fermenting starches, mainly derived from cereal grains. Yeast is an essential ingredient in making beer. It begins the process of converting sugars into alcohol and carbon dioxide.

Yeast is a living organism—a unicellular fungus, to be precise. The majority of beers use a yeast strain called Saccharomyces, which translates from Latin to "sugar fungus". Within the Saccharomyces genus, there are two specific species of yeast that are most commonly used: lager yeast and ale yeast.

Lager yeast, or Saccharomyces pastorianus, is a bottom-fermenting yeast that sits on the bottom of the tank during fermentation. It was originally discovered and cultivated by Bavarian brewers over 200 years ago. Lager yeast prefers much lower temperatures than ale yeast, typically between 48°F and 58°F. It is the most commonly used yeast in terms of the total volume of beer produced globally.

Ale yeast, or Saccharomyces cerevisiae, is a top-fermenting yeast that rises to the top of the beer during fermentation. It ferments best at higher temperatures, typically between 50°F and 70°F, with some saison yeasts reaching temperatures in the nineties during peak fermentation. Ale yeast is responsible for a wide range of beer styles, including IPAs, stouts, and ambers.

While moderate alcohol consumption may not directly cause a yeast infection, heavy or frequent drinking could increase the risk, especially if your gut health is already compromised. Alcohol can disrupt the balance of gut microbiota, weaken the immune system, and alter the microbe of the oesophagus, all of which can contribute to the growth of yeast and the development of a yeast infection.

Alcohol's impact on the liver

Alcohol is indeed hard on the liver, and it is considered one of the main causes of liver complications. Alcohol consumption can lead to liver disease, which is a broad term encompassing various conditions that impair normal liver function. Liver disease affects approximately 4.5 million adults in the United States.

The liver is responsible for removing toxins like alcohol from the bloodstream, regulating blood clotting, and producing bile, among other functions. When the liver is damaged, its functioning is reduced. Heavy alcohol consumption can lead to a condition called steatosis, where excess alcohol is turned into fat and stored in the liver. This fat interferes with the liver's function and causes cell death.

The early stages of liver disease often present no symptoms, making it challenging to detect. However, some people may experience fatigue, abdominal pain, increased bruising, or itching. As the disease advances, signs and symptoms become more apparent and include jaundice (yellowing of the skin or eyes), pain and distension of the abdomen, swelling of the lower legs, and confusion or forgetfulness.

Alcohol consumption can also disrupt the balance of gut microbiota, including beneficial bacteria that help keep yeast growth in check. This disruption can lead to an overgrowth of yeast, such as Candida, which can cause yeast infections. Additionally, alcohol weakens the immune system, making it less effective at fighting off infections, including yeast infections.

To maintain a healthy liver and reduce the risk of liver disease and yeast infections, it is essential to drink in moderation or abstain from alcohol altogether. Moderate alcohol consumption is generally defined as no more than one drink per day for women and no more than two drinks per day for men.

Alcohol's effect on adrenal glands

Drinking too much beer can increase the risk of developing a yeast infection. Beer contains both yeast and sugar, and excessive drinking can be a recipe for yeast infections as yeast can enter the bloodstream and sugar acts as a food source for yeast.

Alcohol's Effect on the Adrenal Glands

The adrenal glands are small triangular glands that sit on top of each kidney. They produce hormones, such as adrenaline and cortisol, which help the body respond to stress. Adrenal dysfunction, or adrenal fatigue, can lead to hormonal imbalances and impact overall health.

Alcohol consumption can have a significant impact on the functioning of the adrenal glands, particularly by affecting cortisol levels. Here are some ways in which alcohol affects the adrenal glands:

• Increased Cortisol Levels: Alcoholism and high alcohol consumption have been linked to increased cortisol levels in the body over time. Cortisol is a stress hormone that can temporarily shut down other bodily functions, and chronic release of cortisol can lead to negative health consequences.
• Disruption of the Hypothalamic-Pituitary-Adrenal (HPA) Axis: The HPA axis is a major component of the neuroendocrine system that controls the body's response to stress. Alcohol consumption can disrupt the HPA axis, leading to hormonal imbalances and various disorders, including stress abnormalities, reproductive issues, thyroid problems, immune dysfunction, and psychological disorders.
• Blood Sugar and Weight Gain: Alcohol can impact blood sugar levels, causing them to drop dangerously low. This can lead to symptoms such as lightheadedness and fatigue, which are also associated with adrenal fatigue. Additionally, alcohol can increase cravings, lower inhibitions around food, and contribute to weight gain.
• Sleep Disturbances: While alcohol may help individuals fall asleep faster, it interferes with the vital REM sleep stage, leading to mental fog and memory problems. It also acts as a diuretic, causing more frequent urination and disrupting sleep.
• Impact on Heart and Liver: Regular heavy drinking or binge drinking can lead to heart problems such as high blood pressure and irregular heartbeat. Additionally, alcohol consumption puts a strain on the liver, which has to work overtime to metabolize alcohol, disrupting its other functions.

To support adrenal health, it is important to limit alcohol consumption and explore alternative stress relief techniques such as gentle exercise, meditation, and processing emotional trauma.

Alcohol's effect on blood glucose levels

Alcoholic drinks contain varying amounts of sugar and calories, and excessive alcohol consumption can lead to weight gain and long-term health problems. For instance, drinking alcohol can alter blood sugar levels, increasing the risk of developing alcohol-related diabetes and posing a significant danger to those already living with the condition.

When you drink alcohol, your liver chooses to metabolize it instead of maintaining your blood glucose levels, which can lead to hypoglycaemia. This is especially true when you drink on an empty stomach. The symptoms of hypoglycaemia, such as slurred speech, drowsiness, confusion, and difficulty walking, can be difficult to distinguish from the signs of drunkenness. Furthermore, hypoglycaemia can occur hours after your last drink, especially if you've been exercising.

In addition, alcohol can disrupt the balance of gut microbiota, allowing yeast to overgrow. Yeast infections, such as those caused by the fungus Candida albicans, thrive on sugar. Since beer and wine contain both yeast and sugar, excessive drinking can increase the risk of developing a yeast infection.

While moderate drinking may not directly cause a yeast infection, heavy or frequent drinking could increase the risk or exacerbate existing conditions. Therefore, if you are prone to yeast infections, it is advisable to monitor your alcohol intake.
