Beer And Your Gut: The Surprising Truth

Drinking too much beer can have negative consequences for your health, and your gut is no exception. Alcohol can irritate the gut and cause acid reflux, also known as heartburn, as well as more serious conditions such as gastritis and peptic ulcers. Alcoholic gastritis, caused by drinking too much, too often, can irritate and erode the stomach lining, leading to symptoms such as stomach ache, abdominal pain, hiccups, indigestion, loss of appetite, bloating, and nausea. The effects of drinking beer on the gut can range from mild discomfort to more severe, long-term health issues.

Alcoholic gastritis

The symptoms of alcoholic gastritis can be non-specific and may be mistaken for common gastrointestinal problems like indigestion or acid reflux. Some common symptoms include a gnawing or burning ache in the belly, stomach pain in the upper abdomen, vomiting blood or coffee ground vomit, and blood in the stool or black, tarry stools. However, it's important to note that not everyone experiences symptoms of alcoholic gastritis.

If left untreated, alcoholic gastritis can lead to serious complications such as gastrointestinal tract bleeding, which can be a medical emergency. It can also cause permanent damage to the stomach and digestive system if alcohol consumption continues. Other gastrointestinal risks associated with excessive alcohol consumption include gastroesophageal reflux disease (acid reflux), upper gastrointestinal bleeding, polyps and tumors in the stomach, pancreatitis, and an increased risk of various cancers.

The treatment for alcoholic gastritis involves quitting alcohol and using medications to control gastric mucosal inflammation. Medications prescribed for alcoholic gastritis treatment may include antibiotics, antacids, H2 blockers, and proton pump inhibitors to heal and protect the stomach lining. Lifestyle changes, such as eating smaller meals, avoiding spicy or acidic foods, and quitting smoking, are also recommended during treatment.

To lower the risk of alcoholic gastritis and other alcohol-related health issues, it is essential to follow low-risk drinking guidelines, such as not drinking more than 14 units of alcohol per week, avoiding binge drinking, and having several drink-free days.

Acid reflux

Drinking too much beer can lead to acid reflux, which is when acid and other contents from your stomach back up and irritate the oesophagus, causing a burning sensation in the chest, often referred to as heartburn. This is because alcohol can increase the production of gastric acid, which is the primary cause of heartburn and regurgitation. The more alcohol consumed, the higher the risk of acid reflux.

Beer and wine have been found to trigger reflux compared to drinking water. However, spirits with a high ethanol content, such as gin, whiskey, and cognac, may be better for those prone to acid reflux. This is because high-proof spirits are less likely to stimulate stomach acid secretion than drinks with lower ethanol content. Spirits with a lower pH level, such as tequila and non-grain vodka, may also help reduce the risk of acid reflux.

To reduce the risk of acid reflux, it is recommended to limit alcohol consumption to one drink per day and avoid drinking 2-3 hours before bed, as lying flat after drinking can increase the risk of acid reflux at night.

Leaky gut

Drinking too much alcohol can lead to a "leaky gut", which is when gaps in the intestinal wall allow bacteria and other toxins to enter the bloodstream. This is caused by an imbalance in the gut's bacterial composition, with an increase in bacteria that cause inflammation and a decrease in bacteria that aid digestion.

The intestinal barrier is made up of a layer of water, mucus gel, and epithelial and connective tissue. Alcohol disrupts the epithelial cells and the spaces between them, which consist of tight junctions, the cytoskeleton, and several associated proteins. This disruption leads to a leaky gut, which can have various negative health consequences.

Alcohol also causes cell death and direct cellular damage through the formation of DNA adducts and the release of reactive oxygen species (ROS) during alcohol metabolism. These factors further contribute to the development of a leaky gut.

Additionally, alcohol affects the mucosal immunity of the intestine by decreasing the innate immune response and triggering an inflammatory response, leading to the release of inflammatory immune cells. This disruption in the mucosal immunity can also contribute to a leaky gut.

Overall, excessive alcohol consumption can lead to a leaky gut by disrupting the intestinal barrier and affecting the balance of bacteria and immunity in the gut. This can have negative health effects throughout the body.

Diarrhea

Drinking too much beer can have adverse effects on your gut, and one of the most common issues is diarrhea. Alcohol can irritate the lining of your intestines, causing them to leak fluid into your gut and increasing the frequency and intensity of muscle contractions. These contractions trigger your urge to go to the toilet as they move waste through your system.

The irritation caused by alcohol can also make it harder for your intestines to absorb fluid, leaving your stool in a pre-dehydrated state. This irritation can also cause inflammation in the gastrointestinal tract, further contributing to diarrhea.

Additionally, alcohol affects the balance of bacteria in your gut. It can kill off good bacteria, allowing bad bacteria to grow rapidly, which can cause intestinal malfunction and further impair your intestines' ability to absorb water.

Beer, in particular, may be more likely to cause diarrhea due to its higher carbohydrate content compared to other alcoholic beverages. If your body struggles to break down these extra carbs while processing alcohol, it can lead to diarrhea.

To reduce the likelihood of diarrhea after drinking beer, it is recommended to be mindful of your drinking habits, drink slowly, and consume water or non-alcoholic drinks between alcoholic beverages. Eating before drinking can also help slow the absorption of alcohol and reduce the risk of diarrhea.

Vitamin and mineral deficiency

Drinking too much beer can hurt your gut. Alcoholic gastritis, for example, is caused by drinking too much, too often. The alcohol irritates and erodes the stomach lining, triggering gastritis symptoms such as stomach ache, abdominal pain, hiccups, indigestion, loss of appetite, bloating, and nausea.

Alcohol interferes with the natural breakdown of nutrients in several ways, which can lead to vitamin and mineral deficiencies. Firstly, it decreases the secretion of digestive enzymes from the pancreas. Secondly, it impairs nutrient absorption by damaging the cells lining the stomach and intestines. Thirdly, it disables the transport of some nutrients into the blood. Finally, it prevents the full utilization of nutrients that are absorbed by altering their transport, storage, and excretion.

Heavy drinkers are often deficient in one or more vitamins, commonly folate, vitamin B6, thiamine, vitamin A, vitamin C, vitamin D, vitamin E, vitamin K, and B vitamins. These deficiencies can cause a range of health issues, including night blindness, softening of the bones, slow healing of wounds, decreased ability of the blood to clot, severe neurological damage, and Wernicke-Korsokoff syndrome (a combination of brain damage and psychosis).

Alcohol also depletes essential minerals such as iron, potassium, magnesium, and zinc, which are necessary for healthy growth and body maintenance. Mineral deficiencies may be caused by other alcohol-related conditions, such as decreased calcium absorption due to fat malabsorption, magnesium loss due to excretion, vomiting, and diarrhea, and iron deficiency due to gastrointestinal bleeding.

Restoring nutrition is, therefore, a critical aspect of treating alcohol use disorders.
