The Far-reaching, Multifaceted Effects of Excessive Alcohol Consumption on Human Health

It is widely understood that excessive alcohol consumption leads to intoxication. This fact is not limited to alcoholics alone. Prolonged and excessive alcohol intake can potentially cause damage to the liver. However, it's important to note that alcohol doesn't only affect the liver; it impacts various organs throughout the body, including the lungs, heart, spleen, kidney, esophagus, pancreas, stomach, and even skeletal muscles.

When we consume alcoholic beverages like Heineken, Moet, or Chamdor, we are essentially ingesting ethanol at different concentrations mixed with other minor ingredients. It's essential to understand that ethanol itself does not hold any inherent significant importance for the body. If ethanol were necessary for your well-being, your doctor would prescribe it in appropriate doses. From the moment alcohol enters the body until it is eliminated, it poses harm and triggers various battles within the body.

No One's Left Out

Our liver plays a vital role in detoxifying ethanol. It converts it using alcohol dehydrogenase (ADH) into a toxic compound called acetaldehyde, which is primarily responsible for the damage caused by alcohol consumption.

Ethanol, being a nonpolar solvent, dissolves lipids. When it comes into contact with lipids in the body, especially in cell membranes, it corrodes them due to its nature. This can lead to inflammation in cells as the lipids on the cell membrane are affected.

In the brain, ethanol binds to GABA receptors in the limbic system, enhancing the activity of GABA neurotransmitters. This depresses the nervous system and impairs the absorption of thiamine by brain cells. Over time, the lack of thiamine absorption can lead to the death of brain cells. However, it's important to note that this doesn't happen immediately, as individuals with dead brain cells due to alcohol consumption would require immediate medical attention. Prolonged alcohol abuse can lead to a condition known as Wernicke-Korsakoff syndrome. Additionally, alcohol affects the release of vasopressin in the pituitary gland, but we will explore this further shortly.

Consuming alcohol with a high concentration (above 15% by volume) can lead to indigestion or delayed digestion of food. It can also denature digestive enzymes, leading to a bacterial infestation of the food, which causes stomach discomfort due to the gas released by the bacteria.

Once alcohol reaches the intestines, it gets absorbed into the bloodstream. From there, it affects various organs throughout the body. Have you ever wondered why people smell of alcohol after consuming it? This is because ethanol reaches the lungs and, being of lesser molecular weight compared to carbon dioxide, is released along with CO2. While you may not notice immediate damage, prolonged alcohol consumption can lead to alcoholic lung, which increases the risk of pneumonia, tuberculosis, influenza, and other respiratory conditions.

Alcohol also impacts the heart by increasing heart rate, causing tachycardia. While an increased heart rate may be normal during vigorous activities, it becomes problematic when at rest, as it raises blood pressure.

Some argue that alcohol has no direct contribution to kidney function. However, the intake of alcohol blocks the release of vasopressin in the pituitary gland, which is responsible for the production of antidiuretic hormone. This hormone plays a crucial role in the absorption of water from the kidney into the body. When the release of vasopressin is blocked, it leads to excess urination.

The liver plays a crucial role in detoxifying ethanol in the body, converting it into acetic acid, which is then further metabolized into carbon dioxide and water. However, during the conversion process, some intermediate compounds like acetaldehyde may not fully convert to acetic acid, which can be harmful to liver cells. This leads to liver inflammation and damage, and prolonged heavy alcohol consumption can result in fibrosis, progressing to cirrhosis as the fibrotic liver tissue impairs its detoxification capabilities. Cirrhosis can lead to fluid retention, causing edema. In chronic cases, liver failure can occur.

The pancreas, involved in breaking down alcohol, can also suffer from the effects of excessive alcohol consumption. It can lead to alcoholic pancreatitis, which increases the risk of pancreatic cancer.

Excessive alcohol consumption can also have detrimental effects on bone health. While moderate alcohol intake may not be a cause for concern, excessive alcohol consumption increases the risk of low bone density, ultimately leading to osteoporosis.
