“Unveiling the Silent Menace: The Comprehensive Impact of Alcohol on Body, Mind, and Society”
Alcohol, a substance ingrained in various cultures for centuries, may not be receiving the attention it deserves in terms of its impact on the body, mind, and communities. While society may not fully grasp the severity of alcohol’s effects, serious consumption can have detrimental consequences. Common knowledge often highlights liver and kidney damage along with a few heart issues, but the scope extends to include stomach ailments, brain and stomach cancer, significant brain damage, memory loss, and more. While short-term effects may be reversible, the long-term repercussions of alcohol on both the body and mind can lead to a profound cessation of normal functions, posing extensive and enduring challenges.
Impact of alcohol on the liver
The liver, a vital organ responsible for a many essential functions in the human body, becomes a focal point of concern when it comes to the effects of alcohol consumption. Excessive drinking can have severe consequences on the organ, leading to a spectrum of conditions collectively known as alcoholic liver disease (ALD).
The liver plays a crucial role in metabolizing alcohol. When someone drinks alcohol, the liver breaks it down into various byproducts, including acetaldehyde, a toxic substance that can cause damage to liver cells. Over time, persistent alcohol abuse overwhelms the liver’s capacity to process these substances efficiently, leading to a range of liver-related complications.
Chronic and excessive alcohol consumption produces a wide spectrum of hepatic lesions, the most characteristic of which are steatosis, hepatitis, and fibrosis/cirrhosis. Steatosis is the earliest response to heavy drinking and is characterized by the deposition of fat in hepatocytes. Steatosis can progress to steatohepatitis, which is a more severe, inflammatory type of liver injury. This stage of liver disease can lead to the development of fibrosis, during which there is excessive deposition of extracellular matrix proteins. The fibrotic response begins with active pericellular fibrosis, which may progress to cirrhosis, characterized by excessive liver scarring, vascular alterations, and eventual liver failure. Among problem drinkers, about 35 percent develop advanced liver disease because a number of disease modifiers exacerbate, slow, or prevent alcoholic liver disease progression. There are still no FDA-approved pharmacological or nutritional therapies for treating patients with alcoholic liver disease. Cessation of drinking (i.e., abstinence) is an integral part of therapy. Liver transplantation remains the life-saving strategy for patients with end-stage alcoholic liver disease.
In liver diseases linked with alcohol, liver cirrhosis is a major concern. Statistics show that liver cirrhosis is one of the top 10 causes of death worldwide and this in itself indicates the severity of the same. The changing lifestyle and also many people turning to prolonged alcohol intake for many years are contributing to the increased number of liver cirrhosis patients in the modern world. In liver cirrhosis patients, there occurs an increased severity of fibrosis due to the loss of parenchyma and fibrous scar proliferation . Alcoholic liver disease (ALD) is an umbrella term which incorporates a wide range of injuries of the liver, spanning from simple steatosis to cirrhosis, and this also includes alcohol-related fatty liver disease (AFLD) and alcoholic hepatitis.
Impact of alcohol on the nervous system
The central nervous system (CNS) is the major target for adverse effects of alcohol and extensively promotes the development of a significant number of neurological diseases such as stroke, brain tumor, multiple sclerosis (MS), Alzheimer’s disease (AD), and amyotrophic lateral sclerosis (ALS). Excessive alcohol consumption causes severe neuro-immunological changes in the internal organs including irreversible brain injury and it also reacts with the defense mechanism of the blood-brain barrier (BBB) which in turn leads to changes in the configuration of the tight junction of endothelial cells and white matter thickness of the brain. Neuronal injury associated with malnutrition and oxidative stress-related BBB dysfunction may cause neuronal degeneration and demyelination in patients with alcohol use disorder (AUD); however, the underlying mechanism still remains unknown.
In the presentation of the catastrophic or global loss of brain tissue, significant cortical-subcortical volume loss including white matter shrinkage occurs in patients with AUD, which is caused either by nutritional deficiency associated with alcoholic excitotoxicity or oxidative stress which results in alteration of various types of normal brain function. Furthermore, there is interest in the alcohol-induced metabolic disorder, Wernicke-Korsakoff syndrome (WKS), which is associated with thiamine deficiency and may contribute to severe neurological damage in the thalamus and hypothalamus. A combined effect of nutritional deficiency and ethanol toxicity may cause severe long-term effects and worsen the clinical manifestation of neurological impairment. In general, persistent alcohol consumption may lead to gradual deterioration of psychological status with varying degrees of cognitive impairment including severe dementia. Alcohol is the second leading cause of dementia (10%) among the adult population in the US after Alzheimer’s disease (40–60%).
Impact of alcohol on the cardiovascular system
Chronic alcohol intake is undoubtedly a very important risk factor as far as cardiovascular diseases are concerned and several clinical trials do point out this fact. The results of several research studies conducted in various settings clearly indicate that increased intake of alcohol has increased adverse effects on our heart and its vasculature. Alcohol exerts its action on the cardiovascular system both directly and indirectly. Blood pressure, a very vital player in the domain of cardiovascular diseases, is in turn itself affected by increased alcohol consumption. Blood pressure gets increased on regular consumption of alcohol in a manner which is dose-dependent, which in turn increases the risk of hypertension and eventually leads to various cardiovascular complications. How exactly alcohol causes hypertension is still unclear with many pathophysiological theories out there. Atrial fibrillation, one of the most common causes of arrhythmia, is associated with the high-volume chronic intake of alcohol and above 14 g alcohol/day, the relative risk dramatically increases by 10% for each extra standard drink (14 g ethanol) .
Cerebrovascular accidents are increased to a great extent at almost all levels of alcohol intake. Alcohol intake leads to both acute (depresses the cardiac function and also alters the blood flow of the involved region) and chronic cardiovascular manifestations . Alcohol abuse along with other associated factors is one of the leading causes of secondary cardiomyopathy. Cardiac arrhythmias get precipitated by alcohol consumption, be it acute or chronic. Heavy alcohol drinking is shown to impact the cardiovascular system in many ways, one of the most important among them being rebound hypertension. Apart from congenital disorders of the cardiovascular system, it indeed is a very well-evident fact, which could be understood from the history of most of the patients diagnosed with cardiovascular disorders, that they used to consume a lot of alcohol for many years.
Impact of Alcohol on Nutritional Health
Empty Calories and Imbalances: Alcoholic beverages are often laden with empty calories, providing little to no nutritional value. These liquid calories, devoid of essential nutrients, can upset the delicate balance of a well-rounded diet. Excessive alcohol consumption may contribute to imbalances, leading to potential deficiencies in vital vitamins and minerals.
Nutrient Absorption Interference: Alcohol interferes with the body’s ability to absorb key nutrients, including vitamin B12, thiamine, and folic acid. Deficiencies in these essential vitamins can have far-reaching health consequences, from anemia to cognitive impairment and an increased vulnerability to infections. Understanding how alcohol disrupts nutrient absorption underscores the importance of mindful dietary choices.
Displacement of Nutrient-Dense Foods: In the context of a balanced diet, alcohol has the potential to displace nutrient-dense foods. This displacement, coupled with alcohol’s direct negative effects on nutrient absorption and metabolism, emphasizes the need for moderation in alcohol consumption. Striking a balance between enjoying a drink and prioritizing nutrient-rich foods is crucial for optimal nutritional health.
Hormonal Imbalance and Dietary Choices: Alcohol disrupts the body’s hormonal balance, influencing appetite regulation and dietary choices. Individuals who consume alcohol may be more prone to making poor food choices, opting for high-calorie, low-nutrient options. This tendency can contribute to weight gain and further nutritional imbalances, highlighting the importance of mindful eating habits alongside responsible alcohol consumption.
Impact on Bone Health: Excessive alcohol intake may hinder the absorption of minerals like calcium, leading to bone health issues such as osteoporosis. The negative impact on bone density increases the risk of fractures and other skeletal problems. Understanding this connection emphasizes the need for individuals to be aware of the potential consequences of alcohol consumption on long-term bone health.
Impact of alcohol on other systems
Apart from the systemic manifestations which do affect a particular system of the body, there are various disorders in which alcohol indirectly provides its crucial contribution. It is a common finding that one could perceive that alcohol is most of the time in the list of risk factors for various diseases. Alcohol has been found to adversely affect our immune system and the matter of concern as far as this issue is concerned is that immune responses are influenced by even moderate amounts of alcohol intake. Alcohol affects innate immunity and also interferes with almost all the various aspects of the adaptive immune response. Alcohol is a key player in impairing anti-inflammatory cytokines and also promotes proinflammatory immune responses. The gastrointestinal biome is severely manipulated by the use of alcohol over a long period of time, which in turn is found to have a link with the establishment of various complications. Alcohol and its metabolites are found to promote inflammation in the intestines and they do so through varied pathways. Alcohol being a teratogen is documented to cause abnormalities of the brain, limbs, etc. Multiple studies have been conducted across the globe to understand the effect of alcohol on humans
Conclusion
Alcohol seldom leaves any system untouched as far as leaving its impression is concerned, spanning from single tissue involvement to complex organ system manifestations. Almost all the major organs that make up a human’s physiological being are dramatically affected by the overconsumption of alcohol. There is an enormous overall economic cost that is paid for alcohol abuse all over the world.
