The Effects of Alcohol Use & Addiction

As the most regularly used potentially addictive substance in America, the National Council on Alcoholism and Drug Dependence (NCADD) reports that alcohol is often part of daily life.

When you drink, alcohol depresses the central nervous system, slowing everything down and impairing cognitive functions. Alcohol can cause you to act in ways that are out of character, as it lowers your inhibitions and increases sociability.

Excessive and chronic alcohol use can lead to addiction as well as a host of mental and medical issues.

Alcohol is broken down by the liver. In general, the liver can metabolize about one serving of alcohol every hour.

If you go over what your liver can break down, your BAC will go up and so will the impact on your brain and body. Low to moderate levels of alcohol use can make you feel relaxed, impair motor coordination and reflexes, and cause blurred vision, slurred speech, lowered blood pressure and heart rate, nausea, memory loss, and drowsiness.

Negative effects of moderate drinking could include for example, taking bigger risks than usual that come with undesirable consequences, physical, financial, legal, or such.

Patterns of excessive drinking can be especially harmful to your health. The Centers for Disease Control and Prevention (CDC) reports that binge drinking is the most common.

Heavy alcohol use is when you engage in binge drinking at least five times in a month, the CDC further explains.

Binge drinking amplifies the impact of moderate doses of alcohol. It can lead to even more physical and mental impairment, causing motor skills to be impacted, and balance and coordination to be even more off. Your reaction time is delayed, and it is not safe to drive at this point.

The more you drink, the more impaired you will get. You can become confused and vomit. You may have less of a response to pain, limited muscle control, and difficulties seeing, thinking, and hearing well.

When you drink excessively and regularly, your brain starts to develop a tolerance. This can mean that you will have to consume more to feel a buzz from drinking.

Most people who drink alcohol have experienced a hangover the next day. Symptoms include headache, nausea, dizziness, vomiting, dehydration, lethargy, sleep problems, irritability, sweating, loss of appetite, mood swings, fatigue, depression, anxiety, tremors, and rapid heart rate.

Long-term and repeated alcohol use can really take a toll on your brain and body. Many of your internal organs and systems will suffer. The liver, brain, pancreas, and heart can all be damaged as result of alcoholism.

Excessive and repeated patterns of alcohol use can increase your risk for many forms of cancer, including cancer of the bowel, mouth and neck, liver, and breast. It can also lead to liver and heart disease, high blood pressure, pancreatitis, stroke, depression, dementia, and sexual dysfunction and infertility issues, the National Health Service (NHS) warns.

Alcohol can influence many of the body’s systems and organs.

Alcohol is a depressant, which means it slows down the functions of your central nervous system. The more you drink, the greater the impact.

The central nervous system is involved in many life-sustaining functions, such as heart rate, blood pressure, and body temperature. When you drink, all of these functions are slowed. When alcohol wears off, they can then be heightened. The consistent push-and-pull impact of regular alcohol abuse can lead to irregularities in heart rate and blood pressure that can raise the risk for stroke and cardiovascular issues.

The journal Current Neurovascular Research publishes that alcohol suppresses the activity in the excitatory nerve pathways, interacts with receptors, and disrupts communication between nerve cells in the brain. This can cause neuronal injury, neurodegeneration, and neurocognitive defects.

Korsakoff psychosis is a form of permanent brain damage, NLM explains. It can impact memory formation, cause hallucinations, and interfere with your ability to function and live on your own.

Alcohol use, and alcohol use disorder especially, can negatively impact your lungs and respiratory system. Over time, drinking regularly interferes with your body’s immune system, which can make it harder to fight off certain illnesses and diseases.

Your circulatory system involves your blood vessels, veins, capillaries, blood, arteries, and heart. Drinking too much too often can have a negative impact on your circulatory and cardiovascular system.

Alcohol can slow down your bodily functions, how fast your heart pumps, and therefore how blood is moved throughout the body.

Alcohol can have numerous effects on the digestive system, including an impact on appetite.

Drinking can cause you to make poor food choices that can lead to issues with weight and overall health. Conversely, alcohol withdrawal can cause stomach discomfort and vomiting, leading to a lack of appetite and potential malnutrition.

Alcohol has no nutritional value and can be toxic to the digestive system. Alcohol use can increase the risk for mouth, throat, bowel, and liver cancers. It can cause acid buildup and acid reflux.

Alcohol can have significant impact on the liver. As the American Liver Foundation (ALF) publishes, regular and chronic alcohol consumption can cause alcohol-related liver disease. The liver is the organ in your body designated for helping you metabolize things and process out toxins.

Liver disease from alcohol use progresses in three stages, starting out with fatty liver disease, or steatosis. This happens as the liver metabolizes alcohol, and fat begins to build up. It can progress to alcoholic hepatitis, which can have life-threatening complications. Both of these forms of alcohol-related liver disease can be overturned if you stop drinking and get medical attention.

The third progression of the disease, alcohol-related cirrhosis, involves irreversible scar tissue formation. This can be serious and fatal.

Alcohol impacts nearly every system in the body, including your bone health. Chronic and excessive alcohol use can be a factor in decreased bone density, which can raise your risk for osteoporosis, the National Institutes of Health (NIH) publishes. Osteoporosis elevates the odds for bone fractures.

Your endocrine system helps to regulate your internal systems, allowing your organs to communicate with each other to make sure everything is working as it should. Your pituitary gland and hypothalamus act as a kind of “control center” for both your endocrine and nervous system. Alcohol can be detrimental to both of these parts of your brain.

Your urinary, or renal, system involves your kidneys, bladder, sphincter, ureters, and urethra. It works to remove waste from your body.

Drinking alcohol can irritate the urinary system and make you feel like you need to urinate more often than normal. Alcohol can also lead to dehydration. Since your kidneys work to filter your blood, this kind of “drying out” can impact the ability of your kidneys to keep the necessary amount of water in your body.

Alcohol abuse can lead to a worsening of kidney disease and problems with your liver, which impact the kidneys. When the liver can’t work the way it needs to, your kidneys take on the extra work. The National Kidney Foundation publishes that the majority of Americans struggling with both kidney dysfunction and liver disease battle alcohol dependence as well.

Alcohol can impact both female and male reproductive systems, affecting production of the sex hormones testosterone in men and estrogen in women. Alcohol use can disrupt a women’s menstrual cycle, which then can interfere with estrogen production, ovulation and therefore fertility and reproduction.

The lymphatic system is part of your immune system. Alcohol can inflame lymph nodes and decrease the ability of your immune system to function as well as it is intended to.

When you drink, your blood vessels dilate, and lymph fluid is increased throughout the body. Your kidneys also excrete more fluid as alcohol is a diuretic. Excessive alcohol consumption can cause swelling in your lymph nodes, which can be painful.

Alcohol use and excessive lymph node function can particularly be an issue if you suffer from lymphedema or lymphoma already.

Your integumentary system involves your sweat or exocrine glands, nails, hair, and skin. Like virtually all other parts of your body, alcohol can impact it too.
