What Are the Effects of Alcohol?

Every person is different; therefore, the effects of alcohol vary from person to person. While some people may be able to limit their drinking, others have a difficult time controlling their alcohol consumption.

In order to fully understand the consequences of drinking, you should first know what constitutes as a drink. One drink is recognized as:

  • 12 fluid ounces of beer – approximately five percent alcohol
  • Eight to nine fluid ounces of malt liquor – about seven percent alcohol
  • Five fluid ounces of wine – roughly 12 percent alcohol
  • One and one-half ounces of 80-proof distilled spirits (vodka, rum, gin, tequila, whisky, etc.) – an estimated 40 percent alcohol

The effects of alcohol can be influenced by a number of risk factors such as the amount consumed, individual’s medical history, tolerance to alcohol, as well as other drugs – legal or illegal – mixed with alcohol.

If you or a loved one is experiencing the effects of alcohol, it’s time to get help. Our treatment professionals can put you in touch with top-rated alcohol rehab facilities that will assist you in getting your life back on track.

Understanding Blood Alcohol Content (BAC)

A person’s blood alcohol content (BAC) determines the effect of alcohol on the central nervous system. Those who have built up a tolerance to alcohol can drink more than those with a lower tolerance level.

Depending on your BAC, you can experience an array of side effects that range from minor complications to more severe ones. For example, lower BAC percentages tend to come with temporary side effects that subside within a few hours. However, as BAC percentages increase, the symptoms become much more serious and can be life-threatening.

Here’s a breakdown of different BAC percentages along with their symptoms:

BAC: 0.033-0.12 Percent

  • Improvement in mood
  • Higher self-confidence
  • Less anxiety
  • Flushing of the face
  • Shorter attention span
  • Lack of fine motor coordination
  • Impairment of judgment

BAC: 0.09-0.25 Percent

  • Sedation
  • Loss of memory and lack of comprehension
  • Delayed motor reactions
  • Balance problems and ataxia
  • Blurred vision and sensation impairment

BAC 0.25-0.40 Percent

  • In and out of consciousness or complete unconsciousness
  • Amnesia during the events while intoxicated
  • Staggering gait
  • Vomiting with aspiration
  • Respiratory depression
  • Incontinence of urine
  • Slowed heart rate

BAC 0.35-0.80 Percent

  • Comatose
  • Lack of pupillary response to light
  • Life-threatening respiratory depression
  • Severe decrease in heart rate
  • Death

How Alcohol Abuse Affects the Body

Alcohol abuse can affect your body both inside and out. Even though you’re unable to see the damage drinking causes to your internal organs, it’s important not to ignore the warning signs of alcoholism. Sometimes the harmful effects aren’t discovered until much later in life, making it difficult to reverse many health complications.

While every organ in your body can feel the effects from drinking, some are more at risk for extensive damage. The best way to prevent health issues now and in the future is to quit drinking with the help of a professional treatment program.


Alcohol’s effects on the brain can be felt quickly. Not only can drinking cause temporary complications such as memory loss and coordination, it can also lead to long-term side effects that are sometimes irreversible.

Prolonged and excessive alcohol use can interfere with how the brain functions, as well as how it’s structured. Damage to different regions of the brain, especially the cerebellum, limbic system and cerebral cortex, can significantly impact the body’s communication pathways. For example, the cerebellum handles your body’s motor skills. When alcohol affects this area of the brain, you’re more likely to experience a loss of balance, as well as memory and emotional response issues.


The heart is extremely vulnerable to the negative effects of alcohol consumption. Over time, heavy drinking can weaken the heart, impacting how oxygen and nutrients are delivered to other vital organs in your body. Excessive alcohol consumption can increase triglyceride levels – a type of fat in your blood. High levels of triglycerides contribute to the risk of developing dangerous health conditions such as heart disease and diabetes.

Some of the early cardiovascular effects, like high blood pressure and an irregular heartbeat, can lead to a host of problems down the road. Long-term consequences of excessive drinking may include cardiomyopathy, stroke and sudden cardiac death.


Heavy drinkers are at risk of harmful, potentially life-threatening liver problems. When you drink, your liver breaks down alcohol and removes it from your blood. However, too much alcohol in a short period of time can overwhelm the metabolism process and lead to fatty liver. Fatty liver is a chronic condition that involves the buildup of bad fats in the liver. Obesity is one of the biggest factors of fatty liver. It can also cause liver failure and type 2 diabetes.

Other serious liver complications associated with prolonged and excessive alcohol consumption are alcoholic hepatitis, fibrosis and cirrhosis. While each of these conditions is treatable, they require a proper medical diagnosis and intensive treatment plan.


The pancreas is part of the digestive process and helps regulate your body’s blood sugar levels. Drinking alcohol over many years can start to negatively impact your pancreas and cause lasting health complications. Unfortunately, the early stages of many pancreatic conditions are often unfelt and therefore, left untreated.

Long-term alcohol abuse can eventually cause the blood vessels around the pancreas to swell, leading to pancreatitis. This greatly increases your risk of developing pancreatic cancer – a type of cancer that spreads rapidly and is very dangerous. Symptoms of an acute pancreatic attack may include abdominal pain, diarrhea, nausea, fast heart rate and fever. While medications and other treatment methods can help manage the effects of pancreatitis, it is very difficult to reverse the condition.

Side Effects of Alcohol Abuse

There are various short- and long-term side effects associated with drinking excessively. The symptoms you may experience often depend on the amount of alcohol consumed. For example, lower to moderate consumption amounts typically involve less severe effects than drinking greater quantities.

Several short-term side effects of alcohol abuse include:

  • Slurred speech
  • Vision impairment
  • Lack of coordination
  • Extreme shifts in mood
  • Memory lapses
  • Slowed breathing

While some people may experience multiple side effects, others may face fewer complications. Unfortunately, the effects of heavy drinking affects more than the person struggling with alcohol abuse – it affects the people around them. It can directly impact your friends, family and colleagues. Even the short-term effects of drinking can cause extensive harm, ranging from driving under the influence (DUI) and criminal activities to unintentional self-harm.

In addition to the short-term, visible side effects of alcoholism, there are also long-term effects. Individuals who consume alcohol over a prolonged period are more at risk of developing these complications. Symptoms gradually surface over the course of months and years.

The long-term side effects associated with heavy drinking are:

  • Cardiovascular diseases
  • Liver disease
  • Respiratory infections
  • Cancer
  • Nerve Damage
  • Ulcers

These long-term side effects of alcoholism can impact other areas of your life such as relationship problems with family or friends, legal trouble, financial issues and poor performance at work or in school.
