Short & Long-Term Effects of Alcohol Abuse/Addiction

Alcohol abuse is characterized by the habitual misuse of alcohol, whether that be heavy drinking throughout the week or binge drinking at one time. While alcohol plays a large role in many social gatherings, moderation is key. Abusing alcohol can lead to adverse effects in the short term and serious health implications in the long run.

Short-Term Effects of Alcohol Consumption

The effects of alcohol can be experienced within 10 minutes of your first sip.1 After a drink, your heart rate quickens and your blood vessels expand, giving you a warm feeling.2 After another drink or two, your decision-making and judgment are inhibited. Your nervous system also feels the effects, causing you to feel lightheaded. Further drinking leads to slurred speech, unfocused vision, impaired coordination, and drowsiness.2 Habitual drinking can lead to an unhealthy relationship between alcohol and the body, resulting in dependence or addiction. 

Binge drinking a large amount of alcohol in a short time can lead to more serious short-term effects, including:2

• Breathing problems
• Unsteady heart rate
• Lack of gag reflex (which could cause you to choke, particularly on vomit if you pass out)
• Overdose or alcohol poisoning
• Coma 
• Death

Long-Term Side-Effects of Alcohol Abuse

Your liver can only process small amounts of alcohol at a time. This means that any remaining alcohol waiting to be processed passes through other organs.3 These organs can become damaged from alcohol abuse over time, leading to significant health issues in many parts of your body. The long-term effects of alcohol on your body can include:2

• Brain damage
• Nervous system damage
• High blood pressure
• High cholesterol
• Increased risk of heart attack
• Increased risk of stroke
• Weakened immune system
• Weakened bones
• Liver disease
• Pancreatitis 
• Depression
• Dementia
• Increased risk of many types of cancer

There are also serious long-term effects of alcohol on pregnancy, including the potential of a miscarriage or stillbirth. Mixing alcohol and pregnancy can also lead to fetal alcohol spectrum disorder (FASD).3 

Long-term alcohol use can also affect the immune system, cardiovascular system, and other major organs in the body as well as brain functioning and mental health.

Effects of Alcohol Abuse on the Immune System

Long-term abuse of alcohol can lead to a misfiring and damaged immune system. This occurs because alcohol disrupts immune pathways in a strangely unique way, affecting many facets of the immune system.4 

This includes decreasing the body’s defense against infections. People who have a history of long-time misuse of alcohol have been found to be more susceptible to dangerous conditions like pneumonia.4 The immune system also has a slower response to healing, leading to slower and less complete recovery from wounds, tissue injuries, physical trauma, and after surgery.4 Patients who chronically abuse alcohol can also suffer from systemic inflammation. 

While alcohol can impair the immune system in several ways, one of the most significant impacts comes from how alcohol alters the gut microbes in the gut microbiome. These microorganisms are vital for gut function, but also play an important role in the immune system. Over time, repeated abuse of alcohol leads to damaged cells, impaired communication between cells, and leakage of microbes outside the gut, which is catastrophic for the immune system.4

Effects of Alcohol Abuse on the Cardiovascular System

Extended alcohol abuse can also lead to one or several heart issues. Consuming large amounts of alcohol or following a pattern of binge drinking over a long period has been linked to an increased risk of cardiovascular disease.5 These cardiovascular conditions can include:5

• Hypertension (high blood pressure): Causes the heart to consistently work harder to pump blood6
• Coronary heart disease: Plaque builds up on the artery walls, leading to reduced oxygen delivered throughout the body7
• Peripheral arterial disease: A condition where narrowed arteries reduce blood flow to arms and legs8 
• Cardiomyopathy: A disease of the heart which makes it harder for the heart to pump blood to the rest of the body9

The effects of alcohol on the heart are the result of several co-occurring factors. Long-term abuse of alcohol can change your risk factors (such as cholesterol levels and plaque buildup), affect blood clotting, and induce inflammation.5

Effects of Alcohol Abuse on the Kidney

Kidneys are our internal filtration system. Their job is to filter out harmful substances, like alcohol or other substances. However, when a person binge drinks or drinks heavily, the kidneys can become damaged from overactivity. In fact, heavy drinking doubles the chance of developing chronic kidney disease.10 

Another function of our kidneys is to maintain the proper amount of water in our blood. The dehydrating properties of alcohol can inhibit the kidneys’ ability to manage this crucial balance.11 Alcohol’s effects on the kidneys are multiplied if a person is also suffering from a liver disease, which is a prevalent side effect of continuous alcohol misuse. The malfunctioning liver affects how much blood the kidneys get, which then impacts how well the kidneys can function.11 This shows how the effects of alcohol abuse can spread and impact other functions in the body.

Effects of Alcohol Abuse on the Liver

The long-term effects of alcohol on the liver are well-known and well-documented. In fact, there is a specific disease that represents liver damage caused by excess alcohol intake: alcohol-related liver disease (ARLD).12 

When alcohol enters the body, the liver’s job is to filter that toxin. However, every time it filters alcohol, some liver cells die. For mild drinking, this isn’t an issue, as the liver is adept at regenerating cells. However, long-term filtering of alcohol begins to permanently damage the liver, decreasing its ability to regenerate cells.12 This leads to ARLD. 

There are three stages of ARLD:12

1. Alcoholic fatty liver disease: Fat begins to build up in the liver. While there are rarely symptoms at this stage, your doctor may discover it and see it as a sign of unhealthy drinking habits.
2. Alcoholic hepatitis: The liver becomes inflamed.13 The damage may be reversible if drinking ceases immediately.
3. Cirrhosis: The person’s liver is permanently scarred. 

A damaged liver can lead to many other health issues, including problems with digesting food, regulating blood sugar and cholesterol, and fighting infections.12

Effects of Alcohol Abuse on the Pancreas

Chronic alcohol abuse is one of the leading causes of two forms of pancreas disease: acute and chronic pancreatitis.14 Since the pancreas is important in both digestion and blood sugar regulation, these diseases can have major ramifications on the entire body.

Alcohol can affect the pancreas by blocking pancreatic ducts, destroying pancreatic tissue, and damaging cell membranes.15 As the pancreas is damaged, it may develop acute pancreatitis, which often feels like a painful, sudden attack.16 Acute pancreatitis can be extremely serious, as it has three outcomes:14,16

• The pancreas will fully regenerate, resolving the pancreatitis
• The pancreas will fail
• The inflammation from the pancreas will spread, leading to multiple organ failure

After multiple attack of acute pancreatitis, person may develop chronic pancreatitis, where the pancreas is chronically inflamed.16

Effects of Alcohol Abuse on the Brain

Consuming alcohol can result in short-term and long-term consequences for the brain. These effects occur because alcohol interferes with the brain’s communication pathways.16 The short-term effects of alcohol on the brain include:17

• Loss of balance
• Memory issues
• Speech problems 
• Loss of judgment

This clashing of alcohol and the brain can lead to violence, unsafe sex, loss of property, and accidents or falls.2 Additionally, chronic alcohol use can lead to lasting damage to the brain, including reducing the size of neurons.17 Prolonged alcohol abuse can lead to Wernicke-Korsakoff (WK) syndrome, a brain disease attributed almost exclusively to chronic alcohol misuse and severe alcohol use disorder (AUD).18

WK syndrome is the combination of two serious brain disorders, Wernicke’s disease and Korsakoff’s psychosis. It results from brain damage from long-term alcohol abuse, combined with a vitamin B1 deficiency. Symptoms of Wernicke’s disease will present themselves first, which can include confusion, lack of energy, lack of muscle coordination, and vision problems.18 

If left untreated, the person may progress to Korsakoff’s psychosis, which is untreatable. Symptoms of Korsakoff’s psychosis include severe memory issues, hallucinations, making up inaccurate stories about past events, and repetitive speech and actions.18 

Cancer Risks Due to Alcohol Abuse

There is a great deal of evidence linking alcohol abuse to higher risks of cancer. In fact, alcohol is classified as a Group 1 carcinogen, as there have been direct ties made between several types of cancer and alcohol consumption, including:19

• Liver
• Esophagus
• Oral cavity
• Pharynx
• Larynx

This is only a few of the cancers that alcohol may contribute to; breast cancer, bowel cancer, head cancer, neck cancer, pancreatic cancer, and prostate cancer have also been linked to alcohol abuse.2,19 

Scientists believe that alcohol works in several ways to increase the risk of cancer: by producing reactive oxygen species (which harm DNA, proteins, and lipids) and by increasing our intake of acetaldehyde, a likely carcinogenic.19

These alcohol-induced cancers affect a large number of people, too. In the United States, alcohol consumption was responsible for nearly 100,000 cases of cancer in 2019 and resulted in 25,000 cancer-related deaths.19 

Effects of Alcohol Abuse on Mental Health

While alcohol abuse impacts the brain in many ways, some of the most concerning effects are related to mental health. A person struggling with alcohol may develop alcohol use disorder (AUD). Along with AUD, the person may experience co-occurring disorders, most commonly:20 

• Depressive disorders
• Anxiety disorders
• Trauma- and stress-related disorders
• Sleep disorders
• Other substance use disorders

Mental health disorders and AUD feed off each other. For example, a person may have developed AUD to try and cope with an untreated psychiatric disorder. On the other hand, chronic alcohol abuse may predispose a person to develop a mental health disorder.20 

Each person with AUD will have a unique combination of mental health symptoms, often affecting their mood, motivation, and relationships. One of the best ways to address these mental health challenges is through inpatient or outpatient addiction treatment services.
