Heavy and excessive alcohol use can lead to adverse side effects, including long-lasting and harmful health conditions.

More than 140,000 people die each year from alcohol-related causes. Alcohol is also responsible for over 18% of emergency room visits, making it one of the leading preventable causes of injury. Despite its dangers, alcohol use is quite common, making it very important that people know the risks of using alcohol.

How Alcohol Harms the Body

Alcohol harms the body in many ways, especially when used over prolonged periods of time. It is a toxic chemical causing inflammation throughout the body. Alcohol’s negative effects are systemic, affecting virtually every system of the body in some way. This makes the harmful effects of alcohol wide-ranging, leading to several diseases you might not suspect alcohol would cause.

8 Common Conditions Linked to Alcohol Use

Liver Disease

Long-term alcohol use causes liver damage that progresses through three distinct stages. The first stage, called fatty liver disease, does not typically cause major symptoms beyond fatigue and weight changes, but it does set the stage for more severe conditions. The fat buildup that this condition causes can lead to inflammation in the liver, called hepatitis. 

Hepatitis marks a serious progression of alcohol-related liver damage. It can cause more serious liver-related symptoms and lead to permanent scarring. This permanent scarring is the third stage of liver damage caused by alcohol, called cirrhosis. Cirrhosis is irreversible and can only be treated by getting a liver transplant.


Alcohol increases your risk of type 2 diabetes. This condition happens when your body’s cells become less sensitive to insulin, the hormone that helps sugar move from your bloodstream into your cells. It ultimately results in high levels of sugar in your bloodstream. This causes damage to circulation and nerves and can cause serious metabolic complications that can be fatal if not treated.

While medical researchers don’t fully understand exactly how alcohol causes type 2 diabetes, they know that it increases the risk of this problem. Type 2 diabetes can lead to infections, increased risk of heart attacks and strokes, kidney problems and blindness.


Alcohol’s inflammatory effects can impact the pancreas. This long, thin organ releases digestive enzymes and helps control your metabolism. Inflammation of the pancreas is called pancreatitis.

Pancreatitis is incredibly painful and worsened by the presence of food in the digestive tract, making it almost impossible to eat. If untreated, it can also lead to many other complications, several of which are potentially fatal. Someone with pancreatitis will require hospitalization to treat the condition fully.

Cardiovascular Conditions

Alcohol increases your blood pressure whenever you drink. When used for long periods of time, this leads to chronically high blood pressure, called hypertension. Hypertension causes damage to your arteries, increasing the risk of several different cardiovascular conditions.

The damage alcohol causes increases the risk that a blood clot will obstruct circulation in your heart, causing a heart attack, or in your brain, causing a stroke. It can also increase the risk of damage to your heart muscle, called cardiomyopathy, and can cause peripheral arterial disease, which affects circulation in your extremities. 

Alcoholic Gastritis

Alcoholic gastritis is inflammation of the stomach caused by chronic use of alcohol. Alcohol irritates the lining of the stomach, causing bloating and discomfort. Over time, it can lead to damage to the stomach wall that can cause internal bleeding or serious infections.


Alcohol increases the risk of gout occurring and the frequency of gout attacks. Gout is a painful joint condition caused by excessive levels of uric acid. In high concentrations, uric acid forms sharp, pointed crystals within joints. This causes damage and severe pain each time you move the joint. Alcohol can increase uric acid levels, growing the risk that you will get gout or experience a flare if you already have gout.

Neurological Disorders

Alcohol can lead to many different neurological disorders. One major neurological problem it can cause indirectly is traumatic brain injury (TBI). Up to 50% of people who experience a TBI were drunk when the injury occurred, making drinking a major risk factor for experiencing a TBI.

The other major neurological condition alcohol can cause is called Wernicke-Korsakoff syndrome. This condition develops because alcohol creates a nutritional deficiency of vitamin B1, also called thiamine. Prolonged thiamine deficiency causes inflammation in the brain, called Wernicke’s encephalopathy. This condition is reversible but will eventually become permanent if untreated, creating a form of dementia or memory loss called Korsakoff syndrome.


Alcohol increases your risk of many different types of cancer. The types of cancer that heavy drinking is connected with include:

  • Oral cancer
  • Laryngeal cancer 
  • Esophageal cancer
  • Colorectal cancer
  • Liver cancer
  • Breast cancer
  • Stomach cancer
  • Pancreatic cancer
  • Prostate cancer

The risk of developing cancer will differ for each individual; however, it will generally correlate with the amount of alcohol routinely used.

How To Prevent Diseases Caused by Alcohol

Preventing diseases is never completely possible; however, a healthy lifestyle can significantly reduce the risk of developing these diseases. General tips for avoiding diseases caused by alcohol include:

  • Eating healthy: A nutritious diet low in sugars and high in healthy foods promotes your health and reduces the risk of disease
  • Staying active: Regular exercise helps your body function at an optimal level and keeps you healthy. 
  • Maintaining a healthy weight: Achieving and maintaining a healthy weight greatly reduces your risk of many diseases.
  • Avoid alcohol: Alcohol increases your risk of disease in many different ways. Avoiding it will promote your health.

While you can take steps to maintain a healthy lifestyle, if you are still drinking, it is like putting both water and gas on a fire at the same time. You will need to stop drinking alcohol to see your risk of disease truly reduced.
