The Effects of Alcohol on the Body

Whether it’s wine at a celebratory dinner, spirits and liquors during the holidays or a few beers after a long work week, drinking alcohol has become part of American culture. Alcohol consumption is not only prevalent in American culture but drinking alcohol and eating food is an established norm for celebrations and special occasions in most cultures throughout the world.

Occasional or social drinking may seem harmless. However, each time someone drinks alcohol, they are damaging their body. The frequency and amount of alcohol that someone drinks can determine the severity of the effects of alcohol on the body.

How Alcohol Affects the Different Body Systems

Alcohol consumption doesn’t affect only one system or organ of the body. Drinking alcohol affects every part of the body, both internally and externally.

Because everyone is different, the effects of short-term and long-term alcohol consumption can vary. Risk factors can influence the effects of alcohol on body systems. The risk factors may include:

  • The amount of alcohol consumed
  • Medical history
  • Tolerance to alcohol
  • Drinking in combination with other drugs

Among other systems, alcohol directly affects the throat, stomach, heart and brain.

Effects of Alcohol on the Throat

Typically, the first part of the body that alcohol comes into contact with is the throat, and frequent or heavy drinking can damage it. Alcohol is an irritant and burns on contact. When someone drinks alcohol, they may notice a burning sensation, especially if they’re drinking a high-proof liquor.

The burn of alcohol can damage or kill the body’s living tissue. Drinking alcohol over a long period can cause severe effects of alcohol on the mouth and throat, which can lead to the development of neck and throat cancers or chronic medical problems.

The Effects of Alcohol on the Stomach

When alcohol enters the stomach, it can be absorbed in the bloodstream or pass through the intestines. However, some alcohol may do neither. If alcohol remains in the stomach, it can increase the stomach’s acidity and irritate the lining. Irritation to the stomach lining can lead to inflammation of the stomach, called gastritis, which causes ulcers and bleeding.

In addition to ulcers, alcohol consumption can interrupt the digestive system and block the absorption of folic acid, thiamin, fat, amino acids and vitamins B1 and B12. If someone experiences pain after drinking alcohol, they could have developed chronic cholecystitis, a condition in the gallbladder.

The Effects of Alcohol on the Heart

Drinking alcohol causes problems with the heart, including:

  • Inflammation: Short-term alcohol consumption can cause inflammation of the heart’s muscle walls
  • Arrhythmia: Binge drinking and drinking for a long period can disrupt the heart’s rhythm causing the heartbeat to speed up or become irregular which can cause a condition called arrhythmia.
  • Cardiomyopathy and myocarditis: In addition to affecting the heartbeat, other conditions can develop including cardiomyopathy and myocarditis.
  • Increased risk of heart attack: Drinking alcohol also raises blood pressure and blood lipids. When these levels are increased, there is a higher risk of a heart attack, hypertension, high cholesterol and a stroke.

The Effects of Alcohol on the Brain

There are several distinct effects of alcohol on the brain. A short-term problem may be temporary memory loss or blackouts and complications with coordination. The chemical reaction in the brain is also what makes alcohol addictive. Alcohol releases dopamine in the brain and provides a feeling of pleasure and euphoria.

Wernicke-Korsakoff Syndrome

Drinking alcohol for an extended period may also lead to the development of Wernicke-Korsakoff Syndrome, which affects memory, speech, vision and could cause seizures. Drinking an excessive amount of alcohol can produce too much dopamine and gamma-Aminobutyric acid (GABA), which can cause:

  • Shortness of breath
  • High blood pressure
  • Increased heart rate
  • Delusions
  • Hallucinations
  • Spasms
  • Aggression
  • Depression

Endorphins are also released when someone is drinking alcohol which can reduce pain and increase feelings of happiness. The production of too many endorphins can lead to:

  • Depression
  • Lower sex drive
  • Low testosterone
  • Infertility
  • Fatigue

Alcohol and Weight Gain

In addition to causing health problems internally, alcohol consumption may also cause someone to gain weight. People may forget that most alcohol has calories, so if someone drinks an excessive amount of alcohol frequently, they are consuming extra calories that often turn into fat.

In addition to how alcohol contains empty calories, alcohol is often referred to as an appetite stimulant. Alcohol can cause someone to eat larger amounts of food than they normally would and make poor choices when selecting meals.
