Effects of Alcohol on the Body

Alcohol is a substance that is commonly used and abused. It causes problems for millions of Americans and their families, yet it is so difficult to stop problem drinking. Heavy drinking, either on a single occasion or over the span of weeks and months, can cause serious harm to a person’s body.

Binge Drinking and Alcoholism

Binge drinking is defined by the CDC as consuming 5 or more drinks in one sitting for men, and 4 or more drinks for women. The CDC also reports that one in six U.S. adults binge drinks about four times a month, consuming about eight drinks per binge. Even though binge drinking is more common among young adults aged 18–34 years, binge drinkers aged 65 years and older report binge drinking more often—an average of five to six times a month.

Alcoholism is a progressive disease that is characterized by regular heavy drinking, severe cravings for alcohol, continuing to drink even though it causes negative consequences, and experiencing withdrawal symptoms after stopping drinking. According to the National Council on Alcoholism and Drug Dependence, 17.6 million people, or one in every 12 adults, suffer from alcohol abuse or dependence.

Both binge drinking and alcoholism can lead to serious health risks. Alcohol is a drug that has the potential to cause permanent damage to the organs and tissues of the body, and it changes the individual’s brain chemistry.

Effects of Alcohol on the Digestive System

The first part of the body that is affected by alcohol consumption is the digestive system. As alcohol is consumed it can cause heartburn, or a reflux of acid that passes from the stomach into the esophagus. Once in the stomach, alcohol causes damage to the lining of the stomach, leading to gastritis and inflammation of the stomach wall. Alcohol can cause diarrhea or constipation, and often worsens irritable bowel syndrome. Alcoholism is known to cause poor absorption of nutrients, leading to malnutrition.

The liver, which helps cleanse the body of toxins, is taxed heavily by alcohol. Hepatitis, fatty liver, cirrhosis, and fibrosis are all problems of the liver that are due to overloading this organ with toxins. The pancreas also suffers with too much drinking, and inflammation and swelling of this organ is common among heavy drinkers.

Effects of Alcohol on the Nervous System

Excessive alcohol consumption leads to a host of problems with the nervous system. Alcohol interferes with the brain’s natural pathways for communication, and large amounts of alcohol have a more damaging effect. Nerve damage, called alcoholic neuropathy, causes pain or numbness in the extremities. Alcohol can cause neurological damage including difficulty walking, loss of motor control, slurred speech, blurred vision, slowed reaction times, blackouts, and impaired memory. Many of these symptoms are reversed once the alcohol has left the body, but some of these side effects can become permanent if the person continues drinking.

Alcoholism causes serious damage to the normal function of the brain, and also can cause changes in mood and behavior. Mental health disorders like depression, anxiety disorders, and psychosis are often made worse by drinking alcohol.

Alcohol Effects on the Cardiovascular System

Alcohol also has an impact on the cardiovascular system. Even one night of binge drinking can cause damage to the heart, and over time alcohol causes irreversible damage to this body system. Alcohol causes irregular heart beat, high blood pressure, stroke, weakening of the heart muscle, and heart disease.

Effects of Alcohol on the Immune System

Heavy drinking can cause the immune system to weaken, which makes the body more susceptible to illness and disease. Serious sicknesses like pneumonia and tuberculosis, as well as the common cold and the flu, pose a greater threat to someone whose immune system is compromised. Someone who drinks large amounts will be less able to fight off infections as well. Alcoholism is known to increase a person’s chance for developing certain cancers–in particular mouth cancer, throat cancer, liver cancer, and breast cancer.
