Alcohol is a leading cause of death. Almost every part of the body is harmed when people drink large quantities of alcohol.
Nervous System - Drinking impairs the brain and other parts of the nervous system. Dementia is a decline in mental functioning. People with alcohol related dementia can reverse effects if they stop drinking.
Digestive System - Drinking increases the risk of developing cancers of the mouth, esophagus, and stomach. Drinking also increases the risk of developing liver disease. Alcohol hepatitis is a condition in which the liver swells due to alcohol.
Immune System - Drinking depresses the function of the immune system. This increases the risk of developing certain illnesses such as respiratory infections, tuberculosis, and certain cancers.
Cardiovascular System - People who drink run a greater risk of developing cardiovascular diseases, high blood pressure, and stroke. They can also develop cardiomyopathy which is a disease where the heart muscles weaken and enlarge, causing blood not to be pumped effectively.
