  • Interference with the brain’s communication pathways and altering the how the brain looks and works;
  • Damage to the heart - causing problems such as cardiomyopathy (stretching and drooping of heart muscle), arrhythmias (irregular heart beat), stroke and/or high blood pressure 
  • Damage to the liver - causing problems such as steatosis (fatty liver), alcoholic hepatitis, fibrosis and/or cirrhosis
  • Damage to the pancreas - alcohol causes the pancreas to produce toxins that can lead to pancreatitis (a dangerous inflammation and swelling of the blood vessels in the pancreas that prevent proper digestion)
  • Cancer - alcohol consumption can lead to certain cancers such as head and neck cancer, esophageal cancer, liver cancer, breast cancer, and/or colorectal cancer
  • Weaken the immune system - drinking too much can weaken your immune system, making your body a much easier target for disease and it can slow your body’s ability to ward off infections – even up to 24 hours after getting drunk
  • Alcohol poisoning - consequence of drinking large amounts of alcohol in a short period of time
