Alcohol consumption affects many of the body's organs, including the brain and heart.

Heart problems caused by alcohol consumption include cardiomyopathy, arrhythmia and hypertension.

Alcohol consumption also affects the liver by initially causing fatty build-up called steatosis, and can eventually cause cirrhosis, alcoholic hepatitis or fibrosis.
