A 2012 study published in October 2015 in the International Journal of Cancer also shows that over 5 percent of new cancer occurrences nearly 6 percent of all cancer deaths worldwide were estimated to be attributed to alcohol. According to the NCI. heavy drinkers are 5 times more likely than nondrinkers to contract esophageal cancer.

Affect Long-Term Memory and Brain Structure

Reports by the American Addiction Centers.  say that heavy drinkers over a long period of time stand the risk of long term problems with brain function as well as risk of changing the brain’s “hard wiring,” which can lead to cognitive problems even after sobriety is attained.

Cause Hormonal Disturbances

Binge drinking affects the body’s endocrine system according to research published in September 2013 in the journal Endocrine and Metabolism Clinics of North America. The study found that heavy drinking can disrupt communication between the nervous, endocrine, and immune systems with resultant effects like stress abnormalities, reproductive deficits, body growth defects, and immune dysfunction.

Change the Composition of Organisms in the Gut

Alcohol can interfere with the composition and function of microorganisms found in the body. A study published in 2015 in the journal Alcohol Research: Current Reviews found that chronic alcohol consumption can cause bacterial overgrowth and imbalances in the intestine.
