A slew of recent studies are starting to promote alcohol as "healthy"; that is, drinking a few glasses of wine in a week. However, those that consume three or more drinks a day, may be damaging their bodies irreparably. Learn what conditions alcohol abuse may be responsible.

Pancreatitis
Pancreatitis
Heavy drinking, usually over a period of 10 years or more, is the cause of about eight out of 10 cases of chronic pancreatitis. Alcohol disrupts the digestive process by inflaming the pancreas and damaging its cells, often causing severe pain.Source:Drink Aware

Diabetes
Diabetes
Too much alcohol can cause chronic inflammation of the pancreas (pancreatitis), which can impair its ability to secrete insulin, ultimately leading to diabetes. If you already have diabetes, alcohol is even more dangerous because if your liver gets damaged (the organ that stores your glucose supply), your glucose levels may become unsteady and put you at risk for hypoglycemia.

Cirrhosis of the liver
Cirrhosis of the liver
Most people who consume alcohol do not suffer damage to the liver, but heavy alcohol use over several years can cause chronic injury to the liver. For women, consuming two to three drinks—including beer and wine—per day and for men, three to four drinks per day, can lead to liver damage and cirrhosis.

Immune system
Immune system
Drinking too much can weaken your immune system, making your body a much easier target for disease.  Chronic drinkers are more liable to contract diseases like pneumonia and tuberculosis than people who do not drink too much.  Drinking a lot on a single occasion slows your body’s ability to ward off infections – even up to 24 hours after getting drunk.
