What are the many causes for the enzymes to be high in your liver?

alcohol consumption? what else...

and what are ways that you can lower the level?

One of the conditions is Alpha-1 Antitrypsin Deficiency Disorder (called Alpha 1). Its a rare genetic disorder that effects the liver/and or lungs in people who have it. There are different versions, some more severe depending on the alleles one has. Its a single gene recessive disorder, so in order to get it, both parents must be carriers of the recessive gene.

Other causes I know of include, drugs, medications, herbs, supplements, even teas. Other conditions that can cause it would be liver cancer I know, problems with pancreas, kidneys, viral infections.

I know that "healthy living" and time can reduce elevated liver enzymes, potentially. Drink lots of water and little else in the way of fluids. Eat healthy well balanced meals, avoid junk food, don't eat too much or too little, etc. Exercise (but not too much). Get 8 hours of good sleep every night. Reduce stress levels. Don't smoke or do drugs. Ask your doctor about any supplements or medications, all that stuff.

Antidepressants and a lot of medications in fact can affect your liver enzymes.

Alcohol, Drugs, and type of toxins that you ingest. Even taking some medications such as Tylenol alot can damage your liver. If your enzymes are high, you also want to get tested for hepatitis.

Hepatitis C and Cirrhosis of the liver will cause high enzyme count in your liver.

Hep A, B, C...etc. Basically liver disease, alcohol or other wise.
