The liver is also able to perform better with a low ALT level. There are two reasons for the decrease in platelet production in people with liver diseases, namely low production of thrombopoietin and suppression in bone marrow. Knowing how to lower liver enzymes before a blood test is important so as to get an accurate result. During liver inflammation or damage these enzymes are released into the blood thus resulting in an elevated ALT level. The blood can be tested for the presence of hepatitis B and C virus and their related antibodies. Enzymes are catalysts, which means they speed up chemical reactions in your body, sometimes by a factor of a million times or more, according to Biology Reference. More common causes of elevated liver enzymes include: Over-the-counter pain medications, particularly acetaminophen (Tylenol, others) Enzymes are central to every biochemical process occurring in your body. A hormone named thrombopoietin is produced in the liver and is responsible for regulating the production of platelets. Your physician will typically address each issue separately while trying to determine the underlying factor. Both conditions can manifest from the same disease or its treatments. If abnormal liver enzymes persist despite abstinence from alcohol, weight reduction and stopping certain suspected drugs, blood tests can be performed to help diagnose treatable liver diseases. Many diseases and conditions can contribute to elevated liver enzymes. Your doctor determines the cause by reviewing your medications, your signs and symptoms and, in some cases, other tests and procedures. Raised liver enzymes and low white blood cells are two separate conditions that have several mild to severe causes and indications. However, if liver damage continues, signs may appear. Also, elevated liver enzymes in and of themselves may not cause any symptoms. Other researchers report a transient increase in liver enzymes during the weeks after the initiation of low-calorie diets (LCDs) (6– 8). Like ALT, AST is normally present in blood at low levels. AST is an enzyme that helps metabolize amino acids. Your healthcare provider may order a liver test to check for elevated liver enzymes or bilirubin. Keeping liver enzymes low means protecting your liver from toxic insults from excessive alcohol, environmental toxins, smoking, and poisons in the environment as much as possible . When the liver is damaged, ALT is released into the bloodstream and levels increase. Aspartate transaminase (AST). ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. To lower liver enzymes include: Over-the-counter pain medications, particularly acetaminophen (,.
