How to Lower Your ALT Levels: A Comprehensive Guide
Alanine aminotransferase (ALT) is an enzyme found primarily in the liver, but also in smaller amounts in the kidneys, heart, and muscles. When liver cells are damaged, ALT is released into the bloodstream, causing ALT levels to rise. Elevated ALT levels can be an indicator of liver damage or disease. While a doctor is the best resource to determine the cause of high ALT and create a treatment plan, there are several lifestyle adjustments and dietary changes that can help lower ALT levels. This comprehensive guide will walk you through the steps you can take to support your liver health and reduce your ALT levels. Remember to consult with your healthcare provider before making significant changes to your diet or lifestyle, especially if you have underlying health conditions.
Understanding ALT Levels and Liver Health
Before diving into how to lower ALT levels, it’s essential to understand what they represent. ALT is measured in units per liter (U/L). Normal ALT ranges vary slightly between laboratories, but generally, a normal range is considered to be between 7 and 55 U/L. It’s important to review your lab results with your doctor to determine what’s considered normal for you, and to understand the significance of your specific results.
Elevated ALT levels can be caused by a variety of factors, including:
* **Non-alcoholic fatty liver disease (NAFLD):** This is the most common cause of elevated ALT levels, particularly in individuals who are overweight or obese.
* **Alcohol-related liver disease:** Excessive alcohol consumption can damage the liver and lead to increased ALT levels.
* **Viral hepatitis:** Hepatitis A, B, and C can cause liver inflammation and elevated ALT.
* **Medications:** Certain medications, such as statins, pain relievers (like acetaminophen), and antibiotics, can cause liver damage and increase ALT.
* **Supplements:** Some herbal supplements, like kava and chaparral, can be toxic to the liver.
* **Autoimmune hepatitis:** This is a condition in which the body’s immune system attacks the liver.
* **Hemochromatosis:** This is a genetic disorder that causes the body to absorb too much iron, which can damage the liver.
* **Wilson’s disease:** This is a rare genetic disorder that causes copper to accumulate in the liver, brain, and other organs.
* **Alpha-1 antitrypsin deficiency:** This is a genetic disorder that can cause liver and lung disease.
* **Celiac disease:** This autoimmune disorder can sometimes affect the liver.
* **Obesity:** Even without NAFLD, obesity itself can contribute to slightly elevated ALT levels.
It’s important to note that mildly elevated ALT levels don’t always indicate a serious problem. Sometimes, they can be caused by temporary factors like intense exercise or a recent infection. However, persistently elevated ALT levels should be investigated by a doctor to determine the underlying cause.
