The liver is an essential organ that plays a critical role in maintaining overall health. Through this article, we’ll explore its key functions, what can compromise its health, and preventive measures. This discussion includes insights from Dr. Parul Garg’s informative series on liver health.

Main Functions of the Liver

  1. Metabolism: The liver processes nutrients from the food we eat, converting them into energy and essential components for our bodies.
  2. Detoxification: It filters toxins from the blood, including medications, alcohol, and environmental pollutants, breaking them down for safe elimination.
  3. Protein Synthesis: The liver produces vital proteins, including those that help clot blood and transport substances through the bloodstream.
  4. Bile Production: It makes bile, crucial for digesting and absorbing fats and fat-soluble vitamins in the small intestine.

Common Threats to Liver Health

Several factors can impair liver function:

  • Alcohol Abuse: Excessive drinking can lead to fat build-up, inflammation, and scarring of the liver.
  • Fatty Liver Disease: Often associated with obesity and diabetes, it’s characterized by fat accumulation in the liver.
  • Viral Infections: Hepatitis viruses (B, and C) can cause inflammation and long-term damage to the liver.
  • Toxins and Drugs: Certain medications and toxins can cause liver damage if not properly metabolized.

Preventive Measures

Maintaining liver health involves:

  • Regular Exercise: Helps to manage weight and reduce fat accumulation in the liver.
  • Balanced Diet: Eating a diet high in fruits, vegetables, and healthy fats can support liver function.
  • Moderate Alcohol Consumption: Limiting alcohol intake is crucial to prevent liver damage.
  • Regular Check-Ups: Including liver function tests to catch and manage problems early.
