Liver Health

Overview

The liver is the second largest organ in your body and has many functions. It processes what you eat and drink into energy and nutrients that are then distributed to the rest of your body either for utilization or storage. The liver also detoxifies harmful substances from your blood and manufactures clotting factors amongst other proteins and also supports the  immune system.

Common causes of liver disease

  • Viruses (including hepatitis A, B, C, D E)
  • Hereditary and metabolic causes (Hemochromatosis, Wilson’s Disease)
  • Auto-immune related disorders
  • Alcohol and obesity
  • Adverse reactions to medications or toxins

 

Symptoms of Liver Disease

There are usually no symptoms in the early or mild stages of liver disease.

Symptoms of cirrhosis or acute liver failure may include:

  • Jaundice
  • Loss of appetite
  • Tiredness
  • Nausea
  • Weight loss
  • Abdominal bloating and pain

 

What is inflammation of the liver?

Inflammation (swelling) of the liver, also known as hepatitis, is usually the first stage of liver disease. Inflammation is generally a sign that the body is trying to fight an infection or heal an injury. Severe inflammation can occur in a short space of time leading to acute liver failure or it can rumble on for many years at a more slow or moderate level  eventually can cause scarring in the liver called fibrosis or cirrhosis. Inflammation is often diagnosed through blood tests and if diagnosed early, can be treated and is reversible.

What is liver fibrosis and cirrhosis?

If inflammation of the liver persists over many years, fibrosis or scarring of the liver develops. Fibrosis, or scar tissue, replaces healthy liver tissue. As scar tissue builds up, the architecture and functioning of the liver are affected. Cirrhosis is the most advanced stage of liver fibrosis. Fibrosis and cirrhosis can be diagnosed using non-invasive tools such as Fibroscan liver stiffness measurement, liver biopsy, blood test scoring systems and imaging tests.

How does a healthy diet help the liver?

Eating a healthy diet and maintaining a healthy weight and body mass index helps the liver to do perform optimally. Eating more than the recommended caloric intake per day, a sedentary lifestyle and overall weight gain contributes to being overweight, obesity and non-alcoholic fatty liver disease (NAFLD) which is the most common liver disease in the world today.  NAFLD is increasingly becoming one of the most common causes for patients requiring liver transplant in the world.

  • Avoid eating uncooked food
  • Avoid fructose containing foods such as high fructose corn syrup found in canned drinks and many confectionaries.

How can alcohol affect the liver?

Alcohol causes build up of fat in your liver (fatty liver), inflammation or swelling of your liver (alcoholic hepatitis), and eventually scarring of your liver (cirrhosis). Recently, the guidelines for acceptable alcohol consumption have been lowered to 14 units per week for both men and women.
