Understanding liver health: the ultimate guide

Maintaining liver health is crucial for overall well-being, as the liver performs essential functions that keep the body running smoothly. In this guide, we will explore the differences between a healthy and unhealthy liver, common liver problems and their manifestations, how to interpret liver test values, and how to maintain optimal liver health.

Healthy liver vs. unhealthy liver

A healthy liver efficiently performs various functions, including detoxification of harmful substances, production of bile for digestion, and storage of essential nutrients and vitamins. It is resilient and capable of regenerating damaged tissues, ensuring long-term health and functionality.

An unhealthy liver, on the other hand, struggles to perform these critical functions, which can lead to a range of health issues. Causes vary from poor diet, excessive alcohol consumption, and viral infections to chronic diseases.

An unhealthy liver may become inflamed, scarred (a condition known as fibrosis), or develop fatty liver deposits, leading to conditions like non-alcoholic fatty liver disease (NAFLD), cirrhosis, and hepatitis.

Recognising the signs of liver problems early can help in seeking timely medical intervention and prevent further complications. Continue reading to learn how you can identify if your liver is not performing optimally.

Symptoms of an unhealthy liver

Fatigue and weakness 

Chronic fatigue and weakness are common signs of liver problems. When the liver is not able to detoxify the body effectively, toxins build up, leading to a general feeling of tiredness and lack of energy.

Jaundice

Jaundice is a condition where the skin and the whites of the eyes turn yellow. This occurs due to the buildup of bilirubin, a yellow pigment that the liver normally processes and eliminates. Elevated bilirubin levels indicate liver problems.

Abdominal pain and swelling

Pain or swelling in the upper right abdomen can be a sign of liver inflammation or enlargement. This liver pain is often described as a dull ache or a feeling of fullness.

Dark urine and pale stools

Dark urine and pale stools are also indicators of liver dysfunction. The liver produces bile, which helps in the digestion of fats. When bile production or flow is disrupted, it can change the colour of urine and stools.

Nausea and vomiting

Persistent nausea and vomiting can occur when the liver fails to filter toxins from the blood properly. This can also lead to a loss of appetite and subsequent weight loss.

Itchy skin

Itchy skin, or pruritus, is another symptom of liver disease. It is thought to be caused by the buildup of bile salts under the skin.

Swelling in the legs and ankles

Fluid retention that leads to swelling in the legs and ankles is a common symptom of liver disease. This condition, known as oedema, occurs when the liver is unable to produce enough albumin, a protein that helps maintain fluid balance in the body.

Bruising and bleeding

An unhealthy liver can affect the production of clotting factors, making you more prone to bruising and bleeding. This happens because the liver produces proteins essential for blood clotting.

Advanced symptoms of liver disease

Confusion and cognitive impairment

As liver disease progresses, toxins can accumulate in the brain, leading to a condition known as hepatic encephalopathy. Symptoms include confusion, memory loss, and personality changes.

Ascites

Ascites is an accumulation of fluid in the abdominal cavity, often resulting from severe liver damage like cirrhosis. It causes noticeable abdominal swelling and discomfort.

Spider angiomas

Spider angiomas are small, spider-like blood vessels visible under the skin. They are often a sign of liver cirrhosis and other chronic liver conditions.

Does an unhealthy liver hurt?

Liver pain is typically felt in the upper right quadrant of the abdomen. It can be a dull ache or sharp pain, depending on the underlying cause. However, not all liver conditions cause pain.

Many liver diseases are asymptomatic in the early stages, making regular medical check-ups and liver function tests crucial for early detection.

Understanding liver values

Liver function tests are crucial tools for assessing liver health. These tests measure the levels of enzymes, proteins, and other substances in the blood that indicate how well the liver is functioning.

Here, we will help you understand the key components of liver function tests, how to interpret them, and what the results can indicate about liver health.

Key liver function tests

Alanine transaminase (ALT)

ALT is an enzyme found mainly in the liver. High levels of ALT in the blood often indicate liver damage, as this enzyme is released into the bloodstream when liver cells are damaged.

• Normal Range: 7-56 units per litre (U/L)
• Slightly Elevated: 57-150 U/L
• Indicative of Disease: Above 150 U/L

Aspartate transaminase (AST)

AST is an enzyme found in the liver and other organs like the heart and muscles. Elevated AST levels can indicate liver damage, but since AST is present in other tissues, it’s not as specific to the liver as ALT.

• Normal Range: 10-40 U/L
• Slightly Elevated: 41-100 U/L
• Indicative of Disease: Above 100 U/L

Alkaline phosphatase (ALP)

ALP is an enzyme related to the bile ducts; high levels can indicate blocked bile ducts or other liver-related issues.

• Normal Range: 44-147 U/L
• Slightly Elevated: 148-300 U/L
• Indicative of Disease: Above 300 U/L

Gamma-glutamyl transferase (GGT)

GGT is an enzyme in the liver and bile ducts. High levels can indicate liver disease, bile duct problems, or chronic alcohol abuse.

• Normal Range: 9-48 U/L
• Slightly Elevated: 49-150 U/L
• Indicative of Disease: Above 150 U/L

Bilirubin

Bilirubin is a substance produced by the breakdown of red blood cells. High levels can indicate liver dysfunction or bile duct problems, leading to jaundice.

• Normal Range: 0.1-1.2 milligrams per decilitre (mg/dL)
• Slightly Elevated: 1.3-3.0 mg/dL
• Indicative of Disease: Above 3.0 mg/dL

Albumin

Albumin is a protein produced by the liver. Low levels can indicate chronic liver disease, malnutrition, or other conditions.

• Normal Range: 3.5-5.0 grams per decilitre (g/dL)
• Slightly Low: 2.8-3.4 g/dL
• Indicative of Disease: Below 2.8 g/dL

Total protein

Total protein measures the combined levels of albumin and globulin in the blood. Low levels can indicate liver disease, kidney disease, or malnutrition.

• Normal Range: 6.3-7.9 g/dL
• Slightly Low: 5.5-6.2 g/dL
• Indicative of Disease: Below 5.5 g/dL

Interpreting liver function test results

Mild deviations from the normal range

Mild deviations in liver enzymes can occur due to various reasons, including medications, alcohol consumption, or fatty liver disease. Considering these results alongside clinical symptoms and other diagnostic tests is essential.

• ALT and AST: mild elevations can be caused by muscle injuries, alcohol use, or medications.
• ALP: slight increases may indicate bile duct problems or bone disorders.
• GGT: mildly elevated levels can suggest alcohol use or minor liver issues.
• Bilirubin: slight elevations can occur with mild liver dysfunction or Gilbert’s syndrome, a benign liver condition.
• Albumin and total protein: slightly low levels can result from temporary illnesses or nutritional deficiencies.

Significant deviations from the normal range

Significant deviations often indicate more serious liver conditions, such as hepatitis, cirrhosis, or liver cancer. These require further investigation and prompt medical intervention.

• ALT and AST: markedly high levels usually suggest acute liver damage from conditions like viral hepatitis, drug-induced liver injury, or severe alcoholic hepatitis. 
• ALP: high levels can indicate serious bile duct obstruction, liver disease, or bone disease.
• GGT: significantly elevated levels can point to chronic liver disease, bile duct obstruction, or heavy alcohol consumption.
• Bilirubin: high levels are typically seen in liver disease, bile duct obstruction, or haemolytic anaemia.
• Albumin and total protein: low levels are often associated with chronic liver disease, severe malnutrition, or chronic illnesses.

Importance of context in interpretation

While liver function tests provide valuable information, it’s essential to interpret them in the context of the patient’s overall health, symptoms, and medical history.

For instance, elevated liver enzymes in a patient with known liver disease may indicate disease progression, while similar elevations in an asymptomatic patient may require further diagnostic workup.
