Does a high liver function test always mean I have liver disease?

Not necessarily. There are several factors that can cause elevated liver enzymes, including:

Medications: Certain medications can affect liver function.

Alcohol consumption: Excessive alcohol intake can damage the liver.

Fatty liver disease: This condition involves fat buildup in the liver.

Viral hepatitis: Infections like hepatitis A, B, or C can cause liver inflammation.

Autoimmune diseases: Conditions where the immune system attacks healthy tissues can affect the liver.

Muscle damage: Injuries or strenuous exercise can cause temporary spikes in liver enzymes.

• Fatigue

When should I worry when I got elevated LFT blood test results?

if you have elevated LFT (Liver Function Test) results, especially if accompanied by certain symptoms or risk factors.

What sources of worriness if LFT test in blood is high?

some sources of concern associated with high LFT results:

• Elevated LFTs may suggest liver disease, such as hepatitis, cirrhosis, or fatty liver disease.
• Liver inflammation (hepatitis) can cause abnormal LFT values.
• High LFTs might indicate infection with hepatitis B or C viruses. These viruses can affect liver function and cause inflammation. PCR HCV Test
• Heavy alcohol consumption can lead to liver damage.
• Elevated LFTs may signal alcohol-induced liver injury.
• Certain medications or exposure to toxins can affect liver function.
• LFTs help monitor the impact of medications on the liver.
• If you have a family history of liver conditions, elevated LFTs should be evaluated.
• Genetic factors can play a role in liver health.

Rapidly worsening symptoms: If you experience a sudden increase in fatigue, nausea, vomiting, or abdominal pain alongside elevated LFT results, see a doctor right away.

Jaundice: Yellowing of the skin and whites of the eyes can indicate significant liver dysfunction and requires prompt medical evaluation.

Dark urine: This can be a sign of problems with bile processing by the liver and warrants a doctor's visit.

Risk Factors:

Heavy alcohol consumption: If you drink excessively, elevated LFTs could be a sign of alcohol-induced liver damage.

History of chronic health conditions: Certain conditions like diabetes, obesity, or high blood pressure increase your risk of liver disease.

Exposure to toxins: If you work with or are frequently exposed to toxins, a doctor can assess the potential impact on your liver.
