When SGOT (AST - Aspartate Aminotransferase) is high in the bloodstream, it typically indicates liver damage or inflammation. The liver cells, when injured, release this enzyme into the blood, leading to elevated levels.
Here's a more detailed breakdown:
-
Liver Damage/Inflammation: The primary reason for elevated SGOT (AST) levels is damage or inflammation of the liver. This can stem from various causes.
-
Possible Causes:
- Acute Hepatitis: Inflammation of the liver, often caused by viral infections like hepatitis A, B, or C, is a common reason for high SGOT levels. A viral infection (like Hepatitis) causes inflammation.
- Chronic Hepatitis: Long-term inflammation of the liver, such as chronic hepatitis B or C, can also result in elevated SGOT levels.
- Alcoholic Liver Disease: Excessive alcohol consumption can damage liver cells, leading to increased SGOT.
- Non-Alcoholic Fatty Liver Disease (NAFLD) / Non-Alcoholic Steatohepatitis (NASH): These conditions, characterized by fat buildup in the liver, can cause inflammation and elevated SGOT.
- Medications: Certain medications, including over-the-counter pain relievers (like acetaminophen) and prescription drugs, can be toxic to the liver and raise SGOT levels.
- Other Liver Diseases: Conditions like autoimmune hepatitis, hemochromatosis (iron overload), and Wilson's disease (copper overload) can also damage the liver and increase SGOT.
- Muscle Injury: Since AST is also found in muscles, significant muscle injury (e.g., from intense exercise or trauma) can sometimes lead to elevated levels, although ALT is typically more specific to the liver.
- Heart Problems: While less common, heart conditions like heart attack or heart failure can sometimes cause a slight elevation in AST.
-
Symptoms: Elevated SGOT may or may not cause noticeable symptoms, especially if the elevation is mild. When symptoms are present, they may include:
- Fatigue
- Jaundice (yellowing of the skin and eyes)
- Abdominal pain
- Nausea
- Vomiting
- Loss of appetite
- Dark urine
- Pale stools
-
Diagnosis and Treatment: If a blood test reveals high SGOT levels, further investigation is necessary to determine the underlying cause. This may involve:
- Further Blood Tests: To assess other liver enzymes (like ALT, alkaline phosphatase, and bilirubin), as well as markers for specific liver diseases (e.g., hepatitis viral load).
- Imaging Studies: Ultrasound, CT scan, or MRI of the liver may be performed to visualize the liver and identify any abnormalities.
- Liver Biopsy: In some cases, a liver biopsy may be necessary to obtain a sample of liver tissue for microscopic examination.
Treatment will depend on the underlying cause of the elevated SGOT. For example:
- Viral Hepatitis: Antiviral medications may be prescribed.
- Alcoholic Liver Disease: Abstinence from alcohol is crucial.
- NAFLD/NASH: Lifestyle modifications, such as weight loss, diet changes, and exercise, are recommended.
- Medication-Induced Liver Injury: Discontinuing the offending medication.
In summary, a high SGOT level generally indicates liver damage or inflammation, necessitating further investigation to determine the cause and appropriate treatment. It's important to consult with a healthcare professional for proper diagnosis and management.
