High SGPT (Serum Glutamic Pyruvic Transaminase), also known as ALT (Alanine Aminotransferase), in the liver usually indicates liver cell damage. The specific consequences depend on the degree of elevation and the duration of the elevated levels.
Implications of Elevated SGPT/ALT Levels
-
Acute Liver Problems: Very high SGPT levels can signify an acute liver issue, such as viral hepatitis (e.g., hepatitis A, B, or C), drug-induced liver injury (e.g., from acetaminophen overdose), or ischemic hepatitis (reduced blood flow to the liver).
-
Chronic Liver Disease: Mild to moderate elevation in SGPT levels, especially if it persists over time on multiple tests, can be an indicator of chronic liver diseases like:
- Non-alcoholic fatty liver disease (NAFLD) and its more severe form, non-alcoholic steatohepatitis (NASH).
- Alcoholic liver disease.
- Chronic viral hepatitis (B or C).
- Autoimmune hepatitis.
- Hemochromatosis (iron overload).
- Wilson's disease (copper accumulation).
-
Liver Inflammation and Damage: Elevated SGPT is a marker of liver cell inflammation and damage. When liver cells are damaged, they release SGPT into the bloodstream, leading to higher levels in blood tests.
-
Severity is Complex: The degree of SGPT elevation alone doesn't reliably predict the extent of liver injury. Other tests and clinical evaluation are needed.
Actions to Take If SGPT is High
- Consult a Doctor: Discuss the results with a healthcare professional. They can assess your medical history, perform a physical exam, and order additional tests to determine the cause of the elevated SGPT.
- Further Testing: Expect additional blood tests, including other liver function tests (like AST, alkaline phosphatase, bilirubin), hepatitis serologies, and tests for autoimmune liver diseases. Imaging studies (ultrasound, CT scan, or MRI) may also be necessary.
- Lifestyle Modifications: Depending on the suspected cause, lifestyle changes might be recommended, such as:
- Avoiding alcohol.
- Losing weight if NAFLD is suspected.
- Managing underlying conditions like diabetes or high cholesterol.
- Medication: If the cause is identified (e.g., viral hepatitis, autoimmune hepatitis), specific medications may be prescribed to treat the underlying condition.
- Monitoring: Regular monitoring of liver function is crucial to track the progress of the condition and the effectiveness of the treatment.
Example Scenario
If a person has an SGPT level that is twice the upper limit of normal and no other symptoms, their doctor might recommend repeat testing in a few weeks, along with checking for viral hepatitis and NAFLD risk factors. If the SGPT level is ten times the upper limit of normal and the person is jaundiced, the doctor would likely investigate acute hepatitis.
