SGPT (ALT): The Liver Enzyme You Need to Monitor

If you've ever looked at a Liver Function Test (LFT) report, you've seen the acronym SGPT (also known as ALT). For doctors, this single number is the loudest alarm bell for liver distress.

\n\n

What is SGPT?

\n\n

Serum Glutamic Pyruvic Transaminase (SGPT) is an enzyme found almost exclusively inside your liver cells. It helps your liver break down proteins into energy. When your liver is healthy, SGPT stays happily inside the liver cells, and only a tiny, baseline amount is found floating in your bloodstream.

\n\n

Why Does It Leak?

\n\n

When your liver cells are damaged, inflamed, or dying, they burst open. When they burst, they spill their contents—including SGPT—directly into the bloodstream. Therefore, a high SGPT level in a blood test is a direct, undeniable sign of active liver damage.

Common Causes of High SGPT in India

\n\n

\n
• Fatty Liver Disease (NAFLD): The most common cause today, driven by obesity and high-carb diets.
\n
• Alcoholic Liver Disease: Regular, heavy alcohol consumption damages liver cells.
\n
• Hepatitis: Viral infections (like Hepatitis B or C) cause severe liver inflammation, often sending SGPT levels skyrocketing into the hundreds or thousands.
\n
• Medications: Regular use of painkillers (like paracetamol) or certain cholesterol drugs can stress the liver.

If your SGPT is even slightly elevated, do not ignore it. It is your liver crying out for help while there is still time to reverse the damage. Book an LFT with BookMyPatho today.
