What is SGPT (ALT)?

SGPT, also called ALT (alanine transaminase), is an enzyme found mostly in your liver. Normally only a little is in your blood, but when liver cells are irritated or damaged, more leaks out.

SGPT on your report

Listed under liver function tests (LFT) as SGPT or ALT, usually in U/L. Labs set their own range, and results vary with age, sex and weight, so check the range printed on your report.

SGPT: an enzyme found mostly in your liver.

What SGPT tells your doctor

A raised SGPT is a sign that something is bothering your liver.

Causes include:

  • hepatitis and other infections
  • alcohol
  • some medicines and supplements
  • other liver diseases

Doctors may also suspect fatty liver when ALT is raised, a condition closely linked to extra weight around the waist and diabetes.

A raised result does not always mean serious disease, but it is worth following up.

What moves your SGPT

If fatty liver is the cause, gradual weight loss is one of the most helpful steps.

Cut back on:

  • sugar and sweets
  • cold drinks
  • maida and fried snacks

Build meals around vegetables, dals, whole grains and enough protein. Regular walking helps, alcohol is best avoided, and don't take herbal or other supplements without asking your doctor.

Intense exercise just before the test can raise ALT for a short time.
