What is ALT (Alanine Aminotransferase)?

Alanine Aminotransferase (ALT) is a type of enzyme. This enzyme is also found in different parts of our body, but it is predominantly located in our liver. It is also called serum glutamic pyruvictransaminase (SGPT). The human body uses the ALT enzyme to convert the food it consumes into energy. If your doctor thinks there is a problem with your liver health, he or she may order a blood test. Elevated ALT results may indicate that you have a liver problem. This test is requested to find out liver damage and apply an appropriate treatment.

How is the ALT (Alanine Aminotransferase) Test Done?

In order to have this test, it is appropriate to donate blood on an empty stomach in the morning. For 48 hours before the test, alcohol or medications that are eliminated from the liver should not be consumed, and foods containing calories should not be consumed.
ALT value can be checked from a blood sample taken from any vein in the arm.

ALT (Alanine Aminotransferase) Height
Why Does It Happen?

First of all, let's state this; A high ALT value may not always be due to a serious disease. This is because other factors may also cause your ALT values ​​to be high.

A healthy ALT level can vary depending on a variety of factors, including:

Age,
Gender,
Kilo,
Race
Your doctor takes these factors into consideration when evaluating your test results.

Elevated ALT (Alanine Aminotransferase) may be linked to the following problems;

Alcohol-Related Liver Damage:

Excessive alcohol consumption over long periods of time causes liver cells to die. Due to these losses, ALT, which is found in large amounts in the liver, passes into the bloodstream.
fatty liver,
hepatitis disease,
Cirrhosis disease,
Using medications that are toxic to your liver: The use of some medications can damage the liver and increase ALT levels. Medication use is one of the most common causes of high ALT values.
liver cancer,
Insufficient blood flow to the liver,
Iron or copper storage diseases,
Your genetic structure,
Cell damage seen in other parts of your body.
Apart from these, ALT values ​​may also be high in patients with obesity and diabetes.
 People with obesity may develop problems such as diabetes and liver infection.

Other factors that may affect the ALT value are listed as follows;

The ALT value of women during menstrual periods may change up or down,
Due to increasing age, your ALT values ​​may decrease.

Low ALT (Alanine Aminotransferase)
 Why Does It Happen?

It is a rare situation for the Alanine Aminotransferase (ALT) test result to be lower than the required level. It often does not cause any problems with your health. It does not represent any medical significance or danger. On the other hand, this may indicate vitamin B6 deficiency or a problem in the kidneys. If the ALT value is low, your doctor may order other tests to understand what problem is causing it.
However, at the point where liver failure is very advanced and eventually the liver goes bankrupt, which means that the process goes to a fatal state, the enzyme activity in the blood becomes undetectable.
