Dear Sir during my annual medical check up it is found my SGPT level is 175 please let me know is it dangerous?

Extremely. You have hepatitis B, hepatitis C, Wilson's, hemochromatosis, or autoimmune hepatitis until proved otherwise. Each of these is likely to kill you unless it's treated, which is usually possible. Now, it may just be something minor like too much alcohol, allergy to ibuprofen, or even not enough exercise. But you'll need to find the cause with your physician's help.
