I recently got my liver function test. SGPT value is 93 and GGT value is 80. I am concerned about my digestion issues which keeps happening since the past few months. I cannot digest any heavy or spicy food and often have indigestion or nausea after eating such food. I have been taking Liv52 since past 10-15 days two tabs a day. Please can you explain me the significance of sgpt and sgot values aslo ggt values and what would high value indicate.
