I recently went to the hospital with pain in upper abdomen and diarrhea. They did ct scan and blood work and everything seemed fine. The next day i was still feeling bad so i went to a different hospital. They took my blood again and my alt and slt and changed from the day before. So they transfered me to a hospital that was better equipped for testing. They did a MRI and everything came back fine. They also did an upper GI which was alos fine. Every other ensyme and blood test they di was fine and the hep tests came back negative. What could have caused my alt and ast levels to raise? They said they where starting to go back down aftsr 5 days in the hospital but I havent seen the results to thise tests yet. Just wondering what could have caused this?
