Liver and Gas problem. Please help.

Hi I conducted a routine pathology test and i got some slight issue in liver ASPARTATE AMINOTRANSFERASE (SGOT ) PHOTOMETRY is 40.9 where U/l  should be < 37 And ALANINE TRANSAMINASE (SGPT) PHOTOMETRY is 50.7 where U/l 13-40. Also I get headache in a frequency of one in every two weeks and primary reason is Gastric problem. Means I can feel that it is gas which travels to my head and create problem. I have been diagnosed with jaundice somewhere in 2009. It was not major but since then I have this headache and gas issue. Also from last one year I am putting up the weight like anything. I gained around 5 kgs in last two years. From last 4 months I am exercising and taking a healthy diet but will cannot reduce the weight. Please help.
