Nausea, weakness. Of cold atmosphere?

I started having problems like nausea in 2014, so I went to doctor, he suggested some tests. As per my ultrasound report it was clear that I have HEPATOMEGALY at that time, my liver was enlarged in shape. So doctor prescribed me some medicines and I took it for the prescribed time. In later 2019 I felt the same problem and went to doctor, and had some tests. Now in my ultrasound report, Liver was normal in size and nothing was abnormal but in my blood report SGPT and SGOT levels were increased upto 83 and 69 respectively. I started having some prescribed medicines and stopped after some time. Now in 2020 I'm again feeling the problems of nausea and weakness, so without counsulting any doctor I myself went to pathology and had test for SGPT and the result was 202, which is 3 times more than normal. Please suggest me what should I do ? I belong from Barabanki, UP but work in uttarakhand (in a hill area, more than 4500 ft) Is the problem presists and increases because of cold atmosphere ?
