So I ve been experiencing palpitations, confusion & fatigue for a while now, I thought It was because of iron deficiency but I ve overcome that according to doctor, he said that my liver function levels were slightly abnormal as I had a GGT of 34 when range was 30, I also had slight increase in bilirubin and albumin, I have never had alcohol and am active on most weekends, I m 19 years old and very skinny (have always been skinny), I was very sporty and athletic when I was younger, I also always experience weird feeling as if something is always in my neck. The biggest issue is the palpitations as they re really annoying and I ve also experienced them for a while, any idea with whats wrong with me as I m very very concerned
