I have been underweight for many years. due to some personal reasons, I’ve gone for psychotherapy and after series of counselling, I’m quite alright and started working out hoping to gain weight. Within 6 months, I’ve gained 10kg. So when I wanted to find out my health status, I went for screening and these problems were surfaced. Not sure if it’s due to my diet and working out.  I need to eat more and workout in order to gain weight.  I’m currently 1.57m, 52kg.  I was previously 43kg (in Sept 2016).  I wish to increase and maintain my BMI to the normal range.
